> Project: Apache Drill
> Issue Type: Improvement
> Components: Execution - Relational Operators
> Affects Versions: 0.6.0

> Priority: Major
> Fix For: Future

> Tableau is using the != (not equal) operator in the bellow query which failed
> tonight with Drill. This operator isn’t technically ANSI SQL, but almost all
> DBMS support it, any chance this support would be added?

> SELECT CASE
> WHEN `twitter_tweets`.`favorite_count` / 1 < 0
> AND `twitter_tweets`.`favorite_count` / 1 !=
> `twitter_tweets`.`favorite_count` / 1 THEN `twitter_tweets`.`favorite_count`
> / 1 - 1
> ELSE `twitter_tweets`.`favorite_count` / 1
> END AS `Favorite_Count__bin_`,
> COUNT(`twitter_tweets`.`favorite_count`) AS `cnt_favorite_count_ok`
> FROM `mfs.views`.`twitter_tweets` `twitter_tweets`
> INNER JOIN `mfs.views`.`twitter_users` `twitter_users` ON
> (`twitter_tweets`.`user_id` = `twitter_users`.`user_id`)
> GROUP BY CASE
> WHEN `twitter_tweets`.`favorite_count` / 1 < 0
> AND `twitter_tweets`.`favorite_count` / 1 !=
> `twitter_tweets`.`favorite_count` / 1 THEN `twitter_tweets`.`favorite_count`
