that's what literal_binds is for but it doesn't support formatting
every kind of type directly, so I assume you're getting an error
message, at the moment the literal_processor can't be injected so you
have to use a new type:
from sqlalchemy import *
from sqlalchemy.dialects import postgresql
from sqlalchemy.ext.compiler import compiles
import datetime
class SDateTime(TypeDecorator):
impl = DateTime
def literal_processor(self, dialect):
return lambda value: str(value)
print(
select([column("q", SDateTime) == datetime.datetime.now()]).compile(
dialect=postgresql.dialect(), compile_kwargs=dict(literal_binds=True)
)
)
