Stored procedure: temp table created in procedure not visible

[zachmu]

Temporary tables created during stored procedure execution are not visible in the session in later statements.

Repro:

DROP PROCEDURE IF EXISTS CreateTemporaryTable;
DELIMITER //
CREATE PROCEDURE CreateTemporaryTable()
BEGIN
  DROP TEMPORARY TABLE IF EXISTS TEMP_TABLE;
  CREATE TEMPORARY TABLE TEMP_TABLE (NAME TEXT);
  INSERT INTO TEMP_TABLE VALUES ('A'),('B');

  SELECT * FROM TEMP_TABLE;
END //
DELIMITER ;

CALL CreateTemporaryTable();

Related bug: DROP TEMPORARY TABLE does not parse correctly.
