Edward Capriolo commented on HIVE-4070:
---------------------------------------
Global conf variables that affect something like this are a bit scary. (It is
also not common in how hive works now, global vars only effect performance
usually not results. In the end 'like' is a UDF, I think the best solution is
to create mlike 'mysql like' and implement that to work as desired.
> Like operator in Hive is case sensitive while in MySQL (and most likely other
> DBs) it's case insensitive

> Hive's like operator seems to be case sensitive.
> See
> https://github.com/apache/hive/blob/trunk/ql/src/java/org/apache/hadoop/hive/ql/udf/UDFLike.java#L164
> However, MySQL's like operator is case insensitive. I don't have other DB's
> (like PostgreSQL) installed and handy but I am guessing their LIKE is case
> insensitive as well.
