Question

我正在做水晶报告，用户要求做的事情就像只显示已经检查过的数据

日期自[日历]

日期到[日历]

在[Checkbox]之前显示数据

在[Checkbox]

之后显示数据

显示不同的[Checkbox]

@dateTo datetime
@dateFrom datetime
@showdatab4 nvarchar // or what?
@showdataAf nvarchar  //or what?
@showDiff   nvarchar // or what?

Select dataBefore, dataAfter, differential, date_from ,date_to 
from tableA
where date_from >= @datefrom and date_to <DATEADD(d,1,@dateTo)

我打算做的事情就像是

IF showdatab4 = check

Select dataBeforedate_from ,date_to

from tableA

where date_from >= @datefrom and date_to <DATEADD(d,1,@dateTo)

else if showdatab4 = checked and showdataAf = checked
Select dataBefore, dataAfter,  date_from ,date_to from tableA
where date_from >= @datefrom and date_to <DATEADD(d,1,@dateTo)

这不够智能，是否有更好的方法来实现我的目标？

好的，然后您可以根据条件创建动态SQL查询。假设像这样。这只是你的想法。

--EXEC SP_LoanCustomerInterest 'DETAIL','','019','9/1/2011','9/1/2011','L1'
ALTER PROC SP_LoanCustomerInterest(@DS VARCHAR(20),@AC_NO VARCHAR(50),@BR_CODE VARCHAR(10),@Edate1 VARCHAR(20),@EDATE2 VARCHAR(20),@AC_GROUP_CODE VARCHAR(MAX)='')
AS 
BEGIN
--CREATED BY : NP SUBEDI FOR WEB BASED REPORT - JUNE 12 2013
SET NOCOUNT ON

DECLARE @SQL VARCHAR(MAX)=''
CREATE TABLE #TEMP(FIELD1 VARCHAR(50))
DECLARE @I INT=1
DECLARE @POS INT=1
SET NOCOUNT ON
WHILE @POS<LEN(@AC_GROUP_CODE)
    BEGIN
        INSERT INTO #TEMP(FIELD1)VALUES(SUBSTRING(@AC_GROUP_CODE,@I,2))
        SET @POS=@POS+3
        SET @I=@POS
    END

If (@DS = 'DETAIL' )
    BEGIN
       SET @SQL = 'SELECT DISTINCT DBO.GETACNAME(LAM.AC_NO,'''+@BR_CODE+''') AS AC_NAME,AG.AC_GROUP_NAME,LT.AC_NO,LT.AC_GROUP_CODE,LT.TRAN_DATE,DBO.ENGTONEP(LT.TRAN_DATE) AS TRAN_NDATE,

        If @AC_NO<> ''

    END

If (@DS <> 'DETAIL')

EXEC sp_sqlexec @SQL

希望您了解上述查询。以上查询的目的是实现动态条件。 EXEC sp_sqlexec @SQL 这就是你所需要的。您可以在@SQL Variable上传递任何SQL查询。因此，根据您的条件创建@SQL并传递它。

隐藏和显示选定的列数据
