An integer greater than zero indicates the number of rows affected or retrieved.
|
|
Zero indicates that no records where updated for an UPDATE/DELETE statement, no
|
|
rows matched the WHERE clause in the query or that no query has yet been executed.
|
|
-1 indicates that the query has returned an error or the number of rows can not determined.
