Question

I have a lookup table with id(primary key), name, value and branchId as the columns. Currently I have a set of data with the branchId being the same for the entire records. I need to duplicate the data with same values for the name and value columns, but a different value of branchId in the same table.

Any help with the query/script to achieve this would be appreciated.

Thanks in advance!

If id is an IDENTITY, its values will be produced automatically:

INSERT INTO tableX                    --- the name of your table
    (name, value, branchID)
SELECT 
    name, value, 23                   --- branch to be added
FROM
    tableX
WHERE
    branchID = 12 ;                   --- the existing branch

For a set of branchID values, you can CROSS join to an existing a table (or create one on the fly):

INSERT INTO tableX                    
    (name, value, branchID)
SELECT 
    t.name, t.value, ins.branchID
FROM
        tableX AS t
    CROSS JOIN
        ( VALUES
            (1), (5), (7), (9), (10)      --- branchIDs to be inserted
        ) AS ins (branchID)
WHERE
    t.branchID = 12 ;                     --- the existing branchID
