Dynamic SQL Statements In A Stored Procedure

Hi

I have a small problem writing a stored procedure in a SQL Server 2000 database.

I would like to generate som part of the SQL inside this stored procedure that is used in an IN expression of my WHERE clause. There is no problem for me to generate a string containing my expression, the problem is that SQL-Server don´t generate a resulting SQL-statement.

Example:

CREATE PROCEDURE spDynStatement
AS

DECLARE @sPartOfSQLStatement NVARCHAR(100)

-- Some T-SQL that generates the dynamic part of the SQL-statement
-- .
-- .
-- .

-- As substitute I insert the string expression
SET @sPartOfSQLStatement = '''1''' + ', ' + '''1.5'''

-- SELECT @sPartOfSQLStatement results in: '1' , '1.5'

SELECT * FROM BBNOrganization WHERE OrgStructureID IN( @sPartOfSQLStatement ) -- does not work

SELECT * FROM BBNOrganization WHERE OrgStructureID IN( '1', '1.5' ) -- works!!!
GO

Thankfull for ideas on how to solve my problem,

Peter
