Problem with sp_executesql
My query runs clean however, it does absolutely nothing when using sp_executesql. When I run it without using sp_executesql it works fine, but I need sp_executesql to pass in different db names. When I run the query, no rows are updated and when I print my @SQLString variable it doesn't return anything at all. In looking through the server trace in QA everything is being set and executed like it should be... Any ideas? (Sorry for the voluminous code)
DECLARE @Id int, @Name varchar(100) Set @id = 5 Set @Name = 'Shire' Declare @SQLString nvarchar (4000) DECLARE @IDAsChar nvarchar(100) SET @SQLString = N'create table #objects (objectID int, dbID smallint) insert into #objects (ObjectID, dbID) select distinct o.id, ucv.dbID from [[[Benditt.][' + @Name + '].][dbo].]sysobjects o join [[[Benditt.][' + @Name + '].][dbo].]syscomments c (nolock) on o.id = c.id left outer join UWCustom.dbo.UW_Code_Versions ucv (nolock) on o.id = ucv.objectId and o.xtype = ucv.xtype and u.name = ucv.OwnerName and "' + @Name + '" = ucv.dbName and o.name = ucv.ObjectName and c.colid = ucv.colid and ' + @IDAsChar + '= ucv.dbID and LastVersion = "Y" where o.xtype in ("P", "V") and checksum(c.text) <> ucv.TextCheckSum update UWCustom.dbo.uw_code_versions set LastVersion = "N" where ObjectID IN (select ObjectID from #Objects) and dbID = ' + @IDAsChar + ' Insert into UWCustom.dbo.UW_Code_versions ( ObjectID , xtype , dbName , dbID , Ownername , ObjectName , colid , DateEntered , TextCheckSum , text ) select o.id , o.xtype , ' + @Name + ' , ' + @IDAsChar + ' , u.name , o.name , c.colid , getdate() , checksum(c.text) , c.text from #objects join [[[Benditt.][' + @Name + '].][dbo].]sysobjects o (nolock) on #Objects.ObjectID = o.id join [[[Benditt.][' + @Name + '].][dbo].]syscomments c (nolock) on o.id = c.id join [[[Benditt.][' + @Name + '].][dbo].]sysusers u (nolock) on o.uid = u.uid drop table #Objects' PRINT @SQLString EXEC sp_executesql @SQLString GO |

Hi,
Your problem is that you are declaring : DECLARE @IDAsChar nvarchar(100) but then not setting anything to it, it is defaulting to NULL which then means that when you try to join a 'NULL' to any other text : and ' + @IDAsChar + '= ucv.dbID You'll get a NULL returned when you try to print it. Hope this helps, Alaistair |
