Java Programming with Oracle JDBC. Preface. Why I Wrote This Book. This Book's Intended Audience. Structure of This Book. Conventions Used in This Book. Feb 3, In this post, we feature a comprehensive JDBC Tutorial (Java Database Connectivity), an API provided by Oracle that allows programmers to Databases - Batch commands - Transactions - CRUD commands. JDBC. 4 types of JDBC drivers. Type 1: JDBC-ODBC bridge. It is used for local connection. ex) 32bit It is independent from h/w because this driver is in Java.
RowSet is serialized. So, we can pass Rowset from one class to another class because it has no connection with the database.
If you want to turn Off the Auto Commit then set connection. No, we cannot get null Resultset. Metadata means data or information about other data.

We use metadata to get database product version, driver name, the total number of tables and views. Advantages of using a connection pool? Connection pooling means connections will be stored in the cache and we can reuse them in future. It is an interface between user and drivers. DriverManager tracks all the activity between a database and the appropriate driver. Batch updates can be used only for insert, update and delete but not for select query.
Connection interface handles transaction management in JDBC. This driver is native code and not Java, and is closed source. The native code part is targeted at a specific database product i.

This architecture eliminated the need for the ODBC driver and instead directly called the native client libraries shipped by the database vendors. The intermediate server then connects to the database on behalf of the JDBC driver.
The middle-tier application server converts JDBC calls directly or indirectly into the vendor-specific database protocol.
Type 3 drivers had a Java client component and a Java server component, where the latter actually talked to the database.
It is implemented for a specific database product. Today, most JDBC drivers are type 4 drivers.
Written completely in Java, type 4 drivers are thus platform independent. They install inside the Java Virtual Machine of the client.

This provides better performance than the type 1 and type 2 drivers as it does not have the overhead of conversion of calls into ODBC or database API calls. Unlike the type 3 drivers, it does not need associated software to work. This architecture encapsulates the entirety of the JDBC API implementation along with all the logic for communicating directly with the database in a single driver.
I love computers, programming and solving problems everyday. A family guy with fun loving nature. You can find me on Facebook , Twitter and Google Plus.This pre-installation issue is also true for JDBC drivers that use native methods.
No additional library installation on client side. The package that contains all the required classes and interfaces for JDBC programming is java.
Now that we have employees and departments neatly contained, we can add another table, called PROJECT, to keep track of the projects each employee is involved in. Other drivers, which may not be shipped with NetBeans, may need to be imported as a separate jar file.
The basic units in SQL are tables, columns, and rows. DriverManager; import java.
Getting down to the real functional differences, we see this list as the requirements for Type 5 Drivers as follows: Codeless Configuration The ability to modify options, check statistics and interact with the driver while it is running.
A column represents a data element present in a table, while a row represents an instance of a record, or entry, in a table.
This flexibility will be a major selling point for developers who are bound to legacy database systems but who still want to extend their client applications.
