Question

我寫了以下stored procedure，但它給出了錯誤，我如何使它正常工作。謝謝。

/* stored procedure interestcalc writen by M */ 
SET ANSI_NULLS ON 

SET QUOTED_IDENTIFIER ON 

CREATE PROCEDURE spInterestCal

    @P_NO INT, 
    @TOTAL_MONEY INT,

    @INTEREST_RATE INT, 
    @START_DATE DATE, 
    @END_DATE DATE,

似乎有4個錯誤解析查詢時 - 自己嘗試解析它在SQL Server Management Studio中，您將看到：

Msg 102, Level 15, State 1, Procedure spInterestCal, Line 13 
Incorrect syntax near ')'. 

Msg 111, Level 15, State 1, Procedure spInterestCal, Line 18 
'CREATE/ALTER PROCEDURE' must be the first statement in a query batch. 

Msg 1046, Level 15, State 1, Procedure spInterestCal, Line 74 
Subqueries are not allowed in this context. Only scalar expressions are allowed. 

Msg 102, Level 15, State 1, Procedure spInterestCal, Line 79 
Incorrect syntax near 'GO'. 

還有似乎是一些邏輯錯誤，你會如果沒有先解決上述問題就無法檢測到。

要糾正在第一解析錯誤，只需刪除從參數列表的末尾虛假逗號（注意到刪除逗號）：

@END_DATE DATE 

第二個錯誤也直線前進，把GO後SET QUOTED_IDENTIFIER ON和前CREATE PROCEDURE：

SET QUOTED_IDENTIFIER ON 
GO 

您PRINT聲明，其中包含一個SELECT DAY(@START_DATE)聲明接下來的關注 - 這是不允許的，應該b E法除去：

DAY(@START_DATE) 

最後一個發生，因爲你必須在你的程序結束END GO在一行。嘗試：

END 
GO 

Answer 2

我看到兩個語法錯誤：

1）附近有語法錯誤）「。刪除最後一個參數後的逗號：@END_DATE

2）在此上下文中不允許使用子查詢。只有標量表達式允許

PRINT ' P_NO IS ' + @P_NO + ' TOTAL_MONEY IS ' + @TOTAL_MONEY + ' 
    INSTALLMET AMOUNT IS ' + @TOTAL_MONEY/@R_INSTALLMENT_NUMBER + ' @INTEREST IS '+ 
    @INTEREST + ' DUE DATE IS '+ 
    (SELECT DAY(@START_DATE)) + '/' + (@SMOUNT) + '/' +(@SYEAR) 

取下(SELECT DAY(@START_DATE))SELECT只有具備' DUE DATE IS '+DAY(@START_DATE) + '/'
