Package: python-sqlalchemy
Version: 0.5.3-1
Severity: normal
When trying to autoload a table on a remote mssql server, sqlalchemy
crashes.
This may be related to http://www.sqlalchemy.org/trac/ticket/1312.
I have tried this on a lenny box with the sqlalchemy 0.5.2 backport, and it
does not have the problem.
My script to demonstrate the problem:
#!/usr/bin/python
#
# Demonstrates the exeption thrown by sqlalchemy 5.3, but not 5.2, on my
# debian systems
#
import sqlalchemy
import trinconfig
def main():
a = get_create_eng_args()
engine = sqlalchemy.create_engine('mssql://%s:%...@%s/%s' % a )
meta = sqlalchemy.MetaData()
meta.bind = engine
community_table = sqlalchemy.Table('Community', meta, autoload=True)
def get_create_eng_args():
return ('user', '12345', 'db01', 'project-DB')
if __name__ == '__main__':
main()
The output when run on this box:
$ ./demo_problem.py
Traceback (most recent call last):
