Thanks Chris... I get that part of the puzzle.
What I'm missing is how to
Exec SQL
select addr1, addr2, city, state, zip
INTO :allcustomers.customers
From MYFILE.....
I'm pretty sure the INTO will not work.

Try:
dcl-ds AllCustomers qualified;
num_Customers uns(5);
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;
End-ds;
AllCustomers.num_Customers = sqlRows;
DATA-GEN AllCustomers
%DATA(inStmf: 'doc=file output=clear countprefix=num_')
%GEN('YAJLDTAGEN');
If that doesn't work with the SQL you can keep the other customers array and continue to load that with sql and then:
%Subarr( AllCustomers.Customers:1:SqlRows ) = %SUBARR(customers:1:sqlRows);
Then run the DATA-GEN.

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,
