No need to abuse me with words, & be judgemental without knowing the full story.
FYI, I was about to provide you with the exact db command (in fact the answer was already typed into the forum screen), but Warren beat me to it. I had spent time reading the wiki article too, on your behalf.
As the question had been answered, I then decided to advise you "for your own benefit & good", re where you could find the information that would assist you to learn the correct syntax knowledge for using the db command in all situations, rather than continuing to guess for specific cases that arise.
...someday I too maybe able to help others in the same situation.
Reading those tutorials will go a long way to assisting you in that endeavour, but you will need to improve your manners & appreciation of peoples efforts, without jumping to conclusions.
