Mihai Budiu commented on CALCITE-1466:
--------------------------------------
I see that JOOQ has a set of Java classes for Unsigned values, which are
Apache-licensed:
https://github.com/jOOQ/jOOQ/tree/main/jOOQ/src/main/java/org/jooq/types, so
for runtime support we could probably use these. Probably taking JOOQ as a
dependency would be excessive, it would be nice if we could get just this piece.
> Support for UNSIGNED types of TINYINT, SMALLINT, MEDIUMINT, INT, BIGINT in

> There are some data bases like MySQL supporting unsigned data types. Apache
> Phoenix also supports them. Would be great to add them to calcite as well.
