mysqli_stmt_affected_rows(no version information, might be only in CVS)
mysqli_stmt->affected_rows -- Returns the total number of rows changed, deleted, or inserted by the last executed statementProcedural style :
mixed mysqli_stmt_affected_rows ( mysqli_stmt stmt )Object oriented style (property):
class mysqli_stmt {mysqli_stmt_affected_rows() returns the number of rows affected by INSERT, UPDATE, or DELETE query. If the last query was invalid, this function will return -1.
The mysqli_stmt_affected_rows() function only works with queries which update a table. In order to return the number of rows from a SELECT query, use the mysqli_stmt_num_rows() function instead.
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.
Notatka: If the number of affected rows is greater than maximal PHP int value, the number of affected rows will be returned as a string value.
