Méthode GetSchemaDataSet (Guid, Object[], Boolean)

Returns schema information from a data source by using a Guid object to identify the information, applying any specified restrictions on the information, and optionally throwing an exception when inline errors occur.

Syntaxe

'Déclaration
Public Function GetSchemaDataSet ( _
    schema As Guid, _
    restrictions As Object(), _
    throwOnInlineErrors As Boolean _
) As DataSet
'Utilisation
Dim instance As AdomdConnection
Dim schema As Guid
Dim restrictions As Object()
Dim throwOnInlineErrors As Boolean
Dim returnValue As DataSet

returnValue = instance.GetSchemaDataSet(schema, _
    restrictions, throwOnInlineErrors)

public DataSet GetSchemaDataSet(
    Guid schema,
    Object[] restrictions,
    bool throwOnInlineErrors
)

public:
DataSet^ GetSchemaDataSet(
    Guid schema, 
    array<Object^>^ restrictions, 
    bool throwOnInlineErrors
)

member GetSchemaDataSet : 
        schema:Guid * 
        restrictions:Object[] * 
        throwOnInlineErrors:bool -> DataSet

Paramètres

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

Valeur de retour

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

Notes

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 une référence Null (Nothing dans Visual Basic) cells that would not normally be null Nothing nullptr unit une référence Null (Nothing dans 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.
