MySQL, MyBatis, Grammar error - mysql

Question

I have an application using MyBatis, and I'm trying to add a select SQL that has multiple statements.
<select id="getReleaseDetails" resultType="maingrid" statementType="STATEMENT">
DROP TEMPORARY TABLE IF EXISTS vrTmp;
DROP TEMPORARY TABLE IF EXISTS vrTmp2;
CREATE TEMPORARY TABLE vrTmp AS (
SELECT vr.*, v.Code
...etc.
However, I keep getting the error:
Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'DROP TEMPORARY TABLE IF EXISTS vrTmp2;
CREATE TEMPORARY TABLE vrTmp AS (
S' at line 2
]

S' at line 2
The error may exist in mappings/mapping.xml
The SQL works fine in SQLYog, using the same database login.
What am I missing? It's almost like it does not like the ";" to separate the individual statements.
Thanks

Answer 1

Figured it out: by default the MySQL connection does not allow execution of multiple SQLs. It has to be specified in the URL:
url="jdbc:mysql://ln-ct-dv-my1:3306/TestDB?allowMultiQueries=true"
... and I had to remove the "StatementType" from the mapping file.

Here are some problems.
You can not use multiple statements in single tag in mybatis. Hence you can not use ";"
If at all if you want to use create table statement use insert tag.
The solution would be to use stored procedure to run multiple statements.
Here is an example for stored procedure and how to call it from mybatis.
CREATE OR REPLACE PROCEDURE KP_PRC AS
BEGIN
execute immediate 'DROP TEMPORARY TABLE IF EXISTS vrTmp';
execute immediate 'DROP TEMPORARY TABLE IF EXISTS vrTmp2';
execute immediate 'CREATE TEMPORARY TABLE vrTmp AS (SELECT vr.*, v.Code';
commit;
EXCEPTION
WHEN OTHERS THEN
RAISE;
END KP_PRC;
Mybatis xml.
<select id="kpSpCall" statementType="CALLABLE">
{CALL KP_PRC()}
</select>
