SqlParameter.SourceColumn Property


Gets or sets the name of the source column mapped to the DataSet and used for loading or returning the Value

 property System::String ^ SourceColumn { System::String ^ get(); void set(System::String ^ value); };
public string SourceColumn { get; set; }
member this.SourceColumn : string with get, set
Public Property SourceColumn As String

Property Value

The name of the source column mapped to the DataSet. The default is an empty string.




The following example creates a SqlParameter and sets some of its properties.

static void CreateSqlParameterSourceColumn()
    SqlParameter parameter = new SqlParameter("Description", SqlDbType.VarChar, 88);
    parameter.SourceColumn = "Description";
Private Sub CreateSqlParameterSourceColumn()
    Dim parameter As New SqlParameter("Description", SqlDbType.VarChar, 88)
    parameter.SourceColumn = "Description"
End Sub


When SourceColumn is set to anything other than an empty string, the value of the parameter is retrieved from the column with the SourceColumn name. If Direction is set to Input, the value is taken from the DataSet. If Direction is set to Output, the value is taken from the data source. A Direction of InputOutput is a combination of both.
