Select from multiple tables matching multiple criteria
I am working with 3 tables, trying to pull a list that match certain criteria. I need a list of companies from the companies table, that have an active opportunity (iactive is 1 in opportunities table) AND have a record in the notes table of type order or order2.
Companies Table
+------+------------------+
| cid | ccyname |
+------+------------------+
| 1c | Bobs Fish |
| 2c | Sheep Counters |
| 3c | Old Timers |
| 4c | Roasted Nuts |
+------+------------------+
Notes Table
+------+--------+--------+
| nid |ntype |cid |
+------+--------+--------+
| 1n | order |3c |
| 2n | quest |1c |
| 3n | order2 |2c |
| 4n | cancel |2c |
+------+--------+--------+

+------+--------+--------+
| oid |iactive | cid |
+------+--------+--------+
| 1o | 1 | 1c |
| 2o | 0 | 3c |
| 3o | 1 | 3c |
| 4o | 1 | 2c |
+------+--------+--------+
With this example the results should be:
Results
+----------------+--------+
| ccyname | oid |
+----------------+--------+
| Old Timers | 3o |
| Sheep Counters | 4o |
+----------------+--------+
Which would give me only companies that have both an active opportunity and an order or order2 note.
I have tried building this a few different ways, but I always end up with just one result or with too many. Could I get some help?
This is on SQL Server 2005.
Thanks, John
SELECT DISTINCT(ccyname), oid
FROM Companies AS c
INNER JOIN Notes AS n ON c.cid = n.cid
INNER JOIN Opportunities AS o ON c.cid = o.cid
WHERE n.ntype IN ('order','order2')
AND o.iactive = 1;
Caveat: Not Tested.
SELECT
C.ccyname, O.oid
FROM
Companies C
JOIN
Opportunities O AND O.cid = c.cid
WHERE
O.iactive = 1
AND
EXISTS (SELECT * FROM Notes N
WHERE N.ntype IN ('order', 'order2') AND N.cid = c.cid)
SELECT DISTINCT cid, ccyname
FROM Companies c
INNER JOIN Notes n ON n.cid = c.cid AND n.ntype = 'order2' OR n.ntype = 'order'
INNER JOIN Opportunities o ON o.cid = c.cid AND o.iactive = 1
