Converting Access IIF to oracle

Question

Having issues converting IIf(VW_GE_ALL_YEARQRY.DEP="AG","AG","OT") AS DEPT, to Oracle

Select
VW_GE_ALL_YEARQRY.year,
VW_GE_ALL_YEARQRY.LOC,
VW_GE_ALL_YEARQRY.CAT,
VW_GE_ALL_YEARQRY.TY,
(case when VW_GE_ALL_YEARQRY.DEP = 'AG' then 'AG' else 'OT' end) as DEPT,
VW_GE_ALL_YEARQRY.SRCE,
Sum(VW_GE_ALL_YEARQRY.EXPEND * 0.001) As EXP
From
VW_GE_ALL_YEARQRY
GROUP BY VW_GE_ALL_YEARQRY.year, VW_GE_ALL_YEARQRY.LOC, VW_GE_ALL_YEARQRY.CAT, VW_GE_ALL_YEARQRY.TY, (case when VW_GE_ALL_YEARQRY.DEP = 'AG' then 'AG' else 'OT' end) as DEPT, VW_GE_ALL_YEARQRY.SRCE
HAVING (((Sum(VW_GE_ALL_YEARQRY.EXPEND * 0.001)))<>0);

The query tells me that i have an error, seems trivial at this point

Error at Command Line:11 Column:169
Error report:
SQL Error: ORA-00933: SQL command not properly ended
00933. 00000 -  "SQL command not properly ended"

If the only issue is the one in your text, then it is easy. Use case (which is ANSI standard):

(case when VW_GE_ALL_YEARQRY.DEP = 'AG' then 'AG' else 'OT' end) as DEPT

Here is a full version of your query:

Select v.year, v.LOC, v.CAT, v.TY,
       (case when VW_GE_ALL_YEARQRY.DEP = 'AG' then 'AG' else 'OT' end) as DEPT
       v.SRCE,
       Sum(v.EXPEND * 0.001) As EXP
From VW_GE_ALL_YEARQRY v
GROUP BY v.year, v.LOC, v.CAT, v.TY,
         (case when VW_GE_ALL_YEARQRY.DEP = 'AG' then 'AG' else 'OT' end), v.SRCE
HAVING Sum(v.EXPEND * 0.001) <> 0;

I have simplified it by using table aliases. And I removed the as DEPT from the group by clause. And, I replaced the double quotes strings with single quoted strings.
