DELETE Problem

Hi Guys,

I have this strange problem. Take the following SQL i wrote which
erturns a list of dates lower than the one entered in a table :-

SELECT * FROM HACPRP.EQ_POOL_ACT_VIEW
WHERE ACTVTY_DT IN

(SELECT ACTVTY_DT FROM HACPRP.EQ_POOL_ACT_VIEW

WHERE SUBSTR(ACTVTY_DT,5,2) < '02'
)

UNION

SELECT * FROM HACPRP.EQ_POOL_ACT_VIEW
WHERE ACTVTY_DT IN

(SELECT ACTVTY_DT FROM HACPRP.EQ_POOL_ACT_VIEW

WHERE SUBSTR(ACTVTY_DT,1,2) < '03'
AND
SUBSTR(ACTVTY_DT,5,2) = '02'
)

UNION

SELECT * FROM HACPRP.EQ_POOL_ACT_VIEW
WHERE ACTVTY_DT IN

(SELECT ACTVTY_DT FROM HACPRP.EQ_POOL_ACT_VIEW

WHERE SUBSTR(ACTVTY_DT,3,2) < '27'
AND
SUBSTR(ACTVTY_DT,1,2) = '03'
AND
SUBSTR(ACTVTY_DT,5,2) = '02'
);

I had to do this in this format as whoever created the table made the ACTVTY_DT a CHAR(06) instead of a DATE !
This works fine and gives me back my required results.

The problem is however - How do I get SQL to delete these results now
from the HACPRP.EQ_POOL_ACT_VIEW table ?

No matter what i try it just falls over and will not delete the records.
Is it possible to do ?

I really need help on this one, so any comments would be really appreciated.

Peter.just replace the select * with the word DELETE, most likely cannot do the UNION DELETE so it most likely will have to be three seperate statements without the union.

let me know if that does not work|||Try this:

DELETE FROM HACPRP.EQ_POOL_ACT_VIEW
WHERE ACTVTY_DT IN
(SELECT ACTVTY_DT FROM HACPRP.EQ_POOL_ACT_VIEW
WHERE SUBSTR(ACTVTY_DT,5,2) < '02'
OR (SUBSTR(ACTVTY_DT,1,2) < '03'
AND SUBSTR(ACTVTY_DT,5,2) = '02')
OR (SUBSTR(ACTVTY_DT,3,2) < '27'
AND SUBSTR(ACTVTY_DT,1,2) = '03'
AND SUBSTR(ACTVTY_DT,5,2) = '02'));

also:

DELETE FROM HACPRP.EQ_POOL_ACT_VIEW
WHERE TO_DATE(ACTVTY_DT,'MMDDYY') < '27-MAR-2003';

;)|||hi,

or just type delete from ( <your query)

hope this helps
