检测SQL Server 2008 R2

Question

I've googled a day but the question is still question: how to detect SQL Server 2008 R2 on various Windows versions:

• via registry (would be our favorite solution),
• via file system ,
• via installer exit code ?

Installer developed with NSIS. Some additional informations:

Registry

Samples on the net are out of date or simply improper. Not just R2 but 2k8 detection is problematic too.

File system

I have no idea what files are especially from 2k8 R2.

Installer exit code

In some cases exits without error code (ie prerequisites missing).

Answer 1

try to execute this query:

SELECT @@Version

I get this result back:

Microsoft SQL Server 2008 R2 (RTM) - 10.50.1600.1 (X64) Apr 2 2010 15:48:46 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 5.2 (Build 3790: Service Pack 2)

is this enough? For me yes :)

Answer 2

you could use the WMI to listy all the microsoft product installed and then you could look foe the one you need

public static class MyClass
    {
        public static void Main()
        {
            ManagementObjectSearcher mos = new ManagementObjectSearcher("SELECT * FROM Win32_Product");
            foreach (ManagementObject mo in mos.Get())
            {
                Console.WriteLine(mo["Name"]);
            }


        }
    }

And before you try execute query provided by Davide (SELECT @@Version) you can check, that MSSQL service is running

using System.ServiceProcess;
var list = ServiceController.GetServices().ToList();
        if (list.Any(sc => sc.ServiceName.ToLower().Contains("mssql")))

Answer 5

I use below code in my application

 SqlDataSourceEnumerator sqldatasourceenumerator1 = SqlDataSourceEnumerator.Instance;
            DataTable datatable1 = sqldatasourceenumerator1.GetDataSources();
            foreach (DataRow row in datatable1.Rows)
            {
                if (Environment.MachineName.Equals(row["ServerName"]))
                {

                    isSqlServerPresent = true;
                    break;
                }
            }

The only issue is, this code works on when the machine is on network, but since in my case machine will be on network, so I was ok with this issue.

It gets me the local instance of SQL Server.

In fact if you want to list Servers in the network and SQL Servers instances on a machine or on the LAN, there are APIs for it.

There should be proper way to call NetServerEnum Windows API, for examples see:
