Bridge Parameters
| Parameter Name | Description | Type | Values | Default | Scope | ||
| File | This bridge imports an XML file with DSV or XMLA extension. The file represents a data source view definition for Microsoft SQL Server 2005 Analysis Services. Two options are available to retrieve such a file: A) From SQL Server Business Intelligence Development Studio: Each project contains one or more files with dsv extension. Such file can be selected and exported with the command: "File->Save .dsv As ..." to generate the DSV file. Or the file can be found in the project directory. Each project contains one or more files with dsv extension. Such file can be selected and exported with the command: "File->Save .dsv As ..." to generate the DSV file. Or the file can be found in the project directory. B) From SQL Server Management Studio: SQL Server Management Studio can connect to an existing Analysis Services server, which contains a list of data source views. Choose a data source view to be saved and use the command:"Script database as->CREATE To -> File..." to generate a file with XMLA extension. |
