此SP由sp_send_dbmail调用，该日志在作业上每天执行。如果此报告中没有任何要显示的记录，我不希望发送带有＆＃39; 0行的部分受影响＆＃39;我仍然想报告有记录的部分。
这是我的sp它实际上有15个单独的select语句，但是为了节省空间我只显示2

我在这里使用sp_send_dbmail
调用它EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'DBMail,
@recipients = 'me@me.com',
@subject = 'FLAT_Daily',
@query = N'EXEC PTW.dbo.SP_FLAT_Daily',
@query_attachment_filename = 'FLAT_Daily.txt'
以下是我的结果

有些日子我都有记录，但是有时候只有一部分有记录。如何只发送有记录的内容？
还要将结果集分组如下。仅显示所有部门associateName的相同codes个人在指定时间内工作。

开始IF EXISTS中的每个选择。例如：
IF EXISTS (
SELECT * FROM PTW.dbo.TimeLog
WHERE EventDate BETWEEN @StartReportDate2 AND @EndReportDate2
AND DeptCode = 'FS' AND OpCode = 'FD'
)
SELECT StatDate = TimeLog.EventDate
,[ID#] = a.ID
,Codes = (a.DeptCode + '-' + a.OpCode)
,TotalTime = convert(time(0),dateadd(second,sum(datediff(second,StartTime,FinishTime)),0))
,Units = SUM(Units)
,UPH = cast(isnull(sum(Units) / nullif(sum(datediff(minute,StartTime,FinishTime))*1.0,0),0.0)*60 as decimal(10,0))
,AssociateName = (b.FirstName + ' ' + b.LastName)
FROM PTW.dbo.TimeLog a LEFT JOIN PTW.dbo.AssociateInfo b
ON a.ID = b.ID
WHERE EventDate BETWEEN @StartReportDate2 AND @EndReportDate2 AND DeptCode = 'FS' AND OpCode = 'FD'
GROUP BY a.EventDate, a.ID, a.DeptCode, a.OpCode, b.FirstName, b.LastName
ORDER BY UPH DESC
IF EXISTS (SELECT * FROM query2)
SELECT column from query2
如果存在记录，则执行下一行

解决此问题的一种方法是将可重用查询移动到自己的过程中，并从日常报告过程中执行该过程。
这仍然只是使用if exists()来确定是否按照Nick McDermaid的建议返回结果集，但它简化了代码。
create procedure dbo.SP_FLAT_Daily_Query (
@StartReportDate datetime
, @EndReportDate datetime
, @DeptCode char(2)
, @OpCode char(2)
, @Goal decimal(10,2)
) as
begin;
--set nocount on; /* removes (N row(s) affected message)
if exists (
select 1
from TimeLog t
where t.EventDate >= @StartReportDate
and t.EventDate <= @EndReportDate
and t.DeptCode = @DeptCode
and t.OpCode = @OpCode
)
begin;
select
StatDate = convert(char(10),t.EventDate,120)
, t.ID
, Codes = (t.DeptCode + '-' + t.OpCode)
, TotalTime = right('0' + convert(varchar(9),(sum(datediff(second,StartTime,FinishTime)) / 3600 )),2) + ':'
+ right('0' + convert(varchar(2),(sum(datediff(second,StartTime,FinishTime)) / 60) % 60 ),2) + ':'
+ right('0' + convert(varchar(2),(sum(datediff(second,StartTime,FinishTime)) % 60 )),2)
, Units = sum(Units)
, UPH = cast(isnull(sum(Units) / nullif(sum(datediff(minute,StartTime,FinishTime))*1.0,0),0.0)*60 as decimal(10,0))
, [Goal%] = (convert(varchar(30),cast((isnull(sum(Units) / nullif(sum(datediff(minute,StartTime,FinishTime))*1.0,0),0.0)*60)/nullif(@Goal,0)*100 as decimal(10,0))) + '%')
, AssociateName = isnull(ai.FirstName + ' ','') + isnull(ai.LastName,'')
from TimeLog t
left join AssociateInfo ai
on t.Id = ai.Id
where t.EventDate >= @StartReportDate
and t.EventDate <= @EndReportDate
and t.DeptCode = @DeptCode
and t.OpCode = @OpCode
group by t.EventDate, t.id, t.DeptCode, t.OpCode, ai.FirstName, ai.LastName
order by t.id desc;
end;
end;
go
然后在您的日常过程中，重用您的变量并使用所需的每组变量执行查询过程。
以下示例中的代码是详细的，并为相同的变量重复相同的值赋值，但我这样做是为了让您可以轻松调整实际代码。
create procedure dbo.SP_Flat_Daily as
begin;
--set nocount on; /* removes (N row(s) affected message)
declare
@Now datetime
, @StartReportDate datetime
, @EndReportDate datetime
, @DeptCode char(2)
, @OpCode char(2)
, @Goal decimal(10,2);
------------------------------------------THIS IS FOR DEPARTMENT CODE [FS - FT]
select
@Now = getdate()
, @StartReportDate = dateadd(day, datediff(day, 0, getdate()), -1)
, @EndReportDate = dateadd(day, datediff(day, 0, getdate()), -1)
, @DeptCode = 'fs'
, @OpCode = 'ft'
, @Goal = 295.0;
exec dbo.SP_FLAT_Daily_Query @StartReportDate, @EndReportDate, @DeptCode, @OpCode, @Goal;
------------------------------------------THIS IS FOR DEPARTMENT CODE [NA - NA]
select
@Now = getdate()

, @DeptCode = 'na'
, @OpCode = 'na'
, @Goal = 0;
exec dbo.SP_FLAT_Daily_Query @StartReportDate, @EndReportDate, @DeptCode, @OpCode, @Goal;
------------------------------------------THIS IS FOR DEPARTMENT CODE [FS - FD]
select
@Now = getdate()
, @StartReportDate = dateadd(day, datediff(day, 0, getdate()), -1)

, @DeptCode = 'fs'
, @OpCode = 'fd'
, @Goal = 1552.0;
exec dbo.SP_FLAT_Daily_Query @StartReportDate, @EndReportDate, @DeptCode, @OpCode, @Goal;
end;
go
