I knew this was coming.. lol.
I need to be more granular. I need to control how many elements are in each json file and name the files accordingly. This isn't a case where the app is responding to a web service. Rather, creating JSON data files for a batch process to get data into another system.
The job below is easy with native access, but becomes difficult when using SQL.

Why would you not just use SQL to create the JSON directly?

Subject: YAJLDTAGEN with SQL into DS
So I have a working application where I've used SQL data access to load a Data structure.
dcl-ds Customers qualified dim(50) inz;
addr_line1 varchar(40) inz('');
addr_line2 varchar(40) inz('');
city varchar(40) inz('');
state varchar(3) inz('');
zip varchar(10) inz('');
phone varchar(22) inz('');
email varchar(50) inz('');
end-ds;
I then use YAJLDTAGEN to create the JSON file:
DATA-GEN %SUBARR(customers:1:sqlRows)
%DATA(inStmf: 'doc=file output=clear')
%GEN('YAJLDTAGEN');
Output looks like this:
[
{
"addr_line1": "64a N Williams St",
"addr_line2": "",
"city": "Crystal Lake",
"state": "IL",
"zip": "60014",
"phone": "7792204179",
"email": "marvinstoys@xxxxxxxxx"
},
{
"addr_line1": "267 Main St",
"addr_line2": "",
"city": "Huntington",
"state": "NY",
"zip": "11743",
"phone": "6315498743",
"email": "lsdolls@xxxxxxx"
}
]
The endpoint has asked for this:
{
"Customers": [
{
"addr_line1": "64a N Williams St",
"addr_line2": "",
"city": "Crystal Lake",
"state": "IL",
"zip": "60014",
"phone": "7792204179",
"email": "marvinstoys@xxxxxxxxx"
},
{
"addr_line1": "267 Main St",
"addr_line2": "",
"city": "Huntington",
"state": "NY",
"zip": "11743",
"phone": "6315498743",
"email": "lsdolls@xxxxxxx"
}
]
}
I know how to create the DS... but then I'm not sure how to do Exec SQL INTO that DS.
I'm pretty sure the "into variable" cannot be "json.Customers".
What am I missing?
TIA,
Greg
