Remarks
Unlike the CriteriaOperator.ToString method, the LegacyToString method removes value suffixes (such as ‘m’, ‘M’, ‘l’, ‘L’, ‘f’, ‘F’, etc.) used to specify types of numeric literals in criteria operands. You can call the LegacyToString method to display the returned string in a UI, or save it to an application log. However, this string is actually not in SQL format and cannot be considered as such. If you want to use the string for building SQL queries or for filtering DataView, use the approach described in the How to convert the CriteriaOperator to the corresponding filter string in order to use it for building SQL queries or for filtering the DataView Knowledge Base article.
