sql output like:

id | value | data | v 3  | val1  | dat3 | 3 4  | val2  | dat4 | 1

thanks!

you need identify max value in subquery , join against constant element

fiddle

select *       table1          join     (select max(v) maxv, value table1 group value) t           on t.maxv = table1.v , t.value=table1.value
