Enhance the Prestodb python client to handle semicolon at the end of query

Open ArinMathew opened this issue 1 year ago • 0 comments

When we try a query like Select * from customer LIMIT 1; it returns error. It would have been better if we can handle from python client to process queries with and without semicolon so that it will not through any error.

Please find the error log attached below
