Quick Answer: What is the advantage of JDBC in Java?

It automatically creates the XML format of data from the database. It does not require the content to be converted. It provides full support to query and stored procedure. It provides support to both Synchronous and Asynchronous processing.

What are the advantages of JDBC over ODBC?

JDBC is simpler and easier to learn than ODBC. JDBC is not primarily targeted for desktop application development, which makes for faster implementation outside the Windows environment and is frequently used in enterprise class applications.

What is advantage of Java connectivity?

Advantages for using this type of driver include the following: Allows access to almost any database since the databases ODBC drivers are readily available. Offers significantly better performance than the JDBC/ODBC Bridge. Limited Java feature set.

Why do we need JDBC statements in Java?

The JDBC Statement, CallableStatement, and PreparedStatement interfaces define the methods and properties that enable you to send SQL or PL/SQL commands and receive data from your database. They also define methods that help bridge data type differences between Java and SQL data types used in a database.

What are the advantages and disadvantages of JDBC ODBC bridge driver?

Advantage : Almost any database for which ODBC driver is installed, can be accessed. Disadvantage : a) Performance overhead since the calls have to go through the JDBC overhead bridge to the ODBC driver.

Is JDBC better than ODBC?

As you can see, with less number of records being fetched from the database, C(ODBC) performed better. But as the number of records were increased, Java(JDBC) came out as the winner.

Is an advantage of JDBC Mcq?

Which of the following is advantage of using JDBC connection pool? Explanation: Since the JDBC connection takes time to establish. Creating connection at the application start-up and reusing at the time of requirement, helps performance of the application.

What is JDBC and JDBC drivers?

A JDBC driver uses the JDBC™ (Java Database Connectivity) API developed by Sun Microsystems, now part of Oracle, that provides a standard way to access data using the Java™ programming language. … Using JDBC allows you to write one application that can send SQL statements to different data sources.

What is JDBC drivers in Java?

A JDBC driver is a software component enabling a Java application to interact with a database. JDBC drivers are analogous to ODBC drivers, ADO.NET data providers, and OLE DB providers. To connect with individual databases, JDBC (the Java Database Connectivity API) requires drivers for each database.

What is JDBC architecture in Java?

Java Database Connectivity (JDBC) architecture is an API specifying interfaces for accessing relational databases. JDBC helps to connect to a database, send queries and updates to the database, and retrieve and process the results obtained from the database for queries.

What are the functions of the JDBC connection interface?

Constructs an object that implements the NClob interface. Constructs an object that implements the SQLXML interface. Creates a Statement object for sending SQL statements to the database. Creates a Statement object that will generate ResultSet objects with the given type and concurrency.

What is the purpose of Statement object in JDBC?

A Statement object is used to execute a simple SQL statement with no parameters. A PreparedStatement object is used to execute a pre-compiled SQL statement with or without IN parameters. A CallableStatement object is used to execute a call to a database stored procedure.

What is requirement of JDBC?

How many JDBC driver types does Java define?

Today, there are five types of JDBC drivers in use: Type 1: JDBC-ODBC bridge. Type 2: partial Java driver. Type 3: pure Java driver for database middleware.

What is Savepoint in Java?

A Savepoint object is used to mark intermediate point within the current transaction. After setting a savepoint, the transaction can be rolled back to that savepoint without affecting preceding work. The Connection. setSavepoint() method is used to set a savepoint object within the current transaction.

What is JDBC-ODBC?

ODBC is an SQL-based Application Programming Interface (API) created by Microsoft that is used by Windows software applications to access databases via SQL. JDBC is an SQL-based API created by Sun Microsystems to enable Java applications to use SQL for database access.
