To use ODBC with OpenESQL, you must have the following in place:
Install at least one ODBC driver of your choice.
Note: When using the SQL Server driver installed automatically by most Windows operating systems, be sure that the driver corresponds
to the release of SQL Server you are using.
(applies to Windows environments only)
Install and configure ODBC Driver Manager and the ODBC driver software. See your Driver Manager or Driver vendor documentation
for details.
Create at least one data source name (DSN) that identifies a database to which you can connect. On Windows platforms only, you can do this using the ODBC Data Source Administrator. For more information, see
To start the ODBC Data Source Administrator.
