Assembly: System.Data (in

public override string SourceColumn { get; set; }

Property Value

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

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.

For more information about how to use the SourceColumn property, see Using Parameters with a DataAdapter and Updating the Database with a DataAdapter and the DataSet.

The following example creates an OleDbParameter and sets some of its properties.

[Visual Basic]

Public Sub CreateOleDbParameter()
    Dim parameter As New OleDbParameter("Description", OleDbType.VarChar, 88)
    parameter.SourceColumn = "Description"
End Sub 'CreateOleDbParameter


public void CreateOleDbParameter() 
    OleDbParameter parameter = new OleDbParameter("Description", OleDbType.VarChar, 88);
    parameter.SourceColumn = "Description";
