To use ODBC with OpenESQL, you must have the following in place: 
               	 
               
 
                  		
                  - Install at least one ODBC driver of your choice. 
                     		   
                     		  
                      
                        			 
                        - 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. 
                           			 
                        
- When using HCOSS, you must use an ODBC driver for SQL Server 2008 or later. 
                           			 
                        
 
- 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. You can do this using the ODBC Data Source Administrator. For more information, see 
                     			 To start the ODBC Data Source Administrator.
