在遊標聲明處傳遞一個變量爲「select」語句的可能性

我已經在sql server中創建了一個表值函數，並且我在變量中存儲了一個'select'statemetn作爲傳遞變量的遊標聲明，它顯示我錯誤。在遊標聲明處傳遞一個變量爲「select」語句的可能性

我的錯誤是

Incorrect syntax near '@QUERY'.

我的功能是

CREATE FUNCTION WEEKLY_REPORT(@START_DATE DATETIME, @END_DATE DATETIME,@PRACTISE NVARCHAR(MAX)) 
RETURNS @WEEKLY_REPORT_DETAILS_INFORMATION TABLE 
(
    RESOURCE_NAME NVARCHAR(MAX),

    DAY4 DECIMAL(5,2), 
    DAY5 DECIMAL(5,2), 
    DAY6 DECIMAL(5,2), 
    DAY7 DECIMAL(5,2), 
    UTILIZATION INT

[在存儲過程中使用動態SQL遊標]的可能重複（HTTP select語句：//stackoverflow.com/questions/1045880/using-a-cursor-with-dynamic-sql-in-a-stored-procedure） – cfeduke 2013-03-14 00:12:40

你不能以這種方式聲明遊標。您必須編寫select語句，而不是使用select語句字符串傳遞變量。

請參閱文檔以獲取更多信息。 DECLARE CURSOR (Transact-SQL)

嘗試再進行一次臨時表和光標之前執行你的@QUERY比寫光標和臨時表
