Question

我正在尝试根据CSV文件更新表格。我有CSV列表的Id和修剪编号，我需要根据SQL表中的特定ID更新修剪编号。

到目前为止我编写的脚本

-- Create a temporary table for the import
   drop table #InterpreterTrimNumbers
   CREATE TABLE #InterpreterTrimNumbers( 
  [SAPInterpreterId] int,
  TempTrimNumber varchar(100)
)

BEGIN TRANSACTION
  -- Bulk import into the temporary table
  BULK INSERT #InterpreterTrimNumbers FROM 'C:\CSVData\Trim numbers.csv' WITH (
    FIRSTROW = 2,
    FIELDTERMINATOR = ',',
    ROWTERMINATOR = '\n',
    ERRORFILE = 'C:\CSVData\Trim numbers-errors.csv',
    TABLOCK
  )

  update Interpreters set TrimNumber = (select TempTrimNumber from #InterpreterTrimNumbers where #InterpreterTrimNumbers.SAPInterpreterId = Interpreters.SAPInterpreterID )
  Commit Transaction

即使CSV文件只有110条记录，这一行也会返回1824行。我只想用特定的SAPInterpreterID

更新记录

感谢任何帮助。

Answer 1

假设您只有110个记录插入临时表，而且这些ID在Interpreters表中是唯一的，那么这个语法应该是这样的

UPDATE i 
SET TrimNumber = tempintr.TempTrimNumber
FROM Interpreters AS i INNER JOIN 
     #InterpreterTrimNumbers tempintr
     ON i.TrimNumber= tempintr.TempTrimNumber

您的查询无法正常工作的原因是因为它试图更新Interpreters表中的每个数字。如果与临时表匹配，那么这就是您所需要的。但是当没有匹配时，您的查询将返回NULL，导致不匹配的记录更新为NULL。
