sqlalchemy date type in 0.6 migration using mssql
- by nosklo
I'm connection to mssql server through pyodbc, via FreeTDS odbc driver, on linux ubuntu 10.04.
Sqlalchemy 0.5 uses DATETIME for sqlalchemy.Date() fields.
Now Sqlalchemy 0.6 uses DATE, but sql server 2000 doesn't have a DATE type. How can I make DATETIME be the default for sqlalchemy.Date() on sqlalchemy 0.6 mssql+pyodbc dialect?
I'd like to keep it as clean as possible.
Here's code to reproduce the issue:
import sqlalchemy
from sqlalchemy import Table, Column, MetaData, Date, Integer, create_engine
engine = create_engine(
'mssql+pyodbc://sa:sa@myserver/mydb?driver=FreeTDS')
m = MetaData(bind=engine)
tb = sqlalchemy.Table('test_date', m,
Column('id', Integer, primary_key=True),
Column('dt', Date())
)
tb.create()
And here is the traceback I'm getting:
Traceback (most recent call last):
