我使用Power Query来提取上个月测试的所有唯一项类型:

let
  Source = Sql.Database("XXX", "YYY"),
  dbo_tblTest = Source{[Schema="dbo",Item="tblTest"]}[Data],
  #"Filtered Rows" = Table.SelectRows(dbo_tblTest, each Date.IsInPreviousNMonths([Test_Stop], 1)),
  #"Added Custom" = Table.AddColumn(#"Filtered Rows", "Custom", each Text.Start([Item],5)),
  #"Removed Duplicates" = Table.Distinct(#"Added Custom", {"Custom"})
in
  #"Removed Duplicates"

要得到:

1. Test_ID ---项目--- Test_Start --- Test_Stop ---自定义
