- ______________________________________________________________________
-
- o dbtsnewlen() is one of the DB-Library browse mode routines.
- See the Introduction for a detailed discussion of browse mode.
- o dbtsnewlen() provides information about the timestamp column.
- The WHERE clause returned by dbqual() contains a call to the
- tsequal built-in function. When such a WHERE clause is used in
- an UPDATE statement, the tsequal function places a new value in
- the updated row's timestamp column and returns the new times-
- tamp value to the application (if the update is successful).
- The dbtsnewlen() function allows the application to save the
- length of the new timestamp value, possibly for use with
- dbtsput().
-
- PARAMETERS:
- dbproc - A pointer to the DBPROCESS structure that provides the
- connection for a particular front-end/SQL Server process. It
- contains all the information that DB-Library uses to manage
-

- communications and data between the front end and SQL Server.
-
- RETURNS:
- The length (in bytes) of the updated row's new timestamp value.
- If no timestamp was returned to the application (possibly because
- the update was unsuccessful, or because the UPDATE statement did
- not contain the tsequal built-in function), dbtsnewlen() will
- return -1.
