Hi Satish,

maybe this piece of SQL code could help you... Please adjust the parameters @prefix and @offset. In the case you're satisfied with results, use the formulas in your UPDATE command.

Regards,
Radek

select * FROM (
    SELECT
        @prefix:="4GH" as cardnumber,
        @offset:=17 as university_id
    ) as vars
where 0 = 1

union

select
    cardnumber,
    CONCAT(
        @prefix,
        left(cardnumber, 2),
        MID(cardnumber, 3, 2),
        @offset + CAST(right(cardnumber, 2) as UNSIGNED INT)
    ) as university_id
from borrowers
