(PECL)maxdb_stmt_affected_rows

(no version information, might be only in CVS)maxdb_stmt->affected_rows -- Returns the total number of rows changed, deleted, or inserted by the last executed statement

Description

Procedural style :int maxdb_stmt_affected_rows (resource stmt)

Object oriented style (property):class stmt {

int 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.

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 or the number of rows can not determined.

Example

Пример 1. Object oriented style


<?
$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();

?>

Пример 2. Procedural style


<?
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
/*check connection*/
if (maxdb_connect_errno()){
printf("Connect failed: %s\n", maxdb_connect_error());
exit();
}
/*create temp table*/
maxdb_query($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);

?>

The above examples would produce the following output:

rows inserted: 4
