如何在HANA SQL数据库中列出用户定义的类型？

Question

我希望能够获得用户定义类型的列表，类似于通过调用列出用户定义的过程

select * from SYS.PROCEDURES order by PROCEDURE_NAME;

Answer 1

As table types are the only user-definable types in SAP HANA you find those in the TABLES system table:

SELECT 
       * 
FROM 
     tables 
WHERE 
      is_user_defined_type ='TRUE';
