HANA Data types & PK

Hi,

I can't create primary keys on any text data type like shorttext or even char in a column store. Any insight appreciated.

Second, according to the help (Data Types - SAP HANA SQL and System Views Reference - SAP Library) there should be a Boolean data type. However, I can't create columns with this type either (SAP DBTech JDBC: [257]: sql syntax error: this feature cannot be supported).

Thanks,

Andreas
