Get-MssqlInstances #


Provides information about the MSSQL instances and their database files


Get-MssqlInstances [-show] [-ProgressAction <ActionPreference>] [<CommonParameters>]


The function returns various information for each local instance of the MSSQL server as PSCustomObject. In addition, the Files property of each object is filled with the file properties of the instance. This includes the date of the last file modification as well as the size of the database.

The data is mainly accessed via the registry. In addition, the status values of the SQL service and the SQL browser are evaluated.

If the query is performed with administrative rights, it is also checked whether the firewall has opened the UDP port of the SQL browser and whether there is a firewall rule for the SQL server service.

The information is additionally displayed on the monitor via the Show parameter.

The advantage of the PSCustomObject data type over a hashtable is, for example, the simple access to the property names such as: $instances[1].PatchLevel as well as further processing with Format-Table and Format-List.
