How can I do this three steps in the same SQL?

Question

My question is how I can do this in the same issue?
1. Today I do it in three steps. First I create a query, qryWC_ResultList.
2. The query qryWC_ResultList is used in this SQL. Results are saved in tblAppendWC_Quantity
3. Table tblWc updating of the data from tblAppendWC_Quantity
qryWC_ResultList
SELECT MATERIAL, Component From result_list
WHERE INFO = 'UTime'
AND SIGNUM = 'Test'
AND Not Component Is Null
GROUP BY MATERIAL, Component;
tblAppendWC_Quantity
Insert Into tblAppendWC_Quantity (Component, Qty, SIGNUM, Unit)
SELECT Rtrim(Case when qryWC_ResultList.Component Like '4%' Or qryWC_ResultList.Component Like'5%' Then Substr(qryWC_ResultList.Component,1,4) Else qryWC_ResultList.Component End) AS Component,
Sum(result_list.Qty) AS Qty, result_list.SIGNUM,
Case when result_list.INFO Is Null then 'M' Else result_list.INFO End AS Unit
FROM result_list, qryWC_ResultList
WHERE  result_list.Component = qryWC_ResultList.Material
And result_list.Qty > 0
AND result_list.SIGNUM = 'Test'
And result_list.INFO = 'UTime'
GROUP BY Rtrim(Case when qryWC_ResultList.Component Like '4%' Or qryWC_ResultList.Component Like'5%' Then Substr(qryWC_ResultList.Component,1,4) Else qryWC_ResultList.Component End) ,
Case when result_list.INFO Is Null Then 'M' Else result_list.INFO End, result_list.SIGNUM ;
Update table tblWC
UPDATE tblWC set
tblWC.METERS = tblAppendWc_Quantity.Qty,
tblWC.UNIT = tblAppendWc_Quantity.Unit
where tblWC.SIGNUM = tblAppendWC_Quantity.SIGNUM
AND tblWC.COMPONENT = tblAppendWC_Quantity.COMPONENT Edited by: user570142 on 2009-sep-25 06:17

Den Kenny,
Your example is exactly what I want. All temporary queries (views) should creates in the SQL.
But I can't get it work. What is wrong with this?
with qryWC_ResultList  as (SELECT distinct MATERIAL, Component From result_list
              WHERE INFO = 'UTime'
                AND SIGNUM = 'Test'
                AND Not Component Is Null)
,tblAppendWC_Quantity as  (SELECT Rtrim(Case when qryWC_ResultList .Component Like '4%' Or qryWC_ResultList.Component Like'5%'
                    Then Substr(qryWC_ResultList.Component,1,4)
                    Else qryWC_ResultList.Component
               End) AS Component
        ,Sum(result_list.Qty) AS Qty
        ,result_list.SIGNUM
        ,Case when result_list.INFO Is Null
              then 'M'
              Else result_list.INFO
         End AS Unit
    FROM result_list, qryWC_ResultList
   WHERE  result_list.Component = qryWC_ResultList.Material
     And result_list.Qty > 0
     AND result_list.SIGNUM = 'Test'
     And result_list.INFO = 'UTime'
   GROUP BY Rtrim(Case when qryWC_ResultList.Component Like '4%' Or qryWC_ResultList.Component Like'5%'
                       Then Substr(qryWC_ResultList.Component,1,4)
                       Else qryWC_ResultList.Component
                  End)
            ,Case when result_list.INFO Is Null
                 Then 'M'
                 Else result_list.INFO
            End
           ,result_list.SIGNUM)
Select  tblAppendWc_Quantity.Qty, tblAppendWc_Quantity.Unit, tblAppendWC_Quantity.SIGNUM
from tblAppendWC_Quantity
update tblWC set tblWC.METERS = tblAppendWc_Quantity.Qty
                ,tblWC.UNIT = tblAppendWc_Quantity.Unit
where tblWC.SIGNUM = tblAppendWC_Quantity.SIGNUM
   AND tblWC.COMPONENT = tblAppendWC_Quantity.COMPONENT;
