Ok, I have some numeric columns, and I want to establish and average for them.
col 1 value = 4
col 2 value = 7
col 3 value = 3
col 4 value = 9
I want to be able to create (4+7+3+9)/4, as another column in a query. Then I want to use this number as for ORDER BY for another table.
With the numbers table there is another column that has an id relating to this other table.
I really can't get my head around this. It's hard enough to explain. Let me know if you need more help in explaining.
