Which parameter is not typically associated with the dimension duration type?

• A. sql_start
• B. sql_end
• C. intervals
• D. sql_type

Answer: (D)

The dimension duration type in Looker is specifically designed to represent time intervals or durations. The parameters typically associated with this type are focused on defining the start and end points of the duration and specifying how the dimensions are calculated. The parameter `sql_start` is used to define the start of the duration, while `sql_end` indicates the endpoint. These two parameters work together to establish the overall time frame being measured. The `intervals` parameter allows for more granular control over how those durations are divided, such as into days, months, or years. In contrast, the `sql_type` parameter is used to specify the SQL type of the dimension but is not specifically tied to the functionality or definition of duration dimensions. Instead, it generally applies to dimensions of any type to indicate how the underlying database should interpret the data type. Therefore, it does not directly relate to the unique characteristics of time duration, making it the correct choice for this question.
