and for my other problem

thanks for the link , but what I rellay need to do is to query
database based on a value of another field and fetch a value out of
there then compare it with the value in the current field

so I need to do something like :- db.table.field = IS_EXPR('value< db
(db.auth_user.name == "%s").slelect(db.auth_user.number)
[0].number'%request.vars.other_field_value)

it turned out that I need to surround the query with eval(), but I
failed to get things work since I'd many nested quotes that I needed
to handle but in the end I failed

so is this right ?
