Use the Data Provider editor Interface tab to define the input parameters and default settings for the external system and specify the provider class and cache settings.
Field | Use |
---|---|
Parameters | When you create a new data provider, Design Studio displays all of the mandatory and optional parameters based on the selected provider type. Mandatory parameters are shown with an asterisk (*) to differentiate them from optional parameters.
Click Add to add an input parameter, and select the new parameter to rename it. Input parameters specify named parameters whose values are used when retrieving an external instance. The value is determined at run time and is based on the XPath or XQuery expression you define in the Default Value field. |
Default Value | Define the content of the associated parameter element as an XPath to a node or as an XQuery expression.
|
Result Document | (Optional) Specify the structure of the XML document. Though this field is optional, if you do not provide an XML structure, the system will not display the parameters on the Data Instance Behavior Properties tab. |
Note:
XPath and XQuery fields are limited to 4000 characters
