Basically, you need to execute the statement; there's no -l flag. Two common methods are: Preceding a SELECT with EXPLAIN. This only works for SELECT statements, so it's not a general solution Use Transactions. This is only good in 5.x Innodb tables, so it's not a general solution. This also doesn't help for SELECTS which you don't want to take time to execute. Neither of these work for me. The only decent general solution I've found is to create a test suite

From JSF validation: JSF 2 provides built-in integration with JSR-303 constraints. When you are using bean validation in your application, JSF automatically uses the constraints for beans that are referenced by UIInput values. The answer furthermore suggests using SeamFaces to validate the class-level constraints anyways. Unfortunately this is a non-option, since it introduces a somewhat massive
