    Better output of JDBC Interpreter.

    ### What is this PR for?
    Currently, the output format of the JDBC Interpreter is the table format 
with all the results except EXPLAIN statement, It is better for the user 
experience to output only the result of the SELECT statement in table format.
    This PR fixes the above issue and did some code refactoring.
    Tested on mysql and aws athena.
