Finding Duplicate Records

This past weekend I had to find duplicate records in a table in one of my databases. I recalled staring at the screen thinking to myself, "Man, I know I have done this. How did I go about doing this. CRAP!" Then it clicked. I had an existing script that I did from a previous project tucked away in my SQL script bag of tricks. The script below is the most basic script used to find duplicates.

select pc, count(pc) as pctotal

Reset your primary key column (identity) in your MS SQL table

One the things I ran into, and I thought I would share, was that the Vault Configuration UI under the File Server Administration module within Windchill 10 doesn't allow you to update the mount paths. For this specific upgrade we needed to move the remote vault root folders and replica folders to a more central location on all of the remote cache servers. Prior to the upgrade the root and replica folders was located under the Windchill 9.1 Windchill folder (D:PTCWindchill_9.1WindchillVaults). For this upgrade we moved these folders to the root of the D drive (D:Windchill_Vaults).

After the upgrade of the master server  was complete all of the root and replica folder mounts were in...
