Below script provides a further example of the above. Suppose we want the name whose symbol string is currently 'employe' to also have the symbol string 'employee' (note the additional 'e' at end). Will the original db, schema and user-defined function still work? See below:

// Allow existing name whose symbol string is 'employe' // to have a second symbol string 'employee'. (create (and (select name instance *)

             (select * symbol 'employe')
        )
        symbol
        'employee'

// Verify getRoot function works with employe and employee. // Both of the following display eve !!! (msgbox (getRoot employe adam))
(msgbox (getRoot employee adam))

Note that in the above expressions, employe is translated by parser into:
(firstNode (select * name (firstNode (select * symbol (select 'e' 'm' 'p' 'l' 'o' 'y' 'e')))))

And employee is translated by parser into: (firstNode (select * name (firstNode (select * symbol (select 'e' 'm' 'p' 'l' 'o' 'y' 'e' 'e')))))

Both of the above queries find the same verb instance whose name has two similar symbol strings. Received on Sat Apr 01 2006 - 14:13:40 CST
