Home -> Community -> Mailing Lists -> Oracle-L -> RE: Basic sql
thanks! Except now I'm worried about the accuracy:
1 select count(*)
2 from a
3 where (op_year, unit_id, 1 + floor(extract(month from
a.op_date)/4))
4 in (select b.year, unit_id, qtr 5 from b 6* where b.batch_table =3D 'UNT_HRLY')SQL> / COUNT(*)
38210
Elapsed: 00:00:01.03
SQL> ed
Wrote file afiedt.buf
1 SELECT COUNT(*) FROM a
2 WHERE EXISTS (SELECT *
3 FROM b
4 WHERE b.batch_table=3D'UNT_HRLY' 5 and a.unit_id =3D b.unit_id 6 and a.op_year =3D b.year
COUNT(*)
40762
Elapsed: 00:01:09.01
....none of the columns have NULL values after I filter table b on batch_table so I know there's nothing funky there.
I'm going to look at it some more but I don't see why the different row counts?

You can try this if you still want to use the case statement
SELECT COUNT(*) FROM a
WHERE EXISTS (SELECT *=3D3D20
FROM b
WHERE a.unit_id =3D3D b.unit_id
and a.op_year =3D3D b.op_year
and extract(month from a.op_date) BETWEEN
CASE
WHEN b.qtr =3D3D 1 THEN 1
WHEN b.qtr =3D3D 2 THEN 4=3D20
WHEN b.qtr =3D3D 3 THEN 7=3D20
WHEN b.qtr =3D3D 4 THEN 10=3D20
END
AND
CASE
WHEN b.qtr =3D3D 1 THEN 3
WHEN b.qtr =3D3D 2 THEN 6
WHEN b.qtr =3D3D 3 THEN 9
WHEN b.qtr =3D3D 4 THEN 12
END)

Well I've had my coffee and I still can't get this to work:
SELECT COUNT(*) FROM a
WHERE EXISTS (SELECT *=3D3D20
FROM b
WHERE a.unit_id =3D3D b.unit_id
and a.op_year =3D3D b.op_year
and extract(month from a.op_date) BETWEEN CASE
WHEN b.qtr =3D3D 1 THEN 1 AND 3
WHEN b.qtr =3D3D 2 THEN 4 AND 6
WHEN b.qtr =3D3D 3 THEN7 AND 9
WHEN b.qtr =3D3D 4 THEN 10 AND 12
END)
I've tried several variations of this (all that I can think of)i.e. quotes and parenthesis in all kinds of places, case to build entire last filter instead of just the '1 and 3' pieces. and it always returns:
ERROR at line 7:
ORA-00905: missing keyword
9.2 on windows
What simple thing am I missing now?
Thank you for the extra eyes!
