Question

given these table Players

| id |   name   |
+----+----------+
| 1  |  tawing  |
| 2  |  master  |
| 3  |  pepe    |
| 4  |  bethel  |
| 5  |  richard |

matches : tawing vs master master vs pepe master vs bethel master vs richard....

Here's what I've tried so far

select t1.id
       , t1.name 
from Players t1 
cross apply Players t2

Answer 1

Is this what you are looking for:

select concat(t1.name ,' vs ',  t2.name) "Match-up"
from players t1 
cross join players t2
where t1.name <> t2.name;
