Which of the following code blocks will remove the rows where the value in column age is greater than 25 from the existing Delta table my_table and save the updated table?

Show Suggested Answer Hide Answer
Suggested Answer: C

: The DELETE command in Delta Lake allows you to remove data that matches a predicate from a Delta table. This command will delete all the rows where the value in the column age is greater than 25 from the existing Delta table my_table and save the updated table. The other options are either incorrect or do not achieve the desired result. Option A will only select the rows that match the predicate, but not delete them. Option B will update the rows that match the predicate, but not delete them. Option D will update the rows that do not match the predicate, but not delete them. Option E will delete the rows that do not match the predicate, which is the opposite of what we want.Reference:Table deletes, updates, and merges --- Delta Lake Documentation

Hmm, I'm torn between B and C. But I think C is the safer bet since it's a direct delete operation.

I'm going with C as well. Deleting the rows is the most straightforward way to update the table.

Option C is the correct answer. It will delete the rows where the age is greater than 25 from the existing Delta table my_table.

That makes sense. It will remove the rows we don't need.
