PHP MSSQL - How To Insert Data with NULL Values?
✍: Guest
There are two ways to provide NULL value to a column in an INSERT statement:
The following tutorial exercise inserts two rows. Both of them have NULL values. But they were inserted differently:
<?php $con = mssql_connect('LOCALHOST','sa','FYIcenter'); mssql_select_db('FyiCenterData', $con); $sql = "INSERT INTO fyi_links" . " (id, url, notes, counts, time)" . " VALUES (101, 'dev.fyicenter.com'," . " NULL, NULL, NULL)"; $res = mssql_query($sql,$con); if (!$res) { print("SQL statement failed with error:\n"); print(" ".mssql_get_last_message()."\n"); } else { print("One data row inserted.\n"); } $sql = "INSERT INTO fyi_links (id, url) VALUES (" . " 102, 'dba.fyicenter.com')"; $res = mssql_query($sql,$con); print("Another data row inserted.\n"); mssql_close($con); ?>
If you run this script, you will get:
One data row inserted. Another data row inserted.
