Create hierarchical formatted output from table - sql-server-2008

Question

I have a SQL table like this:
CC Descr C_NO Vol Wt
2050 Des1 123 20 40
2060 Des2 123 30 50
2050 Des1 125 20 40
2060 Des2 125 30 50
2050 Des1 126 20 40
and I want output like this:
2050
Des1
123
20
40
125
20
40
126
20
40
2060
Des2
123
30
50
125
30
50
How can I do that using TSQL code?
For every similar CC value which always have similar Descr value, it shows all the C_No, Vol and Wt values related to that particular CC value in the sequence written in the output section.

Answer 1

Try this
DECLARE #t TABLE
(
CC BIGINT,
Descr NVARCHAR(10),
C_NO INT,
Vol SMALLINT,
WT SMALLINT
)
INSERT INTO #t(CC,Descr,C_NO,Vol,WT)
VALUES (2050,'Des1',123,20,40)
,(2060,'Des2',123,30,50)
,(2050,'Des1',125,20,40)
,(2060,'Des2',125,30,50)
,(2050,'Des1',126,20,40)
;WITH CTE1 AS(
SELECT
t1.CC
,t1.Descr
,MergedColumn = STUFF(
(SELECT
','
+ CAST(C_NO AS VARCHAR(10)) + '/' + CAST(Vol AS VARCHAR(10)) + '/' + CAST(Wt AS VARCHAR(10))
FROM #t AS t2
WHERE t2.CC=t1.CC AND t2.Descr=t2.Descr
FOR XML PATH('')),1,1,'')
FROM #t t1
GROUP BY t1.CC,t1.Descr)
,CTE2 AS
(
SELECT
X.CC
,X.Descr
,Y.SplitDataByComma
FROM
(
SELECT
*,
CAST('<X>'+REPLACE(F.MergedColumn,',','</X><X>')+'</X>' AS XML) AS xmlfilter
FROM CTE1 F
)X
CROSS APPLY
(
SELECT fdata.D.value('.','varchar(50)') AS SplitDataByComma
FROM X.xmlfilter.nodes('X') AS fdata(D)
)Y
)
,CTE3 AS
(
SELECT
X.CC
,X.Descr
,Y.SplitDataBySlash
, X.SplitDataByComma AS GrpID
,ROW_NUMBER() OVER( PARTITION BY X.SplitDataByComma ORDER BY X.CC,X.Descr ) AS Rn
,X.SplitDataByComma + CAST(CC AS Varchar(200)) + CAST(Descr AS Varchar(200)) CC_Descr
FROM
(
SELECT
*,
CAST('<X>'+REPLACE(F.SplitDataByComma,'/','</X><X>')+'</X>' AS XML) AS xmlfilter
FROM CTE2 F
)X
CROSS APPLY
(
SELECT fdata.D.value('.','varchar(50)') AS SplitDataBySlash
FROM X.xmlfilter.nodes('X') AS fdata(D)
)Y
)
,CTE4 AS
(
SELECT
Rn = ROW_NUMBER() OVER(PARTITION BY CC ORDER BY CC)
,CC
,Descr
,CASE WHEN Rn = 1 THEN CAST (SplitDataBySlash AS VARCHAR(10)) ELSE ' ' END C_NO
,CASE WHEN Rn = 1 THEN ' ' ELSE CAST (SplitDataBySlash AS VARCHAR(10)) END Vol_Wt
,GrpID
FROM Cte3
)
,CTE5 AS(
SELECT
CC = CASE WHEN Rn > 1 THEN ' ' ELSE CAST(CC AS Varchar(200)) END
,Descr = CASE WHEN Rn > 1 THEN ' ' ELSE CAST(Descr AS Varchar(200)) END
,C_NO
,Vol_Wt
,GrpID
FROM Cte4)
SELECT
CHAR(10)
+ REPLICATE(SPACE(1),10)
+ CAST(CC as VARCHAR(100))
+ CHAR(10)
+ REPLICATE(SPACE(1),15)
+ Descr
+ CHAR(10)
+ REPLICATE(SPACE(1),10)
+ C_NO
+ CHAR(10)
+ REPLICATE(SPACE(1),15)
+ Vol_Wt
FROM CTE5
In Text Mode(CTRL + T), the result is
2050
Des1
123
20
40
125
20
40
126
20
40
2060
Des2
123
30
50
125
30
50
And in Grid Mode(CTRL + D) , the result is
(No column name)
2050
Des1
123
20
40
125
20
40
126
20
40
2060
Des2
123
30
50
125
30
50
However, SQL Server (or any database) is not the place to do formatting as others spoke about.Please look into the matter.

Answer 2

I wouldn't do this. TSQL is used to get the data, then you format that data with application code.
But if you're working in Query analyzer and just want the output there, you can try the following:
DECLARE mytable_cursor CURSOR FOR
SELECT CC, Descr, C_NO, Vol, Wt
FROM myTable
ORDER BY CC, Descr, C_NO
OPEN mytable_cursor;
FETCH NEXT FROM mytable_cursor
INTO #CC, #Descr, #C_NO, #Vol, #Wt
SET #oCC = #CC
SET #oDescr = #Descr
SET #oC_NO = #C_NO
WHILE ##FETCH_STATUS = 0
BEGIN
PRINT #CC;
WHILE ##FETCH_STATUS = 0 AND #oCC = #CC
BEGIN
PRINT ' ' + #Descr;
WHILE ##FETCH_STATUS = 0 AND #oDescr = #Descr
BEGIN
PRINT ' ' + #C_NO;
WHILE ##FETCH_STATUS = 0 AND #oC_NO = #C_NO
BEGIN
PRINT ' ' + #Vol;
PRINT ' ' + #WT;
FETCH NEXT FROM mytable_cursor
INTO #CC, #Descr, #C_NO, #Vol, #Wt
END
SET #oC_NO = #C_NO
END
SET #oDescr = #Descr
END
SET #oCC = #CC
END
CLOSE mytable_cursor;
DEALLOCATE mytable_cursor;
Or you can use a GROUP BY ... WITH ROLLUP and CASE WHEN to get the results a single query.
Here's an example with dashes instead of spaces to make sure the formatting is visible:
SELECT (CASE
WHEN Descr IS NULL THEN CC
WHEN C_NO IS NULL THEN '----' + Descr
WHEN Vol IS NULL THEN '--' + C_NO
WHEN Wt IS NULL THEN '------' + Vol
ELSE '------' + Wt
END)
FROM
(SELECT CC, Descr, C_NO, Vol, Wt
FROM my
GROUP BY CC, Descr, C_NO, Vol, Wt
WITH ROLLUP) AS x
WHERE CC IS NOT NULL
ORDER BY CC, Descr, C_NO, Vol, Wt

Answer 3

You can't do this in tsql code. You need to do this sort of thing in the application code.

Answer 4

One of the best way to represent data in hierarchical order is using XML. Something more, often the use of XML is connected with great performance.
Using your example information and this peace of code:
;WITH DistinctValues (CC,Descr ) AS
(
SELECT DISTINCT CC,Descr
FROM #TableOne
)
SELECT (
SELECT CC AS "CC/#CC"
,Descr AS "CC/Descr"
,(
SELECT C_NO AS "C_NO/#C_NO",
Vol AS "C_NO/Vol",
Wt AS "C_NO/Wt"
FROM #TableOne AS Data
WHERE Data.CC=DV.CC AND Data.Descr=DV.Descr
FOR XML PATH(''),TYPE
) AS "CC"
FROM DistinctValues AS DV
FOR XML PATH(''),TYPE
)
FOR XML PATH('Source'),TYPE
I get the following result (in the form of one row return by the statement above):
<Source>
<CC CC="2050">
<Descr>Des1</Descr>
<C_NO C_NO="123">
<Vol>20</Vol>
<Wt>40</Wt>
</C_NO>
<C_NO C_NO="125">
<Vol>20</Vol>
<Wt>40</Wt>
</C_NO>
<C_NO C_NO="126">
<Vol>20</Vol>
<Wt>40</Wt>
</C_NO>
</CC>
<CC CC="2060">
<Descr>Des2</Descr>
<C_NO C_NO="123">
<Vol>30</Vol>
<Wt>50</Wt>
</C_NO>
<C_NO C_NO="125">
<Vol>30</Vol>
<Wt>50</Wt>
</C_NO>
</CC>
</Source>
Note that the XML functions in T-SQL combined with the XML language structure gives you a huge of possible variations of output data formats - you use one or many nodes, you can represent the the data as attributes or node text. Combine this as you like and as you feel it will be easiest to work with in your application level.
Here is the whole code (just copy and paste) that I have used to generated the previous XML structure:
DECLARE #TableOne TABLE
(
CC BIGINT,
Descr NVARCHAR(10),
C_NO INT,
Vol SMALLINT,
WT SMALLINT
)
INSERT INTO #TableOne(CC,Descr,C_NO,Vol,WT)
VALUES (2050,'Des1',123,20,40)
,(2060,'Des2',123,30,50)
,(2050,'Des1',125,20,40)
,(2060,'Des2',125,30,50)
,(2050,'Des1',126,20,40)
;WITH DistinctValues (CC,Descr ) AS
(
SELECT DISTINCT CC,Descr
FROM #TableOne
)
SELECT (
SELECT CC AS "CC/#CC"
,Descr AS "CC/Descr"
,(
SELECT C_NO AS "C_NO/#C_NO",
Vol AS "C_NO/Vol",
Wt AS "C_NO/Wt"
FROM #TableOne AS Data
WHERE Data.CC=DV.CC AND Data.Descr=DV.Descr
FOR XML PATH(''),TYPE
) AS "CC"
FROM DistinctValues AS DV
FOR XML PATH(''),TYPE
)
FOR XML PATH('Source'),TYPE
This works like a charm and it is tested on Microsoft SQL Server Management Studio 2012.
