18. Something to watch out for
The INSERT statement we use assume that the order of the values is the same as the order of fields in the CREATE TABLE statement.
If this were not the case you can use Excel to change the order of the columns.

19. Proceed Create an Item table (don’t forget a primary key).
Insert the item data.
Create a table for the order. Note that “Order” is not an acceptable name for a table in Oracle – so change it. Also note that “Date” is a type and should not be used as the name of a field. Don’t forget the order table has foreign keys.

Our procedure added single quotes but when we have numbers we do not want the quotes.
