Query issue

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

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.
