  • JDBC Code Change From SQL Server to Oracle

    - by BeginnerAmongBeginners
    In the JDBC code, I have the following that is working with SQL Server: CallableStatement stmt = connection.prepareCall("{ call getName() }"); ResultSet rs = stmt.executeQuery(); if(rs != null) { while(rs.next()) { //do something with rs.getString("name") } } Multiple rows are returned for the above situation. I understand that the use of a cursor is required to loop through the table in Oracle, but is there any way to keep the above code the same and accomplish the same thing? Thanks in advance.

  • Long time to load first sql connection in .NET

    - by Shrage Smilowitz
    For some reason it takes 7 seconds to open a connection to a sql server database for the firt time, subsequent connections takes a second. any idea what could be the reason? I'm using C# and asp.net Its after compilation, i essence every time i restart the site, which means every time it needs to actualy create the "first" connection. i understand that setting up connection pooling has overhead, but i have never seen that i should take 7 second to set it up.

  • SQL: HAVING clause

    - by Craig Johnston
    See the following SQL statement: SELECT datediff("d", MAX(invoice.date), Now) As Date_Diff, MAX(invoice.date) AS max_invoice_date, customer.number AS customer_number FROM invoice INNER JOIN customer ON invoice.customer_number = customer.number GROUP BY customer.number If the the following was added: HAVING datediff("d", MAX(invoice.date), Now) > 365 would this simply exclude rows with Date_Diff <= 365? What should be the effect of the HAVING clause here?

  • SQL swap field values

    - by Silence
    I have a SQL table (MYSQL 4.0 to be precise) composed of the following : int no (primary) int field1 int field2 I would like to swap the values of field1 with the values of field2 and vice-versa. Ex.: 1;2.5;3.76 becomes 1;3.76;2.5 I need a swapping temporary variable of some sort. But I don't think I can use something like Set @var1 = field1 inside my update statement. And I don't think altering the table to add a temporary column is my best best either.

  • Convert dependencies to point to View instead of Table

    - by jwarzech
    I currently have a SQL Server 2008 database in which I am planning to separate out some tables to other databases. I want to be able to replace all references to the separated tables from the original database using views. Is there a better way (other than manually changing all FK and SProc references) to switch all the dependencies to reference the view instead of the table?

    - by Andrei Tanasescu
    I am building a c# - linq - sql server winforms/asp.net application, accessing a database. I would like my business logic layer to be easily testable, and that means not littering it with Linq database queries everywhere. What design patterns/ best practices are available for the following use cases - inserting/updating a new object - searching for an object - loading a bunch of related data into a sort of "presentation" object that could be displayed by various views ?

  • T-SQL get SELECTed value of stored procedure

    - by David
    In T-SQL, this is allowed: DECLARE @SelectedValue int SELECT @SelectedValue = MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1 So, it's possible to get the value of a SELECT and stuff it in a variable (provided it's scalar, obviously). If I put the same select logic in a stored procedure: CREATE PROCEDURE GetMyInt AS SELECT MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1 Can I get the output of this stored procedure and stuff it in a variable? Something like: DECLARE @SelectedValue int SELECT @SelectedValue = EXEC GetMyInt (I know the syntax above is not allowed because I tried it!)
