Параметры
- schemaName
Тип: System.String
The name of the schema to be retrieved.
- schemaNamespace
Тип: System.String
The name of the schema namespace to be retrieved.
- restrictions
Тип: Microsoft.AnalysisServices.AdomdClient.AdomdRestrictionCollection
A collection of AdomdRestriction objects that specifies the values for the restriction columns used by the schema table.
- throwOnInlineErrors
Тип: System.Boolean
If true, inline errors cause an exception to be thrown; otherwise DataRow.GetColumnError is used to determine the error generated.
Возвращаемое значение
Тип: System.Data.DataSet
A DataSet that represents the contents of the specified OLE DB schema table.
Замечания
If throwOnInlineErrors is true, this method behaves identically to GetSchemaDataSet. If throwOnInlineErrors is false, and errors occur while retrieving schema information, the resulting DataSet may contain nullпустая ссылка (Nothing в Visual Basic) cells that would not normally be nullпустая ссылка (Nothing в Visual Basic). To determine the details of the errors that occur, you can use the DataRow.GetColumnsInError, DataRow.GetColumnError, DataRow.HasErrors, DataSet.HasErrors, and DataTable.HasErrors methods and properties.
