Description

PostgreSQL query

SELECT * FROM "
(
    (
      (S.C c INNER JOIN S.N n ON n.id = c.id)
      INNER JOIN S.A a ON (NOT a.isactive)
    ) INNER JOIN S.T t ON t.id = a.id
)

Reproduction code

import static org.apache.calcite.sql.parser.SqlParser.configBuilder;

import org.apache.calcite.sql.parser.SqlParseException;
import org.apache.calcite.sql.parser.SqlParser.Config;
import org.apache.calcite.sql.parser.babel.SqlBabelParserImpl;
import org.apache.calcite.sql.validate.SqlConformanceEnum;
import org.apache.calcite.tools.FrameworkConfig;
import org.apache.calcite.tools.Frameworks;
import org.apache.calcite.tools.Planner;

public class Test {
    public static void main(String[] args) throws SqlParseException {
        Config parserConfig = configBuilder().setConformance(SqlConformanceEnum.BABEL).setParserFactory(SqlBabelParserImpl.FACTORY).build();

        FrameworkConfig frameworkConfig = Frameworks.newConfigBuilder().parserConfig(parserConfig).build();

        Planner planner = Frameworks.getPlanner(frameworkConfig);
        planner.parse("SELECT * FROM (((S.C c INNER JOIN S.N n ON n.id = c.id) INNER JOIN S.A a ON (NOT a.isactive)) INNER JOIN S.T t ON t.id = a.id)");
    }
}
