I have a query that looks like this:

SELECT
B.Company,
COUNT(*) AS QTY
FROM Table1 A
INNER JOIN Table2 B
ON A.CompanySk = B.EDWCompanySK
WHERE A.StartedDate >= '20171128'
GROUP BY B.Company
ORDER BY QTY DESC 

However, there is a field name "Ticket" in table1 that has duplicate values, that I need to exclude. How can I return the count with excluding duplicate "ticket" values.

  • Can table1.Ticket be NULL? – Denis Rubashkin Dec 4 '18 at 13:09
  • There are zero NULL values in Table1.Ticket – Ethan Heidtman Dec 4 '18 at 13:11
  • Use COUNT(DISTINCT Table1.Ticket) – Akina Dec 4 '18 at 13:13

Use the next query

SELECT
B.Company,
COUNT(DISTINCT A.Ticket) AS QTY
FROM Table1 A
INNER JOIN Table2 B
ON A.CompanySk = B.EDWCompanySK
WHERE A.StartedDate >= '20171128'
GROUP BY B.Company
ORDER BY QTY DESC
  • It is returning the error: "The multi-part identifier Table1.Ticket could not be bound." – Ethan Heidtman Dec 4 '18 at 13:20
  • I've corrected my answer – Denis Rubashkin Dec 4 '18 at 13:22
