ok very very much thanks
Your last touch to perfection
I changed to better explain the first column; instead of letters I used
numbers
after sort I have
1
1
2
3
3
4
4
5
5
6
7
8
1 100
1 100
2 y
4 y
5 y
5 100
7 100
ok 100 and y are bottom; but are mixed, or better they are ordered (col 1)
is possible have separated ? y first or after 100
example y first of 100
6
7
8
2 y
4 y
5 y
1 100
1 100
5 100
7 100
____
other last two questions in sql is better use OR or || or is same?
and col01 <= col02
in this case
col01 col02
null or void filed <= 10
I noticed that condition isn't verified (for me ok if so) but is always so
for sql? col 01 if haven't a value isn't considered minor of a number?
