I have some generic timestamp columns as part of a mixin. I'd like
for these columns to have server defaults of the current UTC time.
If I wanted local time, I could just do:
created_ts = Column(DateTime, ...,
server_default=sasql.text('CURRENT_TIMESTAMP'))
The problem I'm running into is that the DB servers all have a
different way of getting UTC time:
SQLITE: select CURRENT_TIMESTAMP
Microsoft SQL: select GETUTCDATE()
PostgreSQL: select (now() at time zone 'utc')
So how do I set the server default in a db specific way when I want
to be able to define the columns in a library that will be used on
different DB servers?
yup this is a common one, so much that here it is right here:
