dam_addError/dam

This function adds an error to the error list maintained by the OpenAccess SDK SQL engine. An error is added at the environment, connection or statement level. This error string is returned to the client. This is the only way to pass specific error information to the client. An IP function returns an error by adding an error using this function and then returning DAM_FAILURE.

Error messages added using this function are reported as SQL state HY000. Use dam_addErrorEx/dam_addErrorExW if you want to specify the SQL state. Using dam_addError is the recommended approach to report back errors to the client.
