I have SQL Server 2005 Express installed. Later I upgraded to SQL Server 2008. I don't know much about instances, but when I log into SQL Server 2005 and I log into SQL Server 2008 it is showing the same number of databases. Also, when I create a database in SQL Server 2008 it is showing it in SQL Server 2005.
Any Idea how can I create a separate SQL Server 2008 instance?
If possible please explain step by step.
Thanks
An instance of a SQL Server database is just a named installation of SQL Server. The first one you install on any given machine typically is the default instance, which has no specific name - you just connect to it using the (local) name or the name of the server machine.
SQL Server Express typically installs as a SQLExpress instance - so the instance is called SQLExpress, and you connect to it using (local)\SQLExpress or .\SQLExpress or MyServerMachine\SQLExpress.
SQL Server instances are totally independent of one another, and you can basically install as many as you like - you just have to make sure to use unique instance names for each. But when you run the SQL Server Installation again, it will show you what instances are already installed, and prompt you for a new instance name for a new installation. No harm done.
Run the install program again, and when prompted whether you want a default or a named instance, specify a named instance with a different name. A default instance make looks like this:
servername
A named instance looks like this:
servername\instancename
"you can basically install as many as you like"
There are limitations, like 50 in 2008.
http://technet.microsoft.com/en-us/library/aa174516(v=sql.80).aspx
Microsoft does not support more than 16 instances on a single computer or failover cluster.
There are a few more limitations.

I have installed SQL Server and SSMS. And I open SSMS. The Connect to Database Engine Dialog is shown. But the Server Name is empty.
I don't know how to create a Server Name.
And I don't know where.
I also have tried to choose a fullpath name or local. But that doesn't work.
Can anybody help me? Oh... for both (SQL Server Express plus Management Studio I have the latest version).
In the drop down box for "Server Name" choose the option for <Browse for more...>. This will then give you a further window where you should see your instance listed under Local Servers:
One of the following:
You have installed Sql Server (not just SSMS), and during installation you specified a SQL Server instance for your computer and you DIDN'T specify an instance name. In that case you must
Make sure that the SQL Server service, called MSSQLSERVER, is running.
Connect to it with the name . (yes, just a dot)
You have installed Sql Server, and during installation you specified a SQL Server instance for your computer and you DID specify an instance name. In that case you must
Make sure that the SQL Server service, called MSSQLSERVER, is running.
Connect to it with the name .\InstanceName
You have install Sql Server Express.
Make sure that the SQL Server Express service is running. (I think the service name is also MSSQLSERVER)
Connect to it with the name .\SqlExpress
You have not installed any Sql Server version but you may have installed Visual Studio or something that include Sql tools, including LocalDb
start a localdb instance running with a command that is something like this (depending on your installed version):
'C:\Program Files\Microsoft SQL Server\150\Tools\Binn\SqlLocalDB.exe' start
Connect to it with the name, (localdb)\MSSQLLocalDb
You have not installed any Sql Server instance on your machine, and you are expecting to find a Sql Server instance somewhere on your network.
In this case you need someone who knows, to tell you the server name.
(You can create and start localdb instances with other names, MSSQLLocalDb is just the default or not having specified a name)
Start a service with e.g. PowerShell: Start-Service MSSQLSERVER or look for the service in the Windows' ⚙️ Services GUI you can find from Start Menu search.
I have Microsoft SQL Server manager version 18.8 installed to my PC, as well as SQL Server 2019. Both are installed on my PC. I need to locally create and manage a database.
I am trying to connect the SSMS but it's not working.
I entered to the services and restarted everything
and I also enabled TCP/IP in configuration manager.
what should I do?
You have a named instance of SQL Server named SQLEXPRESS (this is shown in parentheses within the SQL Server service name "SQL Server (SQLEXPRESS)" in the Windows Services MMC snap-in.
You need to specify the instance-name in the Server name: field.
You can only omit the instance-name for default instances.
You need to specify .\SQLEXPRESS or (local)\SQLEXPRESS to be able to connect.
Try connecting using .\SQLEXPRESS as the server name.
It seems you have created an instance with the name SQLEXPRESS. With SQL server you can create "instances". Each instance is like its own separate database engine and has its own list of databases, users and so forth. There can be one default instance which would be just the computer name or .. In your case you have a named instance "SQLEXPRESS" which you need to address using .\SQLEXPRESS or <computername>\SQLEXPRESS.
I installed SQL Server 2017 Express as a named Instance alongside my default instance. After rebooting once - both were showing but the I could not connect to SQL Server Express remotely. I then followed the instructions to enable IP on SQL Express using configuration manager and rebooted. Now I can connect remotely but my default instance is showing NO databases!
Also in configuration manager, SQL Server Services does not show any of my instances so that I can check they are running (this was the care even prior to enabling the IP address on the protocol, and when I knew it definitely was running as I could connect to it)

Update:
I discovered if I launch SQL Server Configuration Manager 2016 rather than "SQL Server Configuration Manager" I can see all my servers.
SQL Server 2016 appears to be running as is SQL Server Express. There is also a "MSSQLServer" that is stopped - think this may be SQL Server 2012. Not sure at this stage which one had the databases.
Ok so for anyone in a similar situation / panic. Do the following.
Look to see what other SQL Server configuration mangers are showing up. If you have installed multiple versions over the years chances are you'll see more than one.
Try using one of the later ones. You can see the file path too if you need it here.
If you manage to see a list of your database servers, check which are enabled and disabled. I had to disable SQL Server (SQLExpress) first before I could enable SQL Server (MSSQLServer), which in my case referred to SQL Server 2012.
If you want to have SQL Server Express running as a named server running alongside your default server, make sure you assign it a different port number (e.g. 1435) in the SQL Server Network Configuration>Protocols for SQL Express>TCP/IPALL section in SQL Server configuration manager.
I've had this identical problem on several laptops. The sequence of events is this:
I installed SQL Server 2012 with a named instance called SQL2012, to include SSRS, SSIS and SSAS multi-dimensional. This works fine.
I installed service pack 2.
I installed a second named instance called TABULAR, which includes only SSAS (tabular model).
The problem then comes when I try to connect to the original SQL2012 instance - it won't connect and shows this:
If I go into Configuration Manager, I see this:
If I go into management console and right-click on this SQL Server service, I can start it:
This solves the problem of connecting to the database engine, but the services still show up as an error in configuration manager (even after refreshing).
A few notes which may help:
I'm running Windows 10 Professional (but the problem also showed up on laptops running Windows 7 Professional)
I have SSMS, SSRS, SSIS and SSAS (and also SQL Server Agent) set up to run automatically
If I restart the laptop, I'm back to square one and have to restart the service again
the tabular instance works fine, and I can connect to it OK
I've tried to find other people with the same problem, but can't! Can anyone assist please? Thanks.
Just a guess... I can see on the screen the other instance of SQL Server installed on your machine (SQLEXPRESS) so, maybe you have other SQL Server instances of another version, 2008 for example... If so, maybe you need to install the latest SP on them.
Check quote from here
If you have SQL Server 2012 running side-by-side on the same machine
with SQL Server 2008/2008 R2, then you need to have SQL Server 2008
SP3 or later (or) SQL Server 2008 R2 SP1 or later.
I installed SQL Server 2008 (SQL Server 2005 was already installed) on my XP box and name the local instance of the database so that it wouldn't clash with SQL Server 2005.
Now I want to change the mapping of (local) from SQL Server 2005 to my non-standard named SQL Server 2008 instance. Anybody know how to do this?
I'm afraid Mladen is correct.
You can move the db's from one
instance to another using
attach/detach or backup/restore.
You can transfer all logins (if
needed) with this method.
You can move SQL Agent scripts by
right-clicking on them on the existing server and selecting
generate script then running that
script on the new server.
.
You will have to do the following (Assuming you'd like to make 2008 your default instance):
Install 2005 named instance.
Move the default to the named using above method.
Uninstall 2005 default instance.
Install 2008 default instance.
Move the named to the default using above method.
Uninstall 2008 named instance.
Good luck!
nope. you'll have to reinstall both.
Create an alias in the sql config manager. Enable named pipes for your instance with surface area config and you will be in business.
