Description

Currently, SQLAnalyzer only prints exact error line and message for the most outer query. In other words, it does not handle the error inner subqueries.

In many cases, query statements can be tens of lines to hundreds of lines. In this case, it is very hard to find what the problem is.

The main objective of this issue is to print the exact error line. It would be greater if error message includes some supplementary messages to help user find the cause of errors.
