Re: String to integer in SQL similar to atoi()

Dennis -

Wrap the SUBSTR's with a CAST to convert them to numeric, and I believe
you've got the problem solved.

Dennis,

I think you could do something like this:

*********
Select
Substr(foocol, 1, position(' ', foocol) - 1) as N1,
Substr(foocol, position(' ', foocol) + 1) as N2
FROM footab
*********

Not very sure about the exact syntax, as I'm not near a computer right now.

Hi, Folks:

I have a column (fooCol) in a table (footab) that contains string data
looking like the following:
'961 6'
'2809 6'
'67 6'
'66 6'
'2879 6'
'2874 6'

(No, the second set is not always 6. This is a column that was loaded
incorrectly due to lack of a comma at the source end, and I'm trying to
find
an efficient way to live with it (longer story)).

I have need of *efficiently* returning the first set of digits and the
second set of digits as separate numeric values, so that they may be used
in
an UPDATE or INSERT statement or embedded SQL where the result is numeric.

Any ideas? I thought of using something like select left(foocol, instr('
',
foocol)) (which is mySQL syntax) for the "left number", but I couldn't
find
an instr equivalent and, even if I did it'd still be a string value. The
second set would probably be a no-brainer after landing on a solution for
the first.

Thanks for any pointers.
