I need last 2 years year and month part as an integer with descending rank
in DBC.SYSEXECSQL
for example :
YEAR_MONTH_ID RELATIVE_MONTH
201304 1
201303 2
201302 3
201301 4
201212 5
201211 6
201210 7
201209 8
201208 9
201207 10
201206 11
201205 12
201204 13
201203 14
201202 15
201201 16
201112 17
201111 18
201110 19
201109 20
201108 21
201107 22
201106 23
201105 24
201104 25
I am using the following Stored procedure for the same
REPLACE PROCEDURE DB1.TEMP_SP(#IN_DATE DATE)
BEGIN
DECLARE TOD DATE;
DECLARE FOD DATE;
SET FOD = CAST((#IN_DATE-(365*2)-1) AS DATE);
SET TOD = CAST(#IN_DATE AS DATE);
CALL DBC.SYSEXECSQL('REPLACE VIEW DB1.TEMP_VIEW
AS
SELECT
CAST(CAST(CAST( CALENDAR_DATE AS FORMAT ''YYYYMM'') AS CHAR(6)) AS INTEGER) AS YEAR_MONTH_ID,
RANK() OVER( ORDER BY YEAR_MONTH_ID DESC ) AS "PERIOD_RANK"
FROM
SYS_CALENDAR.CALENDAR
WHERE CALENDAR_DATE BETWEEN :FOD AND :TOD
GROUP BY YEAR_MONTH_ID'
);
END;
Here i get an error :
3939 there is a mismatch between the number of parameters specified and the number of parameters required
When i replace the where clause in DBC.SYSEXECSQL
WHERE CALENDAR_DATE BETWEEN ''2011-04-01'' AND ''2013-04-01''
it works fine
Why is it so ?
