Description
string
odbc_error ( [resource connection_id] )
Returns a six-digit ODBC state, or an empty string if there
has been no errors. If connection_id is
specified, the last state of that connection is returned, else the
last state of any connection is returned.
This function returns meaningful value only if last odbc query failed
(i.e. odbc_exec() returned FALSE).

odbc_exec().
