    mapping load

    Praveena Velagapudi

      I have below mapping load table


      ID ,Text

      002 ,text1

      2 ,text2


      when applymap is applied, it default takes to 2 for even 002. How can I fix it to exact?

          May be load ID field in the mapping table using Text() function:




          LOAD Text(ID) as ID,

            The reason is that a Mapping Table acts like a symbol table with dual values. Identical numerical values cannot have different text values, just like dual values.

                So it won't work even if force Text() function to it? Have not tested what I proposed, but I wonder if you already have tested this or know this for fact.

                    Yes, it works if you observe the rule that only text values are stored, and that QlikView should be blocked from interpreting and passing dual values with a numerical component to search for.


                    Anyway it shoyuld be easy to figure out what works and what doesn't. I used this code (copied from your post)


                    LOAD Text(ID) as ID, Text INLINE [
                    ID, Text
                    2, Text1
                    02, Text2
                    002, Text3
                    0002, Text4
                    LET vTest1 = applymap('MT', 2, 'NotFound');
                    LET vTest2 = applymap('MT', '02', 'NotFound');
                    LET vTest3 = applymap('MT', text('002'), 'NotFound');


                    to get this result
