SQLite UPDATE Query

In SQLite, UPDATE query is used to modify the existing records in a table. It is used with WHERE clause to select the specific row otherwise all the rows would be updated.

Syntax:

UPDATE table_name  

SET column1 = value1, column2 = value2...., columnN = valueN  

WHERE [condition]; 

Example:

We have an existing table named “STUDENT”, having the following data:

Example1:

Update the ADDRESS of the student where ID is

UPDATE STUDENT SET ADDRESS = 'Noida' WHERE ID = 1;   

Now the address is updated for the id 1. You can check it by using SELECT statement:

SELECT * FROM STUDENT;  

Output:

Example2:

If you don’t use WHERE clause, it will modify all address in the STUDENT table:

UPDATE STUDENT SET ADDRESS = 'Noida';   

Output:
