    FilterValues Function

      FilterValues Function

      Post

      OK I've been using the FilterValues Function as 

      Field E = FilterValues (Field A; ValueListItems ( Get ( FileName ) ; "List Field D") )

      And this worked great up untill I was no longer able to keep Field D = List(List(Test 2::Field B);List(Test 2::Field C)) -That made up the Value List "List Field D"- As an indexed field.  

      Now I figured I would just do this:

      FilterValues ( Field A; Field D) but that returns all empty record so I tried FilterValues ( Field A; Field B) and FilterValues ( Field A; Field C) and it was the same result, just a list of empty cells when there are clear matches beween the fields. 

      Does anyone know how to get this to work.

          Please explain what results you want for this. What list of values do you want to produce in order to compare the value of field A to it to deterimine if that value is in the list?

          Just guessing here, but if you want the value of Field A returned if that value is in Field B of any record in the table or in Field C of any record in the table, you could do this:

          Define a value list of all values in Field B. Define a value list of all values in Field C.

          Use this expression:

          Filtervalues ( List ( ValueListItems ( get ( FileName ) ; "RieldBValueList" ) ; ValueListItems ( Get ( FileName ) ; "FieldCValueList" ) ) ; Field A )

            ValueListItems is what I was using before but in the main database that i am creating what represents Field B and Field C are calculation fields that can not be indexed and When I try to make them into a value list, Filemaker tells me that it will not work. So, using Value List is not an option.

            So I want to know is there a way to make the expression 

             

            FilterValue (Field A; Field B) and FilterValue (Field A; Field C) work, or simply use the list Field C not as a value list for FilterValue (Field A; Field C) (Note the first image for Field C is wrong as a list it only shows 3's ) Because when I try these calculations all it returns is empty cells.

            However, I do know of an alternative as I can reverse the formula and make Field A into the list as it is unchanging and can be indexed but I believe that that may make things even more complex for my table. So if there is another way please let me know.

              I help a lot of people at the same time so while I sort of remember your earlier posts it leaves me with an imperfect understanding of what you have set up ith Fields B and C. Without knowing how the values in B and C are derived, I can't really suggest anything.

                Hmmm, on second thought.

                If it is a list of all values in the table for these two fields, you could define a new calculationf field, BC as List ( B ; C ).

                Then a self join:

                Table::anyfield X Table 2::anyfield

                Where table and table 2 are occurrences of the same table with X specified as the cartesian join operator.

                Then you can use List ( Table 2::BC ) to produce a list of all values in B and C in a single list for use with filtervalues.

                  That works great, and I dont have to index the list. Thanks
