INSERT statement is missing WarehouseName column but VALUES includes CountryID which wasn't specified in columns. Column list should be: (ID, WarehouseAmount, WarehouseName, WarehouseAddress, CountryID)

Same issue as line 48 - WarehouseName is missing from column list but appears in VALUES. Also, WarehouseAddress in VALUES doesn't match the column order.

INSERT attempts to insert without specifying ID column, relying on auto-increment. However, WarehouseName is still missing from column list. Also CountryID value doesn't match the column position.

| VALUES (2, 5, 'Warehouse-2', 'City-2', 2); |

ID = 2 is already used in line 50. This creates a primary key conflict. Also WarehouseName and WarehouseAddress positions don't match column list order (WarehouseAmount, WarehouseName, WarehouseAddress).
| INSERT INTO ProductInventory (ID, ProductID, WarehouseID) | ||
| VALUES (1, 1, 1); |

The ProductInventory INSERT only creates one record. The test data should represent the original non-normalized data (which likely had multiple products across warehouses). Consider what test data the original structure would have held.

Review Summary
The database schema is correctly normalized to third normal form (3NF) with proper decomposition into Product, Warehouse, and ProductInventory tables. Foreign key relationships are correctly defined, and the structure meets all requirements. Minor data quality issues such as duplicate product names and missing AUTO_INCREMENT or NOT NULL constraints do not affect the validity of the schema for the task.
