Which statements about the unique tool are false?

The unique tool is designed to identify distinct records in a dataset based on one or more specified columns. When considering the functionality of the unique tool, it's important to note that while you can select multiple columns for processing, there are practical limitations based on the data types and structure within your dataset. It’s not truly unlimited; rather, constraints exist that may arise from performance considerations or data structure, making the assertion of unlimited selection incorrect.

In terms of how the unique tool processes data, it does indeed operate top-down, which is consistent with how data is typically handled in various tools. The tool’s approach to case sensitivity is also critical; it can distinguish between uppercase and lowercase letters, meaning case sensitivity is an aspect the tool handles. Additionally, when producing a unique output, the tool prioritizes the first occurrence of each distinct entry, which aligns with the frequency of the values provided during processing.

Understanding these details emphasizes the tool’s capabilities and limitations regarding both column selection and data processing behavior.
