How to cancel wrong command in MySQL?

When using MySQL, sometimes I accidentally enter the wrong command when entering it, but find that I cannot exit the error state. So, how can you cancel the wrong command?

1. Common command line errors

1. First, you must find out the cause of the error. Common causes of errors are:

1) Forgot to enter the semicolon at the end.

2. The ' character

#3) The " character was entered incorrectly.

2. Solution

1. When an incorrect command cannot be exited, in most cases it is because MySQ believes that the command line has not ended yet. In this case, sometimes even if you type quit, you will not be able to exit. Common mistakes, the solutions are:

2) Since the ' and " signs appear in pairs in MySQL, when you type the ' or " sign incorrectly, you need to complete the other half to exit #.

##3) After exiting, you only need to enter the correct command again to execute it.

##Notes

When you enter '," incorrectly, you must type the other half to exit the command.
