RE: sql select count(*) and join

I use a CTE for this, Jim.

WITH T1 AS SELECT DISTINCT HORD
FROM HEADER A JOIN DETAIL B ON HORD=ORD
WHERE (your conditions)
SELECT COUNT(*) FROM T1

Joe

From: Jim Franz

Just not getting it....
Need several counts between a header & detail file
1. SELECT count(*) FROM header a join detail b on hord=dord WHERE
a.xxx <> 0 and a.yyy=0
This is counting the detail records.... I need header counts.

2. SELECT count(*) FROM header a join detail b on hord=dord WHERE
a.xxx <> 0 and sum(b.a + b.b + b.c) <>0
This is counting the detail records.... I need header counts.

Appreciate any pointers. The 3 SQL books I have are useless in examples
for this.
