Updating into string
Not allowed when a Number field is part of a relationship.If the original value is in the form of a valid Internet Protocol (IP) address (four number triplets separated by a period: nnn.nnn) and the numbers happen to coincide with a Web address, the conversion results in a valid link.Top of Page If you're comfortable working with SQL, you can also write an UPDATE statement by using SQL view.To use SQL view, create a blank, new query, and then switch the SQL view.Remember that Access stores all dates as serial dates, and it stores the date values as double-precision floating integers. Dates outside the range April 18, 1899 and September 11, 1900 exceed the size of a Byte field.Dates outside the range April 13, 1810 and September 16, 1989 exceed the size of an Integer field.To accommodate all possible dates, set the Field Size property of your Number field to Long Integer or greater.Values must not exceed (or fall below) the size limit set for the field.
You cannot undo the results of an update query, and making a backup helps make sure that you can reverse your changes if you change your mind.
You can think of update queries as a powerful form of the Find and Replace dialog box.
You cannot use an update query to add new records to a database, or to delete records from a database.
For that reason, you decide to update the Customers table with the data from the Clients table.
As you continue, remember that although the data types for each table field do not have to match, they must be compatible.
