问题 Setup Using SQL Server 2008 R2. I have an ODBC call to a stored procedure that should time out after 3 seconds by using the SQLSetStmtAttr function with the SQL_ATTR_QUERY_TIMEOUT parameter. SQLSetStmtAttr( command, SQL_ATTR_QUERY_TIMEOUT, (SQLPOINTER)&timeOut, NULL ); Test I set a delay in the stored procedure for 15 seconds. The stored proc does indeed take just over 15 seconds to return. WAITFOR DELAY '00:00:15' Issue The problem is that the stored procedure returns correctly, where I am

问题 I have the following table Location Type Date A TestType 10-10-2013 A TestType 05-05-2013 A BestType 06-06-2013 B TestType 09-09-2013 B TestType 01-01-2013 I want to return the max date for each location regardless of the type but I must return all 3 columns. Desired result: Location Type Date A TestType 10-10-2013 B TestType 09-09-2013 What would be the best way to do this? I've looked into using RANK() Over Partition , but can't get it to work properly. 回答1: Using row_number() function and

问题 I have a stored procedure which realizes a pivot table. My Select statement was defined in a variable @query . Here is the code: BEGIN SET NOCOUNT ON; DECLARE @colNo nvarchar(max) DECLARE @query nvarchar(max) SET NOCOUNT ON; WITH vals AS ( SELECT DISTINCT t.No FROM QR_Tests t ) SELECT @colNo = COALESCE(@colNo + ', ', '') + '['+ No +']' FROM vals ORDER BY No SET @query = 'SELECT * FROM ( SELECT CASE WHEN GROUPING(No) = 0 THEN CAST(No as CHAR(12)) ELSE [ALL] END As No, CASE WHEN GROUPING(quote)

问题 In SSIS 2008, is there is way to design an SSIS package around the problem when an OLE DB data source returns an error like this "Database [xyz] cannot be opened. It is in the middle of restore."? I am hoping there is a way to design a loop into an SSIS 2008 package to trap this error, maybe wait 5 or 10 minutes for the source DB to finish restoring (from log shipping for example) and then try again - with a max retry limit built in. Thank You. 回答1: Yes. When you connect, don't connect to

问题 I have been using this connection string with no problem on a number of databases and MS operating systems. Windows Server 2003, 2008 R2 and 2012 R2 Eval, all Express versions. I am now trying to deploy to a new Windows Server 2012 R2 installation and I am getting some errors. I have the SQL Server 2008 R2 installation on the Windows Server 2012 R2 machine. My con string: connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\myDB.mdf;Integrated Security=True;User

问题 It seems like it's only possible to use a pass-through query to retrieve data from your SQL Server tables and into MS Access. But how about the other way? From an Access table to a SQL server table. What are my options from within MS Access when I need high performance? (The normal approach of having an append query that appends to a linked table is simply too slow ) In an pass-through query I cannot reference MS Access tables or queries, and therefore my INSERT INTO statement cannot work. Is

问题 I'm trying to count all the items for each brand and concatenate the brand name + number of items. I have this query in SQL Server 2008 R2: SELECT DISTINCT Brands.BrandName + ' ' + COUNT(Items.ITEMNO) as ITEMSNO, Brands.BrandId FROM Items, Brand_Products, Brands WHERE Items.ITEMNO=Brand_Products.ItemNo AND Brands.BrandId=Brand_Products.BrandId AND Items.SubcategoryID='SCat-020' GROUP BY Brands.BrandId, Brands.BrandName, Items.ITEMNO I'm trying to concatenate 2 fields, but I have 2 problems:

问题 When I execute this simple SP and then check for the query plan from the DMV query that follows, the query plan comes back as NULL. But if I comment out the else block in the SP (or change it to not reference temp table), the DMV query does show a query plan. Any idea what is causing this difference? And does a NULL query plan mean that nothing was cached? I'm using SQL Server 2008 R2. CREATE PROCEDURE dbo.SampleSp ( @Option TINYINT ) AS DECLARE @RowCount INT; -- Get ID into local temp table

问题 I've been looking all over for an answer to this, but nothing is explicit so hopefully someone knows off the top of their head. When using EXECUTE with a VARCHAR(MAX) variable, is there a character limit? I've done some experimenting and it seems that when load a variable and then call EXECUTE @var , there is a character limit on what is actually passed through to the server. When calling EXECUTE without the variable and just building the string there, everything appears to work.... is there
