SnowPro Advanced: Data Engineer — Question 52

Which callback function is required within a JavaScript User-Defined Function (UDF) for it to execute successfully?

Answer options

• A. initialize()
• B. processRow()
• C. handler()
• D. finalize()

Correct answer: B

Explanation

The correct answer is B, as the processRow() function is specifically designed to handle the processing of each row in a UDF. The other options, while they may have their own purposes, do not fulfill the requirement for row processing within the UDF context.
