Hello Jon,
I attended your RPG/DB2 seminars in the suburbs of Chicago. Although I live far from there now I grew up a few miles away from the hotel. It was convenient to visit family and save the company some $ by having my sister pick me up at the airport.
Yes, I successfully validated with JSONLINT. Copied the results out of the Run SQL Scripts result window.
This is what I pasted in:

The SQL JSON looked complex. I'll research that idea.
Thx

Subject: Re: JSON Error Message
Have you validated the JSON with something like JSONLINT ? I have found several times that I had invisible characters in the JSON that screwed it up.
It would also help if you showed the json and not just the DS.
Since you are already using SQL to access the JSON why use DATA-INTO and not just use the SQL abilities?

I'm working with our web team who is sending me a JSON document. After a simple proof of concept many months ago and test documents, I received the first real output from the web process.
After changing my DS to look more like the output of YAJLGEN, I'm
getting this error message out of YAJLINTO
1002: lexical error: invalid char in json text.█ The parser for the
DATA-INTO operation detected error code 1002.
The unprintable character displays on a green screen as a question mark. I don't see any unusual characters when viewing the JSON data using Run SQL Scripts or in debug.
Any suggestions about how to fix this? I tried filtering the JSON hoping to make sure that there's no unprintable characters under x'40'.
wrkContent = %ScanRpl(x'000102030405060708090A0B0C0D0E0F' +
'101112131415161718191A1B1C1D1E1F' +
'202122332425262728292A2B2C2D2E2F' +
'303132333435363738393A3B3C3D3E3F':
' ':wrkContent);
We're on 7.3. The web process inserts a record into a db2 file with a CLOB column. This is what the column definition looks like:
Transaction_Content FOR WTCONTENT CLOB ALLOCATE(100) CCSID 37
NOT NULL DEFAULT '' )
This is the JSOSN code from the program:
EXEC SQL DECLARE CWE100R0 CURSOR FOR
SELECT a.wtRecID, a.wtWebID, a.wtSts, a.wtStsDte, a.wtContent
FROM cvWebTx A
EXEC SQL FETCH NEXT FROM CWE100R0 INTO
:wtRecID, :wtWebID, :wtSts, :wtStsDte, :wrkContent;
Dcl-s wrkContent SQLTYPE(Clob:128000);
// Extract data from JSON document (cvWebTX.wtContent)
Data-Into txJSONDoc
%Data(wrkContent:'AllowExtra=Yes ' +
'doc=string ' +
'AllowMissing=Yes ' +
'Case=Convert ' +
'CountPrefix=Count_')
%Parser('YAJLINTO':'{"value_null":" "}');
Thanks in Advance
