Review Comment:
Some comments here would be welcome. In particular I'm having trouble seeing why 934 should pass and 940 should fail. (I also find it surprising that 934 and 936 should pass given the use of whitespace in the WHERE clause.)

> Implement Binary and Hexadecimal literals
> -----------------------------------------
>
> Key: PHOENIX-6764
> URL: https://issues.apache.org/jira/browse/PHOENIX-6764
> Project: Phoenix
> Issue Type: Bug
> Components: core
> Reporter: Istvan Toth
> Assignee: Istvan Toth
> Priority: Major
>
> Currently there is no sane way to specify arbitrary binary and varbinary values in the query string.
> They can be set as variables for preparedstatements, and if the length corresponds to an existing type, then some casting gymnastics can be used to work around the problem, but I have not found a way to write a query that upserts an arbitrary three byte value into a binary/varbinary.
> The SQL standard defines Binary and Hex literals in the form ofÂ
> B'01010101001...' and X'0102AAF5...'
> Implement this in the parser.
