that seems pretty hard to believe. what version of hive are you using?

This seems to work just fine in other SQLs, but doesn't seem work in hive.

I need to have several wild card characters in my 'like' clause as follows.

In other SQLs, I want:  ....  where page_url_query like '%?icid=main%dl%'

But in Hive that doesn't match.  I have several work arounds.  I can write it as:

 where (page_url_query like '%?icid=main%')  and (page_url_query like '%dl%')

or, I can just use something like where length(regexp_extract(page__url_query, '.*\?cdid-main.*dl.*',0)
<> 0

But more important is two or more '%' wild cards in a Hive like expression a known issue?
