The MySQL OR condition specifies that if you take two or more conditions then one of the conditions must be fulfilled to get the records as result.
WHERE condition1 OR condition2 ... OR condition_n;
condition1, condition2, ... condition_n: Specifies all conditions that must be fulfilled for the records to be selected.
The following example specifies how to use the OR condition in MySQL with SELECT statement.
Consider a table "cus_tbl", having the following data:
Execute the following query:
SELECT * FROM cus_tbl WHERE cus_firstname = 'Ajeet' OR cus_id > 100;
Note: In the above example you can see that the second condition "cus_id" is wrong but the query is displaying the correct result because of the OR condition.
