How do I decode a row of data using a date range as my parameter

Question

I am trying to do a decode against an Oracle server and return a fiscal year if date ranges fall in between what is listed below. I keep getting 'ORA-00907: missing right parenthesis' and I am sure it is something simple or maybe I am not using correct syntax for the date range but any help would be appreciated. Thanks!

SELECT ISSUE_DT,
MAX(DECODE(ISSUE_DT >= '01-JUL-11' AND ISSUE_DT <= '30-JUN-12','2012',ISSUE_DT >= '01-JUL-12' AND ISSUE_DT <= '30-JUN-13','2013',ISSUE_DT >= '01-JUL-13' AND ISSUE_DT <= '30-JUN-14','2014','NONE'))FISCAL_YEAR
FROM PS_GSU_AWD_INFO_VW

UPDATE

This is my current SQL statement that returns two columns, the year with quarter and total amount. I ultimately need the quarter and fiscal year in two separate places:

select CASE 
WHEN ISSUE_DT >= '01-JUL-11' AND ISSUE_DT <= '30-SEP-11' THEN 'FY12 Q1' 
WHEN ISSUE_DT >= '01-OCT-11' AND ISSUE_DT <= '31-DEC-11' THEN 'FY12 Q2'

Answer 1

I figured out a query that works. Not sure if this is best practices or not but here my is code:

SELECT DECODE(FISCAL_QUARTER,'FY12 Q1',2012,'FY12 Q2',2012,'FY12 Q3',2012,

Answer 2

You cannot use DECODE to test anything other than equality. You can, however, use the much more robust and much more standard CASE function

CASE WHEN issue_dt >= date '2011-07-01' AND issue_dt <= date '2012-06-30'
     THEN '2012'
     WHEN issue_dt >= date '2012-07-01' AND issue_dt <= date '2013-06-30'
     THEN '2013'
     WHEN issue_dt >= date '2013-07-01' AND issue_dt <= date '2014-06-30'
     THEN '2014'
     ELSE 'NONE'
 END

It probably makes sense, though, to do this via a calculation rather than hard-coding every year's range

to_char( issue_dt + interval '6' month, 'yyyy' )

Answer 3

A bit late, but you can try this:

SELECT 'FY'||to_char(add_months(t.issue_dt,6), 'YY')||' Q'||DECODE(FLOOR(EXTRACT(month from t.issue_dt)/4), 0, '3', 1, '4', 2, '1', 3, '2', 'E') 
FROM t
