What are the advantages and disadvantages of using PreparedStatement compared to regular SQL queries?

PreparedStatement in Java has several advantages over regular SQL queries (Statement):

• Security: PreparedStatement helps prevent SQL injection because parameters are passed separately and are not interpreted as part of the SQL code.
• Performance: Queries with PreparedStatement are compiled once on the database side, which speeds up repeated execution with different parameters.
• Convenience: Allows easy substitution of parameters of different types without manually constructing the query string.

Disadvantages:

• Complexity for simple queries: For one-time or very simple queries, using PreparedStatement can be excessive.
• Potential overhead: In some cases, preparing the query takes additional time if the query is executed only once.

Example of using PreparedStatement:

String sql = "SELECT * FROM users WHERE id = ?";
PreparedStatement ps = connection.prepareStatement(sql);
ps.setInt(1, userId);
ResultSet rs = ps.executeQuery();
