Final answer:
The SQL statement MONTH(PurchaseDate) extracts the month from the PurchaseDate column as an integer between 1 and 12.
Step-by-step explanation:
The statement MONTH(PurchaseDate) in SQL for SQL Server is used to extract the month part from a date. When this function is applied to a date column like PurchaseDate, it returns an integer value representing the month part of that date, which falls between 1 and 12, where 1 represents January and 12 represents December. This function can be particularly useful when you want to perform aggregations or comparisons by a month or generate reports based on a monthly cycle.
