The Mapping property maps a database column to an entry in the OrderForm or Dictionary object that the DBStorage object uses to insert and retrieve data.
Definition
Property Mapping As Object
Parameters
None.
Error Values
This method sets the Number property of the global Err object to S_OK (&H00000000) to indicate success and to standard COM error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object. In particular, the Description property may contain a text description of the error.
Remarks
A mapping Dictionary object makes it possible to map the column names in a database table to one or more names that you choose, usually for display to the site user. Suppose, for example, that your database table contains a column named "shopper_name", but that you want to display the contents of this column as the more human-readable "Shopper Name". Consequently, you initialize a "shopper_name" key in a Dictionary object to "Shopper Name", and use this object to set the Mapping property. When you call a DBStorage object data retrieval method, such as GetData, to read a row of data into a Dictionary object, the Dictionary key for the "shopper_name" column reads "Shopper Name". This new mapping means that you do not have to translate the column name to a more human-readable name before displaying its values to the site user. You can simply display the keys and values as they appear in the Dictionary object returned by the GetData method.
