This sp is fine and working Perfectly and i have a UDF defined like this

ALTER FUNCTION [dbo].[Concat] (@Name varchar(50),@Actv int)
RETURNS varchar(max)
WITH EXECUTE AS CALLER
AS
BEGIN
Declare @s varchar(max)
SET @s = ''
SELECT @s = @s + IsNull(',' + Cast(Cycletemplate AS varchar), '')
FROM #Temp (NOLOCK)
WHERE #Temp.Descr = @Name And Temp.Actv = @Actv
GROUP BY Cycletemplate
ORDER BY Cycletemplate
IF (@S IS NOT NULL) AND (@S <> '') SET @S = SubString(@s, 2, Len(@S)-1)
RETURN @S
END

now the UDF is used in the Bolded part of the Sp

i know i cant use a #temp table in a UDF , i want to access a temp table created in the Sp i want to use it in the UDF. i can use table Variables, but is there a Global table variable ? that i can use, that is created in the sp but used in the UDF. I need your Advice.

Thanks

One suggestion:

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[tempdb].[dbo].[#temp]'))

You can replace that with:

IF OBJECT_ID('tempdb..#Temp', 'U') IS NOT NULL DROP TABLE #Temp

Now on to your original question .. that is a lot of code. What are you trying to do exactly? And have you considered using permanent tables? You could create a "LoadMaster" table with an autoincrement column. When you start your sproc insert a value and retrieve the SCOPE_IDENTITY() . Then have child load tables from that with the proper table structure where you can insert your "LoadMasterId" then the other columns. Pass the "LoadMasterId" off to your processing logic so everything references permanent tables. It may also make debugging easier since you can go back and review the data.

Good Day sknake

Thanks for Pointing that out

IF OBJECT_ID('tempdb..#Temp', 'U') IS NOT NULL DROP TABLE #Temp

Before i used a Solid table , but now it becomes a Problem u in a multi user enviroment because some other users will receive the "temp table does not exist" or "temp table already exist" with #temp table it was going to be easy. but due to the fact that UDF does not like the #temp. Your Solution that you suggested will you please elaborate more deeply on it.

Thanks for you reply.

Its hard to give you an example since your queries are very complex but basically create a "Load" a set of Load tables matching your source table structure, with some additional columns.

Lets say I have a table called ExperimentReading that I want to do processing on in a `temporary` environment. Here is the original table:

CREATE TABLE [dbo].[ExperimentReading](
	[ExperimentReadingId] [int] IDENTITY(1000,1) NOT NULL PRIMARY KEY,
	[ExperimentId] [int] NULL,
	[ExperimentTubeId] [int] NULL,
	[ReadingTime] [int] NULL,
	[ReadingValue] [money] NULL
)

Now to set up the Load environment:

IF OBJECT_ID('LoadMaster', 'U') IS NOT NULL DROP TABLE LoadMaster
Create Table LoadMaster
(
  LoadMasterId int identity(1000, 1) PRIMARY KEY NONCLUSTERED,
  CreateDate DateTime,
  UserName varchar(20)
)
GO
IF OBJECT_ID('LoadExperimentReading', 'U') IS NOT NULL DROP TABLE LoadExperimentReading
Create Table LoadExperimentReading
(
    LoadExperimentReading int identity(1000, 1) PRIMARY KEY,
    LoadMasterId int NOT NULL,
  	--[ExperimentReadingId] [int] IDENTITY(1000,1) NOT NULL, Need to remove the identity attributes
  	ExperimentReadingId int NOT NULL,
	[ExperimentId] [int] NULL,
	[ExperimentTubeId] [int] NULL,
	[ReadingTime] [int] NULL,
	[ReadingValue] [money] NULL,
)
ALTER TABLE LoadExperimentReading ADD CONSTRAINT IX_LoadExperimentReading_Uniq_1 UNIQUE(LoadMasterId, ExperimentReadingId)

And how I would use these tables:

Declare @LoadMasterId int
INSERT INTO LoadMaster (CreateDate, UserName) Values (GetUtcDate(), 'Sknake')
Set @loadMasterId = CAST(SCOPE_IDENTITY() as int) --This is our load ID that we will reference

Insert Into LoadExperimentReading (LoadMasterId, ExperimentReadingId, [ExperimentId], [ExperimentTubeId], [ReadingTime], [ReadingValue])
Select 
@LoadMasterId, --Our load ID from the insert. Guarantees only the user who created it will access the data
CAST(ExperimentReadingId as int) As ExperimentReadingId, --Trims off the identity stuff from the source table
[ExperimentId], [ExperimentTubeId], [ReadingTime], [ReadingValue]
From [ExperimentReading]

It won't be a problem in a multi-user environment because when a user inserts a record to the LoadMaster table they are given a LoadMasterId. Insert all of the child/related records in to other load tables with the @ID pulled from the insert, and only reference those load records in your UDF/SP. You would change your existing logic to include a @LoadId int parameter.
