Question

I have a table that consists of
id (auto_increment)
number int (can contain values from 10 to 12)
myvalue (varchar)

What I want to do is disperse the relational structure of this table for report purpose. I.e , I´d like to have something like:

id (auto_increment)

number10 (containing myvalue WHERE number=10)

number11 (containing myvalue WHERE number=11)

number12 (containing myvalue WHERE number=12)

I know that I can get the respective results by
SELECT myvalue FROM mytable WHERE number = 10;

but I haven´t figured out how to write these three SELECT statements into one single table or view.

thx for any help in advance!

This might do what you need. You’ve not explained it very well though so it might not!

SELECT user,
MIN(CASE WHEN number = 10 then myvalue end) AS number10,
MIN(CASE WHEN number = 11 then myvalue end) AS number11,
MIN(CASE WHEN number = 12 then myvalue end) AS number12
FROM table
WHERE number IN (10,11,12)
GROUP BY user
