In last sql post we leaned LIKE Operator and IN Operator and BETWEEN Operator. In this sql tutorial we will learn SQL AND & OR Operator with syntax and example.

The AND Operator Syntax :

SELECT col1, col2,col3 FROM table_name WHERE col1 = val1 AND col2 = val2 AND col3=val3

In above sql statement returns records, if they satisfy all the three WHERE condition.

The AND Operator Example  :

Here, we have table Student with below records.

The SQL Student Table :

ID Name City Email
1 Meera Bombay meera@yahoo.com
2 Ram Surat ram@yahoo.com
3 Manoj Bombay manoj@yahoo.com
4 Vaidehi Ahmedabad meera@yahoo.com

SELECT * FROM Student WHERE ID=1 AND Name=’Meera’

The SQL AND Operator Example Result is :

ID Name City Email
1 Meera Bombay meera@yahoo.com

 

The SQL OR Operator  Syntax:

SELECT col1, col2,col3 FROM table_name WHERE col1 = val1 OR col2 = val2 OR col3=val3

The OR Operator Example  :

Here, we have table Student and we want to select records whose id is 1 or city is ‘Surat’

SELECT * FROM Student WHERE ID=1 OR City = ‘Surat’
