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.
