Review Comment:
I think we can set remove the `global` property in `SetStmt` and than call
`executor.execute()` method. No need to create a new method `setSessionVars()`.

Review Comment:
This is error-prone, if other people at a new subclass of `SetVar`, this
method may be missed.
How about add a `SetVarType` or something to specify the stmt's type
directly?
And write like `return var.setType() == Type.SET_SESSION_VAR`;
