Scenario: If you change the column name in a create table migration file, do you need to change the column name in the model file that represents the table? Yes No CREATE TABLE nail_polishes ( id INTEGER PRIMARY KEY AUTOINCREMENT, tag_name VARCHAR(255), barcode INTEGER, color VARCHAR(255), opacity FLOAT ); SELECT barcode FROM nail_polishes WHERE opacity >0.5 AND color LIKE 'B\%; 2. Based on the database schema and SQL query above, there is ONLY ONE index that you can choose below that will improve the SQL query. Choose the correct one. CREATE INDEX idx_nail_polishes_color_opacity oN nail_polishes(color, opacity); CREATE INDEX 1dx_nail_polishes_barcode_color ON nail_polishes(color); CREATE INDEX idx_nail_polishes_opacity_color_tag_name oN nail_polishes(opacity, color, CREATE INDEX 1dx_nail_polishes_barcode_opacity_color oN nail_polishes(barcode, No index listed will make this query more efficient
