Question

有没有办法扭转Oracle的Pivot函数使用的动态名称的顺序？

我有这个SQL语句，我必须对每个列重新别名，以便在末尾而不是在开头添加数字。这也要求我加倍引用实际的数据透视表列的名称。除了对列进行重新别名之外，还有更好的方法将数字附加到末尾吗？

  SELECT PrimaryKey
       , PRODUCT
       , "1_SEQ"  AS SEQ_1
       , "1_TYP"  AS TYP_1
       , "1_STA"  AS STA_1
       , "1_RES"  AS RES_1
       , "2_SEQ"  AS SEQ_2
       , "2_TYP"  AS TYP_2
       , "2_STA"  AS STA_2
       , "2_RES"  AS RES_2
       , "3_SEQ"  AS SEQ_3
       , "3_TYP"  AS TYP_3
       , "3_STA"  AS STA_3
       , "3_RES"  AS RES_3
       , "4_SEQ"  AS SEQ_4
       , "4_TYP"  AS TYP_4
       , "4_STA"  AS STA_4
       , "4_RES"  AS RES_4
       , "5_SEQ"  AS SEQ_5
       , "5_TYP"  AS TYP_5
       , "5_STA"  AS STA_5
       , "5_RES"  AS RES_5
    FROM (
        SELECT PrimaryKey
             , ForeignKey
             , Type
             , STATUS
             , RESULT
             , PRODUCT
             , ROW_NUMBER() OVER (PARTITION BY PrimaryKey ORDER BY ORDERNO, ForeignKey) NUM
          FROM STG_tbl
    )
    PIVOT (
       MAX(ForeignKey) AS SEQ
     , MAX(Type) as TYP
     , MAX(STATUS) AS STA
     , MAX(RESULT) AS RES
     FOR NUM IN (1,2,3,4,5)
    )

您可以添加别名，但这不会在列名后面加上数字：

@IBAction func toggleFlash() {
    if let device = AVCaptureDevice.defaultDevice(withMediaType: AVMediaTypeVideo), device.hasTorch {
    do {
        try device.lockForConfiguration()
        let torchOn = !device.isTorchActive
        try device.setTorchModeOnWithLevel(1.0)
        device.torchMode = torchOn ? .on : .off
        device.unlockForConfiguration()
    } catch {
        print("error")
    }
}
