SQL Server Operand类型冲突:日期与int不兼容

sql

当我尝试执行此代码时,在“ with DateDimension”行出现错误:

消息206,级别16,状态2,第15行
操作数类型冲突:日期与int不兼容

这是我正在使用的SQL查询:

declare @DateCalendarStart  date,
        @DateCalendarEnd    date,
        @FiscalCounter      date,
        @FiscalMonthOffset  int;

set @DateCalendarStart = '2011-01-28';
set @DateCalendarEnd = '2012-10-26';


set @FiscalMonthOffset = 3;

with DateDimension //Error got this line

as

(
    select  @DateCalendarStart as DateCalendarValue,
            dateadd(m, @FiscalMonthOffset, @DateCalendarStart) as FiscalCounter

    union all

    select  DateCalendarValue + 1,
            dateadd(m, @FiscalMonthOffset, (DateCalendarValue + 1)) as FiscalCounter
    from    DateDimension 
    where   DateCalendarValue + 1 < = @DateCalendarEnd
)

您的问题在于该DateCalendarValue + 1部分。尝试使用DATEADD(),如下所示:

declare @DateCalendarStart  date,
        @DateCalendarEnd    date,
        @FiscalCounter      date,
        @FiscalMonthOffset  int;

set @DateCalendarStart = '2011-01-28';
set @DateCalendarEnd = '2012-10-26';

-- Set this to the number of months to add or extract to the current date to get the beginning 
-- of the Fiscal Year. Example: If the Fiscal Year begins July 1, assign the value of 6 
-- to the @FiscalMonthOffset variable. Negative values are also allowed, thus if your 
-- 2012 Fiscal Year begins in July of 2011, assign a value of -6.
set @FiscalMonthOffset = 3;

with DateDimension

as

(
    select  @DateCalendarStart as DateCalendarValue,
            dateadd(m, @FiscalMonthOffset, @DateCalendarStart) as FiscalCounter

    union all

    select  DATEADD(DAY, 1, DateCalendarValue), -- Using a DATEADD() function here works for SQL Server
            DATEADD(m, @FiscalMonthOffset, (DATEADD(DAY, 1, DateCalendarValue))) as FiscalCounter
    from    DateDimension 
    where   DATEADD(DAY, 1, DateCalendarValue) < = @DateCalendarEnd
)

SELECT * FROM DateDimension OPTION (MAXRECURSION 1000)

编辑:我不知道您的原始代码是否要使用该MAXRECURSION选项,但是如果您不知道我建议您阅读此内容。基本上,在这种情况下,这意味着您可以使用CTE列出1,000个日期。如果您需要的更多,则必须将其更改为1000以符合您的需求。
