• Doctrine Join DQL

  - by koko

  I's like to do a join between 2 tables on a specific ID. At the moment, I have this DQL: $q = Doctrine_Query::create() ->select('e.*, i.itemName, i.itemtypeId') ->from('Model_EventItem e') ->leftJoin('Model_Item i ON e.itemId = i.itemId') ->where('e.eventitemId = ?', $event->eventId) ->orderBy('i.itemName ASC'); The result is empty, although my eventId has a value ...

• Large ResultSet on postgresql query

  - by tuler

  I'm running a query against a table in a postgresql database. The database is on a remote machine. The table has around 30 sub-tables using postgresql partitioning capability. The query will return a large result set, something around 1.8 million rows. In my code I use spring jdbc support, method JdbcTemplate.query, but my RowCallbackHandler is not being called. My best guess is that the postgresql jdbc driver (I use version 8.3-603.jdbc4) is accumulating the result in memory before calling my code. I thought the fetchSize configuration could control this, but I tried it and nothing changes. I did this as postgresql manual recomended. This query worked fine when I used Oracle XE. But I'm trying to migrate to postgresql because of the partitioning feature, which is not available in Oracle XE. My environment: Postgresql 8.3 Windows Server 2008 Enterprise 64-bit JRE 1.6 64-bit Spring 2.5.6 Postgresql JDBC Driver 8.3-603

• Problems with sp_addlinkedserver in MSSQL 2000

  - by manneorama

  Hi! I'm having a bit of a problem with moving specific data from one server running MSSQL 2000 (A) and another running MSSQL 2008 (B). I'm writing a script according to customer specifications which is to be executed on A, populating tables in B with data. However, I can't seem to get the server link to work. -- Bunch of declarations here EXEC sp_addlinkedserver @server = @ServerName, @srvproduct = @ServerProduct, @provider = @ProviderString, @datasrc = @RemoteHost -- Data migration stuff here EXEC sp_dropserver @ServerName Now if I run the script in its entirety I get an error saying: Msg 7202, Level 11, State 2, Line 55 Could not find server 'remoteServer' in sysservers. Execute sp_addlinkedserver to add the server to sysservers. However, if I higlight only the sp_addlinkedserver-part and execute that, there is no error and I can highlight the rest of the script and run it. What am I missing here? Please help! PS. If backup-restore was an option, I would have done that already.

• Finding nth-child of siblings via jQuery

  - by DA

  Let's say I have two tables that look like this: TH TH TH TH TD TD TD TD TD TD TD TD and TH TH TH TH TH TD TD TD TH TD TD TD I'd like to select the 3rd column in each. At first I was using nth-child as such: $('table tr td:nth-child(3)') But that's not going to work, as 3rd TD is in a different column in each table. What I need in pseudo code is 'get the 3rd TD or TH in each row'. I assume I need to use $.siblings but not entirely sure.

• Dynamic table design (common lookup table), need a nice query to get the values

  - by Swoosh

  sql2005 This is my simplified example: (in reality there are 40+ tables in here, I only showed 2) I got a table called tb_modules, with 3 columns (id, description, tablename as varchar): 1, UserType, tb_usertype 2, Religion, tb_religion (Last column is actually the name of a different table) I got an other table that looks like this: tb_value (columns:id, tb_modules_ID, usertype_OR_religion_ID) values: 1111, 1, 45 1112, 1, 55 1113, 2, 123 1114, 2, 234 so, I mean 45, 55, 123, 234 are usertype OR religion ID's (45, 55 usertype, 123, 234 religion ID`s) Don't judge, I didn't design the database Question How can I make a select, showing * from tb_value, plus one column That one column would be TITLE from the tb_usertype or RELIGIONNAME from the tb_religion table I would like to make a general thing. Was thinking initially about maybe a SQL function that returns a string, but I think I would need dynamic SQL, which is not ok in a function. Anyone a better idea ?

• Hibernate or JPA or JDBC or ???

  - by Yatendra Goel

  I am developing a Java Desktop Application but have some confusions in choosing a technology for my persistence layer. Till now, I have been using JDBC for DB operations. Now, Recently I learnt Hibernate and JPA but still I am a novice on these technologies. Now my question is What to use for my Java Desktop Application from the following? JPA Hibernate JDBC DAO any other suggestion from you... I know that there is no best choice from them and it totally depends on the complexity and the requeirements of the project so below are the requirements of my project It's not a complex application. It contains only 5 tables (and 5 entities) I wan't to make my code flexible so that I can change the database later easily The size of the application should remain as small as possible as I will have to distribute it to my clients through internet. It must be free to use in commercial development and distribution.

• Data Modeling Help - Do I add another table, change existing table's usage, or something else?

  - by StackOverflowNewbie

  Assume I have the following tables and relationships: Person - Id (PK) - Name A Person can have 0 or more pets: Pet - Id (PK) - PersonId (FK) - Name A person can have 0 or more attributes (e.g. age, height, weight): PersonAttribute _ Id (PK) - PersonId (FK) - Name - Value PROBLEM: I need to represent pet attributes, too. As it turns out, these pet attributes are, in most cases, identical to the attributes of a person (e.g. a pet can have an age, height, and weight too). How do I represent pet attributes? Do I create a PetAttribute table? PetAttribute Id (PK) PetId (FK) Name Value Do I change PersonAttribute to GenericAttribute and have 2 foreign keys in it - one connecting to Person, the other connecting to Pet? GenericAttribute Id (PK) PersonId (FK) PetId (FK) Name Value NOTE: if PersonId is set, then PetId is not set. If PetId is set, PersonId is not set. Do something else?

• username and password check linq query in c#

  - by b0x0rz

  this linq query var users = from u in context.Users where u.UserEMailAdresses.Any(e1 => e1.EMailAddress == userEMail) && u.UserPasswords.Any(e2 => e2.PasswordSaltedHash == passwordSaltedHash) select u; return users.Count(); returns: 1 even when there is nothing in password table. how come? what i am trying to do is get the values of email and passwordHash from two separate tables (UserEMailAddresses and UserPasswords) linked via foreign keys to the third table (Users). it should be simple - checking if email and password mach from form to database. but it is not working for me. i get 1 (for count) even when there are NO entries in the UserPasswords table. is the linq query above completely wrong, or...?

• Attributed strings in UITableViewCells without WebView?

  - by arnekolja

  Hello, does anyone know if there's a way in with 3.0+ to display attributed strings within a UITableViewCell without using a UIWebView for that? I need to display a string with linked, tappable substrings as the typical detailTextLabel. I wouldn't mind exchanging this UILabel against another type of view, but I think a UIWebView could be just too slow when rendering a table with hundrets of cells. Or does someone have opposite experiences here? So my question is: what's the best way to achieve mixed strings in a very large table without a great performance hit? I searched for this almost a whole day now, but I can only find old posts mentioning that there's no attributed string on the iPhone (outdated, as this was pre-3.0) and/or saying that they use a UIWebView for that. But really, I don't think this would perform very well on large tables, would it? Many, many thanks in advance Arne

• Can an Excel VBA UDF called from the worksheet ever be passed an instance of any Excel VBA object mo

  - by jtolle

  I'm 99% sure that the answer is "no", but I'm wondering if someone who is 100% sure can say so. Consider a VBA UDF: Public Function f(x) End Function When you call this from the worksheet, 'x' will be a number, string, boolean, error, array, or object of type 'Range'. Can it ever be, say, an instance of 'Chart', 'ListObject', or any other Excel-VBA object model class? (The question arose from me moving to Excel 2007 and playing with Tables, and wondering if I could write UDFs that accept them as parameters instead of Ranges. The answer to that seems to be no, but then I realized I didn't know for sure in general.)

• T-SQL error object exists when separated in if/else blocks

  - by Jeff O

  I get the error: Msg 2714, Level 16, State 1, Line 16 There is already an object named '#mytemptable' in the database. There are ways around it, but wonder why this happens. Seems like SQL Server is verifying both blocks of the if/else statement? declare @choice int select @choice = 1 if @choice = 1 begin select 'MyValue = 1' AS Pick into #my_temp_table end else begin select 'MyValue <> 1' AS Pick into #my_temp_table end select * from #temptable drop table #temptable If the tables have different names, it works. Or if I create the temp table and use Insert Into... statements that works as well.

• Is a .Net membership database portable, or are accounts somehow bound to the originating Web site or

  - by Deane

  I have an ASP.Net Web site using .Net Membership with a SQL Server provider, so the users and roles are stored in the SQL tables created by Aspnet_regsql.exe. Is this architecture totally self-contained and portable, or are users in it somehow bound to the specific Web site on which they create their account? Put another way, if we create a bunch of users in dev or UAT, the back up and restore this database to another server, accessed under another domain name, should it still work just fine? We're seeing some odd behavior when we move the database, like users losing group affiliation and such, and I'm curious how portable and environment-agnostic this database really is. I have a sneaking suspicion that something is bound to the machine key or the domain.

• Securing Plugin Data in WordPress From Access by Other Plugins?

  - by farinspace

  There probably is some solution to this, whether it involves code running on just the wordpress installation or a combination of a wordpress installation and a master server I am not sure yet, but please remember not to have tunnel vision and consider any and all possible solutions: The scenario is this: A WordPress plugin (plugin-A) that manages some sort of valuable data (something that the admin would not want stolen), lets say, lead data with user's name and email addresses, the plugin uses its own db tables. Other than the obvious (which is the admin installing plugin-B, not knowing its malicious intent), what is to prevent another WordPress plugin (plugin-B) from accessing plugin-A data or hacking plugin-A files to circumvent security.

• What's the fastest way to check the availability of a SQL Server server?

  - by mwolfe02

  I have an MS Access program in use in multiple locations. It connects to MS SQL Server tables, but the server name is different in each location. I am looking for the fastest way to test for the existence of a server. The code I am currently using looks like this: ShellWait "sc \\" & ServerName & " qdescription MSSQLSERVER > " & Qt(fn) FNum = FreeFile() Open fn For Input As #FNum Line Input #FNum, Result Close #FNum Kill fn If InStr(Result, "SUCCESS") Then ... ShellWait: executes a shell command and waits for it to finish Qt: wraps a string in double quotes fn: temporary filename variable I run the above code against a list of server names (of which only one is normally available). The code takes about one second if the server is available and takes about 8 seconds for each server that is unavailable. I'd like to get both of these lower, if possible, but especially the fail case as this one happens most often.

• aspnet_regsql not working at all

  - by user252160

  I would like to create the ASP.NET User database template on a database of my own, because I'd like to fully untegrate the user system with the rest of my DB. As I've read, i needed to use the aspnet_regsql tool. I put all the options (because my database is running on SQLEXPRESS and is in an mdf file in my project's folder). the program starts and seemingly runs without any errors, however, when I open the database after that, not tables or stored procedures have been added. One more thing: I did one more test. I intentionally gave the -d option a wrong mdf file address, and surprisingly, the program "finished" correctly, yet no file was crated or modified whatsoever.

• How to pass parameters to report model in Reporting Services

  - by savras

  I'm developing report in RS that show top N customers based on some criteria. It also allows to select number of customers and period of time. Is it possible to do it by using report model? Thing that it seems to be difficult is how to pass parameters determined by user. Another thing that in my oppinion is very disappointing is that i cannot use SQL query as dataset query, because it uses odd and elaborate XML. Although report model items seem to map its fields to query or table fields. I m concerning using report models because i need to provide uniform data model (the same tables and fields) for more or less different database schemas. It would be very nice if somebody would explain what can be done with report models and what can not.

• End User Ad-Hoc Reporting Tool: Microsoft SQL Server Management Studio or Microsoft Access?

  - by schultkl

  Our centralized IT department has suggested two primary ad hoc query tools for our general user base of approximately 200 staff members: Microsoft SQL Server Management Studio 2008 (SSMS) Microsoft Access 2003 Environment The backend database is a read-only Microsoft SQL Server 2005 database. The schema is 400+ tables; allowing access to the raw data for our general staff would be a disaster. We will be building an "abstraction layer" over the raw data for our general staff to run ad hoc queries against. The abstraction layer will most likely contain a number of views. A number of users have basic knowledge in Microsoft Access; none have used SSMS. Which of the above tools (or alternative) would be best for a decidedly non-techie user base of approximately 200 people? What are the pros and cons of each? Also, the IT department has suggested teaching people T-SQL so they may use SSMS. Is this reasonable?

• Java - JDBC alternatives

  - by Mike

  Hello, this is just teorethical question. I use JDBC with my Java applications for using database (select, insert, update, delete or whatever). I make "manually" Java classes which will contain data from DB tables (attribute = db column). Than I make querys (ResultSet) and fill those classes with data. I am not sure, if this is the right way. But I've read lot of about JDO and another persistence solutions. Can you please recommend some? Which are modern? Will be used in the future? Some advantages of JDO over JDBC (in simple words). I've been able to google lot of this stuff, but opinions from the "first hand" are always best. Thank you for responses, Mike

• Programming languages & proof of concepts

  - by Mike

  There are plenty of programming languages out there, as you all may know. I am primarily looking for a list of programming languages WITH some very neat proof of concepts. I would really like to learn a new language, but whenever I dive into something new and popular, it isn't what I expected. Any tutorial out there will give you code, small examples, but won't show you the true power of the language. I am looking for examples that run entirely on the language that it is exemplifying. For example, If I said C#, I could possibly show you a complete C# app with backend queries, reports, tables, all with a nice interface. It would be completely reliant on the language that is provided, so no supporting languages. I understand that most languages are integrated with other languages in order to provide a richer application. Any links, charts, websites that may reflect this request is appreciated.

• Major performance difference between two Oracle database instances

  - by jrdioko

  I am working with two instances of an Oracle database, call them one and two. two is running on better hardware (hard disk, memory, CPU) than one, and two is one minor version behind one in terms of Oracle version (both are 11g). Both have the exact same table table_name with exactly the same indexes defined. I load 500,000 identical rows into table_name on both instances. I then run, on both instances: delete from table_name; This command takes 30 seconds to complete on one and 40 minutes to complete on two. Doing INSERTs and UPDATEs on the two tables has similar performance differences. Does anyone have any suggestions on what could have such a drastic impact on performance between the two databases?

• Hierarchical data table for JSF2 and RichFaces

  - by Iravanchi

  I'm using RichFaces on my JSF2 application, and I need a way to have something like a tree-column or tree-table. As far as I know, there's no support for such thing in RichFaces. Something's mentioned for RichFaces 4.0, but the priority of this in their plan isn't promising at all, and I don't think that it's going to be included in 4.0. I know there's a tree table available in IceFaces, but I'd rather not add another library to avoid conflicts and learning curve and ... So, I'm looking for the simplest way that I can achieve the same results with minimum efforts, maybe using sub-tables in RichFaces? Any ideas would be appreciated.
