JDBC mean Java Database Connectivity. In java, using JDBC drivers, we can connect to database.
Steps to connect to JDBC.
1) Load the driver, using Class.forName(DriverName);
2) Get the connection object, Connection con = Driver.getConnection(loaded driver name);
3) Create a SQL statement, Statement s = con.createStatement();
4) Create Resultset object using the statement created above, ResultSet rs = s.executeQuery("sql statement");
Iterate the result set to get all the values from the database.
Finally don't miss this
6) con.close() ;
jdbc-odbc bridge is a jdbc driver required to connect java application to the specified database. Using this driver the java calls are converted to the odbc calls and then are referred to the database. Since odbc driver are the implemetation of the API written in C language. As in the case of this driver the API is provided by Sun MicroSystem itself and the implementation of these API is done by the Database Vendors.
JDBC is the acronym for "Java Database Connectivity". JDBC actually offers a two-way interface towards a specific database (like for example Oracle or DB2) and to the actual Java application. The technical part towards the database is encapsulated in a vendor-dependent "database driver", but the part towards the Java application is totally vendor independent. Hence if the database gets replaced by a different vendor mostly no coding changes are necessary.
JDBC stands for Java Database Connectivity . It was developed by Java soft and is a part of Java Enterprise API. JDBC is the first standardized API that allows the users to develop database front ends without continously rewriting their code. JDBC provides the ability to create robust, platform-independent application and wev-based applets, wihich can acces any database through a DBS-independent mechanism. The interaction between these application and applets with SQL data sources is done through a set of relational database objects and methods defined is the JDBC API.
Ans:Loading a class in JDBC For getting connection to database and to query database for INSERT,UPDATE,DELETE and to do some operations on database through java programs you need to load the jdbc driver class for a particular database provided by the database provider for that you use class.forName() Method this method will load the class which are necessary for database operations
If you want to connect to any database, you need to follow certain methods. Start by creating a database connection, configuring, binding data and testing.Different programming languages have different ways to connect. For example, in visual studio .Net, if you want to connect to any database then you need to follow the database configuaration wizard. That means you connect your application to a database by running the "data source configuration wizard" and selecting database on the "choose a data source type" page.Another example: suppose you are using Java..Regardless of whether you're trying to connect to Oracle, SQL Server, MySQL, Postgres, mSQL, Interbase (or any other JDBC data source), establishing a connection to a database with Java JDBC is a simple two-step process:1)Load the JDBC driver.2)Establish the JDBC connection to your databaseYou can also use Microsoft Access and once you have data objects such as tables, views, proceduers, etc. then you can connect by following the self explanatory wizards.This answer might give you a generic idea since the question is a generic question.If you need further assistance then send your query to:firstname.lastname@example.orgJitendra**Grammar corrected by gbaughma**Additional note from gbaughma: MS Access doesn't do stored procedures. ;)
No. SQL stands for Structured Query Language and that in itself is a language and it is totally different from Java. However, you can use SQL queries inside Java code with the help of JDBC (Java DataBase Connectivity). But the Java compiler cannot understand/compile standalone SQL syntax unless it is used as part of JDBC.
Actually coming to this one, we need to discuss about those companies which are invented the java(Sun Micro System) and database(Oracle), in olden days these companies were tie up that time, so that's why we are accessing the database with application program written in java. now coming to our topic, We need to select the suitable drivers to our application(Desktop or Web Application) load the drivers through application. Those drivers are JDBC drivers, JDBC is nothing but pool of drivers in which some drivers are default in Windows OS, when ever we create the DATABASE Application like ORACLE, then automatically drivers are also included in JDBC.
