Question

MS Server 2012

The following query returns the correct data but i need to pivot it and my attempts are failing, any hep would be appreciated..

Query...

SELECT TrialSampleID, ReferenceReadID, Reference_Antibiotic, CONCAT(Reference_Qualifier, ' ', Reference_MIC, ' ug/ml') AS 'MIC' FROM dbo.ClinicalTrial JOIN dbo.ReferenceDataPointers ON ClinicalTrial.ID = ReferenceDataPointers.ClinicalTrialID JOIN dbo.ReferencePlates ON ReferenceDataPointers.ReferenceSetID = ReferencePlates.ReferenceSetID JOIN dbo.ReferenceReads ON ReferencePlates.ID = ReferenceReads.ReferencePlateID JOIN dbo.ReferenceMICs ON ReferenceReads.ID = ReferenceMICs.ReferenceReadID WHERE TrialSampleID NOT LIKE 'REF-%' AND SpecimenSource LIKE 'Clinical%' AND Reference_ValidAntibiotic = 'True '

Result...

TrialSampleID |ReferenceReadID |Reference_Antibiotic          |MIC          
CC-200001     | 4077           |Amikacin                      | = 8 ug/ml
CC-200001     | 4077           |Ampicillin                    | > 64 ug/ml
CC-200001     | 4077           |Aztreonam                     | > 64 ug/ml
CC-200001     | 4077           |Cefazolin                     | > 16 ug/ml
CC-200001     | 4077           |Cefepime                      | = 64 ug/ml
CC-200001     | 4077           |Ceftazidime                   | > 64 ug/ml
CC-200001     | 4077           |Ceftazidime/Avibactam         | ≤ 2 ug/ml
CC-200001     | 4077           |Ertapenem                     | ≤ 0.125 ug/ml
CC-200001     | 4077           |Gentamicin                    | > 32 ug/ml
CC-200001     | 4077           |Levofloxacin                  | = 8 ug/ml
CC-200001     | 4077           |Meropenem                     | ≤ 0.125 ug/ml
CC-200001     | 4077           |Meropenem/Vaborbactam         | ≤ 0.5 ug/ml
CC-200001     | 4077           |Piperacillin/Tazobactam       | = 128 ug/ml
CC-200001     | 4077           |Trimethoprim/Sulfamethoxazole | > 8 ug/ml

The block repeats 6 times for each TrialSampleID giving 6 MICs

I would like the data in the following form but end up with NULL in the MIC column when i pivot the data.

Desired...

TrialSampleID |ReferenceReadID |Reference_Antibiotic          |MIC1             |MIC2               |MIC3

Answer 1

You can try to use condition aggregate function to make it.

CASE WHEN with MAX function.

SELECT  TrialSampleID,
        ReferenceReadID,
        Reference_Antibiotic,
        MAX(CASE WHEN rn = 1 THEN MIC END) 'MIC1',
        MAX(CASE WHEN rn = 2 THEN MIC END) 'MIC2',
        MAX(CASE WHEN rn = 3 THEN MIC END) 'MIC3',
        MAX(CASE WHEN rn = 4 THEN MIC END) 'MIC4',
        MAX(CASE WHEN rn = 5 THEN MIC END) 'MIC5',
        MAX(CASE WHEN rn = 6 THEN MIC END) 'MIC6'
FROM (
SELECT 
    TrialSampleID,
    ReferenceReadID,
    Reference_Antibiotic,
    CONCAT(Reference_Qualifier, ' ', Reference_MIC, ' ug/ml') AS 'MIC',
    ROW_NUMBER() OVER(PARTITION BY TrialSampleID,ReferenceReadID,Reference_Antibiotic ORDER BY Reference_Antibiotic) rn
FROM 
    dbo.ClinicalTrial
    JOIN dbo.ReferenceDataPointers ON ClinicalTrial.ID = ReferenceDataPointers.ClinicalTrialID
    JOIN dbo.ReferencePlates ON ReferenceDataPointers.ReferenceSetID = ReferencePlates.ReferenceSetID
    JOIN dbo.ReferenceReads ON ReferencePlates.ID = ReferenceReads.ReferencePlateID
    JOIN dbo.ReferenceMICs ON ReferenceReads.ID = ReferenceMICs.ReferenceReadID
WHERE 
    TrialSampleID NOT LIKE 'REF-%' 
    AND SpecimenSource LIKE 'Clinical%'
    AND Reference_ValidAntibiotic = 'True'
) t1
