Difference between jdbc type 2 and type 4 drivers

 · If you are accessing one type of database, such as Oracle, Sybase, or IBM, the preferred driver type is type If your Java application is accessing multiple types of databases at the same time, type 3 is the preferred driver. Type 2 drivers are useful in situations, where a type 3 or type 4 driver is not available yet for your www.doorway.ruted Reading Time: 4 mins.  · You should always use a type 4 JDBC driver, there is hardly any situation when you need to go to the previous version of the JDBC driver.

You should always use a type 4 JDBC driver, there is hardly any situation when you need to go to the previous version of the JDBC driver. Though, if you want to connect to Oracle database using TNS name using OCI client, you need to use type 2 JDBC driver also known as a thick JDBC driver. Type 4 drivers are the ones you probably want to stick with. The Java program connects directly to the database, meaning that if there is a problem, it will be captured entirely within the JVM of the program making the connection (type 1, it's in the ODBC layer, type 2 it's in the native compiled code, type 3 it's in the remote network proxy). Again none of this has to do with functionality; however, they all impact how to deploy, how to debug, and how to configure the database connection. Description. There are 4 types of JDBC drivers in Java. type 4 drivers are most advanced and fast and same time easy to use. Just include the jar file of driver.

JDBC drivers are divided into four types or levels. The different types of jdbc drivers are: Type 1: JDBC-ODBC Bridge driver (Bridge) Type 2. It also removes 3 tier architecture of type 3 JDBC driver which makes it faster than type 3. Major development happens on type 4 JDBC driver when databases. What are the major differences between the 4 types of JDBC driver? The proper function of Type-1 and Type-2 drivers rely completely or partially on.
