young0098 · 2024-03-31T02:01:35Z

Always check against the Latest SNAPSHOT of JSQLParser and the Syntax Diagram

Failing SQL Feature:

parse timeout，just a common sql , haved set timeout argument to 3 minutes.
Example: WITH ROLLUP can't be parsed

Seems to be Google BigQuery.
Lucky you as I am going to implement this special FORMAT clause.

manticore-projects · 2024-03-31T02:54:55Z

I have implemented Google BigQuery CAST with FORMAT clause and in the result the query does not fail anymore after 1 minute.

Instead it literally runs forever, likely because of the way how you call FUNCTION (which depends on expensive semantic LOOKAHEAD amplifying when nested deeply).

I can only encourage you to write more reasonable SQL. e.g. instead of calling SUBSTR (TRIM(A1.CLOSE_TM), x) a million times, you could just Split() your string into characters and then access this array.

Unfortunately I don't have the time to dig deeper into this particular statement right now. You can try to remove logical blocks until it parses normally in order to isolate the particular logical block where it starts hanging. Once we get this analysis, we can certainly do something about in the Grammar.

Good luck.

Thanks. This is old code, I have to paser it. I change cast expression manually, delete format keywords. The timeout exception is remain. If I want to pasrse this query successfully, How many timeout I should set？
