Re: json_table(httpgetclob, nested array

Hello Booth .

For reading multiple elements in array , you need to declare cursor and
read the input string.

Please find below example and it works for me .

Input - {"JSON_Exc":[{"abc":12963,"abc1":test},
{"abc":12964,"abc1":test2}]}

Sqlrpgle code.
exec SQL

declare list_Exception_Cursor insensitive scroll cursor for

select *

from JSON_TABLE(:json, '$.JSON_Exc[*]'

COLUMNS(

abc INTEGER PATH '$.abc',
abc1 CHAR PATH '$.abc1')

Then use fetch for cursor.

Thanks
Anshul

formatted:

wData_length 14
SeasOceans
0 "Adriatic Sea"
1 "Arctic Ocean"
2 "Atlantic Ocean"
3 "Bay of Bengal"
4 "Caribbean Sea"


The array is 100 elements, of which only 14 have data.

What does the JSON look like Booth? Kinda hard to map without knowing

what it looks like.

I am consuming json data with a numeric field and with a 100-element

array. I get the numeric field OK but the array fails. It looks like I
need to use "nested" but every way I have tried to use it fails.

exec sql select "SeasOceans" into :wSeas
from json_table(systools.httpgetclob(:wURL, ''), '$'
columns(
nested '$.Oceans[*]'
columns("SeasOceans" varchar(20) ) ) error on error

);

I am using an SQLRPGLE program for this and asked about this last week

on the RPG list with no response.
