Re: dataformatting in nodeJS SQL interface with IBM db2a

I wrote a set of nodejs functions that add this feature.. Not too
difficult at all.

trimming is trivial in node

for (var key in dataObject) {
keyCount++;
var dataValue = dataObject[key].trimRight();

.....

In fact, I use this to trim an entire row when returning a result set

function trimRow(row) {
for (i in row) {
row[i] = row[i].trimRight();
}

return row;
}

for (row in resultSet) {
trimRow(resultSet[row]);
}

I have a set of DB functions that encapsulate the IBM stuff, and this is
how I do it now... I just had to rewrite it for node6 and async so still
in testing, but this part still works.

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.
