Параметры

schema
Тип System. . :: . .Guid
A Guid object that specifies the schema table to be returned.

restrictions
Тип array<System. . :: . .Object> [] () [] []
An array of Object objects that specifies the values for the restriction columns that the schema table uses. These values are applied in the order of the restriction columns. That is, the first restriction value applies to the first restriction column, the second restriction value applies to the second restriction column, and so on.

Возвращаемое значение

Тип System.Data. . :: . .DataSet
A DataSet that represents the contents of the specified OLE DB schema rowset.

Замечания

The schema rowset is returned as a DataSet that has the same format as the OLE DB schema rowset specified by the schema parameter. Use the restrictions parameter to filter the rows to be returned in the DataSet. (For example, you can specify restrictions for table name, type, owner, or schema). When you pass values in the array, include empty strings or nulls for array elements that do not contain values. If you pass an empty array to restrictions, all rows are returned in default order. Values in the array correspond to the order of the columns in the OLE DB or OLE DB for OLAP specifications.

If a Guid is provided that is not associated with a schema rowset, or if the schema rowset associated with the provided Guid is not supported by the server, the InvalidOperationException exception is thrown. Similarly, an exception is thrown if an error occurs while retrieving the schema rowset from the provider.

The AdomdSchemaGuid contains a collection of Guid objects that represents the most commonly supported OLE DB and XML for Analysis schema rowsets.
