Question

I have a database on my student server, I need to go to my university if I want to access the database properties using the SQL server DBMS, it is a pain. I want to know if I can change the identity specification by using SQL on a specific table? I cannot insert to a table as this is not selected to yes, I want to be able to make these changes from home can I do this?

I was researching how to access tables and change some properties, and came across something like this:

Set IDENTITY_INSERT TableName ON

I want to be able to do this using a php script and some SQL, like this:

$query = "IDENTITY_INSERT customers ON ";

        $result = sqlsrv_query( $conn, $query, array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));

        if( $result === false)
        {
            echo "Error in query preparation/execution.\n";
            die( print_r( sqlsrv_errors(), true));
        }

        else
        {
            echo'worked';
        }

will this work?

Here is my rough attempt at doing this:

<?php
$serverName = "servername";
    $connectionInfo = array("UID" => "username", "PWD" => "password",      "Database"=>"database");
    $conn = sqlsrv_connect( $serverName, $connectionInfo);

    if( $conn === false ) // note the format of ‘equals’
    {
         echo "Could not connect.\n";
         die( print_r( sqlsrv_errors(), true));
    }



        $query = "SET IDENTITY_INSERT customers ON ";

        $result = sqlsrv_query( $conn, $query, array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));

        if( $result === false)
        {
            echo "Error in query preparation/execution.\n";
            die( print_r( sqlsrv_errors(), true));
        }

        else
        {
            echo'worked';
        }

?>

Thank you.

IDENTITY_INSERT is the correct syntax, although you appear to have missed off the SET keyword in your usage. See this line:

$query = "IDENTITY_INSERT customers ON ";

Change to:

 $query = "SET IDENTITY_INSERT customers ON ";
