sql - Binary mask oracle -


i have sql command in sql-server, , need migrate oracle, there's part of sql don't understand how translate it. here's sql:

select * mytable id = @id , (mask & @mask) = @mask

i think it's binary mask, i'm not quite sure , don't know if can in oracle, me?

thank much

you correct - binary mask.

oracle provides bitand function, others (bitor, bitxor) must self made.

using bitand function select return value 2:

select bitand(6,2) dual;

so query in oracle can rewritten in following way:

select * mytable id = :id , bitand(mask, :mask) = :mask
