Question
Which of the following SQL statements correctly converts the product_name column in the products table to lowercase and displays it as lowercase_name? This question is required.*ASELECT LOWER(productname) AS lowercasename FROM products;BSELECT productname AS lowercasename FROM products WHERE productname = LOWER(productname);CSELECT productname AS LOWER(productname) FROM products;DSELECT productname AS lowercasename FROM products;
Solution
The correct SQL statement is A.
Here's why:
A) SELECT LOWER(product_name) AS lowercase_name FROM products;
This statement correctly uses the LOWER() function to convert the product_name column to lowercase. It then renames this column as lowercase_name using the AS keyword.
B) SELECT product_name AS lowercase_name FROM products WHERE product_name = LOWER(product_name);
This statement is incorrect because it only selects rows where the product_name is already in lowercase. It does not convert all product_name entries to lowercase.
C) SELECT product_name AS LOWER(product_name) FROM products;
This statement is incorrect because it attempts to rename the product_name column as LOWER(product_name), which is not a valid column name.
D) SELECT product_name AS lowercase_name FROM products;
This statement is incorrect because it does not convert the product_name column to lowercase. It only renames the column as lowercase_name.
