The virtual table (XXXXTableName) data model I created tried to set "mid" as the primary key constraint, but it was invalid，I want to use "mid" as the primary key so that the inserted data does not duplicate, how do I set it?

I see that the table inside DB(XXXXTableName_content) actually uses the private property "docid" as the primary key.
