better error description

[Ing. Branislav Gerzo]

Hello all,

exist a better error description for DBI errors? I have quite complex
datastructure, I'm saving it to DB, using ODBC and MS SQL 2000. I get
only:
DBD::ODBC::st execute failed: [Microsoft][ODBC SQL Server Driver]Invalid charact
er value for cast specification (SQL-22018)(DBD: st_execute/SQLExecute err=-1) a
t ... line 291.

my connection string:
$dbh = DBI->connect('dbi:ODBC:regist');    # connect to MSSQL db
$dbh->{RaiseError} = 1;                    # show errors

thanks
