Creating an ODBC data source using Python

For the cross-platform installer I am creating, I need to create ODBC data sources for Windows installations. Thanks to the Python ctypes module the solution was as simple as:


import ctypes

ODBC_ADD_DSN = 1 # Add data source
ODBC_CONFIG_DSN = 2 # Configure (edit) data source
ODBC_REMOVE_DSN = 3 # Remove data source
ODBC_ADD_SYS_DSN = 4 # add a system DSN
ODBC_CONFIG_SYS_DSN = 5 # Configure a system DSN
ODBC_REMOVE_SYS_DSN = 6 # remove a system DSN

def create_sys_dsn(driver, **kw):
"""Create a system DSN
Parameters:
driver - ODBC driver name
kw - Driver attributes
Returns:
0 - DSN not created
1 - DSN created
"""
nul = chr(0)
attributes = []
for attr in kw.keys():
attributes.append("%s=%s" % (attr, kw[attr]))

return ctypes.windll.ODBCCP32.SQLConfigDataSource(0, ODBC_ADD_SYS_DSN, driver, nul.join(attributes))

if __name__ == "__main__":
print create_sys_dsn("SQL Server",SERVER="(local)", DESCRIPTION="SQL Server DSN", DSN="SQL SERVER DSN", Database="mydatabase", Trusted_Connection="Yes")
print create_sys_dsn("mySQL",SERVER="local", DESCRIPTION="mySQL Server Test1", DSN="mySQL DSN", DATABASE="mySQLDb", UID="username", PASSWORD="password", PORT="3306", OPTION="3")

By "as simple as", I assume you mean "as relatively simple as". :)
