sqlalchemy connect to server, with not specify database

问题

Is it possible to connect to MSSQL server, using sqlalchemy and thencreate a database?

I use the following:

sqlalchemy.create_engine("mssql+pyodbc://sa:pwd@localhost/")

But I get an error:

Detail DBAPIError: (Error) ('IM002', '[IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified (0) (SQLDriverConnect)') None None

I would like to connect to the server, then create database and work with it.

回答1:

Give it a try:

import urllib

connection_string = "DRIVER={SQL Server};SERVER=localhost;UID=sa;PWD=pwd"
connection_string = urllib.quote_plus(connection_string) 
connection_string = "mssql+pyodbc:///?odbc_connect=%s" % connection_string

engine = sqlalchemy.create_engine(connection_string)
connection = engine.connect()
connection.execute("create database test")
connection.close()

Part of the code was taken from this answer.

Hope that helps.
