  • 0

I know about the RAND() function in SQL to select random rows from a table, but the problem is I don’t want it selecting different random rows each time I refresh the browser. I want the same set of random rows, which is selected based on a key.

For example, say this is my table:

----------------------
| id | word | literal|
----------------------
|  1 | say  |   YAS  |
----------------------
|  2 | eat  |   TAE  |
----------------------
|  3 | hit  |   TIH  |
----------------------
|  4 | bad  |   DAB  |
----------------------
|  5 |delve | EVLED  |
----------------------

maybe if the key was 6, it would select rows 4 & 5 every time. But maybe if the key was 3, it would select rows 2 and 5. So it would select a set of random rows each time based on a key.

Is this possible?

    You can use the : Rand(N) form of the MySQL function and take care to pass the same N each time you want the same sequence of generated random numbers. The N could stay the same during a specific session or it could be stored in a cookie for use over a longer period. It depends on how long you need the sequence to remain the same.
