boolean parameters

[justinb]

Hi

I'm using OracleDialect with EJB RC1

I'm not sure if there is a proper way to do this, but I have a query like this:

SELECT x FROM Resource x WHERE :visibleOnly = false OR x.visible = true

Resource has a boolean property called "visible".

I get an Oracle error saying "Invalid column name". I checked the debug logs and noticed that hibernate was not changing the boolean values to sql 1s and 0s in the (impressive) sql that it generates. So now I've changed the query to

SELECT x FROM Resource x WHERE :visibleOnly = 0 OR x.visible = 1

and set the "visibleOnly" parameter to 1 or 0, and now it works...

Is this my mistake? Can I leave my query like it is now? Is it wrong to use booleans as parameters?

Thanks,
Justin

use a parameter or a query substitution (see the hibernate ref doc)
