    Experts..

    Table 1 looks like this:

    Col1 Col3

    String1 String1.String2

    .....

    I want to transform the table so it would look like this:

    Col Col2

    String1 String2

    ....

    Where String1 , String2 are of varchar type

    So basically I need to work on Column 2. Chop of the characters that are present in Column1

    This is done on SQL server 2005 express.

    Thanks for the help!

    To help those who are willing to help you, please post table definition,sample data and expected results, using the outline/method which you will be able to read and refer to by clicking on the first link in my signature block.

    If everything seems to be going well, you have obviously overlooked something.

    CREATE TABLE [dbo].[BldgA](

    [CX] [nvarchar](255) NULL,

    [Point] [nvarchar](255) NULL,

    [Link] [nvarchar](255) NULL

    )

    sample data:

    BldgA G1.EngCoolTemp G1.EngCoolTemp.C1.GenLoCoolT

    I want to change it to look like this:

    BldgA G1.EngCoolTemp C1.GenLoCoolT

    Script for the data:

    INSERT INTO [database1].[dbo].[BldgA]

    ([CX]

    ,[Point]

    ,[Link]

    )

    VALUES

    ('BldgA'

    ,'G1.EngCoolTemp'

    ,'G1.EngCoolTemp.C1.GenLoCoolT'

    )

    Consider this, though you would need to confirm that the @Val1 is in fact the prefix of @Val2:

    declare @Val1 varchar(50)

    , @Val2 varchar(50)

    select @Val1 = 'G1.EngCoolTemp'

    , @Val2 = 'G1.EngCoolTemp.C1.GenLoCoolT'

    select substring(@Val2, len(@Val1)+2, 50)

    This is what I did:

    update BldgA

    set Link1 = substring(Link1,len(point)+2, len(link1))

    It worked.

    Thanks

    I'm not 100% sure of the requirement. If the goal is just to remove the string in the column Point from the Link column or if there is more too it than that. At any rate, here is another way to remove the string fragment:UPDATE dbo.BldgA

    SET Link = REPLACE(Link, Point + '.', '')
