getComparisonValue

                                           java.lang.String compValue)

Takes a String from ArraySQL and converts it to the appropriate data type based on the comparison value. For example mydate='04/12/04' would know that the string should be converted to a date based on the fact that the data it is being compared to is a date. If the data in mydate was a String then a String comparison object would be returned, not a Date
