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:
