MS SQL Server Interview Question:
PHP MSSQL - How To Delete Existing Rows in a Table?
Submitted by: AdministratorIf you want to remove a row from a table, you can use the DELETE statement with a WHERE clause to identify the row. The following sample script deletes one row:
<?php
$con = mssql_connect('LOCALHOST','sa','GlobalGuideLine');
mssql_select_db('GlobalGuideLineDatabase', $con);
$sql = "DELETE FROM ggl_links WHERE id = 1102";
$res = mssql_query($sql,$con);
if (!$res) {
print("SQL statement failed with error: ");
print(" ".mssql_get_last_message()." ");
} else {
$number_of_rows = mssql_rows_affected($con);
print("$number_of_rows rows deleted. ");
}
mssql_close($con);
?>
If you run this script, you will get something like this:
1 rows deleted.
If you run it again, no rows will be deleted. And you will get something like this:
0 rows deleted.
