sql - Joining tables in a database using differently formated data (MAC addresses) -

-

i have 2 tables i'd join via mac address field, each table stores mac addresses different:

table 1 data: 0:1e:8:c5:9e:fe table 2 data: 00:1e:08:c5:9e:fe

the first 1 removes starting 0's of 6 groups of colon-separated fields.

is there way can join on these in sql without having modify data?

i'm guessing have convert both values xx:xx:xx:xx:xx:xx, compare them...i'm not quite sure how that.

you can remove leading zeroes replace , stuff functions:

select * table1 inner join table2 on table1.shortmac = stuff(replace(':' + table2.longmac, ':0', ':'), 1, 1, '')
