In workbench we have a process, which will accept the PDF as Input and
converts to xml. I have one attribute which is coming as string but in
database thats stored as Varchar. But uisng that i have to compare >=
and < todetermine further logic by executing a SQL query or by
conditions. The SQL Query is failing as even if i try to convert to
number using experession its still not working.Any help would be greatly
appreciated.
