Returns: The number of affected rows by the last
query.
sybase_affected_rows() returns
the number of rows affected by the last INSERT, UPDATE or
DELETE query on the server associated with the specified link
identifier. If the link identifier isn't specified, the last
opened link is assumed.
This command is not effective for SELECT statements,
only on statements which modify records. To retrieve the
number of rows returned from a SELECT, use
sybase_num_rows().
注: This function is only available using the CT library interface to Sybase, and not the DB library.
