How to install a second instance of SQL Server?<\/em><\/strong><\/h4>\n\n\n\n

During the first installation of SQL Server, there are two options for the instances, te first option is to install the default instance, the other option is to install a named instance. To install another instance, follow the steps below and adapt according to the SQL Server configuration.<\/p>\n\n\n\n

Add multiple additional instances to a SQL Server<\/h2>\n\n\n\n

To do this, run the installation from the executable and install the new instance of the RDBMS : SQL Server Database Engine. With a SQL Server Developer<\/a>, Standard or Enterprise version, SQL Server names the instance MSSQLSERVER<\/em><\/strong> by default. However, the name of the named instance is free.<\/p>\n\n\n\n

One default instance named MSSQLSERVER per server<\/h2>\n\n\n\n

Furthermore, with the SQL Server Express<\/a> Edition, run the installer twice. Then rename the new instance with a name other than the default instance, i.e. SQLExpress<\/em><\/strong>. If installing an additional database instance is impossible, then an interesting alternative is to create another database in the existing instance!<\/p>\n\n\n\n

Indeed, simply use SQL Server Management Studio with the right privileges or a SQL script. To go further, find out here how to create a database using SSMS and no SQL script<\/a>. When connecting to a default instance, specifying the instance name is not necessary.<\/p>\n\n\n\n
