What's Wrong?

使用 VARIANT 字段存储 map 数据，查询时如果字段没有所查询的子列，会报异常。比如我下面这个表的数据

其中最后一列Tags字段是 VARIANT 类型，tags中的键值对是由业务无脑写入，无法提前预设，可能为空，可能不一致。
使用 SELECT * from LogChunk_1 where Tags['tag_key1'] is not null and CAST(tags['tag_key1'] as text) MATCH_ANY 'tag_val1' order by Time DESC limit 10 查询便会报如下 `SQL 错误

errCode = 2, detailMessage = (172.16.56.137)[CANCELLED]failed to initialize storage reader. tablet=17136, res=[INTERNAL_ERROR]Not found field_name, field_name:Tags.tag_key1, schema:[Thread(8), Tags(9), Source(5), tags.tag_key1(-1), Title(6), Level(3), Time(2), CreateDate(1), Message(7), IP(4), AppId(0)]

What You Expected?

希望查询时能过滤掉没有对应子列的数据，而不是直接报错

先CAST(tags['tag_key1'] as text) -> CAST(Tags['tag_key1'] as text) 试试， 是个bug
