According to documentation db_query() should return FALSE "if the query
was not executed correctly". This function calls _db_query() which
returns nothing in such cases (for example when the sql syntax is

Attached one-liner fixes this by adding return FALSE to _db_query().
It's from 4.6.1 but should apply to cvs without problems. Please apply
this patch also to 4.6 branch.

But there seems to be a problem with db_error(). It calls mysql_errno()
but it seems that errors are cleared after mysql_error() call. So
db_error() does not indicate any errors even if they occur.

I have moved the db_error part to http://drupal.org/node/25673

I forgot to make a patch for database.pgsql, but the change is the same.

Patch against current cvs, have both mysql and postgresql db. Maybe now
someone will take a look at it?

The patch makes sense to me. It shoudl have been rolled from the Drupal
base directory, which I did.
