fbsql_errno ( [resource link_identifier] )
Returns the error number from the last fbsql function, or
0 (zero) if no error occurred.
Errors coming back from the fbsql database backend don't issue
warnings. Instead, use fbsql_errno() to
retrieve the error code. Note that this function only returns the
error code from the most recently executed fbsql function (not
including fbsql_error() and
fbsql_errno()), so if you want to use it, make
sure you check the value before calling another fbsql function.

fbsql_warnings().
