For a more in-depth explanation, pleas view my LeetCode solution: https://leetcode.com/problems/recyclable-and-low-fat-products/solutions/3563813/recyclable-and-low-fat-products-simple-logical-sql-command/

Intuition

The problem is to find the product ids of products that are low in fats and recyclable from a table called Products. A possible way to solve this problem is to use a SQL query that filters the rows based on the low_fats and recyclable columns.

Approach

1. Write a SELECT statement that specifies the product_id column as the output.
2. Write a FROM clause that specifies the Products table as the source.
3. Write a WHERE clause that specifies the conditions for low_fats and recyclable columns. Use the AND operator to combine the two conditions.
4. Run the query and return the result.

Complexity

• Time complexity: O(n)
  The SQL query iterates over all of the items in the `Product table to check if they match the clauses.

• Space complexity: O(1)
  No additional storage is necessary for the SQL query.

Code

sql
SELECT product_id FROM Products WHERE low_fats='Y' AND recyclable='Y';
