MAXDB_AFFECTED_ROWS(3) 1 MAXDB_AFFECTED_ROWS(3)maxdb_affected_rows - Gets the number of affected rows in a previous MaxDB operation
Procedural style
SYNOPSIS
int maxdb_affected_rows (resource $link)
DESCRIPTION
Object oriented style
int$maxdb->affected_rows ()
maxdb_affected_rows(3) returns the number of rows affected by the last INSERT, UPDATE, or DELETE query associated with the provided $link
parameter. If this number cannot be determined, this function will return -1.
Note
For SELECT statements maxdb_affected_rows(3) works like maxdb_num_rows(3).
The maxdb_affected_rows(3) function only works with queries which modify a table. In order to return the number of rows from a SELECT
query, use the maxdb_num_rows(3) 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 statement, no rows matched the WHERE clause in the query or that no query has yet been executed. -1 indicates that the number of
rows affected can not be determined.
EXAMPLES
Example #1
Object oriented style
<?php
$maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");
/* check connection */
if (maxdb_connect_errno()) {
printf("Connect failed: %s
", maxdb_connect_error());
exit();
}
maxdb_report (MAXDB_REPORT_OFF);
$maxdb->query("DROP TABLE mycustomer");
maxdb_report (MAXDB_REPORT_ERROR);
/* Insert rows */
$maxdb->query("CREATE TABLE mycustomer AS SELECT * from hotel.customer");
printf("Affected rows (INSERT): %d
", $maxdb->affected_rows);
$maxdb->query("ALTER TABLE mycustomer ADD Status int default 0");
/* update rows */
$maxdb->query("UPDATE mycustomer SET Status=1 WHERE cno > 50");
printf("Affected rows (UPDATE): %d
", $maxdb->affected_rows);
/* delete rows */
$maxdb->query("DELETE FROM mycustomer WHERE cno < 50");
printf("Affected rows (DELETE): %d
", $maxdb->affected_rows);
/* select all rows */
$result = $maxdb->query("SELECT title FROM mycustomer");
printf("Affected rows (SELECT): %d
", $maxdb->affected_rows);
$result->close();
/* Delete table Language */
$maxdb->query("DROP TABLE mycustomer");
/* close connection */
$maxdb->close();
?>
Example #2
Procedural style
<?php
$link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");
if (!$link) {
printf("Can't connect to localhost. Error: %s
", maxdb_connect_error());
exit();
}
maxdb_report (MAXDB_REPORT_OFF);
maxdb_query($link,"DROP TABLE mycustomer");
maxdb_report (MAXDB_REPORT_ERROR);
/* Insert rows */
maxdb_query($link, "CREATE TABLE mycustomer AS SELECT * from hotel.customer");
printf("Affected rows (INSERT): %d
", maxdb_affected_rows($link));
maxdb_query($link, "ALTER TABLE mycustomer ADD Status int default 0");
/* update rows */
maxdb_query($link, "UPDATE mycustomer SET Status=1 WHERE cno > 50");
printf("Affected rows (UPDATE): %d
", maxdb_affected_rows($link));
/* delete rows */
maxdb_query($link, "DELETE FROM mycustomer WHERE cno < 50");
printf("Affected rows (DELETE): %d
", maxdb_affected_rows($link));
/* select all rows */
$result = maxdb_query($link, "SELECT title FROM mycustomer");
printf("Affected rows (SELECT): %d
", maxdb_affected_rows($link));
maxdb_free_result($result);
/* Delete table Language */
maxdb_query($link, "DROP TABLE mycustomer");
/* close connection */
maxdb_close($link);
?>
The above example will output something similar to:
Affected rows (INSERT): 15
Affected rows (UPDATE): 15
Affected rows (DELETE): 0
Affected rows (SELECT): 15
