MS 服务器 2012

以下查询返回正确的数据，但我需要对其进行旋转，但我的尝试失败了，任何 hep 将不胜感激..

查询...

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'

结果...

TrialSampleID |ReferenceReadID |Reference_Antibiotic          |MIC          
CC-200001     | 4077           |Amikacin                      | = 8 ug/ml

CC-200001     | 4077           |Trimethoprim/Sulfamethoxazole | > 8 ug/ml

对于每个 TrialSampleID，该块重复 6 次，给出 6 个 MIC

我想要以下形式的数据，但当我对数据进行透视时，MIC 列中的数据为 NULL。

想要的……

试过了……

PIVOT(  
    MIN(ReferenceReadID)
    FOR MIC IN (
                MIC1,
                MIC2,
                MIC3,
                MIC4,
                MIC5,
                MIC6
                )   
    ) pivoted

这解决了它，感谢 D-Shih 的洞察力...
