问题描述

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

推荐答案

你可以这样做:

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

如果您想在一行中执行此操作:

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
