Question

I have table with data 1/1 to 1/20 in one column. I want the value 1 to 20 i.e value after \'/\'(front slash) is updated into other column in same

Answer 1

Maybe something like this:

First some test data:

DECLARE @tbl TABLE(Column1 VARCHAR(100))

INSERT INTO @tbl
SELECT '1/1' UNION ALL
SELECT '1/20' UNION ALL
SELECT '1/2'

Then like this:

SELECT
    SUBSTRING(tbl.Column1,CHARINDEX('/',tbl.Column1)+1,LEN(tbl.Column1))
FROM
    @tbl AS tbl

SELECT SUBSTRING(ParentBGBU,0,CHARINDEX('-',ParentBGBU,0)) FROM dbo.tblHCMMaster;
