Hi,

I'm facing a problem and hope that can get some advise from you. I want to pass a filter query into store procedure.

For example,

SQL

alter proc [dbo].[SP_Staff]
     @Filter varchar(1000)=''
as
--drop tempTable if exist
if exists (select  * from tempdb.dbo.sysobjects o where o.xtype in ('U')
    and o.id = object_id(N'tempdb..#TmpTable')) 
DROP TABLE #TmpTable;
DECLARE @SQLQuery AS VARCHAR(1000)
DECLARE @SQLQuery1 AS VARCHAR(1000)

SET @SQLQuery = 'select * into TmpTable From Staff'
SET @SQLQuery1 = 'order by StaffCode'
IF Len(@Filter) > 0
Begin
SET @SQLQuery = @SQLQuery + ' Where ' + @Filter + @SQLQuery1
End
EXECUTE(@SQLQuery)
select * from #TmpTable

execute SP_Staff 'StaffCode between 001 and 005'

It got error "Invalid object name '#TmpTable'" when I execute the store procedure.
How to solve this error?

Hi frnd:

Basically it is unable to find temporary table #TmpTable
First of all i would like to know where you are creating #TmpTable table.

One another thing missing in the below line:

"HTML"

SET @SQLQuery = 'select * into TmpTable From Staff'

It should be like this :

"HTML"

SET @SQLQuery = 'select * into #TmpTable From Staff'

My suggestion is instead of using this code:

"HTML"

if exists (select  * from tempdb.dbo.sysobjects o where o.xtype in ('U')
    and o.id = object_id(N'tempdb..#TmpTable'))
DROP TABLE #TmpTable;

Modify the code like this :

SQL

if exists (select  * from tempdb.dbo.sysobjects o where o.xtype in ('U')
    and o.id = object_id(N'tempdb..#TmpTable'))
Begin
  DROP TABLE #TmpTable;
  Create Table #TmpTable(
   Id int --  you may include more columns (for Example)
  )
End

You don't need to remove the temp table in begining. It would anyways be removed after the SP execution.

Look at this:

SQL

alter proc [dbo].[SP_Staff]
     @Filter varchar(1000)=''
as

DECLARE @SQLQuery AS VARCHAR(1000)
DECLARE @SQLQuery1 AS VARCHAR(1000)

SET @SQLQuery = 'select * into #TmpTable From Staff'
SET @SQLQuery1 = 'order by StaffCode'
IF Len(@Filter) > 0
Begin
SET @SQLQuery = @SQLQuery + ' Where ' + @Filter + @SQLQuery1
End
EXECUTE(@SQLQuery)
select * from #TmpTable

DROP TABLE #TmpTable;

It should be like this

SQL

SET @SQLQuery = 'select * into #TmpTable From Staff'
SET @SQLQuery1 = 'order by StaffCode'

SQL

if (IsNull(OBJECT_ID('SP_Staff'),0) <> 0)
	Drop Procedure SP_Staff
Go
Create Procedure SP_Staff
	@rvcFilter	varchar(max)
As  
Begin

	Declare @vcQuery varchar(max)
	
	if (IsNull(OBJECT_ID('tempdb..##tempTable'),0) <> 0)
		Drop Table ##temp1234;
	
	if(Len(RTRIM(LTRIM(@rvcFilter))) = 0)
		Set @rvcFilter = '1 = 1';
	
	Set @vcQuery =
		'Select * into #tempTable From Staff'
		+ ' Where '
		+ @rvcFilter
		+ ' Order By StaffCode';
	
	Execute(@vcQuery)	

	Select * From ##tempTable

End
Go

EXECUTE  SP_Staff 'StaffCode between 001 and 005'
