Re: Weird IWS Bug (?)

As you'll see from my earlier post Anshul, this (apart from name) is exactly what I have.

There is no requirement for the _LENGTH to be a 10I though is there?

HI Martin

I have followed Nadir's example and attaching the same code snippet as well



P getAll B EXPORT

D getAll PI

D students_...

D LENGTH 10i 0

D students likeds(studentRec) dim(1000)

D options(*varsize)

D httpStatus 10i 0

D httpHeaders 100a dim(10)

/FREE

clear httpHeaders;

clear students;

students_LENGTH = 0;



openStudentDB();



setll *loval STUDENTDB;

read(e) studentR;

if (%ERROR);

httpStatus = H_SERVERERROR;

return;

endif;



dow (NOT %eof);

students_LENGTH = students_LENGTH+1;

students(students_LENGTH).studentID = studentID;

students(students_LENGTH).firstName = firstName;

students(students_LENGTH).lastName = lastName;

students(students_LENGTH).gender = gender;



read(e) studentR;

if (%ERROR);

httpStatus = H_SERVERERROR;

return;

endif;

enddo;



httpStatus = H_OK;

httpHeaders(1) = 'Cache-Control: no-cache, no-store';



closeStudentDB();

/END-FREE
P getAll E


"STUDENTS_LENGTH": 5,
"STUDENTS": [
{
"STUDENT1": {
"STUDENTID": "ty3411",
"FIRSTNAME": "test3",
"LASTNAME": "test2",
"GENDER": "male"
},
{
"STUDENT1": {
"STUDENTID": "ty3433",
"FIRSTNAME": "test3",
"LASTNAME": "test2",
"GENDER": "male"
},

{
"STUDENT1": {
"STUDENTID": "ty3456",
"FIRSTNAME": "test1",
"LASTNAME": "test2",

},

{
"STUDENT1": {

{
"STUDENT1": {

"FIRSTNAME": "test1",
"LASTNAME": "test2",
"GENDER": "male"
}
}
]


There are 5 records in database only. This works like a charm . It helps
in performance and resources as well.

Hope it helps

Thanks

huh? This is totally new to me... Let me say it back...

So, if this time there are 3 rows of data then I will get 3. If there
are 9 rows, I will get 9 and only 9?

I would very much like to see an example of that.

So to avoid that issue of populating blank values . We use the concept
Nadir/Martin pointed out in which we will have two output prams length

and

datastructure . When you are deploying yhe webservices , please uncheck

the

detect field length. Then you will have option with length of 20 and in
drop down you can use length for dim.a

Benefit of using it is you will have now 3 rows not 20 and you will have
one more output called length,

{
"XXX_DS": [
{ first datastructure row },
{ second datastructure row},
{third datastructure row } ]
"length":3 }

Without Length concept
