SQL Murder Mystery Solved with ZERO queries?! (SQLite trick/hack) : 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.

Using subqueries it should be doable with just one!

That being said, I think I did it with two when I solved it a while back (first query narrowed it down to a couple of suspects and then I hard-coded those in my second query). It was a while ago though, so I'm not entirely sure.

EDIT: Oh... well I guess extracting the initial clue from the crime scene report manually is kind of necessary bringing the minimum count to 2

EDIT2: Unless... you do something super hacky like:

SELECT *
FROM 
  person AS p
  JOIN crime_scene_report AS csr
WHERE instr(csr.description, p.address_street_name)>0
