Microsoft SQL Server Getting started with Microsoft SQL Server UPDATE Specific Row
Example
UPDATE HelloWorlds
SET HelloWorld = 'HELLO WORLD!!!'
WHERE Id = 5
The above code updates the value of the field "HelloWorld" with "HELLO WORLD!!!" for the record where "Id = 5" in HelloWorlds table.
Note: In an update statement, It is advised to use a "where" clause to avoid updating the whole table unless and until your requirement is different.
