Connecting SQL Server Management Studio to SAP ASE via ODBC Driver
In order to avoid incorrect integration with MS SSMS, the working environment must meet the following conditions:
You can use the Microsoft SQL Server Management Studio to connect your ASE data to an SQL Server instance. Linked Server is a tool of MS SQL Server that allows to execute distributed queries to refer tables stored on non-SQL Server datbase in a single query. With linked servers, you can execute commands against different data sources such as ASE and merge them with your SQL Server database. You can create a linked server with one of these methods: by using the options in the Object Explorer or by executing stored procedures.
Below are major advantages of using SQL Server Linked Servers to connect to ASE:
You can follow the steps to create a linked server for ASE in SQL Server Management Studio by using Object Explorer:
The linked server will appear under the Linked Servers in the Object Explorer Pane. You can now issue distributed queries and access ASE databases through SQL Server.
Ensure the Allow inprocess option of MSDASQL OLE DB Provider for ODBC Drivers is enabled. For this, find the MSDASQL provider in the list of Linked Servers and double-click on it
In the appeared Provider Options window, enable the Allow inprocess checkbox:
Create a new Linked Server
Make sure to select Microsoft OLE DB Provider for ODBC Drivers:
Now you need to input the Linked Server name, e.g. ASE. In the Product Name and Data Source fields you need to indicate the System DSN that you've previously created - more info on System DSN setup can be found here.
The ASE tables are already available to be fetched. To query the linked server, click New Query in the toolbar:
Enter your SQL query in the editor window and click Execute to run the query:
As a result, you can see the contents of the selected table retrieved directly from the ASE account you are connected to.
