Hello Andrew...

I already tried to do that, but it didn't work.

PostGresQL return me a ERROR saying that the syntax was invalidates.



But thank you even so for the help.

I have never done any of this, but looking at your code, it seems that
you would want to change the select in the stored procedure to something
like:

'SELECT usuario FROM user WHERE user = $1'

This should only return the full user name as desired, I think. Unless
you are wanting something more "generalized", so you can do 'SELECT *',
then isolate a column (any one of them, however many there are) from the
result set - I am certain there is a way to do it, but having never
played around with this, I am unable to offer much more advice.
