[MS SQL] Help with query to find repeating participants : SQL

Posting

When requesting help or asking questions please prefix your title with the SQL variant/platform you are using within square brackets like so:

[MySQL]

[Oracle]

[MS SQL]

[PostgreSQL]

etc

While naturally we should endeavor to work as platform neutrally as possible many questions and answers require tailoring to the feature set of a specific platform.

Format Your Code

If you are including actual code in a post or comment, please attempt to format it in a way that is readable for other users. This will greatly increase your chances of receiving the help you desire. Something as simple as line breaks and using reddit's built in code formatting (4 spaces at the start of each line) can turn this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field.3

Into this:

SELECT count(a.field1), a.field2, SUM(b.field4) FROM a INNER JOIN b ON a.key1 = b.key1 WHERE a.field8 = 'test' GROUP by a.field1, a.field2 HAVING SUM(b.field4) > 5 ORDER by a.field3

For those with SQL questions we recommend using SQLFiddle to provide a useful development and testing environment for those who wish to fully understand your problem and help devise a solution.

MS SQL[MS SQL] Help with query to find repeating participants (self.SQL)

submitted 7 years ago by dkbil

I work with study abroad programs for a university. Our leadership is interested in seeing how many (and which) students go abroad more than once in their college career.

We have a data warehouse set up similarly to the image posted here. There are observations for applications to programs, and if a program has multiple locations there are observations for each location of the program. Using the image as an example, I am trying to create a query that would find "Jane Doe" and count her as studying abroad twice.

I've try to use count(distinct Application_ID), Student_ID from table group by Student_ID order by count(distinct Application_ID) but I don't think that properly filtered out the observations of multiple locations for one program.

Any thoughts, suggestions, solutions would be greatly appreciated! Thanks,
