Certified Data Engineer Associate Exam - Question 100


Which command can be used to write data into a Delta table while avoiding the writing of duplicate records?

Show Answer
Correct Answer: C

MERGE is the correct command to use for writing data into a Delta table while avoiding the writing of duplicate records. Unlike INSERT or APPEND, which simply add records to the table, MERGE allows you to specify conditions for updating existing records and inserting new records, ensuring no duplicates are written.
