[alibaba/druid]visitor.getConditions()对于某些特殊的值无法解析

能否加上对这种语法的支持？

能提供完整SQL么？

select l_returnflag, l_linestatus, sum(l_quantity) as sum_qty, sum(l_extendedprice) as sum_base_price, sum(l_extendedprice (1 - l_discount)) as sum_disc_price, sum(l_extendedprice (1 - l_discount) (1 + l_tax)) as sum_charge, avg(l_quantity) as avg_qty, avg(l_extendedprice) as avg_price, avg(l_discount) as avg_disc, count() as count_order from lineitem where l_shipdate <= date '1998-12-01' - interval '103' day group by l_returnflag, l_linestatus order by l_returnflag, l_linestatus limit 1; 这个sql是tpch测试集的第一条sql，我想要通过visitor.getConditions().getvalues()来得到l_shipdate这一字段的查询条件，但是解析出来得到是null值，麻烦您解决
