Review Summary
Good job structuring the database schema with the correct tables and columns. However, I'm requesting changes because the script contains several critical syntax errors that prevent it from executing, which caused the build to fail.
Specifically, please address these issues:
- Missing Commas: Remember to separate all column and constraint definitions within a
CREATE TABLEstatement with a comma (,). - Missing Semicolons: Each
CREATE TABLEstatement must end with a semicolon (;). - Incorrect Foreign Key: In the
OrderItemstable, the foreign key that links to theProductstable is incorrect. It should reference theProductIDcolumn within theOrderItemstable, not the table nameProducts.
Fixing these syntax issues should get your script working correctly. You're on the right track!

This CREATE TABLE statement has some syntax errors that are repeated in the other tables. Remember to separate all column and constraint definitions with commas, and to end the entire statement with a semicolon (;).

The FOREIGN KEY must refer to a column in the current table (OrderItems). To link to the Products table, you should specify the ProductID column here, not the table name Products.

Review Summary
Great work on this SQL script! It's well-structured, functional, and meets all the core requirements, so I am approving your solution. One minor suggestion for the future is to match the casing for identifiers exactly as specified in the requirements (e.g., Name instead of NAME). While this doesn't affect functionality here, it's a good practice for consistency and portability. Overall, excellent job!

The requirement specifies this column should be named Name. While SQL is often case-insensitive for identifiers, it's best practice to match the naming in the requirements exactly to ensure portability and consistency.
