Parametri

  • restrictions
    Tipo: 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
    Tipo: System. . :: . .Boolean
    If true, inline errors cause an exception to be thrown; otherwise DataRow.GetColumnError is used to determine the error generated.

Valore restituito

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

Osservazioni

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 riferimento Null (Nothing in Visual Basic). cells that would not normally be null Nothing nullptr unit riferimento Null (Nothing in 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.
