The && operator in SQL is used to combine multiple conditions in a single statement. An && operator returns a TRUE value only if both conditions are true.
For example, consider a table with the following columns: product_id, price, and quantity.
If you wanted to retrieve the product id, price, and quantity for all products that have a price and quantity greater than $10 and 500, respectively, then an && operator (in combination with the more structured SQL syntax) could be used to achieve this result.
The following query illustrates an example of how the && operator could be used in an SQL statement:
SELECT product_id, price, quantity
FROM products
WHERE price > 10 && quantity > 500;
Essentially, this query will return all records that meet both conditions specified by the && operator – the price must be greater than $10 and the quantity must be greater than 500.
Ultimately, the && operator can be seen as a shorthand way of combining multiple conditions into a single statement.
