Izskatījis 29 dažādus ierakstus, par uzvarētāju pasludinu Bilu Szisu! Bils ir viens no tiem cilvēkiem, kuram ērti rakstīt vaicājumus, neizmantojot Power Query saskarni. Viņš raksta: “To var izdarīt desmitiem veidu. Es jums sūtu četrus. ”
Jums vajadzētu lejupielādēt Bill's risinājumus un iziet cauri tiem pa vienam solim, izmantojot rūti Applied Steps.
Bila vienkāršākais risinājums ir Transponēšanas metode. Viss sarkanais ir kods, kuru Bils mainīja vai uzrakstīja ar roku:
let Source = Excel.CurrentWorkbook()((Name="UglyData"))(Content), #"Transposed Table" = Table.Transpose(Source), #"Promoted Headers" = Table.PromoteHeaders(#"Transposed Table", (PromoteAllScalars=true)), #"Added Index" = Table.AddIndexColumn(#"Promoted Headers", "Indeks", 0, 1), #"Integer-Divided Column" = Table.TransformColumns(#"Added Index", (("Indeks", each Number.IntegerDivide(_, 5), Int64.Type))), #"Grouped Rows" = Table.Group(#"Integer-Divided Column", ("Indeks"), (("tbl", each Table.Skip(_, 1), type table), ("Name", each _(0)(Category Description), type text))), #"Filtered Rows" = Table.SelectRows(#"Grouped Rows", each ((Name) "Dept. Total")), #"Expanded (0)" = Table.ExpandTableColumn(#"Filtered Rows", "tbl", Table.ColumnNames(#"Promoted Headers")), #"Removed Columns" = Table.RemoveColumns(#"Expanded (0)",("Indeks")), #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Removed Columns", ("Category Description", "Name"), "Atrybut", "Wartość"), #"Pivoted Column" = Table.Pivot(#"Unpivoted Other Columns", List.Distinct(#"Unpivoted Other Columns"(#"Category Description")), "Category Description", "Wartość", List.Sum), #"Inserted Sum" = Table.AddColumn(#"Pivoted Column", "Total", each List.Sum(((Q1), (Q2), (Q3), (Q4))), type number), #"Renamed Columns" = Table.RenameColumns(#"Inserted Sum",(("Atrybut", "Category Description"))) in #"Renamed Columns" Apvienotajai metodei Bils saka, ka tas parāda M valodu. Bet viņš to neizmantotu profesionālā lietojumā. Tomēr tikai ar četrām M koda rindiņām tas ir iespaidīgs. Viss sarkanajā rakstīts ar roku:
let Source = Table.PromoteHeaders(Excel.CurrentWorkbook()((Name="UglyData"))(Content) , (PromoteAllScalars=true)), Lists = Table.FromColumns((List.Transform((0… ((List.Count(Table.ColumnNames(Source))-6)/5)-1), each List.Range(Table.ColumnNames(Source), _*5+6, 5)) )), AlmostReady = Table.Combine(Table.AddColumn(Lists, "Columns", each Table.FromColumns((Table.Column(Source, Table.ColumnNames(Source)(0))) & (List.Repeat(((Column1)(0)), Table.RowCount(Source))) & List.Transform(List.Skip((Column1), 1), each Table.Column(Source, _)), (Table.ColumnNames(Source)(0), "Name") & List.Transform(List.Skip((Column1), 1), each Text.BeforeDelimiter(_, "_")) ) )(Columns)), Ready = Table.AddColumn(AlmostReady, "Total", each List.Sum(List.Skip(Record.ToList(_), 2))) in Ready Bila palīga tabulas metode ir rakstīta daļēji ar roku:
let Source = Excel.CurrentWorkbook()((Name="UglyData"))(Content), #"Promoted Headers" = Table.PromoteHeaders(Source, (PromoteAllScalars=true)), HelperTbl = Table.FromColumns((List.Skip(Table.ColumnNames(#"Promoted Headers"), 1), List.Transform((0… List.Count(Table.ColumnNames(#"Promoted Headers"))-2), each Number.IntegerDivide(_, 5)))), #"Grouped Rows" = Table.Group(HelperTbl, ("Column2"), (("tbl", each Table.TransformColumnNames(Table.SelectColumns(#"Promoted Headers", _(Column1) & (Table.ColumnNames(#"Promoted Headers")(0))), each Text.BeforeDelimiter(_, "_")), type table))), Combined = Table.Combine(Table.AddColumn(#"Grouped Rows", "Tables", (x) => Table.SelectColumns(Table.AddColumn(x(tbl), "Name", each Table.ColumnNames(x(tbl))(0)), List.Skip(Table.ColumnNames(x(tbl)), 1) & ("Name")) ) (Tables)), #"Filtered Rows" = Table.SelectRows(Combined, each ((Name) "Dept. Total")), #"Removed Other Columns" = Table.SelectColumns(#"Filtered Rows",List.LastN(Table.ColumnNames(#"Filtered Rows"), 2) & List.RemoveLastN(Table.ColumnNames(#"Filtered Rows"), 2)) in #"Removed Other Columns"Bila pēdējā metodē tiek izmantota fxUnpivot funkcija, kuru viņš rakstīja jau sen.
