Answer 2

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：

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

Answer 3

Declare @Name VARCHAR(100)

Select @Name = 'Praveen(403162)'

Select @Name = SUBSTRING(@name,PATINDEX('%[0-9]%',@Name),LEN(@Name))
Select SUBSTRING (@Name,1,6)
