<Defaults>
<Defaults> is an optional child of the <DataImport> element. Like the <Metadata> element, it can be used to define constants for use in the mapping file. It has one or more <Default> elements as children.
<Default>
Each <Default> element defines a specific default value. Note that you can use either a defaults or metadata items to define constants. The only difference is that a metadata item uses a Name attribute as the key, and a default uses an Id attribute.
This table describes each attribute of the <Default> element.
| Attribute | Description |
|---|---|
| Id | ID used to refer to the default. Required. |
| Type | Data type of the default. All .NET types are supported. The import processor will attempt to cast the default to this type, but will return an error if there is a type mismatch. For example, an integer can be cast as a string, but a string can’t be cast as an integer. |
| Value | Value of the default. Required. |
