We use the select *query to show all the table contents. Upon Successful Execution, your screen will look like this: To insert values, we will use the insert command. Now we will insert the values in our table. On Successful execution, your screen will look like In our case query will be as follows: create table Article( We will create an Article table with two fields, Author and Word Length. Your database will be created as shown below: create database įor instance, we will name our database as CSharp_Articles, i.e., create database CSharp_Articles Īfter that, click on the GO button at the bottom right of the page. STEP 5. First, we will create a database and type the following query. Now open any browser, ensure you’re connected to the internet, and navigate to STEP 4.
