trouble with mxODBC, unixODBC and MSSQL

[erik.myllymaki at gmail.com]

I am using a script that's worked for me in the past on Windows, but
now that i've moved it to a Linux machine it is not. The trouble seems
to be when trying to insert escaped characters into a  varchar field
(\n \r ,etc.).

-----------------------------------------------------------------------------
# conn = mx.ODBC.WINDOWS.DriverConnect('DSN=myDSN;UID=sa;PWD=pwd')

conn = mx.ODBC.unixODBC.DriverConnect('DSN=myDSN;UID=sa;PWD=pwd')
curr = conn.cursor()

# These strings do not work:
# mystring = "Some text \n and some other text"
# mystring = "Some text \t and some other text"
# mystring = """Some text
and some other text"""

# This tring works just fine:
mystring = "Some text and some other text"


sql_insert = "insert into DEV..msg(message_id,body) values(?,?)"

curr.execute(sql_insert, (1,mystring))
curr.close()
conn.commit()
-----------------------------------------------------------------------------

Here's the error message:

Error Type: OperationalError
Error Value: ('', 8179, '[unixODBC][FreeTDS][SQL Server]Could not find
prepared statement with handle 0.', 6083)

Any ideas greatly appreciated.
