First you need to create a table named eg "Employee", then should use a command to insert details about it:
insert into Employee values (1, 'Alex', 'M', '1000');
And if you want to see how the table is going to look, here is the demo:
Once the data insertion is done, u need to put up a query,
Select * from Employee;
This is the output you are going to show, I hope it will.
