Java sql Package

The java.sql package is a part of the Java Standard Edition platform (Java SE) that provides the API for accessing and manipulating relational databases. It includes a set of classes and interfaces that enable Java applications to interact with relational databases such as MySQL, Oracle, Microsoft SQL Server, and others.

The java.sql package includes classes for connecting to a database, executing SQL queries, retrieving and updating data, and managing database transactions. Some of the important classes and interfaces in the java.sql package are:

• DriverManager: A class for managing a list of database drivers and establishing connections to databases.
• Connection: An interface that represents a connection to a database and provides methods for executing SQL statements and managing transactions.
• Statement: An interface that represents an SQL statement and provides methods for executing queries and updates.
• ResultSet: An interface that represents a set of rows returned by a query and provides methods for retrieving data from the result set.

To use the java.sql package, you need to import the relevant classes and interfaces into your Java code and then use them to interact with the database. The java.sql package also provides support for handling exceptions that may occur during database operations.

In addition to the java.sql package, there is also a javax.sql package that provides extensions to the basic JDBC API. The javax.sql package includes classes and interfaces for connection pooling, distributed transactions, and other advanced database features.
