You have a table named 'ORDERS' with a column 'ORDER DATE of data type DATE. You need to write a SQL query to retrieve all orders placed in the month of January 2023. Which of the following queries is the MOST efficient way to achieve this in Snowflake?
Correct Answer: B
Using a 'BETWEEN' operator with specific date values (Option B) is generally the most efficient way to filter data based on a date range in Snowflake. It allows Snowflake to utilize indexing (if available) and optimize the query execution plan. Options A and D, using functions like 'MONTH' and 'YEAR' or 'DATE_PART , prevent index usage and require Snowflake to evaluate the function for every row. Option C, converting the date to a string using `TO_CHAR , is also inefficient for the same reason. Option E, using `LIKE', is unsuitable for date comparisons and would not be performant, and could also potentially return incorrect results.
