Type 4: JDBC Net pure Java Driver - A native-protocol fully Java technology-enabled driver converts JDBC technology calls into the network protocol used by DBMSs directly.

JAVA 8 JDBC ODBC BRIDGE ALTERNATIVE DRIVERS

Several vendors are adding JDBC technology-based drivers to their existing database middleware products. In order for these products to also support Internet access they must handle the additional requirements for security, access through firewalls, etc., that the Web imposes. It is likely that all vendors of this solution will provide products suitable for Intranet use. In general, this is the most flexible JDBC API alternative. The specific protocol used depends on the vendor. This net server middleware is able to connect all of its Java technology-based clients to many different databases. Type 3: Network protocol Driver- A net-protocol fully Java technology-enabled driver translates JDBC API calls into a DBMS-independent net protocol which is then translated to a DBMS protocol by a server.

Note that, like the bridge driver, this style of driver requires that some binary code be loaded on each client machine. Type 2: Native API Partly Java Driver- A native-API partly Java technology-enabled driver converts JDBC calls into calls on the client API for Oracle, Sybase, Informix, DB2, or other DBMS. For information on the JDBC-ODBC bridge driver provided by Sun. Hence, this kind of driver is generally most appropriate when automatic installation and downloading of a Java technology application is not important. Note that some ODBC native code and in many cases native database client code must be loaded on each client machine that uses this type of driver. Type 1 : JDBC-ODBC Bridge Driver - A JDBC-ODBC bridge provides JDBC API access via one or more ODBC drivers. There are mainly four type of JDBC drivers available. Connection pool manager maintains a pool of open database connections.ġ0. What are the different JDB drivers available? Connection pooling increases the performance of Web applications by reusing active database connections instead of creating a new connection with every request. This information is obtained with the getMetaData method.Ĭonnection pooling is a technique used for sharing server resources among requesting clients. SQL statements are executed and results are returned within the context of a connection.Ĭonnection object's database is able to provide information describing its tables, its supported SQL grammar, its stored procedures, the capabilities of this connection, and so on. The next method moves the cursor to the next row, and because it returns false when there are no more rows in the ResultSet object, it can be used in a while loop to iterate through the result set.Ĭonnection class represents a connection (session) with a specific database. Initially the cursor is positioned before the first row. ResultSet object maintains a cursor pointing to its current row of data. It is the basic service for managing a set of JDBC drivers.Ī table of data representing a database result set, which is usually generated by executing a statement that queries the database. By using this connection, we can create a statement object and this object will help us to execute the query.ĭriverManager is a class in java.sql package. What are the steps required to execute a query in JDBC?įirst we need to create an instance of a JDBC driver or load JDBC drivers, then we need to register this driver with DriverManager class. This driver is used to connect to the database.Ĥ. The JDBC Driver provides vendor-specific implementations of the abstract classes provided by the JDBC API.

Each Database has it's own stored procedure language, With a JDBC technology-enabled driver, you can connect all corporate data even in a heterogeneous environmentĪ stored procedure is a set of statements/commands which reside in the database.

JDBC technology is an API (included in both J2SE and J2EE releases) that provides cross-DBMS connectivity to a wide range of SQL databases and access to other tabular data sources, such as spreadsheets or flat files.
