Html table for updating database java
To take advantage of this, you need to configure a JDBC (Java Database Connectivity) database at this point.
You can verify what connections have been created by opening the Services window (Ctrl-5; ⌘-5 on Mac) and looking for connection nodes ( image::images/connection-node-icon.png ) under the Databases category. In Step 5, select To confirm that a new data source and connection pool are indeed registered with the Glass Fish server, you can deploy the project to the server, then locate the resources in the IDE’s Services window: Deployment descriptors are XML-based text files that contain information describing how an application is to be deployed to a specific environment.
We can just re-use the statement.execute Update("INSERT INTO Customers " "VALUES (1002, 'Mc Beal', 'Ms.', 'Boston', 2004)"); statement.execute Update("INSERT INTO Customers " "VALUES (1003, 'Flinstone', 'Mr.', 'Bedrock', 2003)"); statement.execute Update("INSERT INTO Customers " "VALUES (1004, 'Cramden', 'Mr.', 'New York', 2001)"); As you can see, this is pretty easy (once you've seen how it’s done).
