SQL无法为时间维度表插入数据

Question

I am building a Data warehouse for my school project. I have already created my time dimension table and it works.

`  CREATE TABLE TimeDim(
   [timeCode] int primary key,
   [date] datetime,
   [year] char(4),
   [month] varchar(2),
   [monthName] varchar(9),
   [Quarter] varchar(9),
   [dayOfMonth] varchar(2),
   [dayName] varchar(9),
   [dayOfQuarter] varchar(3),
   [dayOfYear] varchar(3),
   [weekOfMonth] varchar(1),
   [weekOfQuarter] varchar(2),
   [weekOfYear] varchar(2));`

However, the errors occur when I try to create data in the Time Dimension table.The error shows: **

`Msg 213, Level 16, State 1, Line 95
Column name or number of supplied values does not match table definition.`

** The code for me to create data is

 DECLARE @StartDate DATETIME = '01/01/2003' --Starting value of Date Range
DECLARE @EndDate DATETIME = '01/01/2006' --End Value of Date Range ( end at 31/12/1999)

--Temporary Variables To Hold the Values During Processing of Each Date of Year
DECLARE
    @DayOfWeekInMonth INT,
    @DayOfWeekInYear INT,
    @DayOfQuarter INT,
    @WeekOfMonth INT,
    @CurrentYear INT,
    @CurrentMonth INT,
    @CurrentQuarter INT

/*Table Data type to store the day of week count for the month and year*/
DECLARE @DayOfWeek TABLE (DOW INT, MonthCount INT, QuarterCount INT, YearCount INT)

INSERT INTO @DayOfWeek VALUES (1, 0, 0, 0)
INSERT INTO @DayOfWeek VALUES (2, 0, 0, 0)
INSERT INTO @DayOfWeek VALUES (3, 0, 0, 0)
INSERT INTO @DayOfWeek VALUES (4, 0, 0, 0)
INSERT INTO @DayOfWeek VALUES (5, 0, 0, 0)
INSERT INTO @DayOfWeek VALUES (6, 0, 0, 0)
INSERT INTO @DayOfWeek VALUES (7, 0, 0, 0)

--Extract and assign various parts of Values from Current Date to Variable

DECLARE @CurrentDate AS DATETIME = @StartDate
SET @CurrentMonth = DATEPART(MM, @CurrentDate)
SET @CurrentYear = DATEPART(YY, @CurrentDate)
SET @CurrentQuarter = DATEPART(QQ, @CurrentDate)

/********************************************************************************************/

    IF @CurrentMonth != DATEPART(MM, @CurrentDate) 
    BEGIN
        UPDATE @DayOfWeek
        SET MonthCount = 0
        SET @CurrentMonth = DATEPART(MM, @CurrentDate)
    END

    BEGIN

        SET QuarterCount = 0
        SET @CurrentQuarter = DATEPART(QQ, @CurrentDate)
    END

        /* Check for Change in Year of the Current date if Year changed then change 
         Variable value*/


    IF @CurrentYear != DATEPART(YY, @CurrentDate)
    BEGIN

        SET YearCount = 0
        SET @CurrentYear = DATEPART(YY, @CurrentDate)
    END

        YearCount = YearCount + 1
    WHERE DOW = DATEPART(DW, @CurrentDate)

    SELECT
        @DayOfWeekInMonth = MonthCount,

        DATEPART(WW, @CurrentDate) + 1 - DATEPART(WW, CONVERT(VARCHAR, 
        DATEPART(MM, @CurrentDate)) + '/1/' + CONVERT(VARCHAR, 
        DATEPART(YY, @CurrentDate))) AS weekOfMonth,

        DATEPART(WW, @CurrentDate) AS weekOfYear,
        DATEPART(MM, @CurrentDate) AS month,
        DATENAME(MM, @CurrentDate) AS monthName,

        DATEPART(QQ, @CurrentDate) AS Quarter,

        DATEPART(YEAR, @CurrentDate) AS year


    SET @CurrentDate = DATEADD(DD, 1, @CurrentDate)
END

Answer 1

The Error is so clear:-

Column name or number of supplied values does not match table definition.

That means you trying insert number of values doesn't match with number of columns.

The number of Columns is 13 , as next:-

1. timeCode
2. date
3. year
4. month
5. monthName
6. Quarter
7. dayOfMonth
8. dayName
9. dayOfQuarter
10. dayOfYear
11. weekOfMonth
12. weekOfQuarter
13. weekOfYear

The number of values is 36 , as following:-

1. TimeKey
2. Date
3. FullDateUK
4. FullDateUSA
5. DayOfMonth
6. DaySuffix
7. DayName
8. DayOfWeekUSA
9. DayOfWeekUK
10. DayOfWeekInMonth
11. DayOfWeekInYear
12. DayOfQuarter
13. DayOfYear
14. WeekOfMonth
15. WeekOfQuarter
16. WeekOfYear
17. Month
18. MonthName
19. MonthOfQuarter
20. Quarter
21. QuarterName
22. Year
23. YearName
24. MonthYear
25. MMYYYY
26. FirstDayOfMonth
27. LastDayOfMonth
28. FirstDayOfQuarter
29. LastDayOfQuarter
30. FirstDayOfYear
31. LastDayOfYear
32. IsHolidayUSA
33. IsWeekday
34. HolidayUSA
35. (No column name)
36. (No column name)

UPDATE:-

After Editing the script , the error still existing, because the number of values is 15 as following:-

1. timeCode
2. date
3. FullDateUK
4. FullDateUSA
5. dayOfMonth
6. dayName
7. dayOfQuarter
8. dayOfYear
9. weekOfMonth
10. weekOfQuarter
11. weekOfYear
12. month
13. monthName
14. Quarter
15. year
