This page was last edited on 8 June , at The directory structure, registry structure, and service name all reflect the specific instance name you identify during setup. An instance is either the default, unnamed instance, or it is a named instance. When SQL Server is in installed in the default instance, it does not require a client to specify the name of the instance to make a connection. The client only has to know the server name.
A named instance is identified by the network name of the computer plus the instance name that you specify during installation.
Determining SQL Server File Locations and Version for Time Matters
The client must specify both the server name and the instance name when connecting. By default, SQL Server installs in the default instance unless you specify an instance name. SQL Server Express, however, always installs in a named instance unless you force a default installation during setup. Also you can install only one default unnamed instance but you can install many named instances. Many third party software will usually use a default named instance although they may not mention it.
The reason is clear from the above answers, standard versions installs an unnamed instance by default while the Express version installs a named instance by default. It is important to know about the difference from this perspective because if you have 2 or 3 DB Servers running, you might never connect to the right version. It can significantly increase your troubleshoot time, if you don't know how to connect to a named vs unnamed instance.
Yet another practical difference: SQL and up allow you to install 16 or more instances per system. You can also cap memory and assign limit processor usage per instance. You could also create an instance for vendor written apps that 'need' system admin privileges, so you don't put your other applications at risk. One of the best reasons is seperation of databases. If you are developing your own application and packaging SQL Express with it, then it makes sense to install it into it's own instance.
