Hello I am new to writing sql queries and am not sure how to write this up. Here is what I have so far:
--ISC Open RMA Report
SELECT
a.req_type,
a.request_id,
a.status,
b.return_reason
FROM
request a
join request_line b ON
a.request_id = b.request_id
WHERE
a.req_type = 'DEPO' and
a.status = 'OP' and
b.return_Reason in ('RR','EXCH')
So this is start but what I need it to do is take this informaton bring in open "RR" and "EXCH" currently. However what I really want the query to pull in is to show if this same serial id has been in or "OP" this same status within the last 60 days while the serial number is currently open with either the "RR" or the "EXCH" return reason.
Might not be clear but let me know if you can help. Thanks!

If you can't explain to another person how the code that you're copying from the internet works, then DON'T USE IT on a production system! After all, you will be the one supporting it!

This resembles another recent post:

http://qa.sqlservercentral.com/Forums/Topic998651-392-2.aspx?Highlight=Serial

Looks like you just have some added criteria with the need to consider status and return_reason. See if that link is a start for you.

Well I have been working on it more and still dont have the diagram sorry running into a problem with that. Let me show you where I am .....

--ISC Open RMA Report

SELECT

a.req_type,

a.request_id,

a.status,

b.return_reason,

c.serial_id,

d.event_dt,

d.event_type

FROM

request a

left outer join request_line b ON

a.request_id = b.request_id

left outer join request_product c ON

b.request_id = c.request_id

left outer join request_event d ON

c.request_id = d.request_id

WHERE

a.req_type = 'DEPO' and

a.status = 'OP' and

b.return_Reason in ('RR','EXCH') and

d.event_type = 'OPEN'

--event_dt > DATEADD(dd,-60,getdate())

ORDER BY

c.serial_id

The purpose of this report is to see if this serial number that is currently in for repair on an open ticket has been in repair within the last 60 days from the current date. So the query I currently have created has pulled all open serial numbers that are in for repair. However what I want it to report is to show only the serial numbers that are in for repair but have also been in for repair in the past 60 days. I do want it to report everything I have in the select statement. Just not sure how to get that last filter in there. I saw that other post and added it in as a comment in my WHERE statement just not sure how to use it?

Hi shwstpr8800~

In the hyperlink that I pasted on your thread, you can see that Derrick used a CTE (common table expression)... temporary result set which can be self-referencing. This is where he performed the date function. Please refer to the BOL for a better understanding of CTEs. Why don't you take exactly what he's provided and see if that part works for you. It worked like a charm for me, as I used it to find pieces of equipment that had been in for service more than once in the last 90 days. As the script is now, it doesn't care about status though.... just serial numbers that have been affected more than once in the last 60 days.

Good luck.
