How to make MySQL SELECT from two tables and UNION?
Here is a situation:
I have two tables (tblA and tblB). tblA has a match_id that matches a
match_id in tblB. I want to run a query that returns the results of tblA
and tblB, and also the count of tblA records that don’t match any
tblB record.
I think this makes sense?
I have tried to query this, but I am having a hard time figuring out the
SQL correctly.
Is it something like this:
SELECT tblA.*, tblB.*, COUNT(*) AS no_matching
FROM tblA, tblB
WHERE tblA.match_id = tblB.match_id
UNION
SELECT tblA.*, tblB.*
FROM tblA, tblB
WHERE tblA.match_id <> tblB.match_id;
I think this is wrong (because SQL doesn’t support multiple UNIONs), but
if it’s correct, and you help me fix it, I will be very thankful.
A:
If I understand you correctly, you want something like this:
SELECT
tblA.a_col, tblA.a_col + tblB.b_col,
COUNT(*) AS matching
FROM tblA, tblB
WHERE tblA.match_id = tblB.match_id
GROUP BY tblA.a_col
UNION
SELECT
tblA.a_col, tblA.a_col + tblB.b_col,
COUNT(*)
FROM tblA, tblB
WHERE tblA.match_id <> tblB.match_id
GROUP BY tblA.a_col
