There are two inquire statements that can perform error checking: INQUIRE_SQL and INQUIRE_FRS. Both statements return error numbers and the associated error text using the constants errorno and errortext. INQUIRE_SQL returns the error number and text for the last executed OpenSQL database statement. INQUIRE_FRS returns information about the last executed forms statement.

Unlike the WHENEVER statement, an inquire statement must be executed immediately after the database or forms statement in question. The INQUIRE_SQL returns a generic error number in errorno by default. OpenSQL can be directed to return a local error number in errorno. For more information, see Local and Generic Errors (see page Local and Generic Errors).

Neither of the inquire statements suppress the display of error messages. Both of the inquire statements return a wide variety of information in addition to error numbers and text.

For a complete list of the information returned by INQUIRE_SQL, see the chapter "OpenSQL Statements.” For details about INQUIRE_FRS, see the Forms-based Application Development Tools User Guide.
