Affects: 5.3.27
I have the below procedure which I wanted to run before each test in my spring boot application integration tests to quickly truncate all tables in my schema:
DELIMITER //
CREATE PROCEDURE truncate_tables()
BEGIN
DECLARE tblName CHAR(200);
DECLARE done INT DEFAULT FALSE;
DECLARE dbTables CURSOR FOR
SELECT table_name
FROM information_schema.tables
WHERE table_schema = (SELECT DATABASE());
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;
OPEN dbTables;
SET FOREIGN_KEY_CHECKS = 0;
read_loop: LOOP
FETCH dbTables INTO tblName;
IF done THEN
LEAVE read_loop;
END IF;
SET @s = CONCAT('TRUNCATE TABLE ', tblName);
PREPARE stmt FROM @s;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
END LOOP read_loop;
CLOSE dbTables;
SET FOREIGN_KEY_CHECKS = 1;
END
//
CALL truncate_tables();
DROP PROCEDURE IF EXISTS truncate_tables;
This runs perfectly fine when I try to execute it on a local DB via MYSQL Workbench. But when I try to run the scripts before a test case in spring boot integration tests, it complains.
@Test
@Sql("classpath:sql/cleanup.sql")
@Sql("classpath:sql/some_other_script.sql")
public void testCase() {}
Error:

I have tried tuning several things in the procedure like changing the delimiter, closing statements with ; etc. All of the variations works fine on the DB directly via MySQL workbench but doesn't work when loaded with spring context.

It looks like you've created a question on SO already. Please do not cross-post, especially without saying you've done so.
blockCommentEndDelimiter looks like something MySQL specific so we won't be able to handle that. In general, our parser is ANSI-SQL and we can't handle all the subtleties of db-vendors. To make a fair comparison, running this a simple JDBC client would be better than doing that in MySQL workbench.
