Subject Invalid Table Alias
Date Sat, 21 Jul 2012 01:06:39 GMT
Whenever I am running the below query

(SELECT testingtable1.buyer_id, testingtable1.item_id,
testingtable1.created_time from (select user_id, prod_and_ts.product_id as
product_id, prod_and_ts.timestamps as timestamps from testingtable2 LATERAL
VIEW explode(purchased_item) exploded_table as prod_and_ts where
to_date(from_unixtime(cast(prod_and_ts.timestamps as BIGINT))) =
'2012-07-09') prod_and_ts RIGHT OUTER JOIN (SELECT buyer_id, item_id,
rank(buyer_id), created_time, UNIX_TIMESTAMP(created_time)
    SELECT buyer_id, item_id, created_time
    FROM testingtable1
where to_date(from_unixtime(cast(UNIX_TIMESTAMP(created_time) as int))) =
    DISTRIBUTE BY buyer_id
    SORT BY buyer_id, created_time desc
) a
WHERE rank(buyer_id) < 5) testingtable1 ON (testingtable1.item_id =
prod_and_ts.product_id AND testingtable1.BUYER_ID = prod_and_ts.USER_ID AND
testingtable1.created_time,FROM_UNIXTIME(cast(prod_and_ts.timestamps as
BIGINT)))) <= 15)* where prod_and_ts.product_id IS NULL ORDER BY
testingtable1.buyer_id, testingtable1.created_time desc) TT GROUP BY

I am getting below exception as - Its happening in red color in above query

*FAILED: Error in semantic analysis: line 10:157 Invalid Table Alias mi.*
But the same thing works fine in SQL Server. Anything wrong I am doing in
the red line? I am currently trying to see by that red line is if
difference between date is within 15 minutes.
