MySQL UPDATE

The MySQL UPDATE Statement

The UPDATE statement is used to modify the existing records in a table.

Syntax:

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

Warning! Be careful when updating records. If you omit the WHERE clause, ALL records will be updated!
