Hi All,
I have two data sets. Attached are them in xls format. Rainfall_data has rainfall value for each day for different years. Where as Cover_index has START_DATE and END_DATE for a particular phase. Now i want summation of rainfall for each year only for those dates that lies between START_DATE and END_DATE from Cover_index . I used the code as below:
PROC SQL;
CREATE TABLE TEST AS
SELECT YEAR(B.DATE),SUM(B.RAIN) FROM COVER_INDEX A, RAINFALL_DATA B
WHERE (DAY(B.DATE) BETWEEN DAY(A.START_DATE) AND DAY(A.END_DATE))
AND (MONTH(B.DATE) BETWEEN MONTH(A.START_DATE) AND MONTH(A.END_DATE))
GROUP BY YEAR(B.DATE);
QUIT;
But its not giving me correct output. Pleae suggest how can we do this.
There is one issue here . That is START_DATE and END_DATE has values 20Jun2010 and 09Jul2010. But i want summation of rainfall for dates that lies between 20jun and 09jul for all the years given in Rainfall_Data
Guys help me out.
Looks like you have an emergency ,
PROC SQL;
CREATE TABLE TEST AS
SELECT YEAR(B.DATE),SUM(B.RAIN) FROM COVER_INDEX A, RAINFALL_DATA B
WHERE B.DATE BETWEEN mdy(month(A.START_DATE),DAY(A.start_DATE),year(b.date))
AND mdy(MONTH(A.end_DATE),day(a.end_date),year(b.date))
GROUP BY YEAR(B.DATE);
QUIT;
It may have typos, but you get the idea.
