Hi,
I have a large json string stored in SQL DB. table in SQL has 2 fields [ ID BIGINT, jsonFld NVARCHAR(MAX)]
If i used below command, I only get partial string back from SQL.
tSQL='SELECT ID, jsonFld FROM DBtable WHERE ID=1';
ttxt = connDB.fetch( tSQL);
If I used below, I can retrieve more text but still not complete.
tSQL='SELECT ID, jsonFld= CAST( jsonFld AS TEXT) FROM DBtable WHERE ID=1';
ttxt = connDB.fetch( tSQL); % The length( ttxt.jsonFld) is 9999999.
any suggestion on what I can do to receive full NVARCHAR(MAX) string back from SQL?
Thanks,
