JDBC - Insert Records Example
how to insert/add records to a table using JDBC application. Before executing the following example, make sure you have the following in place −
To execute the following example you can replace the username and password with your actual user name and password.
Your MySQL or whatever database you are using is up and running.
Required Steps
The following steps are required to create a new Database using JDBC application −
Import the packages − Requires that you include the packages containing the JDBC classes needed for database programming. Most often, using import java.sql.* will suffice.
Open a connection − Requires using the DriverManager.getConnection() method to create a Connection object, which represents a physical connection with a database server.
Execute a query − Requires using an object of type Statement for building and submitting an SQL statement to select (i.e. fetch ) records from a table.
Extract Data − Once SQL query is executed, you can fetch records from the table.

ava MySQL INSERT example: Can you share a Java MySQL INSERT example, specifically using a Java PreparedStatement object?
Sure. As the question implies, you can use the Java Statement class to issue a MySQL INSERT statement, but the Java PreparedStatement class provides a much better way to insert data into a MySQL database table. (That being said, you can learn more about the Java Statement class in this Using SQL INSERT with Java Statement tutorial if you’re interested.)
A few of these MySQL fields are a little contrived, but I wanted to show several different data types in one table, so this is what I came up with. In particular, the field num_points is a little weird. I made it up so I could show a MySQL int data type in this table, and I was thinking of those websites where points are awarded for giving correct answers.
Other than that, this MySQL database table is relatively normal, though it is greatly simplified.
An example MySQL database table
The first thing we’ll need is an example MySQL database table. To keep it simple, but to also show several different MySQL data types, I created the following MySQL example database table:
