How to analyze SQL indexes through the Command Line

As index fragmentation affects query performance, it is highly important to trace SQL Server indexes in order to timely perform database maintenance.

  1. Click Start, type ‘cmd’ in the Search programs and files text box, and press ENTER. The Command Prompt opens.

  2. Specify the operation you want to perform and the required parameters and arguments (actions you want to run) in the Command Prompt, for example as follows:

dbforgesql.com /analyzeindex [/switch1[:value | [parameter1:value parameter2:value ..]] /switch2 ..]
  1. Press ENTER to run the process.

Select corresponding command line switches to perform the required operations:
