The MySQL AND Operator
The WHERE clause can contain one or many AND operators.
The AND operator is used to filter records based on more than one condition.
Note: The
ANDoperator displays a record if all the conditions are TRUE.
The following SQL selects all customers where country is "UK" AND city is "London":
Example
SELECT * FROM Customers
WHERE Country = 'UK'
AND City = 'London';
AND Syntax
SELECT column1, column2, ...
FROM table_name
WHERE condition1 AND condition2 AND condition3 ...;

WHERE Country = 'Germany'
AND (City = 'Berlin' OR City = 'Stuttgart');
