我一直在编写这个存储过程，而且我对Stored Procedures不熟悉。我一直试图将插入放入循环中，但逻辑不对。
以下存储过程基本上只将最后一行插入表中。 但是，当我打印出临时表时，它会正确显示所有数据，但不知何故插入/更新无法正常工作
以下是存储过程的脚本。谁能告诉我，我在这里想念的是什么？

我不认为你那么遥远。我的理解是你想在tTemplate_Calculation中每个参数有一行，所以我会改变表的定义 因此，paramid是唯一的，但不是身份类型。
CREATE TABLE [dbo].[tTemplate_Calculation](
[id] [int] unique, --IDENTITY(1,1) NOT NULL,
[tTemplate_id] [int] NULL,
[formula] [nvarchar](10) NULL,
[property] [nvarchar](50) NULL,
[samplesRequired] [bit] NULL,
[tUnitOfMeasures_id] [int] NULL,
[employeeNo] [nvarchar](50) NULL,
[dateTimeStamps] [datetime] NULL )
，修改sp以在表变量中包含一个标识列，当你进入更新/插入阶段时，使用@i和@j变量创建一个循环，使用offset和fetch将数据从表变量传递回到声明的变量
alter PROCEDURE [dbo].[spAddIntoTemplateCalculationsTable]
( -- Add the parameters for the stored procedure here
@templateID nvarchar(max),@parameterList nvarchar(max),@EmployeeNo nvarchar(16))
AS
BEGIN
Declare @ErrorNo integer = '',
@ErrorMessage nvarchar(max) = '',
@SPName nvarchar(max) = '',
@i int ,
@j int
DECLARE @paramID nvarchar(MAX),@formula nvarchar(MAX), @property nvarchar(MAX),@samplesRequired nvarchar(MAX),@tUnitOfMeasures_id int,
@Pos int,@strSampleData nvarchar(MAX),@IntCounter int,@test int
DECLARE @tmpParameterParam table (id int identity , paramID nvarchar(MAX), formula nvarchar(MAX), property nvarchar(MAX), samplesRequired nvarchar(MAX),tUnitOfMeasures_id int)
set @i = 0
set @j = 0
SET @parameterList = LTRIM(RTRIM (@parameterList))+ ','
SET @Pos = CHARINDEX (',', @parameterList,1)
--SET @IntCounter = 1
IF REPLACE(@parameterList, ',' , '') <> ''
begin
WHILE @Pos > 0
BEGIN
SET @strSampleData = LTRIM(RTRIM(LEFT(@parameterList, @Pos -1)))
IF @strSampleData <> ''
BEGIN
set @paramID = substring(@strSampleData,0, CHARINDEX(':',@strSampleData,0))
--Remove the substring and move the string to the next token(column)
set @strSampleData = substring(@strSampleData, LEN(@paramID)+2, LEN(@strSampleData))
set @formula = substring(@strSampleData,0, CHARINDEX(':',@strSampleData,0))
--Remove the substring and move the string to the next token(column)
set @strSampleData = substring(@strSampleData, LEN(@formula)+2, LEN(@strSampleData))
--update tSpecScaleValidation set LastTriggeredTime=getdate() where id= @tSpecScaleValidation_id
set @property = substring(@strSampleData,0, CHARINDEX(':',@strSampleData,0))
set @strSampleData = substring(@strSampleData, LEN(@property)+2, LEN(@strSampleData))
set @samplesRequired = substring(@strSampleData,0, CHARINDEX(':',@strSampleData,0))
set @strSampleData = substring(@strSampleData, LEN(@samplesRequired)+4, LEN(@strSampleData))
set @tUnitOfMeasures_id = substring(@strSampleData,0, CHARINDEX(':',@strSampleData,0))
--to get the last token from the string(column)
set @tUnitOfMeasures_id = substring(@strSampleData, LEN(@tUnitOfMeasures_id)+1, LEN(@strSampleData))
insert into @tmpParameterParam
--select @IntCounter,@strSampleData
select @paramID,@formula,@property,@samplesRequired,@tUnitOfMeasures_id
END
SET @parameterList = RIGHT(@parameterList, LEN (@parameterList) - @Pos)
set @Pos = CHARINDEX(',', @parameterList,1)
SET @IntCounter = @IntCounter + 1
set @i = @i + 1
END
END
select @i as intcounter
begin transaction t1
begin try
declare @setno int
while @j < @i
begin
select @paramID = t.paramID ,
@formula = t.formula,
@property = t.property,
@samplesRequired = t.samplesRequired,
@tUnitOfMeasures_id = t.tUnitOfMeasures_id
from @tmpParameterParam t
order by t.id offset @i rows fetch next 1 rows only
if EXISTS (SELECT * FROM tTemplate_Calculation where id = @paramid)
begin
select 'updating' , @i, @j
update tTemplate_Calculation
set formula= @formula,
property = @property ,
samplesRequired=@samplesRequired,
tUnitOfMeasures_id=@tUnitOfMeasures_id
end
else
begin
select 'inserting' , @i, @j
insert into tTemplate_Calculation
( [id],
[tTemplate_id] ,
[formula] ,
[property],
[samplesRequired],
[tUnitOfMeasures_id] ,
[employeeNo] ,
[dateTimeStamps])
select @paramid, @templateID,@formula,@property,@samplesRequired,@tUnitOfMeasures_id,@EmployeeNo,getdate()
end
set @j =@j + 1
end
commit transaction t1
end try
Begin Catch
Select
@ErrorMessage = ERROR_MESSAGE(),
@SPName = ERROR_PROCEDURE(),
@ErrorMessage = ERROR_MESSAGE();
rollback transaction t1
select @ErrorMessage
End Catch
END
当sp被称为
时set nocount on
truncate table tTemplate_Calculation
exec [dbo].[spAddIntoTemplateCalculationsTable] @templateID=1,@parameterList='0:C:Test:0:0,0:B:TEST2:1:0,0:A-b/c*a::0:0', @EmployeeNo = 'test'
select * from tTemplate_Calculation
这是结果
intcounter

inserting 3 0

updating 3 1
-------- ----------- -----------
updating 3 2
id tTemplate_id formula property samplesRequired tUnitOfMeasures_id employeeNo dateTimeStamps
