CASE conversion from IIF

Question

I started off with SQL (access)

IIf(Len([CAT]) < 3, 
Left([CAT],1) & 0 & Right([CAT],1),
[CAT]) AS CAT1, 
[HD0] &

IIf([TABLE].[HD1]<>\"00\"         


        

Answer 1

MS Access syntax is entirely different to Oracle syntax. No square brackets, and different names for the SQL functions. http://docs.oracle.com/cd/E11882_01/server.112/e17118/functions.htm#SQLRF006

 Case
   When length(cat) < 3
   Then SubStr(cat,1,1) || '0' || SubStr(cat,-1,1)
   Else cat
 End cat1
