For many data retrieval needs from scripts ADO.NET can be a little too heavy. There we go we see how the data from the WMI query was transferred to an SQL TableĪnother method to execute a query in PowerShell is to use ADO.NET libraries, which requires creating a DataSet, then creating a DataAdapter, and finally filling the DataAdapter. The output is queried from the table tbl_PoShDisk The below screen shot shows the steps and the results. Invoke - Sqlcmd params - Query " SELECT * FROM tbl_PosHdisk" | format - table - AutoSize We filter the content to pick only DriveType=3 which is the type number for local drives. The simplest way to get the disk space information is with the Win32_LogicalDisk class. But of course, WMI has these nifty uses as well. While automation was one of the reasons for bringing WMI, the primary focus was to provide developers with handles that they could use when creating applications for Windows.

When sending data within a system (such as a PowerShell object to a cmdlet), the process is straightforward. The question comes up so frequently that I decided to write this article. I’ve been asked on several occasions about how to store the output of PowerShell WMI data into the SQL table. PowerShell has replaced the traditional way of scripting that used many legacy scripting practices to monitor SQL instances. NET Framework and uses Object Models such as COM, ADSI, ADO, and WMI. PowerShell has become the ultimate choice for many database administrators because of its efficient way of handling and managing automation in a simple, quick way.
