That's because you're just following a video that provides one specific example instead of doing proper research. If you did some research on SQL and read some documentation and proper tutorials instead of just watching videos then you'd learn how to write an INSERT statement. 这里's a good place to start. One click on the link for the INSERT statement and there's your answer. If you rely on YouTube videos then you will learn very little. Ii suggest that you do some proper research on any area you wish to learn.
