SQL query to display year values which lie between two date values

Hello

I am looking for a SQL query to display year values which are between two date values.
This is what my database looks like and this is what I need:

 
SELECT
ID,
StartDate,
DueDate
FROM dbo.Test

This is not a Power Query question. It is not even a Power BI question. This is a T-SQL question and involves a CROSS JOIN (Cartesean Product). But here you go:

 

Create Table #MyTemp ( BudgetYear INT)

INSERT INTO #MyTemp (BudgetYear) VALUES (2021), (2022), ...<end of your range)

 

SELECT Id, StartDate, DueDate, BudgetYear

FROM dbo.Test

CROSS JOIN #MyTemp

WHERE BudgetYear >= MIN(YEAR(StartDate))

AND BudgetYear <= MAX(YEAR(DueDate))

 

DROP TABLE #MyTemp

 

Note: The CROSS JOIN will return one row for every combination of both tables. If you have 50 rows in one table and 10 rows in the second, your result set will be 500 rows. 

 

Hope that helps. If not, please explain the 'rules' for any one Test row to be matched to a Budget Year.

Hi @Flixy04 ,

 

Since this is a posting in the powerquery forum, I'm assuming it's a related thread. 
Please refer to the following steps:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTIyMDLUNQAhCMdU19BI19hQKVYnWskIImSELG8Mk48FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, StartDate = _t, DueDate = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"StartDate", type date}, {"DueDate", type date}}),
    AddYearsList = Table.AddColumn(#"Changed Type", "BudgetYearList", each List.Transform({Number.From([StartDate])..Number.From([DueDate])}, each Date.From(_))),
    ExpandYearsList = Table.ExpandListColumn(AddYearsList, "BudgetYearList"),
    AddBudgetYear = Table.AddColumn(ExpandYearsList, "BudgetYear", each Date.Year([BudgetYearList])),
    RemoveBudgetYearList = Table.RemoveColumns(AddBudgetYear,{"BudgetYearList"}),
    #"Removed Duplicates" = Table.Distinct(RemoveBudgetYearList)
in
    #"Removed Duplicates"

Output:

SQL:

WITH YearsCTE (ID, StartDate, DueDate, BudgetYear) AS (
  SELECT ID, StartDate, DueDate, YEAR(StartDate) AS BudgetYear
  FROM your_table
  UNION ALL
  SELECT ID, StartDate, DueDate, BudgetYear + 1
  FROM YearsCTE
  WHERE BudgetYear < YEAR(DueDate)
)
SELECT * FROM YearsCTE
ORDER BY ID, BudgetYear;

I presume you want Power Query code. If yes, use this

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTIyMDLUNQAhCMdU19BI19hQKVYnWskIImSELG8Mk48FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, StartDate = _t, DueDate = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"StartDate", type date}, {"DueDate", type date}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "BudgetYear", each {Date.Year([StartDate])..Date.Year([DueDate])}),
    #"Expanded BudgetYear" = Table.ExpandListColumn(#"Added Custom", "BudgetYear")
in
    #"Expanded BudgetYear"
