多条款条件

Question

对于多重where子句条件，我具有以下语法。 sql不接受语法。 有人可以为我指出正确的方向，说明如何使多个条件正常工作。

   Declare @PopulationDate Datetime = '02-01-16';

DECLARE @Month1 AS integer;
DECLARE @Year1 as integer;
DECLARE @Month2 as integer;
Declare @Year2 as integer;
DECLARE @Month3 as integer;
Declare @Year3 as integer;
DECLARE @Month4 as integer;
Declare @Year4 as integer;
DECLARE @lastyear as integer;
Declare @CurrentMonth as DAte;
Set @CurrentMonth =  CONVERT(VARCHAR(25),DATEADD(dd,-(DAY(@PopulationDate)-1),@PopulationDate),101);


       set @Month1 = Month(DATEADD(MONTH, -4, @PopulationDate));
       set @Year1  = Year(DATEADD(Month, -4, @PopulationDate));
       set @Month2 = Month(DATEADD(MONTH, -3, @PopulationDate));
       set @Year2  = Year(DATEADD(MONTH, -3, @PopulationDate));
       set @Month3 = Month(DATEADD(MONTH, -2, @PopulationDate));
       set @Year3  = Year(DATEADD(MONTH, -2, @PopulationDate));
       set @Month4 = Month(DATEADD(MONTH, -1, @PopulationDate));
       set @Year4  = Year(DATEADD(MONTH, -1, @PopulationDate));

Declare @StartDate as Date 
= DATEADD(MONTH, -4, @PopulationDate);
 Declare @newdate as Date;--- pulls Start Date for probationer if in range of months being looked into. 
SET @newdate = CONVERT(VARCHAR(25),DATEADD(dd,-(DAY(@StartDate)-1),@StartDate),101);---- sets date

Answer 1

如果您的目标是获取过去90天的PAYMENT_YEAR（实际上包含日期时间，而不仅仅是一年），则无需比较过去3个月的月份和年份。 您可以使用DATEADD（） 。

这是一个简单的SQL Fiddle示例 。

对于您的特定查询，您的WHERE条件应该类似于：

WHERE pd.PROB_DATE_OFF > @PopulationDate
  AND pd.PROB_DATE_ON < @PopulationDate
  AND y.PAYMENT_YEAR >= DATEADD(DAY,-90,GETDATE())

这将返回满足所有3个条件的记录。 如果您需要满足前两个条件或在过去30天内的记录，请使用：

WHERE (pd.PROB_DATE_OFF > @PopulationDate
  AND pd.PROB_DATE_ON < @PopulationDate)
  OR y.PAYMENT_YEAR >= DATEADD(DAY,-90,GETDATE())

Answer 2

where pd.PROB_DATE_OFF > @PopulationDate
  and pd.PROB_DATE_ON < @PopulationDate
    --allows months and years to be pulled for payment data (Dominqiue A. Anderson January 2016) 
    --- second bracket makes statement true
    and((pg.PAYMENT_GRP_INDEX = @Month1 
    and py.PAYMENT_YEAR = @Year1)
    or (pg.PAYMENT_GRP_INDEX = @Month2
    and py.PAYMENT_YEAR = @Year2) 
    or (pg.PAYMENT_GRP_INDEX = @Month3
    and py.PAYMENT_YEAR = @Year3)
    or (pg.PAYMENT_GRP_INDEX = @Month4
    and py.PAYMENT_YEAR = @Year4))  --- second bracket makes statement true   
 )

--  order by pd.PIN_NBR, pd.PIN_SUF, pg.PAYMENT_GRP_INDEX
