MS SQL Server Interview Question:

PHP MSSQL - How To Get the Number of Affected Rows?

Submitted by: Administrator

If you insert multiple rows with a single INSERT statement, you can use the mssql_rows_affected() function to find out how many rows were inserted. mssql_rows_affected($connection) returns the number of affected rows of the last INSET, UPDATE or DELETE statement.

The following tutorial script shows you report back the number of rows inserted properly:

<?php
$con = mssql_connect('LOCALHOST','sa','GlobalGuideLine');
mssql_select_db('GlobalGuideLineDatabase', $con);

$sql = "INSERT INTO ggl_links"
. " SELECT id+1000, REVERSE(url), notes, counts, time"
. " FROM ggl_links WHERE id > 1000";
$res = mssql_query($sql,$con);
if (!$res) {
print("SQL statement failed with error: ");
print(" ".mssql_get_last_message()." ");
} else {
$number_of_rows = mssql_rows_affected($con);
print("$number_of_rows rows inserted. ");
}

mssql_close($con);

If you run this script, you should get:

2 rows inserted
