How can i convert below using PIVOT
as
Thanks
I don't know if you can do that with the SQL Server PIVOT function. That function always assumes and requires some kind of an aggregate function (COUNT, AVG) on a numeric value - you can't just transpose rows to columns.
In your case, if you know your error fields in advance, you could do something like this:
SELECT
ErrorKey,
[Field1] AS Field1, [Field2] AS Field2, [Field10] AS Field10,
[Field11] AS Field11, [Field13] as Field13, [Field14] as Field14,
[Field15] as Field15, [Field21] as field21
FROM
(SELECT ErrorKey, ErrorField, ErrorValue
FROM Errors) e
PIVOT
(
COUNT (ErrorValue)
FOR ErrorField IN
( [Field1], [Field2], [Field10], [Field11], [Field13],
[Field14], [Field15], [Field21] )
) AS pvt
ORDER BY pvt.ErrorKey
This would produce an output something like this:
ErrorKey Field1 Field2 Field10 Field11 Field13 Field14 Field15 field21
1 1 1 1 0 0 0 0 0
2 0 0 0 1 1 1 0 0
3 0 0 0 0 0 0 1 1
This would give you the count of error in a particular field, for each error key.
It`s a bit messy, but here it is.
First of all I use the rank() function to know the position (1,2 or 3) of the ErrorField. With all that, I use that number for the Pivot. You need two pivots and a join between them.
WITH AuxTable (Data_Error_Key, ErrorField, ErrorValue, NumeroError)
AS
(
SELECT Data_Error_Key, ErrorField, ErrorValue, RANK() OVER (PARTITION BY Data_Error_Key ORDER BY Data_Error_Key, ErrorField)
FROM dbo.TempTable
)
SELECT TablaErrorField.Data_Error_Key, ErrorField1, ErrorValue1,ErrorField2,ErrorValue2, ErrorField3,
ErrorValue3
FROM
(
SELECT Data_Error_Key, [1] as ErrorField1, [2] as ErrorField2, [3] as ErrorField3
FROM (
SELECT Data_Error_Key,NumeroError, ErrorField
FROM AuxTable) P
PIVOT
(
MAX (ErrorField)
FOR NumeroError IN ([1], [2], [3])
) AS pvt) As TablaErrorField
INNER JOIN
(
SELECT Data_Error_Key, [1] as ErrorValue1, [2] as ErrorValue2, [3] as ErrorValue3
FROM (
SELECT Data_Error_Key,NumeroError, ErrorValue
FROM AuxTable) P
PIVOT
(
MAX (ErrorValue)
FOR NumeroError IN ([1], [2], [3])
) AS pvt) as TablaErrorValue
ON TablaErrorField.Data_Error_Key= TablaErrorValue.Data_Error_Key
All this assuming you need only 3 pairs of ErrorField/ErrorValue. Otherwise, you should take a look at my response in this question.
