Statements types in JDBC course,
in this course we will learn about the Statements types in JDBC, which are crucial for interacting with databases in Java applications. JDBC (Java Database Connectivity) provides three main types of statements: Statement, PreparedStatement, and CallableStatement. Each type serves a specific purpose and is suited for different scenarios.
Statement: This is used for executing simple SQL queries without parameters. It's ideal for executing static queries, such as retrieving data or performing basic database operations. We'll cover how to create and use a Statement object to execute SQL commands and process the results.
PreparedStatement: This type is used for executing parameterized SQL queries. PreparedStatements are precompiled, which improves performance and security by preventing SQL injection attacks. We'll explore how to set parameters dynamically, execute queries, and handle the results efficiently. PreparedStatements are particularly useful for repeated execution of SQL statements with varying parameters.
CallableStatement: This is used to execute stored procedures in the database. Stored procedures can encapsulate complex logic and return multiple results, making them powerful tools for database interactions. We'll learn how to call stored procedures, pass parameters, and handle the returned results.
