07 Statement in JDBC | Insert & Search Data using User Input | Java Database Connectivity (JDBC)
This is the 7th video in our JDBC series.
Till now, we have learned how to fetch data from the database using ResultSet.
But in real-world applications…
👉 We don’t just fetch data,
we also take input from users and store it in the database.
In this video, we will learn how to use Statement to insert and search data using user input.
We will also understand when to use executeQuery(), executeUpdate(), and how queries are executed internally.
Along with that, we will implement everything step-by-step in a simple and beginner-friendly way.
