QUESTION
Context
We're trying to built a database-application that can help first-year students prepare for their SQL-exam by assessing if a SQL-statement is a solution for the given question. The basic version simply checks if the given answer exists in the database as a known correct answer, if not it is sent to the teacher who then adds it to the database or discards it. In the next iteration we would like the application to asses answers more in the way it's done at exams, so you can still get some points even if parts of your query/statement are wrong.
Goal
To get this done we need to be able to 'break up' a statement.
For example, the answer:

QUESTION
My aim is to parse SQL (specifically Hive) statements with javascript, preferably Nodejs. I started out with node-sql-parser which looked promising. However I found quite a few cases where the parser did not recognize valid SQL like several nested functions on a column in a select clause, and multiple AND clauses in SQL that had lots of joins, unions, etc. (I've logged as issue but it will take some time).
I decided to look at Antlr v4. I followed the getting started steps with Hive SQL grammar. (https://github.com/apache/hive/blob/master/hplsql/src/main/antlr4/org/apache/hive/hplsql/Hplsql.g4); I generated parsers lexers and listeners using Antlr's generation for JavaSCript - all good so far. Then I tried a simple test as below:

Answered 2020-Nov-23 at 15:49As mentioned in the comments by kaby76: the grammar contains target specific (Java) code. You need to replace all Java code between {
and }?
with TypeScipt code.
