Prepared statement needs to be re-prepared in mysql - mysql

Question

I'm trying to access data from view and insert into a temptable, inside a store procedure, below is the store procedure .
When I try to execute the sp I'm getting "Prepared statement needs to be re-prepared" error.
Can some one pls suggest how to fix this error in mysql.
Procedure:
DROP PROCEDURE IF EXISTS getFilteredData;
CREATE PROCEDURE getFilteredData()
BEGIN
DECLARE sql2 VARCHAR(5000);
DROP TEMPORARY TABLE IF EXISTS TempTbl;
CREATE TEMPORARY TABLE TempTbl
(
ID VARCHAR(50),
Name VARCHAR(500),
Status INT
);
SET sql2 = 'INSERT INTO TempTbl Select ID,Name,Id as Status from v_release;';
SET #SWV_Stmt = sql2;
PREPARE SWT_Stmt FROM #SWV_Stmt;
EXECUTE SWT_Stmt;
DEALLOCATE PREPARE SWT_Stmt;
SELECT * FROM TempTbl;
END;
