SQL获取本周销售总数

select sum("NUMBER") as WEEK_NUMBER, COMPANY_CODE, PROJECT_CODE
    from D_VISIT
    WHERE "DATE" >= (TO_DATE('2014-03-29','yyyy-mm-dd') - (mod(TO_NUMBER(to_char(TO_DATE('2014-03-29','yyyy-mm-dd'),'D'))+7-2,7)))
AND "DATE" <= TO_DATE('2014-03-29','yyyy-mm-dd')
group by COMPANY_CODE, PROJECT_CODE
