Select the name column from the Products table for products whose quantity is not equal to 25 using the NOT operator.

To select the name column from the Products table for products whose quantity is not equal to 25 using the NOT operator, you would use the following SQL query:

SELECT name 
FROM Products 
WHERE NOT(quantity = 25);

Here's the step by step breakdown:

1. SELECT name: This part of the query selects the 'name' column from the table. You can replace 'name' with any column you want to select.

2. FROM Products: This part of the query specifies the table you are selecting from, in this case, the 'Products' table.

3. WHERE NOT(quantity = 25): This is the condition for selecting the rows. It selects the rows where the 'quantity' column is not equal to 25. The 'NOT' operator negates the condition that follows it.
