插入到表格中逗號分隔列表中的變量值

Question

declare @List varchar(25) = '2,3,4' 
declare @Delinquencies table (id int); 
insert into @Delinquencies(id) values('2'),('3'),('4'); --Line in question 

@List正在填充從SSRS報告中填充的字符串，併爲其選擇了選項。現在我的存儲過程運行的方式，我需要能夠插入到我的表變量基於什麼varchar列表正在通過。我如何插入到具有動態varchar列表的表變量？此處列出的內容與我所能達到的測試格式差不多。

我使用SQL Server 2008的

例

@List = '1' 
insert into @Delinquencies(id) values('1') 

而且任何組合高達

@List = '1,2,3,4' 
insert into @Delinquencies(id) values('1'),('2'),('3'),('4') 

Answer 1

使用拆分string functions from here之一..

declare @List varchar(25) = '2,3,4'; 
declare @Delinquencies table (id int); 

;with cte 
as 
(select * from 
[dbo].[SplitStrings_Numbers](@list,',') 
) 

insert into @Delinquencies(id) 
select * from cte 

Answer 2

你需要t o創建一個dbo.StringSplit函數

採用兩個參數（字符串，分隔符）

CREATE function [dbo].[StringSplit](
@String varchar (max), 
@Delimiter nvarchar (10) 
) 
returns @ValueTable table ([Value] varchar(max)) 
begin 
declare @NextString varchar(max) 
declare @Pos int 
declare @NextPos int 
declare @CommaCheck nvarchar(1) 

--Initialize 
set @NextString = '' 
set @CommaCheck = right(@String,1) 

--Check for trailing Comma, if not exists, INSERT 
--if (@CommaCheck <> @Delimiter) 
set @String = @String + @Delimiter 

--Get position of first Comma 
set @Pos = charindex(@Delimiter,@String) 
set @NextPos = 1 

--Loop while there is still a comma in the String of levels 
while (@pos <> 0) 
begin 
    set @NextString = substring(@String,1,@Pos - 1) 

    insert into @ValueTable ([Value]) Values (@NextString) 

    set @String = substring(@String,@pos +1,len(@String)) 

    set @NextPos = @Pos 
    set @pos = charindex(@Delimiter,@String) 
end 

return 
end 

，然後可以用它像下面

declare @List varchar(25) = '2,3,4' 
SELECT value from dbo.StringSplit(@List,',') 

Answer 3

這裏是一個解析器它返回序列以及。

例如：

Select * from [dbo].[udf-Str-Parse]('126,256,512',',') 

返回

Key_PS Key_Value 
1  126 
2  256 
3  512 

的UDF

CREATE FUNCTION [dbo].[udf-Str-Parse] (@String varchar(max),@Delimeter varchar(10)) 
--Usage: Select * from [dbo].[udf-Str-Parse]('Dog,Cat,House,Car',',') 
--  Select * from [dbo].[udf-Str-Parse]('John Cappelletti was here',' ') 

Returns @ReturnTable Table (Key_PS int IDENTITY(1,1), Key_Value varchar(max)) 
As 
Begin 
    Declare @XML xml;Set @XML = Cast('<x>' + Replace(@String,@Delimeter,'</x><x>')+'</x>' as XML) 
    Insert Into @ReturnTable Select Key_Value = ltrim(rtrim(String.value('.', 'varchar(max)'))) FROM @XML.nodes('x') as T(String) 
    Return 
End
