Thank you michaelthuma.
I tried Actual ODBC driver, yes it is working good, but Actual ODBC company wants 29.95 USD for EACH Computer.
I will write a small program for taking some records from SQL server and about 500 users will use this program in our company.
And I must pay USD 14.975 as totaly. This is unacceptable for me.
I think OPEN database connectivity is NOT OPEN

FreeTDS is very comlex for me because I'm new in Mac.
I must find a solution but how ? I'm searching internet since 2 weeks for a solution.
