I came across some code today that has the following:
SELECT
.
.
.
WHERE
.
.
.
  AND p.refreshTimeStamp    = SOME
        (SELECT
                MAX(pa.refreshTimeStamp)
         FROM pymt pa
         WHERE compid = '12345666'

Can anyone tell me what the " = SOME" portion of the code does?  I've done
some research, but can't find anything so far.
