Handling Error Conditions

When an error is detected in a language environment function, the language environment sets the Net.Data RETURN_CODE variable with an error code.

You can use the following resources to handle error conditions:

• The Net.Data-supplied language environments return error codes that are documented in Net.Data Messages and Codes Reference.
• The database language environments, such as the SQL language environment, set the RETURN_CODE to error codes that are returned by the database management system (DBMS), called SQLCODEs. See the messages and codes documentation for your DBMS to learn more about the SQLCODEs used by your DBMS.
