Error Using Temporary Tables With Same Names SQL Server - sql

Question

Here is my scenario. (Following is my stored proc taking #date as an input parameter)
DECLARE #date DATE
If object_id('tempdb..#TempList') is not null drop table #TempList
go
Create table #TempList (MILL_NO VARCHAR(7), SHIP_DATE DATE, BL_STATUS NCHAR(1),
FOOTAGE DECIMAL(12,4))
If #date IS NULL
Insert into #TempList
Select mill_no, null, bl_status,footage from fn_A(0,0)
Select * from #TempList
If object_id('tempdb..#TempList') is not null drop table #TempList
go
Create Table #TempList (MILL_NO VARCHAR(7), SHIP_DATE DATE, BL_STATUS NCHAR(1),
FOOTAGE DECIMAL(12,4))
If #date IS NOT NULL
Insert into #TempList
Select * from fn_B(0,'06/06/2006')
Select * from #TempList
I figured out from one of the posts that I cannot use temporary tables with same names unless I inclide a GO. However, including GO is not taking the parameters I try to pass.
Is there an alternate approach to eliminate this error?

Answer 1

Based on the procedure supplied, you could use TRUNCATE TABLE instead.
I don't see a point dropping and recreating a table if all you want to do is quickly remove the records.
EDIT
You don't drop and recreate your table with the same name; instead of this code:
If object_id('tempdb..#TempList') is not null drop table #TempList go
Create Table #TempList (
MILL_NO VARCHAR(7),
SHIP_DATE DATE,
BL_STATUS NCHAR(1),
FOOTAGE DECIMAL(12,4)
)
Just do this:
TRUNCATE TABLE #TempList

Answer 2

if object_id('tempdb..#TempList') is allways NULL because #TempList is not the name that results created on tempdb's sysobjects table when you do create table #TempList
EDIT
what about this:
CREATE PROC PIRULO(#date as DATE) as
Create table #TempList (MILL_NO VARCHAR(7), SHIP_DATE DATE, BL_STATUS NCHAR(1), FOOTAGE DECIMAL(12,4))
IF #date IS NULL
Insert into #TempList
Select mill_no, null, bl_status,footage from fn_A(0,0)
ELSE
Insert into #TempList
Select * from fn_B(0,'2006/06/06') -- also I changed date order.
Select * from #TempList

Answer 3

I struggled all these days to insert values into same temporary table when a given condition is met.
Given that I am on a project migrating FoxPro(which has cursors declared all over) to SQL Server this small logic needed to be implemented in multiple stored procs.
Finally, what I learned out of this is - Think Straight Before Trying Anything Different (suggestion to my co-beginners in DB migration).
DECLARE #date DATE
SET #date = '06/06/2006' --#date = null
If object_id('tempdb..#TempList') is not null drop table #TempList
Create table #TempList (MILL_NO VARCHAR(7), SHIP_DATE DATE, BL_STATUS NCHAR(1),
FOOTAGE DECIMAL(12,4))
If #date = null
-- Here I am inserting null in place of Ship_Date because fn_A returns only 3 columns in my case
Insert into #TempList
Select mill_no, null, bl_status,footage from fn_A(0,0)
--Select * from #TempList
else
Insert into #TempList
Select * from fn_B(0,#date)
Select * from #TempList
Thanks everyone for giving your inputs. Hope this helps somebody.
