hive中的錯誤(missing EOF at )

來源:互聯網
上載者:User

select cid as c from daily_conn where cid not in (select c from top_channel_log where v<>'5.8.7'  and (objlabel='1' or objlabel is null or objlabel='13557')) and v<>'5.8.7' ;

這條語句執行時出現了下面這條錯誤

Error: Error while compiling statement: FAILED: SemanticException [Error 10249]: Line 1:38 Unsupported SubQuery Expression 'cid': Correlating expression cannot contain unqualified column references. (state=42000,code=10249)

找了好半天,甚至改寫了sql,變成如下形式

select cid from daily_conn where v<>'5.8.7' except (select c from top_channel_log where v<>'5.8.7'  and (objlabel=1 or objlabel is null or objlabel=13557)) as b;

Error: Error while compiling statement: FAILED: ParseException line 1:86 missing EOF at 'except' near '20170425' (state=42000,code=40000)
出現了這樣的錯誤,最終改成了

select cid from daily_conn left outer join top_channel_log on daily_conn.cid=top_channel_log.c where daily_conn.v<>'5.8.7' and daily_conn.p_date>=20170423 and daily_conn.p_date<=20170425 and top_channel_log.v<>'5.8.7' and (top_channel_log.objlabel=1 or top_channel_log.objlabel is null or top_channel_log.objlabel=13557);

造成這樣的原因是:本人使用的是hive1.3的版本,1.3的版本中支援not in 但是不支援not in的子查詢;不支援except的使用。
