Re: Use SQL to retrieve 2 numerical amounts and the difference between them from one field

[Vern Hamberg <vhamberg@xxxxxxxxxxx>]

Hi Alan

I will assume there is always 1 space between the constants and the 
numbers. Also that the length of the constants is as you show here - 10. 
If those lengths are different, you'll just need to make a suitable 
adjustment. This should work -

with numbers as (select decimal(substr(field1, 12, locate(' ', field1, 
12) - 12)) as number1, decimal(substr(field1, locate('yyyyyyyyyy', 
field1) + 12)) as number2 from file1) select number1, number2, number2 - 
number1 from numbers

This also assumes that there is nothing after the second number.

Hope this is close!
