Dynamic queries having tokens in square brackets

Describe the bug SQL statements which have tokens as part of the query end up in error.

To Reproduce Steps to reproduce the behavior:

1. Example SQL select spr.column_1, spr.column_2, spr.column_3, spr.column_4, spr.column_5, spr.column_6 from spr_table spr where spr.column_1 > 0 and [WHERECLAUSE]

2. Exception

Expected behavior The parser should attempt to fetch/extract/parse as much details as possible. In the above example, DML operation and the table name could have been extracted.

System

• Database = ORACLE
• Java Version = 1.8
• JSqlParser version = tested with 3.1 & 3.2

So can we close this?

Those queries with this query tokens are indeed incorrect from JSqlParsers perspective, because to this parser it is all SQL. Therefore it interprets those bracket parts like I described above. First you should replace those parts with a valid SQL and then send it through JSqlParser.
