Hi all. I am a newbie with SQL. Here is my question:
The table is like
col1 col2 col3
a1 1 c
a1 2 a
...
a1 100 t
a2 1 d
a2 2 c
...
a2 100 g
a3 1 h
...
a3 100 d
now I am trying to make a function. The parameters are 2 ints of col2(such
as 2,81). I want to return a table containing the composition of that two
input parameters which is like
for parameter (2,81)
dt 10%
ac 40%
tt 50%
could anyone help me out?
