WinSCP hangs up when connecting to database

Hello,
I'm trying to connect to my database with this code : I put it in the terminal, execute and then it hangs up, I waited over 5mins and nothing and had to close winSCP with the task manager since it froze.
Any help on this?
Thank you.

WinSCP does not support commands that require user input. You can use mysql only if you provide your SQL query on command line.
