CAN WE HAVE IF CONDITION IN QUERY GENERATOR

Question

Hi friends,
am, trying to make use of if condition to obtain a set of values in query generator.  Its possible to retrieve the required result set using query analyser but not in query generator.  am trying to execute the following query
if exists (select owor.u_reactor from owor,oitt where oitt.code=owor.itemcode and owor.u_reactor = 1 and owor.itemcode = '100-100')
begin
                select itt1.u_reactor1 from oitt,itt1 where itt1.father = oitt.code and itt1.father = '100-100'
end
else
if exists (select owor.u_reactor from owor,oitt where oitt.code=owor.itemcode and owor.u_reactor = 2 and owor.itemcode = '100-100')
begin
     select itt1.u_reac_23 from oitt,itt1 where itt1.father = oitt.code and itt1.father = '100-100'
end
else
if exists (select owor.u_reactor from owor,oitt where oitt.code=owor.itemcode and owor.u_reactor = 3 and owor.itemcode = '100-100')
begin
     select itt1.u_reactor4 from oitt,itt1 where itt1.father = oitt.code and itt1.father = '100-100'
end
if it is not possible to write such query in query generator  can someone help me with a workaround solution.
Thank u

Hi,
I dont think Nested IF Statements are allowed in PLD. The reason that u get the result in Query analyser and not in Query Generator is that SAP supports Transact SQL and many SQL Server 2000 functions are not supported.
However there is a work around in Print Layout Designer for using IF condition by having Linked Objects. Kindly see some tutorials regarding Linked fields available on SDN site and think of some other way of implementing this nested IF query.
