Re: Node.js result set question - Trimming blanks

Simplified even more. :) I'm sure I'll put something together on
fieldexit.com for this so it's easier to follow.

[mymodules]

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

return row;
}

module.exports = {
trimRow: trimRow
}
------------------------

[main app]

var myStuff = require('mymodules');
....

do {
var rc = db.fetch(function callback(row) {
rs.push(myStuff.trimRow(row));
});
} while(rc != db.SQL_NO_DATA_FOUND);

Also found an easier way to trim the values (I think).. lol

do {
var rc = db.fetch(function callback(row) {
for (var i=0; i < Object.keys(row).length; i++) {
var key = Object.keys(row)[i];
console.log(key);
row[key] = row[key].trimRight();
}

rs.push(row);
});
} while(rc != db.SQL_NO_DATA_FOUND);

Adds a lot of processing time, though, I bet.

Here's what I ended up with.. not as bad as I thought:

db.init();
db.conn(DBname);
db.prepare(sql);
db.bindParam([
['%' + email + '%', db.SQL_PARAM_INPUT, 0],
]);

db.execute();

var rs = [];

do {
var rc = db.fetch(function callback(row) {
rs.push(row);
});
} while(rc != db.SQL_NO_DATA_FOUND);

res.render('customerList', {customerList: rs});

that's what I thought... thanks, Aaron. I'm used to my eRPG templates
where you can call them multiple times.

I guess I'd need to build the array/result set myself.

I am not sure you can call out to a Jade template multiple times. Or
rather, I've not done it that way so I can't speak to that approach.

Ok, so I wasn't going crazy. :)

I will try to remember to make a comment. But, here's a "theory"

question.

would it be better for me to take each row from the result and build

the

result set in node (as a whole, like exec() returns) and pass that

entire

result set to my jade template, or loop in node and write out the

data one

row at a time to my jade template that way.

Is there a "standard" for this type of processing?

be better (and more efficient) to get the entire result set. I

would

make

a comment on the bottom of that documentation page. IBM has been

doing

good at collaborating with the community on developerWorks (which,

in my

opinion, makes progress happen a lot faster than doing PMRs or

DCRs).

If I'm reading the docs correctly:

1.3.15. execute

*Description:*

Runs a statement that was successfully prepared using *prepare*()

once

or

multiple times. The statement is processed with the current

values of

any

application variables that were bound to parameter markers by
*bindParam*().

*Syntax 1:*

execute()

*Syntax 2:*

execute(function *Callback*(*OutParamList*))

*Parameters **Callback*(*OutParamList*):

*Callback *is a callback function to process the output

parameters of

the

parameter markers. *OutParamList *is a list of the output

parameters.

It

is

in the java script array format.

*Comments:*

* If the statement also return a result set, user can issue the

fetch()

function to retrieve the data row by row.


I believe This is saying that when using execute on a prepared

statement

vs

exec on an SQL statement the rows NEEDS be processed one at a

time.

bummer.. returning the entire result set made things so easy to

throw

into

a jade template. :) Now I'm going to need to change how that's

done. I

was wondering what was better practice, looping your result set

records

in

the node.js or letting your template handle it...
