我需要能够在SharePoint数据库中查询调查结果。我遇到问题的数据类型是“评级量表”值。因此，每个表格列中的数据代表了一整组子问题及其答案。
以下是一栏中的例子：
1。我们的功能定义了可用性如何衡量生产中的硬件/软件;＃3＃2。我们的功能存在可用性阈值水平（例如，SLA）;＃3＃3。当存在阈值违规时，我们的函数遵循定义的过程;＃4＃4。我们的功能收集并维护可用性数据;＃4＃5。比较分析有助于识别可用性数据的趋势;＃4＃6。运营级别协议（OLA）指导我们与其他内部团队的互动;＃4＃
问题以分号结尾，他们的答案在两个＃符号内。所以第一个问题的答案是3。
当我导出调查结果时，它将每个问题格式化为列标题，并将答案格式化为下面单元格中的值，这对于获得每个问题的平均值是理想的，并且希望能够复制该问题来自SQL查询。
但如果我能将查询结果分成两列（问题，答案）......我会对此感到非常兴奋。
感谢任何帮助。
非常感谢

您必须设置分割功能，但是一旦拥有它，请尝试使用此无光标解决方案：
I prefer the number table approach to split a string in TSQL
要使此方法起作用，您需要执行以下一次性表设置：
SELECT TOP 10000 IDENTITY(int,1,1) AS Number
INTO Numbers
FROM sys.objects s1
CROSS JOIN sys.objects s2
ALTER TABLE Numbers ADD CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number)
设置Numbers表后，创建此split函数，该函数将返回空字符串和行号：
CREATE FUNCTION [dbo].[FN_ListToTableRows]
(
@SplitOn char(1) --REQUIRED, the character to split the @List string on
,@List varchar(8000)--REQUIRED, the list to split apart
)
RETURNS TABLE
AS
RETURN
(
----------------
--SINGLE QUERY-- --this WILL return empty rows
----------------
SELECT
ROW_NUMBER() OVER(ORDER BY number) AS RowNumber
,LTRIM(RTRIM(SUBSTRING(ListValue, number+1, CHARINDEX(@SplitOn, ListValue, number+1)-number - 1))) AS ListValue
FROM (
SELECT @SplitOn + @List + @SplitOn AS ListValue
) AS InnerQuery
INNER JOIN Numbers n ON n.Number < LEN(InnerQuery.ListValue)
WHERE SUBSTRING(ListValue, number, 1) = @SplitOn
);
GO
您现在可以轻松地将CSV字符串拆分为表格并加入其中，注意此拆分函数返回空字符串和行号：
select * from dbo.FN_ListToTableRows(',','1,2,3,,,4,5,6777,,,')
输出：
RowNumber ListValue
-------------------- ------------
1 1
2 2
3 3
4
5
6 4
7 5
8 6777
9
10
11
(11 row(s) affected)
您现在可以使用CROSS APPLY来分割表格中的每一行，如：
DECLARE @YourTable table (RowID int, RowValue varchar(8000))
INSERT INTO @YourTable VALUES (1,'1. Our function has defined how Availability is measured the hardware/software in Production;#3#2. Availability threshold levels exist for our function (e.g., SLA''s);#3#3. Our function follows a defined process when there are threshold breaches;#4#4. Our function collects and maintains Availability data;#4#5. Comparative analysis helps identify trending with the Availability data;#4#6. Operating Level Agreements (OLA''s) guide our interaction with other internal teams;#4#')
INSERT INTO @YourTable VALUES (2,'1. one;#1#2. two;#2#3. three;#3#')
INSERT INTO @YourTable VALUES (3,'1. aaa;#1#2. bbb;#2#3. ccc;#3#')
;WITH AllRows As
(
SELECT
o.RowID,st.RowNumber,st.ListValue AS RowValue
FROM @YourTable o
CROSS APPLY dbo.FN_ListToTableRows('#',LEFT(o.RowValue,LEN(o.RowValue)-1)) AS st
)
SELECT
a.RowID,a.RowValue AS Question, b.RowValue AS Answer
FROM AllRows a
LEFT OUTER JOIN AllRows b ON a.RowID=b.RowID AND a.RowNumber+1=b.RowNumber
WHERE a.RowNumber % 2 = 1
输出：
RowID Question Answer
----------- ----------------------------------------------------------------------------------------------- -------
1 1. Our function has defined how Availability is measured the hardware/software in Production; 3
1 2. Availability threshold levels exist for our function (e.g., SLA's); 3
1 3. Our function follows a defined process when there are threshold breaches; 4
1 4. Our function collects and maintains Availability data; 4
1 5. Comparative analysis helps identify trending with the Availability data; 4
1 6. Operating Level Agreements (OLA's) guide our interaction with other internal teams; 4
2 1. one; 1
2 2. two; 2
2 3. three; 3
3 1. aaa; 1

好的，让我们看看。我不得不使用游标，因为这可能是通过C＃等编程语言更好地实现的，但是这里...使用Sql Server 2005，尝试以下方法。如果您需要任何解释，请告诉我。
DECLARE @Table TABLE(
QuestionSource VARCHAR(50),
QA VARCHAR(1000)
)
DECLARE @ReturnTable TABLE(
QuestionSource VARCHAR(50),
Question VARCHAR(1000),

)
DECLARE @XmlField XML,
@QuestionSource VARCHAR(40)
INSERT INTO @Table SELECT
'Availability','1. Our function has defined how Availability is measured the hardware/software in Production;#3#2. Availability threshold levels exist for our function (e.g., SLA''s);#3#3. Our function follows a defined process when there are threshold breaches;#4#4. Our function collects and maintains Availability data;#4#5. Comparative analysis helps identify trending with the Availability data;#4#6. Operating Level Agreements (OLA''s) guide our interaction with other internal teams;#4#'
INSERT INTO @Table SELECT
'Capacity', '1. Our function has defined how Availability is measured the hardware/software in Production;#1#2. Availability threshold levels exist for our function (e.g., SLA''s);#2#3.
