The UDx cannot take input from more than 1 table at present. You can output a table with 1 col and 1 row with JSON formatted text. A VARCHAR can take strings of upto 65000 charaters. You might wat to use LONG VARCHAR for longer strings which can store upto 32,000,000 bytes.

Guys,
I am currently working on Vertica DB. Kindly let me know how to output the contents of a table in JSON format.
Best,
