The format for the UPDATE command is the word UPDATE, followed by the name of the table to be updated. The next portion of the command consists of the word SET, followed by the name of the column to be updated, an equals sign, and the new value.

Explanation:

An Update Query is an action query (SQL statement) that changes a set of records according to criteria you specify.
The SQL UPDATE Query is used to modify the existing records in a table. You can use the WHERE clause with the UPDATE query to update the selected rows, otherwise all the rows would be affected.
Update Queries let you modify the values of a field or fields in a table.

UPDATE Syntax 

UPDATE table_name
SET column1 = value1, column2 = value2, ...

table_name: name of the table
column1: name of first , second, third column....
value1: new value for first, second, third column....
