Hive中使用RLIKE时如何写模糊多子串匹配

Question

例如：

df.select('category').show()

+---------------------------+
|                   category|
+---------------------------+
|            money,insurance|
|            life, housework|
|           game,FPS,network|
|            game,fight,jump|
|                      hotel|
|                 trip,hotel|
|                       null|

我想使用 RLIKE 编写一个正则表达式来模糊匹配子字符串列表之一，['money', 'life']。

-- This is an exact match
SELECT * 
FROM tb_name
WHERE col_name RLIKE '(money|life)'

-- This is a fuzzy match
SELECT * 
FROM tb_name
WHERE col_name RLIKE '*.(money|life)'

但是模糊匹配代码段中的ast树有错误。

06-11 16:59:17-fatal filter ast tree

(TOK_QUERY (TOK_FROM (TOK_TABREF (TOK_TAB tb_name))) (TOK_INSERT (TOK_DESTINATION (TOK_DIR "hdfs://XXXX/XX")) (TOK_SELECT (TOK_SELEXPR TOK_ALLCOLREF)) (TOK_WHERE (RLIKE (TOK_TABLE_OR_COL col_name ) '*.(money|life)')) (TOK_LIMIT 2000)))

06-11 16:59:17-fatal Filter feature: .TOK_TAB \S tdw_inter_db.*|.TOK_(CUBE|ROLLUP) .

所以我看不出 模糊匹配 代码片段有什么问题。
那么有人可以帮助我吗？
提前致谢。

Answer 1

'(?i)money|life' 正则表达式将匹配包含任何 money、life 的字符串，不区分大小写 - (?i)
