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.
