True or False: The SQL expression for type: yesno dimensions can include aggregations.

True or False: The SQL expression for type: yesno dimensions can include aggregations.

• A. True
• B. False
• C. Only in advanced settings
• D. Only in table calculations

Answer: (B)

Type: yesno dimensions in Looker are designed to represent boolean values, typically interpreted as true or false. In LookML, these dimensions derive their values directly from the underlying data without requiring aggregations within the SQL expression. The structure of a yesno dimension often results from evaluating a specific condition or expression within the database, and its intent is to provide a simple true or false response. Aggregations, on the other hand, are operations that summarize data, such as counting how many times a certain condition is met or calculating averages. Incorporating aggregations within a yesno dimension would complicate its function and disrupt its purpose, which is to yield straightforward boolean outcomes rather than calculated summaries of data. Thus, it is accurate to state that the SQL expression for type: yesno dimensions cannot include aggregations, confirming that the correct answer is false.
