[All DEA-C01 Questions]

A Data Engineer needs to know the details regarding the micro-partition layout for a table named invoice using a built-in function.

Which query will provide this information?

Show Suggested Answer Hide Answer
Suggested Answer: C

This option is the best way to transform relational data into semi-structured data using the least amount of operational overhead. The OBJECT_CONSTRUCT function takes a variable number of key-value pairs as arguments and returns a Snowflake object, which is a variant type that can store JSON data. The function can be used to convert each row of relational data into a JSON object with the column names as keys and the column values as values.

I bet the answer is 'SELECT * FROM INVOICE WHERE PARTITION_ID = 42' - you know, the answer to the ultimate question of life, the universe, and everything.

Wait, is this a trick question? What if the correct answer is actually 'SELECT FROM INFORMATION_SCHEMA.PARTITIONS WHERE TABLE_NAME = 'Invoice'?

Hmm, SYSTEM$CLUSTERING_INFORMATION seems more official than $CLUSTERXNG_INFQRMATION. I'll go with C.

A and B seem a bit off, like they were typed by someone who was half-asleep. I'm leaning towards C or D.

Option C looks the most promising, but I'm not sure about the function name. Might want to double-check the spelling.
