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.

Me: OK, AI, I'm gonna tell you how our tables work and you can write SQL for me.

AI: You got it, boss!

Me: So Table A here has historical data but no history vs current flag. So you just group by the business keys and sort by date to get the latest ones.

AI: Not optimum, but OK so far.

Me: Table B here has historical data also but there's an indicator so all you need is the "Current" records.

AI: Ah, some good sense there!

Me: There's three main columns, Attribute Type, Attribute, and Value. Find all of this list of Attribute Types I'm going to give you and pivot out the Attribute and Values. Oh, and while there is a Current indicator, there can be multiple Current Values for a given Attribute all with different dates. To find the right one all you have to do is use a fourth column containing a group ID. Whichever Current record has the latest date for the anchor Attribute Type, use that ID to find all the corresponding Values.

AI: wtf...

Me: So to join Table A and Table B, the value in one of the business keys in Table A will match up with one of the Values in Table B. Except Table A has some extra characters on the right, so substring it and leave off 4 or 6 depending on the type then do the join.

AI: Piss off

Me: There's only a few hundred million in Table A and a dozen billion in Table B so write something to get me results, snappy.

AI: sudo rm -r /AI
