How to Generate a 100-Year Calendar Table in SQL?

Creating a 100-year calendar table in SQL Server

The following generic script creates a calendar table spanning 100 years in SQL Server:

IF EXISTS (SELECT * FROM information_schema.tables WHERE Table_Name = 'Calendar' AND Table_Type = 'BASE TABLE')
BEGIN
    DROP TABLE [Calendar]
END

CREATE TABLE [Calendar] (
    [CalendarDate] DATETIME
)

DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME
SET @StartDate = GETDATE()
SET @EndDate = DATEADD(year, 100, @StartDate) -- 修改为100年

WHILE @StartDate <= @EndDate
BEGIN
    INSERT INTO [Calendar] (CalendarDate)
    SELECT @StartDate

    SET @StartDate = DATEADD(day, 1, @StartDate)
END

Remember to adjust the start and end dates in the script to your specific needs. This code will generate a calendar table containing 100 years of data.

For more advanced calendar implementation, you can refer to other scripts that generate complete calendars with various attributes such as year, quarter, week, date, and holiday.
