Question

I’ve got a table which contains week numbers and id’s

| id | week |
| 1  |  1   |
| 2  |  2   |
| 3  |  6   |
| 4  |  8   |

What I need to do is retrieve based on the value of week. But I also need to return the row more than once if the row is greater than a certain number.

For instance (pseudo),

if week > 2
and week > 6

| id | week |
| 2  |  2   |
| 3  |  6   |
| 3  |  6   |
| 4  |  8   |
| 4  |  8   |

ID 3 & ID 4 appear twice, because they’re greater than both 2 and 6. ID 2 will only appear once because it is only greater than 2.

Unfortunately looped queries are sort of out of the question as this query will be return 2k+ rows.

Any help will be greatly appreciated, even if the solution is PHP based.

Answer 1

Split the query into multiple queries and then merge the result using UNION.

The following should give you the result you want.

(SELECT * FROM yourTable WHERE week > 2)
UNION ALL
(SELECT * FROM yourTable WHERE week > 6)
