PreparedStatement pstmt = con->prepareStatement("UPDATE employees SET salary = ? WHERE name = ?"); pstmt->setInt32(1, 50000); pstmt->setString(2, "John"); pstmt->executeUpdate();
PreparedStatement pstmt = con->prepareStatement("INSERT INTO users (username, password) VALUES (?,?)"); pstmt->setString(1, "johndoe"); pstmt->setString(2, "password123"); pstmt->executeUpdate();In this example, we are inserting a new user into the users table using a prepared statement. The setString() method is used to set the values of the two parameters (username and password). The package library for PreparedStatement is the JDBC package, specifically the C++ implementation of it. It provides a set of classes for connecting to and working with databases using the Java Database Connectivity (JDBC) API.
