• How to send html form data from one form to multiple database tables

  - by user1701556

  I am able to send html form data to database using hibernate. I am using mySQL, Hibernate, Java 1.6, Spriong 3.0. But I would like to send that same data to multiple tables in the database. My issue is that I want to use only one html form not multiple html form. I have these tables: name, address, email, login, phone_num. From this one html form I want data to go to different tables depending on what the data is. I want to do it using Hibernate so that I am not manually taking form data and inserting it in the database. Please let me know if this is possible.

• DAO design pattern and using it across multiple tables

  - by Casey

  I'm looking for feedback on the Data Access Object design pattern and using it when you have to access data across multiple tables. It seems like that pattern, which has a DAO for each table along with a Data Transfer Object (DTO) that represents a single row, isn't too useful for when dealing with data from multiple tables. I was thinking about creating a composite DAO and corresponding DTO that would return the result of, let's say performing a join on two tables. This way I can use SQL to grab all the data instead of first grabbing data from one using one DAO and than the second table using the second DAO, and than composing them together in Java. Is there a better solution? And no, I'm not able to move to Hibernate or another ORM tool at the moment. Just straight JDBC for this project.

• SQL Filter Multiple Tables Data

  - by Brad

  If it matters, I'm using Firebird 2.1 database. I have three tables, one with keywords, one with negative keywords, and the other with required keywords. I need to be able to filter the data so the output has just the keywords that meat the stipulation of not being in the negative keyword list, and IF there are any required words, then it will require the results to have those keywords in the end result. The tables are very similar, the field in the tables that I would be matching against are all called keyword. I don't know SQL very well at all. I'm guessing it would be something like SELECT keyword from keywordstable where keyword in requiredkeywordstable and where NOT in negativekeywordstable Just a side note, The required keywords table could be empty which would mean there are no required keywords. Any help would be appreciated. -Brad

• Select data from three different tables with null data

  - by user3678972

  I am new in Sql. My question is how to get data from three different tables with null values. I have tried a query as below: SELECT * FROM [USER] JOIN [Location] ON ([Location].UserId = [USER].Id) JOIN [ParentChild] ON ([ParentChild].UserId = [USER].Id) WHERE ParentId=7 which I find from this link. Its working fine but, it not fetches all and each data associated with the ParentId Something like it only fetches data which are available in all tables, but also omits some data which not available in Location tables but it comes under the given ParentId. For example: UserId ParentId 1 7 8 7 For userId 8, there is data available in Location table,so it fetches all data. But there is no data for userId 1 available in Location table, so the query didn't work for this. But I want all and every data. If there is no data for userId then it can return only null columns. Is it possible ?? hope everyone can understand my problem.

• How to create relationship between two tables with revisions using Entity Framework

  - by Chris Ridenour

  So I am in the process of redesigning a small database (and potentially a much larger one) but want to show the value of using revisions / history of the business objects. I am switching the data from Access to MSSQL 2008. I am having a lot of internal debate on what version of "revision history" to use in the design itself - and thought I had decided to add a "RevisionId" to all tables. With this design - adding a RevisionId to all tables we would like tracked - what would be the best way to create Navigational Properties and Relationships between two tables such as | Vendor | VendorContact | where a Vendor can have multiple contacts. The Contacts themselves will be under revision. Will it require custom extensions or am I over thinking this? Thanks in advance.

  Hi, I have a database wherein per day a table is created to log process instances. The tables are labeled MESSAGE_LOG_YYYYMMDD Currently i want to sequentially execute the same QUERY against all those tables. I wrote the PL/SQL below, but got stuck at line 10.

• Design ideas for a versioned db schema with related tables also versioned

  - by vfilby

  Here is the drill, I want to version a database. I have done this before using multiple rows where the table primary key becomes a combination of the row id and either a datestamp or a version #. Now I want to version a table that depends on many other small tables. Versioning each table will be a giant PITA, so I am looking for good options to verion a schema where the data to be versioned spreads over multiple tables. All related tables are properly keyed with foreign key relationships. The database is currently on Sql Server 2005.

• SQL: Join Parent - Child tables

  - by pray4Mojo

  I'm building a simple review website application and need some help with SQL Query. There are 3 tables (Topics, Comments, Users). I need a SQL query to select the data from all 3 tables. The 'Topics' table is the parent and the 'Comments' table contains the child records (anywhere from zero to 100 records per parent. The third table 'Users' contains the user information for all users. Here are the fields for the 3 tables: Topics (topicID, strTopic, userID) Comments (commentID, topicID, strComment, userID) Users (userID, userName) I tried: SELECT * FROM Topics Inner Join Comments ON Topics.topicID = Comments.topicID Inner Join Users ON Topics.userID = Users.userID But this does not work correctly because there are multiple topics and the User info is not joined to the Comments table. Any help would be appreciated.

• 600 tables in DDBB

  - by Michael

  Hi all, I'm a very young software architect. Now I'm working in a very large and I have to lead a group of developers to rewrite all the mortgage system of the bank. I'm looking at database tables and I realize that there is no any data model, neither documentation. The worst part is that there are about 1000 tables in dev environment, and like 600 in production. I trust more the production environment, but anyway, what can I do? I mean, I can suicide me or something, but is there any good reverse engineering tool, so at least I could get the schema definition with the relations between tables and comments extracted from the fields? Can you advice me something? Thanks in advance.

• Subsonic : Same column name different tables

  - by John Transformer

  Hi, I have a query where I need to do a "Where" clause for two different columns in two different tables but subsonic creates the same parametrized parameter name for both which is causing an issue. How can I fix this? string _RawSql = new Select() .From(Tables.Table1) .InnerJoin(Tables.Table2) .InnerJoin(Table3.SidColumn, Table2.Table3SidColumn) .Where(Table1.SidColumn).IsEqualTo(2) .And(Table3.SidColumn).IsEqualTo(1) .BuildSqlStatement(); The query this is creating is SELECT .... FROM [dbo].[Table1] INNER JOIN [dbo].[Table2] ON [dbo].[Table1].[Table2Sid] = [dbo].[Table2].[Sid] INNER JOIN [dbo].[Table3] ON [dbo].[Table2].[Table3Sid] = [dbo].[Table3].[Sid] WHERE [dbo].[Table1].[Sid] = @Sid AND [dbo].[Table3].[Sid] = @Sid Note that in the last two lines its using @Sid for both Table1 and Table3. How go I do it so it uses @Sid0 and @Sid1? Any help would be appreciated. Thanks

• Entity Framework 4 Hiding Underlying Resolver Tables when model is generated from database

  - by grrrrrrrrrrrrr

  When creating an entity framework model from scratch it is possible to specify a Many to Many relationship in the model. e.g Entity1 * ----- * Entity2 When a database is then generated from this, a resolver table is then created automatically between the two entities, this is hidden in the code model, allowing direct access to each of the entities via properties. e.g. Entity1 ----* ResolverEntity *----- Entity2 My question is, when a model is generated from an existing database, which contains resolver tables, is it possible to create the same effect so the resolver tables do not appear in the generated object model? When I have attempted this, the entity framework appears to create entities in the model for the resolver tables with no obvious way of hiding them in the object model. Thanks.

• MySQL Federated Tables Escaped Table Names

  - by Gordon

  I am trying to use MySQL federated tables. The problem is that the documentation specified at http://dev.mysql.com/doc/refman/5.0/en/federated-use.html says that a federated table should be created using the following format for the CONNECTION parameter: scheme://user_name[:password]@host_name[:port_num]/db_name/tbl_name E.G. CONNECTION='mysql://username:password@hostname:port/database/tablename' CONNECTION='mysql://username@hostname/database/tablename' CONNECTION='mysql://username:password@hostname/database/tablename' The problem is that the table I am trying to connect to has non-standard characters in it and I cannot find the proper way to scape them in the connections tring. For example, a table named `Table (one)` . Which has the space and the parenthesis, requiring backticks surrounding it inside any SQL code. Anyone know the proper way to do this?

• What's the difference between a Table and a Named Range in Excel 2007?

  - by technomalogical

  Can someone explain the difference between Tables and Named Ranges in Excel 2007? It seems that in addition to having the features of Named Ranges, they're somehow marked as Tables which gives them special formatting & filtering options in the ribbon. Other questions: Can I treat a table as a named range? Does a named range provide me any functionality not offered by a table, and vice versa? Should I use one over the other (assuming that consumers of the spreadsheet are using Excel 2007 or higher)? Google has not been helpful (excel difference between named range and table and excel 2007 difference between named range and table) and I've found one resource describing table functionality, but no reference to named ranges.

• How to change the placement of the left border of tables in Word

  - by mkva

  Hallo everybody I have the following problem: in MS Word, the left-side (and also the right-side) border is not aligned with the rest of the text on a page. It's actually the text in the first column of a table that is aligned with the text outside the table. And the table border is a little bit to the left. I find this layout quite a bit annoying, as I don't want to have any elements on a page outside the range that is used by normal text. Now my question: is it possible to have tables in Word such that the border lines align with the text outside the table? Thanks, Markus

• Changing the placement of the left border of tables in Word

  - by mkva

  Is it possible to have tables in Word such that the border lines align with the text outside the table? In MS Word, the left-side (and also the right-side) border is by default not aligned with the rest of the text on a page. It's actually the text in the first column of a table that is aligned with the text outside the table. And the table border is a little bit to the left. I find this layout quite a bit annoying, as I don't want to have any elements on a page outside the range that is used by normal text. I know that I can change the column delimiters manually (via the ruler). I'm looking for some more automatic way like setting the defaults for the whole document or such.

• Excel 2007 Pivot Tables: Overlapping issue hampers my summary sheet

  - by Mike

  I've created a Workbook that has 5 Pivot Tables (PT). I want to make a summary sheet that holds all these PT's, but when they expand the 'not allowed to overlap issue' causes me updating problems - they don't update/expand effectively. Therefore, can't be printed off easily. The sheet would basically help my users give their bosses a simple quick overview of the larger worksheet - this way they would be more inclined to fill it in (give a little too get a little philosophy). I had thought about using the Camera Tool, but I'm not sure how you could make it dynamic, or whether it can be dynamic with a PT? Any advice, links or step-by-steps are greatly appreciated. Thanks Mike.

• Excel Pivot Tables -- Divide Numerical Column Data into Ranges

  - by ktm5124

  Hi, I have an Excel spreadsheet with a column called "Time Elapsed" that stores the number of days it took to complete a task. I would like to make a pivot table out of this spreadsheet where I divide the "Time Elapsed" column into ranges, e.g., how many tasks took 0 to 4 days to complete how many tasks took 5 to 9 days how many took 10 to 14 days how many took 15+ days Do I have to create new columns in my spreadsheet dedicated to each interval (0 to 4, 5 to 9, etc.) or can I use some feature of pivot tables to separate my one "Time Elapsed" column into intervals? Thanks in advance.

• how're routing tables populated?

  - by Robbie Mckennie

  i've been reading "tcp/ip illustrated" and i started reading about ip forwarding. all about how you can receive a datagram and work out where to send it next based on the desination ip and your routing table. but what confused me is how (in a home network setting) the table itself is populated. is there a lower layer protocol at work here? does it come along with dhcp? or is it simply based on the ip address and netmask of each interface? i do know (from other books) that in the early days of ethernet one had to set up routing tables by hand, but i know i didn't do that.

• Corrupt mysql system tables

  - by psynnott

  I am having issues with the columns_priv table in the mysql system database. I cannot add new users currently. I have tried repairing it using mysqlcheck --auto-repair --all-databases --password but I get the following output: mysql.columns_priv Error : Incorrect file format 'columns_priv' error : Corrupt Is there any other way to repair this table, or how do I go about replacing it with a blank table? What would I lose by doing that? Thank you Edit (Additional Info) mysqld is currently using 100% cpu constantly.

• Can't type text into table cell when form is protected in Word 2002

  - by Gus

  I created several tables in an Word 2002 document to act as a form for users to fill out. In some cells I added check boxes and dropdown lists for people to select options from. When I click on the Protect form button the check boxes and dropdowns become active; however, I can't type anything in the other cells. If I click in an empty cell it automatically moves to the next checkbox. When I unprotect the form then I can type in the empty cells but then checkboxes and dropdowns become useless. I know that the user can double click on the checkbox and then manually select to have it checked, but they can't do this with the dropdowns. What do I have to do to allow the user to type in responses to the tables cells and also select answers from checkboxes and dropdowns? Thanks!

• Record Matching Software to Compare two tables and match on % Based

  - by Crazyd

  So I have some table with Name, Address, and Zip with no record data attached; and I have a table which has all the same, but has more information and I need a way to merge the tables when they don't match 100%. How do I match them up if they aren't Identical? I'm a newb @ SQL, but I know they won't match up for the most part and I can't be the only one with this issue. However software which will do this has proven to be difficult. Writing software to do this would even be worse than having to do it in the first place. I know I can do this in excel; kinda, but with the amount of records I have its proving to be difficult over a million.

• What can tables do that CSS positioning cannot?

  - by Jeremy Lew

  I know there are various good arguments preferring css positioning over table-based layouts. What I'm wondering is whether the CSS model is complete (assuming a relatively modern browser) with respect to ALL of the capabilities of tables. Are there layouts that tables can achieve that are impossible or impractical with CSS?
