  • Hibernate (JPA) Entity with Static collection as a member

    - by Kyle Partridge
    Is it possible to have a static collection as a member of a hibernate entity? Say I have an object Question: public class Question { private String category; ... } Would it be possible to populate a static Set<String> that is a distinct set of all categories in the Database? I know I could just query this, but I was wondering if there was a more elegant solution, as it seems like something that other people may have come across.

  • difference between where and nested queries

    - by Chris H
    I'm not able to figure out the difference between these queries. I'm pretty sure that the first one is an equi-join. I'm not sure how the second one ISN'T the same as the first. The sub query in #2 selects all Ids from S, and then it returns all R's that also have those ID's, no? SELECT R.cname FROM R, S, WHERE R.Id = S.Id SELECT R.cname FROM R WHERE R.Id IN (SELECT S.Id FROM S)

  • "Ambiguous column name" error on one particular server

    - by jazbit
    This simple query throws the "Ambiguous column name TaskID" error on one db-server only. This is ridiculous. We tested this with the same database structure on different servers and different versions of ms sql (2005/2008), and it's only THIS particular client's server that throws the error. I'm actually frustrated. SELECT Tasks.TaskID FROM Tasks INNER JOIN TaskHelpers ON TaskHelpers.TaskID = Tasks.TaskID order by TaskID Yes, I know I can put "Tasks.TaskID" into the order by clause, but for some reasons I can't.

  • Check checkbox checked property using jQuery

    - by Prasad
    I need to check the checked property of a checkbox and perform an action based on the checked property using jQuery. For example, if the age checkbox is checked, then I need to show a textbox to enter age, else hide the textbox. But the following code returns false by default: if($('#isAgeSelected').attr('checked')) { $("#txtAge").show(); } else { $("#txtAge").hide(); } How do I successfully query the checked property?

  • SQL Server - Missing Indexes - What would use the index?

    - by BankZ
    I am using SQL Server 2008 and we are using the DMV's to find missing indexes. However, before I create the new index I am trying to figure out what proc/query is wanting that index. I want the most information I can get so I can make informed decision on my indexes. Sometimes the indexes SQL Server wants does not make sense to me. Does anyone know how I can figure out what wants it?

  • How to save a Stored Procedure ?

    - by Richard77
    Hello, I've been playing today with stored procedures. I'm stoned that I picked the basic of it up so easily. (I'll also try triggers very soon). Now, I'd like to know how to save my SPROC under the stored procedure folder (Programmability - Stored Procedure) so that I can access it by name (eventually from my C# application). So far, when I press the save icon, I'm proposed to save the whole query. That's not what I want. Thanks for helping
