maxdb_stmt_affected_rows

Returns the total number of rows changed, deleted, or inserted by the last executed statement (PECL maxdb:1.0-7.6.00.38)
int maxdb_stmt_affected_rows ( resource stmt )

Procedural style :

Object oriented style (property):

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.

Examples

Example 1251. Object oriented style

<?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();
?>


Example 1252. 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);
?>


The above examples would produce the following output:

rows inserted: 4
