Dynamic Way To Transpose SQL Table Similar to Excel Functionality - sql

Question

I've looked around a good amount and haven't found quite the correct solution to what I think is a very simple problem. Everything I find focuses on one value being tranposed, but here I have a bunch.
I have this table currently and I want to transpose it exactly how Excel would. What is the easiest way to do this?
What I have:
nodeid | Headcount | FTE | Count of Part-Time Employees | Count of Non-Permanent Employees |
Actuals | 12 | 13 | 23 | 35 |
Targets | 15 | 15 | 25 | 25 |
What I want:
nodeid | Actuals | Targets |
Headcount | 12 | 15 |
FTE | 13 | 15 |
Count of Part-Time Employees | 23 | 25 |
Count of Non-Permanent Employees | 35 | 25 |

Answer 1

If 2016+, you can use a bit of JSON to "dynamically" unpivot your data, and then simply apply a PIVOT
Example
Declare #YourTable Table ([nodeid] varchar(50),[Headcount] int,[FTE] int,[Count of Part-Time Employees] int,[Count of Non-Permanent Employees] int) Insert Into #YourTable Values
('Actuals',12,13,23,35)
,('Targets',15,15,25,25)
Select *
From (
Select A.NodeID
,B.*
From #YourTable A
Cross Apply (
Select [Node] = [Key]
,[Value] = try_convert(int,Value)
From OpenJson( (Select A.* For JSON Path,Without_Array_Wrapper )) ) B
Where try_convert(int,value) is not null
) src
Pivot ( max(Value) for [NodeID] in ([Actuals],[Targets]) ) pvt
Order By Node desc
Returns
Node Actuals Targets
Headcount 12 15
FTE 13 15
Count of Part-Time Employees 23 25
Count of Non-Permanent Employees 35 25
Note: If <2016 there is an similar XML approach.

Answer 2

You can use unpivot and pivot to achieve that.
try the following:
DECLARE #tab TABLE
(nodeid VARCHAR(100),
Headcount INT,
FTE INT,
[Count of Part-Time Employees] INT,
[Count of Non-Permanent Employees] INT
);
INSERT INTO #tab SELECT 'Actuals', 12, 13, 23, 35;
INSERT INTO #tab SELECT 'Targets', 15, 15, 25, 25;
SELECT *FROM #tab;
DROP TABLE IF EXISTS #temp;
SELECT *
INTO #temp
FROM
(
SELECT nodeid,
Headcount,
FTE,
[Count of Part-Time Employees],
[Count of Non-Permanent Employees]
FROM #tab
) t UNPIVOT(val FOR col IN(Headcount,
FTE,
[Count of Part-Time Employees],
[Count of Non-Permanent Employees])) upvt;
DECLARE #collist VARCHAR(MAX);
SELECT #collist = STUFF(
(
SELECT DISTINCT ',' + QUOTENAME(nodeid)
FROM #temp
ORDER BY ',' + QUOTENAME(nodeid) FOR XML PATH('')
), 1, 1, '');
DECLARE #sql VARCHAR(MAX)= 'select col as nodeid, Actuals, Targets
from #temp t
pivot
(
max(val) for nodeid IN (' + #collist + ')
)pvt';
EXEC (#sql);
