The Microsoft OLEDB Provider for SQL Server is the recommended provider for retrieving data from SQL server into Statistica. The recommendation is for this driver is for 2 reasons
1. SQL Server Native Client has been deprecated by Microsoft . See :
https://docs.microsoft.com/en-us/sql/connect/oledb/oledb-driver-for-sql-server?view=sql-server-ver15 2. The Native client does not allow for storing passwords. As a result the user will be prompted for password every time the data is retrieved from SQL Server.
NOTE : If using both the above mentioned providers is not viable option for some reason, another way to pull data from SQL Server into Statistica is to define a System DSN/ User DSN in Control Panel >> System And Security>> Administrative tools >> ODBC Data Sources using the SQL Server/SQL Server Native Client 11.0 ODBC driver.
From Statistica, data can then be retrieved using "Microsoft OLEDB provider for ODBC" driver and picking the User/System DSN defined in ODBC Data Sources while defining the database connection.
