有没有办法使用 WHERE 语句更新这些记录？

UPDATE HRBIQuery SET HRBIQuery.PaySegmentMultiplier = '1.35', 
    HRBIQuery.PaySegmentMultiplier = '1.25', HRBIQuery.PaySegmentMultiplier = '1.15',
    HRBIQuery.PaySegmentMultiplier = '.90', HRBIQuery.PaySegmentMultiplier = '.60',
    HRBIQuery.PaySegmentMultiplier = '.40' 
WHERE (HRBIQuery.BasePayRangeSegment = 'Below segment 1' AND HRBIQuery.PayGroupCountryDesc = 'France',
    HRBIQuery.BasePayRangeSegment = 'S1' AND HRBIQuery.PayGroupCountryDesc = 'France',
    HRBIQuery.BasePayRangeSegment = 'S2' AND HRBIQuery.PayGroupCountryDesc = 'France',
    HRBIQuery.BasePayRangeSegment = 'S3' AND HRBIQuery.PayGroupCountryDesc = 'France',
    HRBIQuery.BasePayRangeSegment = 'S4' AND HRBIQuery.PayGroupCountryDesc = 'France',
    HRBIQuery.BasePayRangeSegment = 'S5' AND HRBIQuery.PayGroupCountryDesc = 'France');

谢谢！

你在这里有几个选择。
选项 1：在查询中使用 switch 语句。

UPDATE HRBIQuery SET HRBIQuery.PaySegmentMultiplier =
  switch(HRBIQuery.BasePayRangeSegment = 'Below segment 1',1.35,
  HRBIQuery.BasePayRangeSegment = 'Below segment 1',1.35,
  HRBIQuery.BasePayRangeSegment = 'S1',1.25,
  HRBIQuery.BasePayRangeSegment = 'S2',1.15,
  HRBIQuery.BasePayRangeSegment = 'S3',.90,
  HRBIQuery.BasePayRangeSegment = 'S4',.60,
  HRBIQuery.BasePayRangeSegment = 'S5',.40)

WHERE HRBIQuery.BasePayRangeSegment IN('Below segment 1','S1','S2','S3','S4','S5') 
  AND HRBIQuery.PayGroupCountryDesc = 'France'

选项 2：使用嵌套 IIF 语句的一个查询。

UPDATE HRBIQuery SET HRBIQuery.PaySegmentMultiplier =
  IIF(HRBIQuery.PaySegmentMultiplier='Below segment 1',1.35,
  IIF(HRBIQuery.PaySegmentMultiplier='S1',1.25,
  IIF(HRBIQuery.PaySegmentMultiplier='S2',1.15,
  IIF(HRBIQuery.PaySegmentMultiplier='S3,.90,
  IIF(HRBIQuery.PaySegmentMultiplier='S4',.60,
  IIF(HRBIQuery.PaySegmentMultiplier='S1',.40))))))

WHERE HRBIQuery.BasePayRangeSegment IN('Below segment 1','S1','S2','S3','S4','S5') 
  AND HRBIQuery.PayGroupCountryDesc = 'France'

选项 3：使用 6 个不同的查询。我不会把所有六个都打出来。希望你明白这一点。

UPDATE HRBIQuery SET HRBIQuery.PaySegmentMultiplier = 1.35
WHERE HRBIQuery.BasePayRangeSegment  = 'Below segment 1'
  AND HRBIQuery.PayGroupCountryDesc = 'France'

选项 4：使用自定义函数。创建一个公共函数并在您的查询中调用它。

UPDATE HRBIQuery SET HRBIQuery.PaySegmentMultiplier = custom_function(HRBIQuery.BasePayRangeSegment)

WHERE HRBIQuery.BasePayRangeSegment IN('Below segment 1','S1','S2','S3','S4','S5') 
  AND HRBIQuery.PayGroupCountryDesc = 'France'

自定义函数应该是这样的（对不起任何语法错误，但你应该明白）：

public function custom_function(value)
  dim return_value as double 
  select case value
     case 'Below segment 1'
       return_value = 1.35
     case 's1'
       return_value = 1.25
     case 'S2'
       return_value = 1.15
     case 'S3'
       return_value = .90
     case 'S4'
       return_value = .60
     case 'S5'
       return_value = .40
  End select
  return return_value
end function
