int $maxdb_stmt->affected_rows;
maxdb_stmt_affected_rows() returns the number of rows affected by INSERT, UPDATE, or DELETE query. If the last query was invalid or the number of rows can not determined, this function will return -1.
Returns:
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.

<?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } /* create temp table */ $maxdb->query("CREATE TABLE temp.mycity LIKE hotel.city"); $query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?"; /* prepare statement */ if ($stmt = $maxdb->prepare($query)) { /* Bind variable for placeholder */ $code = 'N%'; $stmt->bind_param("s", $code); /* execute statement */ $stmt->execute(); printf("rows inserted: %d\n", $stmt->affected_rows); /* close statement */ $stmt->close(); } /* close connection */ $maxdb->close(); ?>
Procedural style
<?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); } /* create temp table */ maxdb_query($link, "CREATE TABLE temp.mycity LIKE hotel.city"); $query = "INSERT INTO temp.mycity SELECT * FROM hotel.city WHERE state LIKE ?"; /* prepare statement */ if ($stmt = maxdb_prepare($link, $query)) { /* Bind variable for placeholder */ $code = 'N%'; maxdb_stmt_bind_param($stmt, "s", $code); /* execute statement */ maxdb_stmt_execute($stmt); printf("rows inserted: %d\n", maxdb_stmt_affected_rows($stmt)); /* close statement */ maxdb_stmt_close($stmt); } /* close connection */ maxdb_close($link); ?>
