Good day!I change my database from mysql to mssql, so I need to change the connection code in my php. I’m not familiar about the codes using mssql. Now cannot connect to my database.I used the following:php 5.1.4 IIS 6.0Microsoft SQL Server 2005 Express EditionSQL Server Management Studio Express Here is my code:

<?php//session_start(); //session_regenerate_id(); //if($_SESSION['loggedin']){ //the user is already logged in, lets redirect them to the other page   //  header("Location:company.php"); //} $server = "ISM\SQLEXPRESS";//$db = "dbtest";$connectOptions = array("Database" => "dbtest");//Because UID and PWD are not specified in the connection option, the connection is made with Windows Authentication.$conn = mssql_connect($server) or die("Could not connect");$selected = mssql_select_db($connectOptions)or die("Cannot select DB");            $department = $_POST['department'];            $username = $_POST['username'];         $sql=mssql_query("SELECT `Department`, `Username` FROM `tbluser` WHERE `Department` = '{$department}' AND Username = '{$username}'") or die(mssql_min_error_severity());         $ct = mssql_num_rows($sql);               if($ct == 1) { // im guessing this means that the user is valid. $_SESSION['loggedin'] = true; // now that the user is valid we change the session value.             $row = mssql_fetch_assoc($sql);   						//$_SESSION['username'] = $row['Username'] ;			//$_SESSION['department'] = $row['Department'];						$Departments=array('aa', 'bb', 'cc', 'dd', 'ee', 'ff', 'gg', 'hh', 'ii', 'jj');						if (in_array($row['Department'], $Departments)){					header ('Location:company.php');			}else{					echo "Incorrect Username or Department";					header ('Location:index.php');			}		}?>

And when I run this code the result is:Cannot select DBThank you in advance

The select db doesn't take an array, just a string of the database name. Look at the examples here:http://www.php.net/manual/en/function.mssql-select-db.php
I try this code:
$db = "dbtest"; $selected = mssql_select_db($db) or die('MSSQL error' . mssql_get_last_message());

and the output is:MSSQL error.The several principal "[domain name]\IUSR_[computer name]" is not able to access the databse "database name" under the current security context.Honestly, I have no idea regaeding this error.

I try a new code:

$db = "dbtest"; $selected = mssql_select_db($db) or die('MSSQL error' . mssql_get_last_message()); 

and the output is:MSSQL error.The several principal "[domain name]\IUSR_[computer name]" is not able to access the databse "database name" under the current security context.Then I research about this error and I find a step to fix the error, but I can't follow the steps because I can't find what they say in the steps.here is the step:To fix this SQL Server Management Studio 2008 (maybe in 2005 too), please do the following: 1.Open SQL Server Management Studio 2008 2.Connect to the database server as normal 3.Press F7 to open the "Object Explorer Details" window or click "View" >> "Object Explorer Details" 4.In the object explorer details window expand by double click on "Databases" 5.Right click on the column header and deselect "Collation" from the menu that will pop up 6.From the object explorer, refresh the "Databases" I don't know what the appearance is if I am already in the Object Explorer Details view. And I can’t see the column header and also the Collation.

I try to configure the sql server I do the ff:1. I open the SQL Server Management Studio Express2. I connect using Windows Authentication3. Under Databases folder where my database was there.4. I click the plus sign on Databases5. Then my dbtest was appearing and I click the plus sign.6. On Security folder I click the plus sign7. Then the Users folder was appear8. I right click on the DOMAIN\SQLServer2005MSSQLUser$COMPUTERNAME$SQLEXPRESS.9. On the General Tab-> Ownded Schemas I try to check the db_accessadmin and also I accidentall check the checkbox of db_owner and db_securityadmin. And Role Members I check also the db_accessadmin.After that I reboot the server.Then i run again my webpage.And the result is:Cannot select DBBefore I configure my sql server the output of my codes is:MSSQL error.The several principal "[domain name]\IUSR_[computer name]" is not able to access the databse "database name" under the current security context.After that I configure again my sql server to uncheck the checkboxes that I checked before. And I don't know why on the Owned Schema the checkboxex that I check was hiding so I can edit it, but on the Role members I uncheck the db_accessadmin.I don't have any idea to fix my error: I really needed to fix it but I don't know what to do and I'm a little bit scared to configure the sql server, because I am new user of it.:)

I don't have a copy of SQL Server 2005 handy, but you'll want to give the user the db_owner permission for that database. Unless you're setting up access for specific users who you don't want to do everything, or you want to look into each permission to find out what it means and whether your application needs it, it will be fine to grant all permissions to the user.Also, you can use this function to print out the error message from SQL Server instead of your own message:http://www.php.net/manual/en/function.mssq...ast-message.php

Before, I used that function,but when I configure my SQL Server, I can't view the errors.
