The values of the respective tuple are the data items separated by commas.
If new values are to be entered for certain attributes but not for all, the respective columns must be indicated explicitly; the remaining columns are filled with null values.
Demonstration
Below is an SQL test area from W3Schools, which uses the well-known Northwind sample database.
The tables here are for read only because of the problem of embedding the scripts.
For a fully working example, check this by using Chrome.
Result:
The Database includes:
Tablename
Record
Customers
91
Categories
8
Employees
10
OrderDetails
518
Orders
196
Products
77
Shippers
3
Suppliers

This SQL-Statement is not supported in the WebSQL Database.
The example still works, because it uses a modified version of SQL.
Your browser does not support WebSQL.
Your are now using a light-version of the Try-SQL Editor, with a read-only Database.
If you switch to a browser with WebSQL support, you can try any SQL statement, and play with the Database as much as you like. The Database can also be restored at any time.
Our Try-SQL Editor uses WebSQL to demonstrate SQL.
A Database-object is created in your browser, for testing purposes.
You can try any SQL statement, and play with the Database as much as you like. The Database can be restored at any time, simply by clicking the "Restore Database" button.
W3C WebSQL
WebSQL stores a Database locally, on the user's computer. Each user gets their own Database object.
WebSQL Browser Support
WebSQL is supported in Chrome, Safari, and Opera.
If you use another browser you will still be able to use our Try SQL Editor, but a different version, using a server-based ASP application, with a read-only Access Database, where users are not allowed to make any changes to the data.
