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.

Example

[Visual Basic, C#, C++] The following example creates an OdbcParameter and sets some of its properties.

[Visual Basic] 
Public Sub CreateOdbcParameter()
    Dim myParameter As New OdbcParameter("Description", OdbcType.VarChar, 88)
    myParameter.SourceColumn = "Description"
    myParameter.SourceVersion = DataRowVersion.Current
End Sub 'CreateOdbcParameter

[C#] 
public void CreateOdbcParameter() 
 {
    OdbcParameter myParameter = new OdbcParameter("Description", OdbcType.VarChar, 88);
    myParameter.SourceColumn = "Description";
    myParameter.SourceVersion = DataRowVersion.Current;
 }

[C++] 
public:
    void CreateOdbcParameter()
    {
        OdbcParameter* myParameter = new OdbcParameter(S"Description", OdbcType::VarChar, 88);
        myParameter->SourceColumn = S"Description";
        myParameter->SourceVersion = DataRowVersion::Current;
    };
