Assuming sometable is the same name in both schemas then the above will 
not work as:

https://www.postgresql.org/docs/current/sql-createview.html

"The name of the view must be distinct from the name of any other
relation (table, sequence, index, view, materialized view, or foreign
table) in the same schema."

You would get a conflict with the existing table MTQRY.sometable.

Though I noticed you have both MTQRY and MYQRY referring to the same 
thing, I think.
