How to use Powershell string functions

25 June,2012 by Tom Collins

When developing Powershell scripts for managing SQL Server Instances , eventually you will need to manipulate some strings.

In this case , I had to get the server name of a SQL Server instance reference – the part before the ‘\’ .

Use the Powershell Substring  and IndexOf  functions – for deriving a substring based on the position of a delimiter.

I’ve included examples of LTRIM,RTRIM and substring with a set position.



#IndexOf (equivalent of CHARINDEX) 
#substring based on IndexOf
