Re: dataformatting in nodeJS SQL interface with IBM db2a -- WEB400

" I believe that it is problably a common problem"

Sounds like more reason for an RFE IMO.

Niels,

or as always "do it yourself" ;-)

Well I could raise a RFE but I believe that it is problably a common problem at least with non-trimmed fields so I have written this little 26 line function that iterates throug an object and clean up most.

I can foresee that the next question is "what about booleans?"

I also seems to remember that there are some column metadata send by db2a we just don't see them in the result set.

Maybee someone knows or has a link, it was in some example as far as I remember.

Niels,

Could you clarify? Are you suggesting that somebody submit an RFE to
have IBM add new SQL connection settings that implement the desired "trim"
behaviors?

At better solution would be: set the trim option on the connection
since that is already IBM proprietary . Doing it on the select
statement would pollute the sql syntax.

Why don't you raise a RFE for both trimming and sql-alike data types
in

the

result-set. I think my friend Jesse Gorzinsky would love that.

a lazy programmer (and I'm one) is a programmer that dosn't code
100 similar programs from one end to the other - they have fun
making a program generator that then does the job they do not
bother to make ;-)

Henrik,

The term "lazy programmer" is sometimes used with negative

connotation,

and

other times used with positive connotation. In this case, I
don't

fault

programmers who would rather not code the full SQL statement,

including

rtrim() function calls required to trim fields.

I was just trying to say that this is a case where invoking a
REST

web

service API would provide a simpler interface for programmers. A
web-service API would relieve programmers of the verbosity and

ofttimes

complexity of coding their own SQL statements.

I'm just suggesting that this is a case where a REST web service
API

would

have advantages over Node's db2a interface.

you may call it lazy to want to have a transparent interface
that

hasn't

to

be
touched every time you add a new or remove a column to a table.

Especially removing a column will cause errors if you specify

resultsets

by specific field names, imho they sould automatically be
removed

from

the rest service and that should automatically result in the
field

are

removed
in the UI regardless of code defining the field may exsist.

We are back to constructing an UI where if you filter the SSN
from

UserA

it dosn't appear in his UI but dons't filter it from UserB it

appears -

both running
on the same code.
