Unzip 7zip to certain directory

I'm using this command line:

7z e d:devprojectsdbstestosc.data.db d:devprojectsdbstestosc.data.7z

I think the first parameter should be the output, and the 2nd paramater should be the input.

However, I switched them already, and none of my solutions would work.

Does anybody spot any errors?

Thank you!
