Parameters

Table 172-3 GET_MESSAGE Function Parameters

Parameter	Description
`errnum`	Specifies the error number. Example: `'972'` (for `ORA-00972)`
`product`	Specifies the product to which the error message applies Example: '`rdbms`'
`facility`	Specifies the error message prefix Example: `'ora'`
`language`	Specifies the language of the message. The parameter is case-insensitive. The default is `NULL`, which causes `GET_MESSAGE` to use the value of the `NLS_LANGUAGE` session parameter.
`message`	Specifies the output buffer for the retrieved message

Usage Notes

If the language parameter is set to NULL, then the value of the NLS_LANGUAGE session parameter is used as the default.

Examples

DECLARE
  s varchar2(200);
  i pls_integer;
BEGIN
   i:=utl_lms.get_message(601, 'rdbms', 'oci', 'french', s);
   dbms_output.put_line('OCI--00601 is: '||s);
END
