Question

I have a table in my database which has the following structure:

ID | Date | Ball1 | Ball2 | Ball3 | Ball4 | Ball5 | Ball6 | Ball7 | BonusBall

All the Ball rows are just integers.

What I want to do now is to write a select query that selects all the rows that have multiple of the same values in it.

For instance all the rows that contain 1 and 12.

I tried the following query, but that doesn't quite give my what I want:

SELECT * FROM number 
WHERE ball1 OR ball2 OR ball3 OR ball4 OR ball5 OR ball6 OR bonusball IN (1,12);

Am I on the right track? Any suggestions?

Answer 1

Your solution was already pretty good, but if you want to check it for each field, I believe you have to write it like this:

SELECT * FROM test
WHERE (ball1 = 1 OR ball2 = 1 OR ball3  = 1  
OR ball4  = 1 OR ball5 = 1 OR ball6  = 1 OR bonusball = 1)
AND (ball1 = 12 OR ball2 = 12 OR ball3 = 12  
OR ball4 = 12 OR ball5 = 12 OR ball6 = 12 OR bonusball = 12);

Although I would not advise running this query in a high traffic environment. A better idea would be to have two tables. One containing 'Lottery' and the other one 'Balls'. Where Balls would have a reference to the lottery table.

You should try to read up on Database normalization .

Answer 2

first of all - you should practice 'normalization'

second a better syntax would be

SELECT * 
FROM number 
WHERE ball1 in (1,12) 
OR ball2 in (1,12) 
OR ball3 in (1,12)
