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 statement

Description

Procedural style :

int mysqli_stmt_affected_rows ( mysqli_stmt stmt )

Object oriented style (property):

class mysqli_stmt { int affected_rows }

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.

Return Values

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.
