JDBC Connection to MSSQL-Database in Netweaver Portal

Question

We are running into problems when trying to create a Query- or JDBC iView to retrieve data from a MS SQL server table.
Here is what we have tried on 2 different EP portals.
Portal versions:
6.0.12.0.0 (NW04 SPS12)
6.0.14.0.0 (NW04 SPS14)
Step 1: Created a JDBC system.
Connection URL  - jdbc:microsoft:sqlserver://<servername>:1433;DatabaseName=name
Driver Class Name  - com.microsoft.jdbc.sqlserver.SQLServerDriver
Connection Factory Class  – JDBCFactory
Admin User ID (DQE)  –  database admin name
Admin Password (DQE)  – database admin password
User Mapping Type  – admin;user
Step 2: Created an alias for this JDBC system, for example, test_JDBC_system.
Step 3: Added user mapping.
Search for my user ID in the User Mapping in User Admin section, click on “Edit”, and select the JDBC alias name “test_JDBC_system” in the system dropdown list, and then put database admin user name and database admin password in the fields “User” and “Password”, and click on “Save”.
Step 4: Tested the connection.
“Connection Test Through DQE” was successful, but “Connection Test for Connectors failed”. Error message was:
Results
Retrieval of default alias successful
Connection failed. Make sure user mapping is set correctly and all connection properties are correct.
Step 5: Created a JDBC stored procedure iView.
Got an error message like this “Error connecting to backend application. Check your system and user mapping settings. Contact your system administrator if problem persists.”
Step 6: Because we couldn’t successfully create JDBC iView, so we tried to created a Query iView instead.
It showed me the system alias, and I could drill down all the way to the table level and put in my query, for example, SELECT cdb_admin.Land.Land FROM cdb_admin.Land (table name is “land” and the column name is also “land”, cdb_admin is the admin user). But it gave me an error when previewing it – “Query execution failed. Exception message: ”
Here are our issues/thoughts:
We don’t know how to do the user mapping, not sure what to put into “User” and “Password” fields.
The documents saying these versions have the SQL Server Driver installed already, but we couldn’t see the “com.microsoft.jdbc.sqlserver.SQLServerDriver” under System Drivers in “JDBC connector” in SAP Visual Admin.
In some document, it used “com.sap.jdbc.sqlserver.SQLServerDriver”, and we don’t see that in the system driver list either.
We tried to deploy MS SQL driver 3 jar files msbase.jar, mssqlserver.jar, msutil.jar by adding a new driver under “JDBC connector” in SAP VA. We gave it a name “MSSQL”. But we don’t know if we referred to the SQLServerDriver class correctly by entering “Driver Class Name  - com.microsoft.jdbc.sqlserver.SQLServerDriver” when creating the JDBC system in the portal.
It seems like we connected to the database server and tables when using Query iView, but why did we get this “Query execution failed. Exception message: ”? We tried to modify the query to “select land from land” too, but it didn’t work either, same error message. So is it really the SQL statement wrong? There is not much documentation on Query iView and can you give me some hints?
Thanks very much..

Hi,
in "User" and "Password" field you need to give database administrator User-ID and Password.
You just need to give proper Database url and Driver class name to access MS SQL thro JDBC system.
Have you set the security settings for the database, check the <b>prerequsites</b> in the following link:

Hope it helps
