I'm trying to execute an action that involves multiple insert
queries. Rather than execute them sequentially, I'd rather build a
sql string containing all of the queries and only have one round trip
to the database. Using MDB2, though, I can't seem to do that. I've
separated each query with a semicolon, but I get a syntax error. When
I display the user info ($result->getUserInfo()) and copy the SQL from
the error message, I can execute the SQL just fine in CocoaMySQL.
Is this a limitation of MDB2? Am I using the wrong query separator?
I'm not seeing anything in the MDB2 documentation about this at all.
My generated SQL looks like this:
INSERT INTO object ( field1, field2, field3 ) VALUES ( value1, value2,
value3 ); INSERT INTO object_property ( field1, field2, field3 )
VALUES ( value1, value2, value3 ); INSERT INTO object_property
( field1, field2, field3 ) VALUES ( value1, value2, value3 ); ...;
INSERT INTO object_property ( field1, field2, field3 ) VALUES
( value1, value2, value3 );
Error:
[Native code: 1064] [Native message: 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 '; INSERT INTO object_property
( object_id, object_property, int_value) VALUES ' at line 1]
Thanks.
