Here's what it's reporting for the lengths:

ITITEM=7
ITIDESC=8
ITPRICE=8
ITQTY=6

The Node.js developer confirmed my suspicion that fieldWidth is returning
the length of the column name (plus a null terminator). It really returns
the *actual* length of the column name in case of truncation. I question
why this might be useful to a Node.js developer, since I would have
suspected that the node db adapter would never truncate the column name.

Interesting. I question why this might be useful to ANY developer,
because, really, who ever needs to know the length of the field NAME?
At least, when would you ever want to know the length of the (full,
untruncated) name, but NOT want the (full, untruncated) name itself?

fieldPrecise will return the precision (total column width) and fieldScale
(digits after the decimal) will return the scale.

So for the table in question,
ITITEM should return scale = 15, precision = 0
ITIDESC should return scale = 30, precision = 0
ITPRICE should return scale = 9, precision = 2
ITQTY should return scale = 9, precision = 0

I guess you meant precision = 15, scale = 0 for ITITEM, etc.
