Driver Location RazorSQL uses JDBC drivers to connect to the database. RazorSQL needs to know the location of the JDBC drivers on the file system in order to use them to connect to the database. The "Driver Location" field is used to tell RazorSQL where the drivers are stored on the file system. Usually, database vendors or third party companies provide JDBC drivers in ".jar" files. To set the "Driver Location". browse the file system using the "Browse" button and select the jar file that contains the JDBC drivers. If the vendor provides the drivers as a zip file download, be sure to extract the files from the zip file to find the jar file. If the JDBC driver is located in more than one jar file, separate the files with semicolons. For example, if using the Microsoft SQL Server driver provided by Microsoft, you may need to enter the following in the class location field: C:\drivers\mssqlserver.jar;C:\drivers\msbase.jar;C:\drivers\msutil.jar
