How to get a substring from a formatted string

Question

I would like to get a substring 403162 from the given string Praveen(403162) in sql?

Answer 1

You can do it like this:

DECLARE @searchString NVARCHAR(20) = 'Praveen(403162)'
DECLARE @startFrom INT= CHARINDEX('(',@searchstring) + 1
DECLARE @length INT = CHARINDEX(')',@searchstring) - @startFrom
SELECT SUBSTRING(@searchstring,@startFrom, @length) AS RESULT

If you want to do this in one line:

DECLARE @searchString NVARCHAR(20) = 'Praveen(403162)'
SELECT SUBSTRING(@searchstring,
       CHARINDEX('(',@searchstring) + 1, 
       CHARINDEX(')',@searchstring) - CHARINDEX('(',@searchstring) - 1) AS RESULT
