Invalid column name in lesson 258-2 and 258-3

Screen Link:


Column “schemaname” is not a column in table “information_schema.tables”. The name should actually be “table_schema”. The wrong column name appears once on “Investigating the tables” and three times in “Working with schemas”.

Where has it been stated that schemaname is a column in information_schema.tables? Sorry, it’s unclear what your question really is here.
