⟩ PHP MSSQL - How To Create an Identity Column?
Many tables require an ID column to assign a unique ID number for each row in the table. For example, if you have a table to hold forum member profiles, you need an ID number to identify each member. To allow SQL Server to automatically assign a new ID number for each new record, you can define the ID column with IDENTITY attribute as shown in the following sample script:
<?php
$con = mssql_connect('LOCALHOST','sa','GlobalGuideLine');
mssql_select_db('GlobalGuideLineDatabase', $con);
$sql = "CREATE TABLE ggl_users ("
. " id INTEGER IDENTITY NOT NULL"
. ", name VARCHAR(80) NOT NULL"
. ", email VARCHAR(80) NULL"
. ", time DATETIME NULL"
. ")";
$res = mssql_query($sql, $con);
if (!$res) {
print("Table creation failed with error: ");
print(" ".mssql_get_last_message()." ");
} else {
print("Table ggl_users created. ");
}
mssql_close($con);
?>
