• Displaying data from linked tables in netbeans JTable

  - by Darc

  I have been writing in java for a few months now and have just started using netbeans. I have spent all day today trying to work out how to connect to an SQL database and display data from 2 tables (ie display the data from from a select statement with an inner join) in a JTable. I have tried using JPQL with the following statment SELECT j, cust.name FROM Job j JOIN j.jobnumber cust where the job table has a field called customer that references id in the customer table. This throws the exception: Caused by: Exception [TOPLINK-8029] (Oracle TopLink Essentials - 2.0.1 (Build b09d-fcs (12/06/2007))): oracle.toplink.essentials.exceptions.EJBQLException Exception Description: Error compiling the query [SELECT j, cust.name FROM Job j JOIN j.jobnumber cust], line 1, column 11: invalid navigation expression [cust.name], cannot navigate expression [cust] of type [java.lang.Integer] inside a query. at oracle.toplink.essentials.exceptions.EJBQLException.invalidNavigation(EJBQLException.java:430) What am i doing wrong? Can anyone point me to some examples of how to make a linked table java application? I am still in the very early stages of development so a complete change is not out of the question if using a mysql database isnt the best way to go about things thanks

• Best approach to cache Counts from SQL tables ?

  - by pixel3cs

  I would like to develop a Forum from scratch, with special needs and customization. I would like to prepare my forum for intensive usage and wondering how to cache things like User posts count and User replies count. Having only three tables, tblForum, tblForumTopics, tblForumReplies, what is the best approach of cache the User topics and replies counts ? Think at a simple scenario: user press a link and open the Replies.aspx?id=x&page=y page, and start reading replies. On the HTTP Request, the server will run an SQL command wich will fetch all replies for that page, also "inner joining with tblForumReplies to find out the number of User replies for each user that replied." select tblForumReplies.*, tblFR.TotalReplies from tblForumReplies inner join ( select IdRepliedBy, count(*) as TotalReplies from tblForumReplies group by IdRepliedBy ) as tblFR on tblFR.IdRepliedBy = tblForumReplies.IdRepliedBy Unfortunately this approach is very cpu intensive, and I would like to see your ideas of how to cache things like table Counts. If counting replies for each user on insert/delete, and store it in a separate field, how to syncronize with manual data changing. Suppose I will manually delete Replies from SQL.

• detection of 'flush tables with read lock' in php

  - by theduke0

  I would like to know from my application if a myisam table can accept writes (i.e. not locked). If an exception is thrown, everything is fine as I can catch this and log the failed statement to a file. However, if a 'flush tables with read lock' command has been issued (possibly for backup), the query I send will pretty much hang out forever. If one table is locked at a time, insert delayed works well. But when this global lock is applied, my query just waits. The query I run is an insert statement. If this statement fails or hangs, user experience is degraded. I need a way to send the query to the server and forget about it (pretty much). Does anyone have any suggestions on how to deal with this? -set a query timeout? -run asyncronous request and allow for the lock to expire while application continues? -fork my php process? Please let me know if I can provide and clarification or details.

• Selecting rows with references across tables in SQLite 3

  - by ChristianK

  Hey there, I have a problem with a SQLite photo/album database. The database contains 3 tables: Albums id name hide -------------------------- 1 Holiday 2010 1 2 Day Trip 0 Photos id file ----------------- 1 photo1.jpg 2 photo2.jpg 3 photo3.jpg 4 photo4.jpg Relation (connects photos with albums) album photo ----------------- 1 1 1 2 2 3 2 1 A photo can be assigned to zero, one or several albums. Each album has a column 'hide' that indicates, whether the photos of this album should be ignored. I'm trying to find a SELECT query that returns all photos that are not assigned to an album + all the photos that are in albums which are not hidden (i.e. that have their 'hide' value set to 0). I came up with a query that selects photos in visible albums, but I don't know how to include the photos that are not assigned to an album. SELECT file FROM photos, albums, relation WHERE photos.id = relation.photo AND albums.id = relation.album AND albums.hide = 0 This query returns photo3.jpg and the required result would be photo3.jpg photo4.jpg because photo4.jpg is not assigned to album in the Relation table. Do you know how to solve this? Thank you very much for your help!

• Database (MySQL) structuring: pros and cons of multiple tables

  - by Gideon

  I am collecting data and storing it MySQL, for: 75 variables 55 countries Each year I have, at this stage since I am building this tool created a single table, of variables / countries (storing 1 year worth of data). Next year (and for several years after that) a new set of data will be input for each country. There are therefore 3 variables in controlling data returned to a user reviewing all collected data. The general form of any query would be: Show me these specifics variables, for these specific countries, for these specific years. (Show me average age and weight, for USA and Canada, for 2012 and 2009, for example) My question is, it seems that I have two options for arranging this data: -Multiple tables where I create a table of country / variable for each year data is collected - Single table and simply add a column (field) for the year that data relates to. As far as I can tell I could make these database calls with either sructure, but is one more powerful / efficient / quicker, and why? Thanks for your consideration. It's a PDO / PHP interface if that is relevent.

• SELECT Statement without duplicate rows on the multiple join tables

  - by theBo

  I have 4 tables built with JOINS and I would like to SELECT DISTINCT rows on the setsTbl.s_id so they always show regardless if there's relational data against them or not!. This is what I have at present which displays the data but doesn't display all of but not the entire distinct row! SELECT setsTbl.s_id, setsTbl.setName, userProfilesTbl.no + ' ' + userProfilesTbl.surname AS Name, trainingTbl.t_date, userAssessmentTbl.o_id FROM userProfilesTbl LEFT OUTER JOIN userAssessmentTbl ON userProfilesTbl.UserId = userAssessmentTbl.UserId FULL OUTER JOIN trainingTbl ON userAssessmentTbl.tt_id = trainingTbl.tt_id RIGHT OUTER JOIN setsTbl ON trainingTbl.s_id = setsTbl.s_id WHERE (userProfilesTbl.st_id=@st_id AND userProfilesTbl.sh_id=@sh_id) AND (DATEPART(yyyy,t_date) = @y_date ) OR (userAssessmentTbl.o_id IS NULL) ORDER BY setName ASC, t_date ASC With this statement I get some of the rows (the ones with data against them) but as stated the s_id field does not return distinct. This following inner select statement works in part when used in SQL Query analyzer and returns pretty much the data i require s_id setName Name o_id ----- ----- ----- ------ 1 100 Barnes 2 2 100 Beardsley 3 3 101 Aldridge 1 4 102 Molby 2 5 102 Whelan 3 but not when used outside of that environment. select * from ( SELECT userProfilesTbl.serviceNo + ' ' + userProfilesTbl.surname AS Name, userProfilesTbl.st_id, userProfilesTbl.sh_id, userAssessmentTbl.o_id, setsTbl.s_id, setsTbl.setName, row_number() over ( partition by setsTbl.s_id order by setsTbl.s_id ) r FROM userProfilesTbl LEFT OUTER JOIN userAssessmentTbl ON userProfilesTbl.UserId = userAssessmentTbl.UserId FULL OUTER JOIN trainingTbl ON userAssessmentTbl.tt_id = trainingTbl.tt_id RIGHT OUTER JOIN setsTbl ON trainingTbl.s_id = setsTbl.s_id ) x where x.r = 1 Not receiving any errors just not displaying the data?

• How grouping and totaling are done into three tables using JOIN

  - by text

  Here are my tables respondents: field sample value respondentid : 1 age : 2 gender : male survey_questions: id : 1 question : Q1 answer : sample answer answers: respondentid : 1 question : Q1 answer : 1 --id of survey question I want to display all respondents who answered the certain survey, display all answers and total all the answer and group them according to the age bracket. I tried using this query: $sql = "SELECT res.Age, res.Gender, answer.id, answer.respondentid, SUM(CASE WHEN res.Gender='Male' THEN 1 else 0 END) AS males, SUM(CASE WHEN res.Gender='Female' THEN 1 else 0 END) AS females, CASE WHEN res.Age < 1 THEN 'age1' WHEN res.Age BETWEEN 1 AND 4 THEN 'age2' WHEN res.Age BETWEEN 4 AND 9 THEN 'age3' WHEN res.Age BETWEEN 10 AND 14 THEN 'age4' WHEN res.Age BETWEEN 15 AND 19 THEN 'age5' WHEN res.Age BETWEEN 20 AND 29 THEN 'age6' WHEN res.Age BETWEEN 30 AND 39 THEN 'age7' WHEN res.Age BETWEEN 40 AND 49 THEN 'age8' ELSE 'age9' END AS ageband FROM Respondents AS res INNER JOIN Answers as answer ON answer.respondentid=res.respondentid INNER JOIN Questions as question ON answer.Answer=question.id WHERE answer.Question='Q1' GROUP BY ageband ORDER BY res.Age ASC"; I was able to get the data but the listing of all answers are not present. What's wrong with my query. I want to produce something like this: ex: # of Respondents is 3 ages: 2,3 and 6 Question: what are your favorite subjects? Ages 1-4: subject 1: 1 subject 2: 2 subject 3: 2 total respondents for ages 1-4 : 2 Ages 5-10: subject 1: 1 subject 2: 1 subject 3: 0 total respondents for ages 5-10 : 1

• Database tables with dynamic information

  - by Tim Fennis

  I've googled this and found that it's almost impossible to create a database with dynamic collumns. I'll explain my problem first. I am making a webshop for a customer. It has multiple computer products for sale. CPU's HDD's RAM ect. All these products have different properties, a CPU has an FSB, RAM has a CAS latency. But this is very inconvenient because my orders table needs foreign keys to different tables which is impossible. An other option is to store all the product specific information in a varchar or blob field and let PHP figure it out. The problem with this solution is that the website needs a PC builder. A step-by-step guide to building your PC. So for instance if a customer decides he wants a new "i7 920" or whatever i want to be able to sellect all motherboards for socket 1366, which is impossible because all the data is stored in one field. I know it's possible to select all motherboards form the DB and let PHP figure out which ones are for socket 1366 but i was wondering, is there a better solution?

• Joining tables, if percentage is above certain value

  - by CluelessGerman

  My question is similar to this one: Compare rows and get percentage However, little different. I adapted my question to the other post. I got 2 tables. First table: user_id | post_id 1 1 1 2 1 3 2 12 2 15 And second table: post_id | rating 1 1 1 2 1 3 2 1 2 5 3 null 3 1 3 4 12 4 15 1 So now I would like to count the rating for each post, in the second table. If the rating has more than, lets say, 50% positive ratings than I want to get the post_id and going it to the post_id from table one and add 1 to the user_id. At the end it would return the user_id with the number of positive posts. The result for above table would be: user_id | helpfulPosts 1 2 2 1 The post with post_id 1 and 3 have positive rating, because more than 50% have ratings of 1-3. The post with id = 2 is not positive, because the rating is exactly 50%. How would I achieve this? For clarification: It's a mysql rdbm and a positive post, is one where the number of rating_ids with 1, 2 and 3 are more than half of the overall rating. Basically the same thing, from the other thread I posted above.

• Auto-creating a "link" table between 2 main tables (ex table EmployeeProject from Employee and Project tables)

  - by user573382

  Hello! I have these 2 tables, Medication containing: IDMedication, IDCategory, Name, and Supplier, containing: IDSupplier, Name. I want to automatically create a relationship table, MedicationSupplier, containing: IDMedication and IDSupplier as keys, Price, and Quantity. My idea was to have a main page where i request the following data: (Medication)Name, IDCAtegory, (Supplier)Name, Price, Quantity. I'm not sure if i'm doing the right thing here. So this is what i'm receiveing in the .php where i do the insert: $Denumire=$_POST['Denumire']; //Medication Name $IDCategorie=$_POST['IDCategorie']; //IDCategory $Nume=$_POST['Nume']; //Supplier Name $Pret=$_POST['Pret']; //Price $Stoc=$_POST['Stoc']; //Quantity And this is my insert: $q_produse = "INSERT INTO produse VALUES ('','$IDCategorie','$Denumire')"; $q_prodfurniz = "INSERT INTO produsfurnizor VALUES ('','$IDFurnizor','$Pret','$Stoc')"; mysql_query($q_produse) or die($error); mysql_query($q_prodfurniz) or die($error); mysql_close(); My main problem at the moment is that i don't know how to insert IDMedication in the relationship table. Any help / suggestions of improving my code would be greatly appreciated. Thanks!

• Reverse-engineer SharePoint fields, content types and list instance—Part3

  - by ybbest

  Reverse-engineer SharePoint fields, content types and list instance—Part1 Reverse-engineer SharePoint fields, content types and list instance—Part2 Reverse-engineer SharePoint fields, content types and list instance—Part3 In Part 1 and Part 2 of this series, I demonstrate how to reverse engineer SharePoint fields, content types. In this post I will cover how to include lookup fields in the content type and create list instance using these content types. Firstly, I will cover how to create list instance and bind the custom content type to the custom list. 1. Create a custom list using list Instance item in visual studio and select custom list. 2. In the feature receiver add the Department content type to Department list and remove the item content type. C# AddContentTypeToList(web, “Department”, ” Department”); private void AddContentTypeToList(SPWeb web,string listName, string contentTypeName) { SPList list = web.Lists.TryGetList(listName); list.OnQuickLaunch = true; list.ContentTypesEnabled = true; list.Update(); SPContentType employeeContentType = web.ContentTypes[contentTypeName]; list.ContentTypes.Add(employeeContentType); list.ContentTypes["Item"].Delete(); list.Update(); } Next, I will cover how to create the lookup fields. The difference between creating a normal field and lookup fields is that you need to create the lookup fields after the lists are created. This is because the lookup fields references fields from the foreign list. 1. In your solution, you need to create a feature that deploys the list before deploying the lookup fields. 2. You need to write the following code in the feature receiver to add the lookup columns in the ContentType. C# //add the lookup fields SPFieldLookup departmentField = EnsureLookupField(currentWeb, “YBBESTDepartment”, currentWeb.Lists["DepartmentList"].ID, “Title”); //add to the content types SPContentType employeeContentType = currentWeb.ContentTypes["Employee"]; //Add the lookup fields as SPFieldLink employeeContentType.FieldLinks.Add(new SPFieldLink(departmentField)); employeeContentType.Update(true); private static SPFieldLookup EnsureLookupField(SPWeb currentWeb, String sFieldName, Guid LookupListID, String sLookupField) { //add the lookup fields SPFieldLookup lookupField = null; try { lookupField = currentWeb.Fields[sFieldName] as SPFieldLookup; } catch (Exception e) { } if (lookupField == null) { currentWeb.Fields.AddLookup(sFieldName, LookupListID, true); currentWeb.Update(); lookupField = currentWeb.Fields[sFieldName] as SPFieldLookup; lookupField.LookupField = sLookupField; lookupField.Group = “YBBEST”; lookupField.Required = true; lookupField.Update(); } return lookupField; }

• Multiple tables\objects in one nHibernate mapping

  - by Morrislgn

  Hi Folks I am trying to create an nHibernate mapping for a class structure like so: class UserDetails{ Guid id; User user; Role role; public User UserInfo{ get;set; } public Role UserRoles{ get;set; } public Guid ID{ Get; set; } } class User{ string name; int id; public string Name{ get;set; } public int ID{ get;set; } } class Role{ string roleName; string roleDesc; int roleId; public string RoleName{ get;set; } public string RoleDesc{ get;set; } public int RoleID{ get;set; } } The underlying DB structure is similar to the tables, but there is a linking table which links user and role using their respective IDs: UserRoleLinkTable[ identity User_Role_ID (pk) userID (FK to User table) roleid (FK to Role table) ] After playing about with nHibernate this is similar to what I want to try and achieve (but it doesnt work!): <?xml version="1.0" encoding="utf-8" ?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Admin" namespace="Admin" > <class name="UserDetails" lazy="false" table="USER"> <id name="ID"> <generator class="guid"></generator> </id> <one-to-one name="UserInfo" class="User" lazy="false" cascade="none"/> <bag name="UserRoles" inverse="false" table="Role" lazy="false" cascade="none" > <key column="Role" /> <many-to-many class="Role" column="ROLE_ID" /> </bag> </class> </hibernate-mapping> I have mappings\entities which appear to work for Role and User (used in other aspects of the project) objects but how do I pull this information into one UserDetails class? The point of the user details to be able to return all this information together as one object. Is it possible to create (for want of a better description) a container using an nHibernate mapping and map the data that way? Hopefully there is enough info to help work this out - thanks in advance for all help given! Cheers, Morris

• T-SQL Script to Delete All The Relationships Between A Bunch Of Tables in a Schema and Other Bunch i

  - by Galilyou

  Guys, I have a set of tables (say Account, Customer) in a schema (say dbo) and I have some other tables (say Order, OrderItem) in another schema (say inventory). There's a relationship between the Order table and the Customer table. I want to delete all the relationships between the tables in the first schema (dbo) and the tables in the second schema (inventory), without deleting the relationships between tables inside the same schema. Is that possible? Any help appreciated.

• CSS Child selectors in IE7 tables

  - by John

  I'm trying to use the CSS child selector in IE7, and it doesn't seem to work. I have nested tables. My outer table has a class name "mytable", and I want the td's of the outer table to show borders. I don't want the inner table td's to have borders. I think I should be able to have CSS that looks like this: .mytable { border-style: solid } .mytable>tr>td { border-style: solid } But the second line seems to have no effect. If I change the second line to make it less specific, it applies to all the td's - I see too many borders. td { border-style: solid } So I think it really is just an issue with the selectors. Pages like this suggest that IE7 should be able to do what I want. Am I doing something silly? Here's the whole HTML file: <html> <head> <style type="text/css"> .mytable { border-style: solid; border-collapse: collapse;} td { border-style: solid; } </style> </head> <body> <table class="mytable"> <tr> <td>Outer top-left</td> <td>Outer top-right</td> </tr> <tr> <td>Outer bottom-left</td> <td> <table> <tr> <td>Inner top-left</td> <td>Inner top-right</td> </tr> <tr> <td>Inner bottom-left</td> <td>Inner bottom-right</td> </tr> <table> </td> </tr> <table> </body> </html>

• Using Hibernate to do a query involving two tables

  - by Nathan Spears

  I'm inexperienced with sql in general, so using Hibernate is like looking for an answer before I know exactly what the question is. Please feel free to correct any misunderstandings I have. I am on a project where I have to use Hibernate. Most of what I am doing is pretty basic and I could copy and modify. Now I would like to do something different and I'm not sure how configuration and syntax need to come together. Let's say I have two tables. Table A has two (relevant) columns, user GUID and manager GUID. Obviously managers can have more than one user under them, so queries on manager can return more than one row. Additionally, a manager can be managing the same user on multiple projects, so the same user can be returned multiple times for the same manager query. Table B has two columns, user GUID and user full name. One-to-one mapping there. I want to do a query on manager GUID from Table A, group them by unique User GUID (so the same User isn't in the results twice), then return those users' full names from Table B. I could do this in sql without too much trouble but I want to use Hibernate so I don't have to parse the sql results by hand. That's one of the points of using Hibernate, isn't it? Right now I have Hibernate mappings that map each column in Table A to a field (well the get/set methods I guess) in a DAO object that I wrote just to hold that Table's data. I could also use the Hibernate DAOs I have to access each table separately and do each of the things I mentioned above in separate steps, but that would be less efficient (I assume) that doing one query. I wrote a Service object to hold the data that gets returned from the query (my example is simplified - I'm going to keep some other data from Table A and get multiple columns from Table B) but I'm at a loss for how to write a DAO that can do the join, or use the DAOs I have to do the join. FYI, here is a sample of my hibernate config file (simplified to match my example): <hibernate-mapping package="com.my.dao"> <class name="TableA" table="table_a"> <id name="pkIndex" column="pk_index" /> <property name="userGuid" column="user_guid" /> <property name="managerGuid" column="manager_guid" /> </class> </hibernate-mapping> So then I have a DAOImplementation class that does queries and returns lists like public List<TableA> findByHQL(String hql, Map<String, String> params) etc. I'm not sure how "best practice" that is either.

• Yii - Custom GridView with Multiple Tables

  - by savinger

  So, I've extended GridView to include an Advanced Search feature tailored to the needs of my organization. Filter - lets you show/hide columns in the table, and you can also reorder columns by dragging the little drag icon to the left of each item. Sort - Allows for the selection of multiple columns, specify Ascending or Descending. Search - Select your column and insert search parameters. Operators tailored to data type of selected column. Version 1 works, albeit slowly. Basically, I had my hands in the inner workings of CGridView, where I snatch the results from the DataProvider and do the searching and sorting in PHP before rendering the table contents. Now writing Version 2, where I aim to focus on clever CDbCriteria creation, allowing MySQL to do the heavy lifting so it will run quicker. The implementation is trivial when dealing with a single database table. The difficulty arises when I'm dealing with 2 or more tables... For example, if the user intends to search on a field that is a STAT relation, I need that relation to be present in my query. Here's the question. How do I assure that Yii includes all with relations in my query so that I include comparisons? I've included all my relations with my criteria in the model's search function and I've tried CDbCriteria's together ... public function search() { $criteria=new CDbCriteria; $criteria->compare('id', $this->id); $criteria->compare( ... ... $criteria->with = array('relation1','relation2','relation3'); $criteria->together = true; return new CActiveDataProvider( get_class($this), array( 'criteria'=>$criteria, 'pagination' => array('pageSize' => 50) ));} But I still get errors like this... CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 't.relation3' in 'where clause'. The SQL statement executed was: SELECT COUNT(DISTINCT `t`.`id`) FROM `table` `t` LEFT OUTER JOIN `relation_table` `relation0` ON (`t`.`id`=`relation0`.`id`) LEFT OUTER JOIN `relation_table` `relation1` ON (`t`.`id`=`relation1`.`id`) WHERE (`t`.`relation3` < 1234567890) Where relation0 and relation1 are BELONGS_TO relations, but any STAT relations are missing. Furthermore, why is the query a SELECT COUNT(DISTINCT 't'.'id') ?

• why cant I more than two values from 3 different tables in one query

  - by zurna

  This is strange. In the news details page, I want to take a few different values from different tables with one query. However, for some strange reason, I only get two values back. So the outcome is like: <rows> <row id="4"> <FullName>Efe Tuncel</FullName> <CategoryName/> <Title>Runway Report</Title> <ShortDesc/> <Desc></Desc> <Date/> </row> </rows> If I disable fullname, then I get shortdesc but not others. Same things happens with others.

• Lookup site column not saving/storing metadata for Office 2007 documents?

  - by Greg Hurlman

  I'm having this issue on several server environments. We have a list at the site collection root. There is a site column created as a multi-value lookup on that list's Title field. This site column is used in document libraries in subsites as a required field. When we upload anything but an Office 2007 document, the user is presented with the document metadata fill-in screen (EditForm.aspx?Mode=Upload), the user fills in the appropriate data (including picking a value(s) for this lookup), and clicks "check in" - the document is checked in as expected, with the lookup field's value filled in. With an Office 2007 document, this fails. The user selected values for the lookup field do not ever make it to the server - no errors are thrown, but the field is not saved with the document. We have an event listener on these document libraries, and if we inspect the incoming SPListItem on the event listener method before a single line of our code has run, we see that the value for the lookup field is null. It smells like a SharePoint bug to me - but before I go calling Microsoft, has anyone seen this & worked around it? Edit: the only entry I see in the SP trace logs relating to the problem: CMS/Publishing/8ztg/Medium/Got List Item Version, but item was null

• What to do with lookup entities selected from drop down select ? How to send them to the service lay

  - by arrages

  I am developing a spring mvc based application. I have a simple pojo form object, the problem is that many properties will be taked from drop down lists that are populated from lookup entities, so I return the entity ID to the form object. public NewCarRequestForm { private makeId; // this are selected from a drop down. private modelId; } Should I just send this lookup entity ID to the service layer? or should I validated that this ID is correct (Somebody can send any random ID through the request) before and how? Now there is a problem if I want to validated something based on some property of the lookup entity. Do I perform a database lookup of the entity just to perform the validation? thanks.

• Oracle SQL Developer Data Modeler: What Tables Aren’t In At Least One SubView?

  - by thatjeffsmith

  Organizing your data model makes the information easier to consume. One of the organizational tools provided by Oracle SQL Developer Data Modeler is the ‘SubView.’ In a nutshell, a SubView is a subset of your model. The Challenge: I’ve just created a model which represents my entire ____________ application. We’ll call it ‘residential lending.’ Instead of having all 100+ tables in a single model diagram, I want to break out the tables by module, e.g. appraisals, credit reports, work histories, customers, etc. I’ve spent several hours breaking out the tables to one or more SubViews, but I think i may have missed a few. Is there an easy way to see what tables aren’t in at least ONE subview? The Answer Yes, mostly. The mostly comes about from the way I’m going to accomplish this task. It involves querying the SQL Developer Data Modeler Reporting Schema. So if you don’t have the Reporting Schema setup, you’ll need to do so. Got it? Good, let’s proceed. Before you start querying your Reporting Schema, you might need a data model for the actual reporting schema…meta-meta data! You could reverse engineer the data modeler reporting schema to a new data model, or you could just reference the PDFs in \datamodeler\reports\Reporting Schema diagrams directory. Here’s a hint, it’s THIS one The Query Well, it’s actually going to be at least 2 queries. We need to get a list of distinct designs stored in your repository. For giggles, I’m going to get a listing including each version of the model. So I can query based on design and version, or in this case, timestamp of when it was added to the repository. We’ll get that from the DMRS_DESIGNS table: SELECT DISTINCT design_name, design_ovid, date_published FROM DMRS_designs Then I’m going to feed the design_ovid, down to a subquery for my child report. select name, count(distinct diagram_id) from DMRS_DIAGRAM_ELEMENTS where design_ovid = :dESIGN_OVID and type = 'Table' group by name having count(distinct diagram_id) < 2 order by count(distinct diagram_id) desc Each diagram element has an entry in this table, so I need to filter on type=’Table.’ Each design has AT LEAST one diagram, the master diagram. So any relational table in this table, only having one listing means it’s not in any SubViews. If you have overloaded object names, which is VERY possible, you’ll want to do the report off of ‘OBJECT_ID’, but then you’ll need to correlate that to the NAME, as I doubt you’re so intimate with your designs that you recognize the GUIDs So I’m going to cheat and just stick with names, but I think you get the gist. My Model Of my almost 90 tables, how many of those have I not added to at least one SubView? Now let’s run my report! Voila! My ‘BEER2′ table isn’t in any SubView! It says ’1′ because the main model diagram counts as a view. So if the count came back as ’2′, that would mean the table was in the main model diagram and in 1 SubView diagram. And I know what you’re thinking, what kind of residential lending program would have a table called ‘BEER2?’ Let’s just say, that my business model has some kinks to work out!

• Database structure for ecommerce site

  - by imanc

  Hey Guys, I have been tasked with designing an ecommerce solution. The aspect that is causing me the most problems is the database. Currently the site consists of 10+ country based shops each with their own database (all residing on the same mysql instance). For the new site I'd rather all these shop databases be merged into one database so that all tables (products, orders, customers etc.) have a shop_id field. From a programming perspective this seems to make the most sense as we won't have to manage data across multiple databases. Currently the entire site generates about 120k orders a year, but is experiencing fairly heavy growth and we need to design a solution that will scale. In 5 years there may be more than a million orders per year and a database that contains 5 years order history (archiving maybe a solution here). The question is - do we use a single database, or do we keep the database-per-shop structure? I am currently trying to find supporting evidence for either avenue. The company I am designing the solution for prefer the per-shop database structure because they believe it will allow the sites to scale. But my argument is that the shop's database probably won't get that busy over the next few years that they exceed the capacity of a mysql database and a "no expenses spared" hardware set-up. I am wondering if anyone has any advice either way? Does anyone have experience with websites / ecommerce sites that have tables containing millions of records? I know there is probably not a clear answer here, but at what stage do we have too many records or too large table files to have a fast loading site? Also, if anyone has any advice on sources of information - books, websites, etc. where I can do further research, it would be highly appreciated! Cheers, imanc

• How can I create a custom OpenOffice / LibreOffice Writer table AutoFormat scheme?

  - by Merlyn Morgan-Graham

  None of the basic table AutoFormat schemes in LibreOffice Writer have both an alternation style defined and no sum column/row style defined. If they have alternation, they always seem to have sums. Because of this I'd like to define my own table scheme. What is the easiest way to accomplish this? A WYSIWYG isn't totally necessary. I am not scared of editing simple XML files as long as I have examples to work from, and if I don't have to edit base install files. If I can place them in a custom area or my user profile directory then that would be best. If there is a way to get the GUI Add functionality to properly recognize an alternation then that would also be helpful.
