This is a Type 4 driver and supports Sybase 10, 11, 12 and How do you handle SQL exceptions? Further, these drivers can be downloaded dynamically. This driver provides the highest performance driver for the database. The error description varies from driver to driver depending how vendor has implemented it. It consists of a set of interfaces and classes written in the Java programming language.

Mostly obsolete now 5. This driver uses Java to connect directly to Oracle. Advantages No need of database vendor library on the client.

The implementation class name for this type of driver is com. The results are then sent back through the reverse process Limited Java feature set May not be suitable for a large-scale application Type II: Driver types 1 and 2 are typically intended for programmers that write applications.
Jdbd-odbc the Bridge driver is not written fully in Java, Type 1 drivers are not portable. We are tring to provide a common plateform to the students and professionals to share their knowledge among others because knowledge is the only thing that increase when it is shared. It uses the client-side libraries of the database.
Lot of inconsistency in code as we are dealing with different vendor API. Java platform Data access technologies.
Better performance beidge Types 1 and 2. It provides better performance over the type 1 and 2 drivers as it does not have the overhead of conversion of calls into ODBC or database API calls.
May be useful for jdbc-oddbc that already have ODBC drivers installed on each client machine— typically the case for Windows-based machines running productivity applications. This differs from the type 4 driver in that the protocol conversion logic resides not at the client, but in the middle-tier.
The only point we wanted to highlight is limitztions way the SQL State code structure is. User needs to make sure the JDBC driver of the database vendor is loaded onto each client machine.
JDBC Driver Types
Using the above three information you can really show some in depth information to the end user. It depends on the number of databases the middleware has been configured to support.
This is the most used type of driver in JAVA world and the also has best performance as it talks with the database directly. Statement object will be used to fire the sql. It uses the limitxtions class libraries, so needs extra installation on client machine. Unlike the type 3 drivers, it does not need associated software to work.
Understanding JDBC Drivers
At client side, a separate driver is needed for each database. Oracle does supply an ODBC driver, but does not supply a bridge driver. Retrieved 27 June Please help improve it to make it understandable to non-expertswithout removing the technical details. In addition, performance is likely to be sub-optimal compared to a dedicated, native “Type 4” driver.
Best use is for controlled environments, such as an intranet. In such cases, the order in which the drivers are ov is significant because the DriverManager will use the first driver it finds jbdc-odbc can successfully connect to the given URL.
However the type 2 driver provides more functionality and performance than the type 1 driver as it does not have the overhead of the additional ODBC function calls. We will discuss other types as well–in the context of each of the supported databases—for a better understanding.
Needs some database-specific code on the middleware server. The latest version of this driver 9. There are four major components in JDBC. It is a Type 4 driver.
