The Netbeans Java environment lets you create a connection to a database and retrieve records from the database to display in your Java forms. You can also add records to the tables using the Netbeans database connection. The database connection works throughout the total application and a Netbeans wizard helps you create a project connection to any database type.
1.Open the Netbeans software and open the Java project you want to use to connect to the database. When you open a project, a list of files and folders display in the left navigation panel.
2.Right-click the 'Java DB' node in the navigation panel and select 'Create Database.' A wizard window opens. Type a name for the database connection and a username and password to connect to the server. Select the location for the server or a server name and click 'OK' to make the connection.
3.Click the plus sign next to your database to view a list of tables. Right-click the table in which you want to add new records. Click the 'Execute Command' option. A window opens where you create your 'insert' SQL statement, which is the statement that inserts new data into tables.
4.Type your insert statement. For instance, if you want to insert a new customer record, type:
insert into customers (name) values ('joe campbell')
The statement above inserts a new customer with the name 'Joe Campbell' in the table data.
5.Click 'Run' to run the statement. If you want to verify that the table data inserted properly, right-click the table and select 'View All' to view the records.
