How to show "*","on","as",">=,

Hi guys,

I have question about transferring some signal in CE function

For example

select a.*

from "Table1" as a

left outer join

"Table2" as c

on c.objid = a.orglv

AND c.BEGDA <= :input_parameter1

AND c.ENDDA >= :input_parameter1

         and c.OTYPE = 'O'

How can I show "select a.*"

                           "Table1 as a",

                            "on c.objid=a.orglv"

                            and ">=input_parameter"

                                   "= 'O'"

in CE function?
