⟩ PHP MSSQL - How To Update Existing Rows in a Table?
Updating existing rows in a table requires to run the UPDATE statement with a WHERE clause to identify the row. The following sample script updates one row with two new values:
<?php
$con = mssql_connect('LOCALHOST','sa','GlobalGuideLine');
mssql_select_db('GlobalGuideLineDatabase', $con);
$sql = "UPDATE ggl_links SET notes='Nice site.', counts=8"
. " WHERE id = 102";
$res = mssql_query($sql,$con);
if (!$res) {
print("SQL statement failed with error: ");
print(" ".mssql_get_last_message()." ");
} else {
$number_of_rows = mssql_rows_affected($con);
print("$number_of_rows rows updated. ");
}
mssql_close($con);
?>
If you run this script, you will get something like this:
1 rows updated.
