Will the IsEmpty() function evaluate blank values?

1. Yes, it evaluates blanks.

2. No, it does not.

3. Only for numeric fields.

4. Only when combined with isNull().

The correct answer is: Yes, it evaluates blanks.

The IsEmpty() function is designed to evaluate whether a given value is empty or blank. This means that it checks for situations where there is no data present, which includes strings that consist only of whitespace characters or are completely devoid of any content. Therefore, when you apply the IsEmpty() function to a field or value, it will return a result indicating if that field is blank or not. In practical terms, if you are working with a dataset that includes fields where some records might not contain any data (such as empty text fields), using the IsEmpty() function will effectively help identify those blank entries. It is useful for data validation or cleaning processes, where you want to filter out or flag records that do not have meaningful data. The other options propose limitations on the function's capabilities, such as only applying to numeric fields or needing to be used in conjunction with isNull(), which does not align with the intended usage of the IsEmpty() function. In contrast, the function is versatile and works uniformly across various data types, including strings and potentially blank values. This is why the assertion that it evaluates blanks is indeed correct.
