代碼如下:
declare @Q_ID uniqueidentifier
set @Q_ID = dbo.uf_GetParamValueByName(@Params,'@指標ID');
declare @QAExp_ID char(36) --指標屬性公式ID
set @QAExp_ID='3D2B8F3F-0B7E-46FD-9B33-050F846C2869'
declare @temp_qid table(QID char(36),ExpValue nvarchar(max)) --臨時表變量獲得指標根ID
declare @QIDtemp char(36),@express nvarchar(4000)
declare @k int=2 --層次
declare @pattern nvarchar(2)='ID' --指標公式拆分字段
declare @charidex int --指標對應的索引
if(@OPType = '根據指標ID查找公式所有子指標')
begin
create table #TempQuotaStruct --創建臨時表#TmpStruct
(
QID char(36), --創建一個ID用來存儲指標ID
PID char(36), --用來存儲該指標相關的iD
OrderValue int --層級關系
)
insert #TempQuotaStruct(QID,OrderValue)values(@Q_ID,1)
while EXISTS(select Q_ID from EOTS_QuotaAttributeValue where QA_ID=@QAExp_ID and Q_ID in (select QID from #TempQuotaStruct where OrderValue=@k-1) )
begin
insert into @temp_qid select Q_ID,QAV_Value from EOTS_QuotaAttributeValue whereQA_ID=@QAExp_IDand Q_ID in (select QID from #TempQuotaStruct whereOrderValue=@k-1)
WHILE EXISTS(select QID from @temp_qid)
begin
select top 1 @QIDtemp=QID, @express=ExpValue from @temp_qid
print @QIDtemp
set @express=rtrim(ltrim(@express))
set @charidex=charindex(@pattern,@express)
while @charidex>=1
begin
insert into #TempQuotaStruct(QID,PID,OrderValue)values(SUBSTRING(@express,@charidex+2,36),@QIDtemp,@k)
set @express=SUBSTRING(@express,@charidex+38,len(@express)-@charidex+37)
set @charidex=charindex(@pattern,@express)
end
delete from @temp_qid where QID = @QIDtemp
end
set @k=@k+1
end
select a.*,b.Q_Name, c.QAV_Value as Q_Formula from #TempQuotaStruct a,EOTS_Quota b,EOTS_QuotaAttributeValue c where a.QID=b.Q_ID and a.QID=c.Q_ID and c.QA_ID='3D2B8F3F-0B7E-46FD-9B33-050F846C2869'
此SQL是對標模塊的臨時表查詢，他能查出一個指標下面的多個子指標的公式，并分層級顯示 @指標ID=#*1*#;#*1*#08bea0aaf-0ed2-4c9b-8c20-8c5bd919db6f#*1*#
摘自EOTS 存儲過程up_eots_Get_QuotaStruct
臨時表循環的關鍵就是下面的語句, select top 1 from #Tep,用一個變量循環取值，然后刪除循環中的值
復制代碼代碼如下:
insert into #Tep select optname,value,major_version from MSreplication_options
while Exists(select a from #Tep)
begin
select top 1 @tempa =a,@tempc =c from #Tep
delete #Tep where a=@tempa
end
