Why does this statement work fine in workbench but not in Java. 

SET @sqlstmt := IF( @exist <= 0, 'select ''INFO: Key does not exist.''', 'ALTER TABLE `SOMETABLE` DROP FOREIGN KEY `SOMEKEY`');

In Java I get 

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 'SET @sqlstmt := IF( @exist <= 0, 'select ''INFO: Key does not exist.''', 'ALTER ' at line 1

  • Those quotes look weird. Shouldn't it be " instead of two single quotes? Commented Jun 24, 2014 at 15:10
  • have you tried simplifying the query to isolate the part causing the error? Commented Jun 24, 2014 at 15:10
  • And do you know what JDBC uses as delimiter? Commented Jun 24, 2014 at 15:11
  • I had thought a single quote should be escaped by a single quote when already inside single quotes. Isn't that true? Commented Jun 24, 2014 at 15:11
  • I haven't seen it before. Could you try to escape these quotes not with other quotes but with backslashes? Commented Jun 24, 2014 at 15:16

It turned out to be the fact that multiple statements were being executed (separated by semicolons). In JDBC MYSQL you need allowMultiQueries=true
