OR condition in SQLite

SQLite OR
To make multiple comparisons with different operators in the same statement, the SQLite OR clause is used. It is generally used with SELECT, UPDATE and DELETE statements. In the case of OR operation, if any of the given condition is true, the complete condition is considered true. It is always used with the WHERE Clause.

Syntax:

SELECT column_1, column_2, column_N   
FROM table_name  
WHERE condition_1 OR condition_2...OR condition_N;   

Example:
TEACHERS Table:

ID NAME AGE SUBJECT
1 Jim 27 English
2 John 30 Geology
3 Watson 28 French
4 Holmes 40 Chemistry
5 Tony 35 Physics
SELECT * FROM TEACHERS
WHERE ID > 2 OR AGE >= 30;

Output:

ID NAME AGE SUBJECT
2 John 30 Geology
3 Watson 28 French
4 Holmes 40 Chemistry
5 Tony 35 Physics

Explanation:
The “TEACHERS” is an already existing table. Here we are selecting those rows of the table where either the value in the ID column is greater than 2 or the value in the AGE column is greater than or equal to 30 or where both the conditions are true.
