    You can use following code snippet for reverse value after insert sql server or c#
    DECLARE @temp TABLE
    (
    ID INT IDENTITY(1,1)
    , Case_YourName NVARCHAR(50)
    , Case_Description NVARCHAR(50)
    )

    INSERT INTO @temp (Case_YourName, Case_Description)
    VALUES
    ('Phagu Mahato ', 'Will Management'),

    UPDATE @temp
    SET Case_YourName = SUBSTRING(Case_YourName, CHARINDEX(' ', Case_YourName), LEN(Case_YourName)) + ' ' + SUBSTRING(Case_YourName, 1, CHARINDEX(' ', Case_YoorName))
    SELECT * FROM @temp


    Or use this command
     INSERT Mytable (col1, col2) OUTPUT INSERTED.IDCol VALUES (@param1, @param2);

    Hi,

    UniqueIdentifier is one which gives you unique set of number which we cant keep it as Numeric or even integer because the range of GUID is bigger than any datatypes of numeric.

    We can do the following step to make this conversion works.



    CREATE FUNCTION STRTOUID()
    {
    DECLARE @guid VARCHAR(50)
    SET @guid = 'a89b1acd95016ae6b9c8aabb07da2010'
    SELECT CAST(
    SUBSTRING(@guid, 1, 8) + '-' + SUBSTRING(@guid, 9, 4) + '-' + SUBSTRING(@guid, 13, 4) + '-' +
    SUBSTRING(@guid, 17, 4) + '-' + SUBSTRING(@guid, 21, 12)
    AS UNIQUEIDENTIFIER)
    }


    You can invoke this function anywhere in the stored procedure and perform your operation.

    Thanks,
    Mani
