Examples

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

Public Sub CreateOdbcParameter()  
    Dim parameter As New OdbcParameter("Description", OdbcType.VarChar, 88)  
    parameter.SourceColumn = "Description"  
    parameter.SourceVersion = DataRowVersion.Current  
End Sub

public void CreateOdbcParameter()   
 {  
    OdbcParameter parameter = new OdbcParameter("Description", OdbcType.VarChar, 88);  
    parameter.SourceColumn = "Description";  
    parameter.SourceVersion = DataRowVersion.Current;  
 }

Remarks

The SourceVersion is used by UpdateCommand during an Update operation to determine whether the parameter value is set to Current or Original. This allows primary keys to be updated.

This property is set to the version of the DataRow used by either the Item property (DataRow indexer), or the GetChildRows method.
