/**
* This tests the use of an arbitrary converter. The column
* converted is a VARCAHAR. ResultSetShape is used to specify
* that the property will be a
* SDODataTypes.DATE.
*
* So this example uses a converter that transforms a string column
* into a date property and conversely, a date property back to a string for the
* underlying column.
*
* The converter returns 1957.09.27 if the column value is "Williams"
* and 1966.12.20 if the value is "Pavick"
*
* On write, the converter returns "Pavick" if the property value is
* 1966.12.20 and "Williams" if the property value is 1957.09.27
