Question

我的查询需要帮助。我试图从1月到2月生成一份清单。但是在我的查询中我不确定哪个部分我做错了或错误它只抓住了二月份的记录。好心提醒。谢谢你

    set @FirstDateOfNextMth = CONVERT(varchar,dateadd(d,-(day(dateadd(m,1,getdate()-2))),dateadd(m,1,getdate())),112)
set @LastDateOfNextMth = CONVERT(varchar,dateadd(d,-(day(dateadd(m,2,getdate()))),DATEADD(m,2,getdate())),112)


--------------------------------------------------

INSERT INTO [dbo].[ProcessLog] ([LogTime] ,[LogDescription] ,[LogRemark])
VALUES (GETDATE(), 'Import Client Info', '')

--------------------------------------------------

SET @sSQL = 'SELECT DISTINCT CHDR.CHDRNUM, ZTRN.CCDATE, CHDR.CRDATE, CLNT.CLNTNUM, CLNT.SURNAME, CLNT.GIVNAME,
            CLNT.SECUITYNO, ZCLN.EMAIL from (((MPIDTA.ZTRNPF AS ZTRN 
            LEFT JOIN MPIDTA.CHDRPF AS CHDR ON ZTRN.RLDGACCT = CHDR.CHDRNUM AND ZTRN.EFFDATE = CHDR.CURRFROM)
            LEFT JOIN MPIDTA.CLNTPF AS CLNT ON CHDR.COWNNUM = CLNT.CLNTNUM)
            LEFT JOIN MPIDTA.ZCLNPF AS ZCLN ON CLNT.CLNTNUM = ZCLN.CLNTNUM)
            where (ZTRN.BATCPFX = ''BA'' AND ZTRN.BATCCOY = ''1''
            AND ZTRN.CNTTYPE = ''PTB'' AND ZTRN.TRANDATE >= ''20140101'' 
            AND (ZTRN.EXPIRY_DATE BETWEEN ' + @FirstDateOfNextMth + ' AND ' + @LastDateOfNextMth + '))
            AND (CHDR.MPLNUM = '''' AND CHDR.CHDRPFX = ''CH''
            AND CHDR.CHDRCOY = ''1'' AND CHDR.VALIDFLAG = ''1'')'

SET @sExe = 'Insert into dbo.TPA_Client_Info Select * FROM OPENQUERY(AS400, ''' + REPLACE(@sSQL, '''', '''''') + ''')'

exec (@sExe)

问题出在@FirstDateOfNextMth。

set @FirstDateOfNextMth = CONVERT(varchar,dateadd(d,-(day(dateadd(m,1,getdate()-2))),
                          dateadd(m,1,getdate())),112)

结果为20150202

由于@FirstDateOfNextMth为20150202，因此条件ZTRN.EXPIRY_DATE仅在feb个月之间进行过滤。尝试改变这样。

 set @FirstDateOfNextMth = DATEADD(yy, DATEDIFF(yy,0,getdate()), 0)

获取1月日期月记录
