-## Testing inforamtion
-
-The SQL Server Dialect was tested with the jTDS 1.3.1 JDBC driver and SQL Server 2014.
-
-## Troubleshooting 
 
-- SQL SERVER jTDS JDBC driver contains a [bug](https://sourceforge.net/p/jtds/bugs/679/) in DATE type. 
-The returned datatype for a SQLServer DATE type is a VARCHAR with a length of 10. If you want to avoid it you can use a newer driver, for example:[mssql-jdbc-7.2.2.jre8.jar](https://www.microsoft.com/en-us/download/details.aspx?id=57782).
-Please, be aware that the new driver is not completely tested with Virtual Schemas. The driver's information for this dialect will be updated after we test the driver. 
+Please, do not forget to specify the `SCHEMA_NAME` property.
+
+Provide the SQL server's database name using one of the suggested ways:
+1. Via the `CATALOG_NAME` property;
+1. Via connection string definition: 'jdbc:sqlserver://<server name>:<port>/<database name>';
