Re: [SQL] locked my keys in the car

Rich, Dave, Federico ---

Guys, for the assist! The last piece of the puzzle follows.
A buddy of mine in Pennsylvania was able to force the date comparison.
Rich, this is pretty close to your code, a couple of minor diffs
do the job!

SELECT tr_id, tr_date
FROM crtrd1 ALIAS1
WHERE ALIAS1.tr_unit = 'SMA'
AND (ALIAS1.tr_type = 'A' OR ALIAS1.tr_type = 'I')
AND NOT EXISTS(
SELECT tr_id
FROM crtrd1 ALIAS2
WHERE ALIAS2.tr_unit = 'SMA'
AND ALIAS2.tr_id = ALIAS1.tr_id
AND (ALIAS2.tr_type = 'T' OR ALIAS2.tr_type = 'O')
AND ALIAS2.tr_date > ALIAS1.tr_date
)
ORDER BY tr_date DESC;

Thanks for your assistance boys - I'm thinking of getting this
tattooed somewhere - somewhere I can see it when I need it that is!
