Thanks for your reply.
Actually i was looking for something like ISNUMERIC. I just wanted to
pull out rows that contains only numbers and just eliminate the others
with chars in them.
Here is what i tried so far....
Select * from Mytable where ISNUMERIC(substring(COL2,2,10))
Assuming data field looks like this
COL2
A123X456
A45687E
I only want to do the check on portion of the string so i used
substring to take out the part i wanted to test against ISNUMERIC.
It shold work, but for some reason im getting an error msg. Any idea
what am i doing wrong here?
Thanks!
