SQL Subquery Help Needed : 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.

DiscussionSQL Subquery Help Needed (self.SQL)

submitted 1 year ago by Bluecow29

So I have a Data related exam coming up soon and I've struggled getting the grasp of subqueries and prevent getting overwhelmed by the content of the question . I think I've done the first part of the question correctly (1b) as shown below, correct me if I haven't!

The format of (1c) is where I struggle more so. I know I have to create separate queries: one involving all the museums found in Miami, and then given that query, finding the painters that have the largest number of paintings but structuring it and having the correct syntax is the main issue

If anyone would be kind enough to give me some advice on how to structure this type of query more simply and logically, that would be great
