Default timestamp value missing - func.now() not supported

**Is your feature request related to a problem? Please describe.** I use the sqlalchemy lib to support anyDB in my solution. So far sqlite and postgres support all used features. Today I tested my code against a SAP HANA Cloud instance (created yesterday) and got the error "(hdbcli.dbapi.ProgrammingError) (257, 'sql syntax error: incorrect syntax near "now": line 13 col 30 (at pos 316)')". The create table statement for the column was: CREATE TABLE some_table ( uuid CHAR(32) NOT NULL, ... created_at DATETIME DEFAULT now(), ... PRIMARY KEY (uuid) ) The syntax "now()" as default value is not supported? **Describe the solution you'd like** From the python perspective the column is defined as: from sqlalchemy import Column, ... from sqlalchemy.sql import func Column(DateTime(timezone=True), server_default=func.now()) I think func.now() can be implemented for the SAP HANA dialect and set the accepted statement? **Describe alternatives you've considered** At the moment I will remove the default values from the model and set the now() value by my code. This is not the best solution... **Additional context** Not at the moment. Code examples should be enough? If not, call me. Thanks for supporting us! Best regards Joerg
