Question

任何人都请指出为什么我会收到此错误？

SELECT imax, iResult
FROM(
    SELECT 
        top 20000 CAST(Pro_PCT AS INT), 
        CAST(REPLACE(Max_Off,'%','') AS INT) AS 'iMax',
        iif(CAST(Pro_PCT AS INT)> CAST(
    REPLACE(Max_Off,'%','') AS INT),'Yes','No') AS 'iResult'
FROM 
    dbo.FO_Entry) AS TableA
WHERE iResult = 'yes'

Answer 1

我会改用case表达式：

SELECT imax, iResult
FROM( SELECT TOP (20000) CAST(Pro_PCT AS INT) AS Pro_PCT,  CAST(REPLACE(Max_Off,'%','') AS INT) AS iMax,
             (CASE WHEN CAST(Pro_PCT AS INT) > CAST(REPLACE(Max_Off,'%','') AS INT) 
                   THEN 'Yes' ELSE 'No' 
              END) AS iResult
      FROM dbo.FO_Entry
    ) AS TableA
WHERE iResult = 'yes';

Answer 2

您缺少列名CAST（Pro_PCT AS INT），这就是该错误的原因：

const md = {
    "37aa0778-c148-4c04-b239-18885d46a8b0": 0,
    "869a7967-ffb3-4a20-b402-ad6d514472de": 0,
    "92c0f155-ce82-4b50-821f-439428c517a3": 0,
    "aa9eb0f2-35af-469a-8893-fc777b444bed": 0,
    "967d63ea-492c-4475-8b08-911be2d0bf22": 0,
    "47ec8d60-1fa2-4bf5-abc8-34df6bd53079": 0,
    "92c0f155-ce82-4b50-821f-439428c517a3": 0
};
for (const {created_at, created_by_id} of DailyLogs) {
  if (created_at >= this.state.startMonth && created_at <= this.state.finishMonth && md.hasOwnProperty(created_by_id)) {
      md[created_by_id]++;
  }
}

没有为“ TableA”的column1指定列名
