If you don't have a client-server architecture and need to connect to DB from a computer that's not in LAN (e.g. Usually application server is on the same machine or same LAN as the SQL server.

SQL Server uses Windows (or Active Directory) to validate the current user. OK, your private address is something likeĪnd by public address you mean the address of the router ? Trusted authentication uses the security credentials of the current user to make the connection to SQL Server. This is going to sound really stupid, I was messing around with my firewall to disable it to test, and I ran into the private IP address of the computer, I put that in as the Server Name and the Connection Works fine.ĭo I have to do something special to connect to the external IP of a computer that has a private IP?

I downloaded it and put it in there but it didnt help.ĭoes anyone have any idea if it is because something might be wrong with my connection string or something else? If provider is not specified in a connection string, 32 bit OLE DB (including wow64 version on 64 bit OS) will use MSDASQL as the default provider while 64 bit OLE DB will use SQLOLEDB as the default provider. The only thing I noticed was that I did not have the DBMSSOCN.DLL file in my windows/system32 folder.

The following code illustrates access to the database table using analogues to Delphi ADO objects:ĪCon.ConnectionString = "Provider=MSDASQL.1 Persist Security Info=False Data Source=NameOfMyDSN" You can create ADO objects (connections, recordsets, commands, etc.) via OLE and then call their methods in scripts For more information, see Working With Databases. The script example below demonstrates both approaches: the TestSQL_ADO routine accesses the database table via analogues of Delphi ADO objects the TestSQL_ADO2 routine demonstrates access via native ADO objects. Some methods return objects that are analogues to Delphi ADO objects, The TestComplete ADO object includes methods of two kinds:

To create a DSN link, go to Control Panel | Administrative Tools | Data Sources (ODBC) and use the ODBC Data Source Administrator. To make the sample work, we created a DSN link to the Northwind database. The following code retrieves data from the Products table of the Northwind sample database that comes with Microsoft SQL Server and then writes this data to the test log.
