@@Error

Answer / sisira

you can handle
RAISEERROR

Answer / bolisettyvaas

In SQL Server 2000 there is no powerful error handling like
.Net. But you can use one global variable @@ERROR. So after
every dml statement, you can retrieve this variable value
and verify if the value is not equal to 0 then it means some
error occured. otherwise no errors in the last executed
statement.
