Question

Can anyone tell how correct the following code below. Iam tryin to create a stored procedure that returns the rowcount of a table whose name is passed to it.

CREATE PROCEDURE spROWCOUNTER (     @tablename nvarchar(20)     @rowCountVal int OUTPUT )  AS  DECLARE @strQuery nvarchar(300)  SET @strQuery = 'SELECT @rowCountVal=COUNT(*) FROM '+@tablename  EXEC(@strQuery)  RETURN @rowCountVal 

ERROR MESSAGE :

• Incorrect syntax near ‘@rowCountVal’
• Must declare scalar variable ‘@tablename’
• Must declare scalar variable ‘@rowCountVal’

---

whereas the code below works fine

ALTER PROCEDURE spROWCOUNTER (     @rowCountVal int OUTPUT )  AS  SELECT @rowCountVal=COUNT(*) FROM DEFECT_LOG  RETURN @rowCountVal 

Answer 1

CREATE PROCEDURE spROWCOUNTER        @tablename nvarchar(20),         @rowCountVal int OUTPUT AS  SELECT @rowCountVal = ISNULL(SUM(spart.rows), 0) FROM sys.partitions spart  WHERE spart.object_id = object_id(@tablename) AND spart.index_id < 2  RETURN @rowCountVal
