MySQL OR Operator
The OR operator in MySQL is used to combine multiple conditions in a SELECT, INSERT, UPDATE, or DELETE statement, and returns true if any of the conditions are true.
The syntax for using the OR operator in a SELECT statement is as follows:
SELECT column1, column2, ...
FROM table_name
WHERE condition1 OR condition2 OR ...;Here’s an example:
SELECT * FROM customers
WHERE city = 'New York' OR city = 'London';Table structure Used for Example explanation
