Question

我有这个问题，我正试图逐字逐句地转换自己：

SELECT "Job_Operation"."Work_Center",
       "Job_Operation"."Job_Operation",
       "Job_Operation_Time"."Work_Date",
       "Job_Operation"."Est_Total_Hrs"."Job_Operation_Time"."Act_Run_Hrs",
       "Job_Operation_Time"."Act_Setup_Hrs",
       "Job",
       "Job"."Description",
       "Job_Operation_Time"."Overtime_Hrs"."Job_Operation_Time"."Act_Setup_Hrs",
       "Job"."Job",
       "Job"."Description",
       "Job_Operation_Time"."Labor_Burden",
       "Job_Operation"."Est_Setup_Labor",
       "Job_Operation"."Est_Run_Labor",
       "Job_Operation"."Est_Labor_Burden"."Job_Operation"."Operation_Service"
FROM {oj("Job" "Job"
  LEFT OUTER JOIN "Job_Operation" "Job_Operation"
    ON "Job"."Job"="Job_Operation"."Job")
  LEFT OUT JOIN "Job_Operation_Time" "Job_Operation_Time"
    ON "Job_Operation"."Job_Operation"."Job_Operation"="Job_Operation_Time"."Job_Operation"}

这就是我为MySql提出的：

SELECT Job_Operation.Work_Center,
       Job_Operation.Job_Operation,
       Job_Operation_Time.Work_Date,
       Job_Operation.Est_Total_Hrs.Job_Operation_Time.Act_Run_Hrs,
       Job_Operation_Time.Act_Setup_Hrs,
       Job,
       Job.Description,
       Job_Operation_Time.Overtime_Hrs.Job_Operation_Time.Act_Setup_Hrs,
       Job.Job,
       Job.Description,
       Job_Operation_Time.Labor_Burden,
       Job_Operation.Est_Setup_Labor,
       Job_Operation.Est_Run_Labor,
       Job_Operation.Est_Labor_Burden.Job_Operation.Operation_Service
FROM LEFT JOIN (Job LEFT JOIN Job_Operation ON Job.Job=Job_Operation.Job)
     LEFT JOIN Job_Operation_Time Job_Operation_Time
       ON Job_Operation.Job_Operation.Job_Operation=Job_Operation_Time.Job_Operation

但它显然不起作用。我哪里错了？有没有一个简单的工具来帮助这种事情？经过进一步调查，我意识到这是一个CRYSTAL REPORT QUERY，因为它不能在我的SQL服务器上工作。

在这里采取刺：

SELECT "Job_Operation"."Work_Center"
    ,"Job_Operation"."Job_Operation"
    ,"Job_Operation_Time"."Work_Date"
    ,"Job_Operation"."Est_Total_Hrs"
    ,"Job_Operation_Time"."Act_Run_Hrs"
    ,"Job_Operation_Time"."Act_Setup_Hrs"
    ,"Job"."Description"
    ,"Job_Operation_Time"."Overtime_Hrs"
    ,"Job_Operation_Time"."Act_Setup_Hrs"
    ,"Job"."Job"
    ,"Job_Operation_Time"."Labor_Burden"
    ,"Job_Operation"."Est_Setup_Labor"
    ,"Job_Operation"."Est_Run_Labor"
    ,"Job_Operation"."Est_Labor_Burden"
    ,"Job_Operation"."Operation_Service"
FROM "Job" AS "Job"
LEFT OUTER JOIN "Job_Operation" AS "Job_Operation" ON "Job"."Job" = "Job_Operation"."Job"
LEFT OUTER JOIN "Job_Operation_Time" AS "Job_Operation_Time" ON "Job_Operation"."Job_Operation" = "Job_Operation_Time"."Job_Operation"

我删除了尴尬的“某处这是专有的”语法，修复了几个应该是逗号的句点，将OUT更改为OUTER，并为表别名提供了AS语句。这应该符合ANSI标准，希望这会有所帮助。

修改

通过用引号括起来更新我的答案以逃避所有保留字。同时取消了Job.Description的双重选择。
