Advantages of Using a PreparedStatement Over a Statement in JDBC

When working with JDBC in Java, using a PreparedStatement offers several advantages over a Statement for executing SQL queries:

1. Precompiled Statements: PreparedStatement objects are precompiled on the database server, which can lead to improved performance especially when executing the same SQL statement multiple times with different parameters.
2. Parameterized Queries: PreparedStatement allows for parameterized queries, which help prevent SQL injection attacks and improve code readability by separating SQL logic from user input.
3. Improved Readability: Using PreparedStatement can make the code more readable and maintainable compared to constructing SQL queries as strings with Statement.
4. Better Performance: PreparedStatement can be reused with different parameters, reducing overhead associated with parsing and optimizing SQL queries each time they are executed.
5. Automatic Escaping: PreparedStatement handles escaping of special characters automatically, reducing the risk of errors and SQL injection vulnerabilities.

Overall, using a PreparedStatement in JDBC provides a more secure, efficient, and maintainable way to interact with databases compared to using a Statement.
