Zhengqiang Duan commented on CALCITE-1466:
------------------------------------------
Hi [~mbudiu], I looked at the https://github.com/jOOQ/jOOU library, it provides
UByte, UShort, UInteger, and ULong, which are consistent with the UNSIGNED type
range in MySQL. I think we can integrate it into calcite avatica.
In addition, MySQL also provides the MEDIUMINT [UNSIGNED] type -
https://dev.mysql.com/doc/refman/5.7/en/integer-types.html, which has no
complete corresponding type in JDK and Joou. Do you think MediumInteger and
UMediumInteger should be added to handle this type?
> 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.
