Table variable in Stored Procudure - sql-server

Question

Hi I have developed a stored procedure in which I declared the a table variable called #TEMP_TABLE but for this line
SET #SQL1 = 'UPDATE PO_STAGE set PO_STAGE.ISVALID = ''N''
FROM ERP_ADMIN.'+#STAGE_TABLE+' PO_STAGE, #TEMP_TABLE TMP
where PO_STAGE.ERP_PO_ID = TMP.ERP_POID'
exec (#SQL1)
I am getting "Must declare the table variable "#TEMP_TABLE"." error.
Please help me in this regards.Below is the code for Stored Procedure.
CREATE PROCEDURE [ERP_ADMIN].[VALIDATE_PURCHASE_ORDER]

Answer 1

You should pass #TEMP_TABLE as parameter. To pass Table parameter you should create table type at first:
IF NOT EXISTS (SELECT 1 FROM sys.types WHERE NAME = 'TEMP_TABLE_TYPE')
CREATE TYPE TEMP_TABLE_TYPE AS TABLE(
ERP_POID nvarchar(50),
ERRORCD nvarchar(50),
ERRORMSG nvarchar(120)
);
And use it:
exec sp_executesql #Sql, N'#TEMP_TABLE TEMP_TABLE_TYPE readonly', #TEMP_TABLE
For epxplonation you can use this link Passing table variable into dynamic sql.
If you find this way not obvious, I advise to use temporary table instead of table varible:
CREATE TABLE #TEMP_TABLE (
ERP_POID nvarchar(50),
ERRORCD nvarchar(50),
ERRORMSG nvarchar(120)
);
