Question

What is the SQL command to break apart an array's elements into individual rows to operate over each row?

Answer 1

The SQL command to break apart an array's elements into individual rows is UNNEST(). This command allows you to transform an array into a set of rows, where each element of the array becomes a separate row.

Step-by-step explanation:

The SQL command to break apart an array's elements into individual rows is UNNEST(). This command allows you to transform an array into a set of rows, where each element of the array becomes a separate row. You can then perform operations on each row individually.

For example, if you have an array ['apple', 'banana', 'orange'], using the UNNEST() command will result in:

• apple
• banana
• orange

This allows you to apply functions or manipulate the data for each element in the array individually.
