我有一个三列 18 行的表。我想变成两行的 18 列。这是桌子

类别乐队积分
 20_CAT1 21-22 10
 20_CAT2 23-25 20
 20_CAT3 26- 30
 30_CAT1 31-33 10
 30_CAT2 34-38 20
 30_CAT3 39- 30
 40_CAT1 41-44 5
 40_CAT2 45-50 15
 40_CAT3 51- 25
 50_CAT1 50-55 5
 50_CAT2 56-63 15
 50_CAT3 64- 25
 60_CAT1 61-66 5
 60_CAT2 67-75 20
 60_CAT3 76- 30
 70_CAT1 71-77 5
 70_CAT2 78-88 20
 70_CAT3 89- 30

新表应将“类别”作为列，将“带”和“点”作为行

我不确定如何使用 Cross Apply 和 Pivot 来执行此操作，或者即使这是正确的方法。

提前致谢。

我已经设法在不使用 PIVOT 的情况下使以下工作。

        SELECT
        MAX(CASE WHEN Category = '20_CAT1' THEN Bands END) [20_CAT1_Bands],
        MAX(CASE WHEN Category = '20_CAT1' THEN Points END) [20_CAT1_Points],
        MAX(CASE WHEN Category = '20_CAT2' THEN Bands END) [20_CAT2_Bands],
        MAX(CASE WHEN Category = '20_CAT2' THEN Points END) [20_CAT2_Points],
        MAX(CASE WHEN Category = '20_CAT3' THEN Bands END) [20_CAT3_Bands],
        MAX(CASE WHEN Category = '20_CAT3' THEN Points END) [20_CAT3_Points],

        MAX(CASE WHEN Category = '30_CAT1' THEN Bands END) [30_CAT1_Bands],
        MAX(CASE WHEN Category = '30_CAT1' THEN Points END) [30_CAT1_Points],
        MAX(CASE WHEN Category = '30_CAT2' THEN Bands END) [30_CAT2_Bands],
        MAX(CASE WHEN Category = '30_CAT2' THEN Points END) [30_CAT2_Points],
        MAX(CASE WHEN Category = '30_CAT3' THEN Bands END) [30_CAT3_Bands],
        MAX(CASE WHEN Category = '30_CAT3' THEN Points END) [30_CAT3_Points],

        MAX(CASE WHEN Category = '40_CAT1' THEN Bands END) [40_CAT1_Bands],

        MAX(CASE WHEN Category = '50_CAT3' THEN Points END) [50_CAT3_Points],

        MAX(CASE WHEN Category = '60_CAT1' THEN Bands END) [60_CAT1_Bands],
        MAX(CASE WHEN Category = '60_CAT1' THEN Points END) [60_CAT1_Points],

        MAX(CASE WHEN Category = '60_CAT3' THEN Points END) [60_CAT3_Points],
