Параметры

  • restrictions
    Тип array<System. . :: . .Object> [] () [] []
    An array of Object objects that specifies the values for the restriction columns that are used by the schema table. 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.
  • 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 rowset.

Замечания

If throwOnInlineErrors is true, this method behaves identically to GetSchemaDataSet.If throwOnInlineErrors is false, and there are errors that occur while retrieving schema information, the resulting DataSet may contain null Nothing nullptr unit пустая ссылка (Nothing в Visual Basic) cells that would not normally be null Nothing nullptr unit пустая 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.
