If my result rows are as follow:
ID Name Rate_Type
1 xxxx 9
2 zzzz 22
3 cccc 12
4 eeee 17
5 uuuu 90
Now how can I select the row with the rate type = 9 and any other row. I want my query to tell me if there is a row with Rate_type 9 and to give me also one row with ID <> 9
I want to have this result (only two row result):
ID Name Rate_Type
1 xxxx 9
! !!!! !--> This should be one additional row with Rate_Type <>9
You can do this with the union
of two queries. One that gets your rate_type = 9
, and one that gets your rate_type <> 9
(select * from t where rate_type = 9 order by rand() limit 1)
union all
(select * from t where rate_type <> 9 order by rand() limit 1);
