Grab all rows for a Records where a single instance occurs in a different row for the record - sql

Question

I have a query where I am looking into three different tables and for the purposes of this post I only need to see three columns; RecordID, FieldType and Tranid. The Record ID can have multiple Field types and each field type will have a distinct tranid.
What I am trying to do is grab all the entire set of data if any of the Field Types = 'CO'
SELECT
Header.RecordID,
Detail.FieldType,
Header.TranID
FROM Header
INNER JOIN (select * from Detail where fieldtype = 'CO') as Detail
ON Header.RecordID = Detail.RecordID
INNER JOIN TranDef ON Header.TranID = TranDef.TranID
WHERE
(Header.CalendarDate BETWEEN GETDATE() - 10 AND GETDATE())
But this is not working. I'm only getting one row of data back, where as I said, I want all the data for the record, not just the one row. What am I doing wrong here?

Answer 1

Your query does not work because it limits the rows selected from Detail to these with fieldtype = 'CO', and inner joins to it.
It looks like you are looking for a WHERE EXISTS query:
SELECT
h.RecordID,
d.FieldType,
h.TranID
FROM
Branch b
INNER JOIN
Header h ON b.BranchID = h.BranchID
INNER JOIN
Detail d ON h.RecordID = d.RecordID
WHERE (h.CalendarDate BETWEEN GETDATE() - 10 AND GETDATE())
AND EXISTS (
SELECT *
FROM Detail dd
WHERE dd.RecordID = h.RecordID AND dd.fieldtype = 'CO'
)
The idea is to join to all Detail records, and then filter the result based on existence or non-existence of 'CO' records among the Detail rows linked to the corresponding Header row.

You can try including the below in the WHERE criteria:
SELECT RecordID, FieldType, TranID
FROM Branch br, Header hr, Region rgn
WHERE br.FieldType = 'CO' and
hr.FieldType = 'CO' and
rgn.FieldType = 'CO'

I feel like your making this more complicated than it should be. Perhaps try the following? I know I've done similiar things in the past.
SELECT
h.RecordID,
d.FieldType,
h.TranID
FROM Header as h
INNER JOIN Branch as b on b.BranchID = h.BranchID
INNER JOIN Detail as d on d.RecordID = h.RecordID
WHERE
(h.CalendarDate BETWEEN GETDATE() - 10 AND GETDATE())
and d.fieldtype = 'CO'
