[Koha] SQL help - Bulk Card Number modification

[Radek Šiman]

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
