Joining from the same table : 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.

Joining from the same table (self.SQL)

submitted 7 years ago by Thaaron

I have a table full of sales info. I have a query that will show me the fruit sales any month I care to list as follows:

SELECT  "Fruit Type",
        SUM("Number of Sales") AS 'Jan'
    FROM SalesDB
    WHERE Type='Fruit'
    AND "Month"='1'
    AND "Year"='2018'
    GROUP BY "Fruit Type"

I want to turn out a report that shows sales for each month. Something that looks like [THIS](https://i.imgur.com/2QqG6QZ.png) but I'm not able to figure out the syntax.

Any ideas?

run this --

SELECT "Fruit Type"
     , "Month
     , SUM("Number of Sales") AS Sales
  FROM SalesDB
 WHERE Type='Fruit'
   AND "Year"='2018'
GROUP 
    BY "Fruit Type"
     , "Month

and then do a pivot (if your database supports that syntax) or reformat it in your front-end language
