Re: Extract some numeric fields from a string

I would know that I want the "L=" or "M=" or whatever. Most of the time I
will want all the fields, but not necessarily. Extracting all at once
might be quicker, but extracting one at a time means I could create a more
generic routine that might one day be useful elsewhere.

The maximum length for each field is known, but the field could be shorter.

Jeff,

With SQL you could a combination of LOCATE, CAST nested in a rather complex
SQL statement.
Perhaps some layers of CTE may also be used (perhaps used recursively).

But I have some questions:

How do you make the selection to search for a value?
Is the length for each value known?

Given a 60 character string that looks like this (and there will be

trailing blanks):

L=19.3000A=19.43M=21.7700LS=19.93AS=19.93CB=19.1600

How would I extract the numeric data behind one of these character

interludes into a decimal field?

For example, one time I may want to know what's behind the "M=", another

time what's behind the "AS=", etc.

Wanting to know what's behind the "M=" means I want the value (in this

instance) of 21.7700 put into a decimal field.

Wanting to know what's behind the "AS=" means I want the value (in this

instance) of 19.93 put into a decimal field.

At one time or another I will want to know any one of the 6 "fields" in

that string. The fields are optional in the string, ie, the "CB=" may not

be there, in which case I want that field to default to 0.

V7R1. I have the SQL Development Kit if there is some slick way with SQL

to get one or all of these fields out of the string in one fell swoop.
