cte tsql使用變量

Question

我有一個表函數，它包含一些CTE表，最終滾動到返回的select語句。在其中一個CTE表中，我使用@variable。它與我聲明的函數是相同的@變量。當我嘗試保存該函數時，出現此錯誤：

Lookup Error - SQL Server Database Error: Parameters were not supplied for the function 'forecast_baseline'. 

在CTE表中使用@variable有問題嗎？我可以提供代碼，但它似乎沒有將函數@variable傳遞給CTE表，因此編譯器不喜歡它。

ALTER function [eo].[forecast_baseline] (@monthkey as char(6)) 
    returns @results table(
    [billing_date] date, 
    [year] int, 
    [type] varchar(max),

Answer 1

錯誤是因爲您已命名爲CTE作爲您的函數名稱。更改第二個CTE名稱：

... 
WHERE 
DATEADD(month, @Interval, enddatetimemonth) < @EndTime 
), 

forecast_baseline (
... 

以任何其他名稱。

此外，您將需要使用UNION ALL而不是在結果表中單獨插入2個插入，因爲您只有1個可能性來查詢CTE。您無法多次查詢CTE。
