Here is a table "table1" with a char(5) column "col1"
the value in col1 looks like this:
12345
23568
01235

the value of col consists of number
if I wanner get a char(5) result that every digit of this value
should be the max of the value of col at the same digit,how to?
I have thought this for about a week?Maybe it is a mission impossible?

I do not know what is what

Like this?


SELECT MAX(SUBSTRING(col1, 1, 1))
     + MAX(SUBSTRING(col1, 2, 1))
     + MAX(SUBSTRING(col1, 3, 1))
     + MAX(SUBSTRING(col1, 4, 1))
     + MAX(SUBSTRING(col1, 5, 1))
FROM table1

If you have values that are less then 5 characters long and you want to treat them as right-aligned, replace col1 in Arnold's statement with

(REPLICATE(' ', 5-LEN(col1))+col1)

to pad the value with spaces.
