What does it mean when SQL handles command line errors

It means that you are having problems writing your statements,

This can easily happen. Most of them are due to symbolic problems. There are also some of your keywords written wrong

such as FROM accidentally written FORM, etc., the specifics of the statement you have to post, I will help you to see!
