DOWNLOAD JDBC ODBC DRIVER FOR JAVA CODE

Requires that some binary code be loaded on each client machine.

Native-API Partly Java Driver: This style of driver converts JDBC calls into calls on the client API for Oracle, Sybase, Informix and the like.

Both ODBC binary code and sometimes the database client code must be loaded on each machine that uses this driver.

JDBC-ODBC Bridge plus ODBC Driver: The Sun bridge product provides JDBC access via ODBC drivers.

You may also use ODBC drivers and existing database client libraries as part of a JDBC connectivity solution: The middleware provides connectivity to many different datab Pure Java Driver for Database Middleware: This type of driver translates JDBC calls into the middleware vendorвЂ™s protocol, which is then translated to a DBMS protocol by a middleware server.Direct-to Database Pure Java Driver: This type of driver converts JDBC calls into the network protocol used directly by DBMSs, allowing a direct call from the client machine to the DBMS server and providing a practical solution for intranet access.Use the new SQе…ѓ datatypes as column valuesДЄpplications and Applets may access databases via JDBC using pure Java drivers as follows:.Send multiple SQL statements to the database as a unit, or batch.Make updates to database tables using methods in the Java programming language instead of using SQL commands.Scroll forward and backward in a result set or move to a specific row.JDBC2.0 offers the following improvements over JDBC1.0: A programmer can invoke the getMetaData method to obtain a ResultSetMetaData object which can obtain the types and properties of a result set. Numerous methods exist for manipulating data in the ResultSet object The object maintains a cursor that points to the current row of data. Both object types allow for passing parameters in an SQL statement.ДЄ ResultSet object holds the rows returned by a database when you execute a query Statement. A CallableStatement object is used to represent and execute a sto A PreparedStatement object is used to precompile and then execute a statement multiple times. Statement objects are important extensions to the Statement interface. Programmers can allocate multiple Statement objects and reuse each one repeatedly to process many SQL statements. Statement objects are used as containers to execute SQL statements on a connection. Very few clients need to use the DriverPropertyInfo class in order to discover and supply properties for connections. (more on URLs later) The DriveManager class is part of JDBC runtime and it loads Driver objects and creates database Connection objects as y IverManager uses to locate a driver for the database Uniform Resource Locator (URL) you specify. Every JDBC driver must implement the Driver interface. 90% of what you will need to do with a database will be found in these interfaces and classes.

The JDBC Core consists of seven (7) interfaces and two (2) classes. One exciting fact is that drivers necessary to connect to respective database can be loaded dynamically along with an applet. From the programmerвЂ™s point of view, JDBC is simply another package callД®d java.sql.*.

Remember, the JDBC API is for both using and creating low-level JDBC drivers. This is about as simple as it gets: JDK1.1 implements JDBC1.0, and JDK1.2 will implement JDBC2.0. One should note here that MicrosoftвЂ™s ODBC is also based on the X/Open SQL CLI. If itвЂ™sД®asier, you can think of the CLI as a SQL wrapper. Now comes the confusing point while JDBC draws heavily from SQL-92 it is based on the X/Open SQL Call Level Interface (CLI). This does not imply that a JDBC driver must implement every SQL-92 function, it may implement a subset of the whole. JDBC draws heavily from the ANSI SQL-92 standДЄrd. The JDBC Project was started in January, 1996 and the specification was frozen in June, 1996 to seek the input of industry database vendors to insure that JDBC would be widely accepted upon its release. Ing native methods to bridge to existing database access libraries. JDBC drivers can either be entirely written in Java so that they can be downloaded as part of an applet, or they can be implemented us The JDBC API is implemented via a driver manager that can support multiple drivers connecting to different databases. It allows a Java programmer to do three things:

Ines Java classes that represent databaseД¬onnections, SQL statements, result sets, database metadata, etc. All the benefits of 'Write Once, Run Anywhere' equally apply to JDBC. Java Database Connectivity(JDBC) is the industry standard for database-independent connectivity between Java applets/applications and a broad range of SQL databases.
