爲什麼光標顯示錯誤

Question

SQL Server上

工作2000年使用SQL Server工作Schedular.If我查詢分析器中運行的波紋管光標的語法比我沒有得到任何錯誤。但是當我設置SqlServer的試劑 - 這句法要自動電子郵件通知>喬布斯然後它是創建錯誤。

沒有錯誤消息，很難診斷問題。

老實說，代碼亂七八糟。這是內部文本的第一部分。我修正了遊標，你的迭代習慣用法，以及你的出生日期過濾。我不知道你想要做什麼w/@a，但它是錯誤的。

DECLARE 
    @out_desc VARCHAR(1000) 
, @out_mesg VARCHAR(10) 
, @name VARCHAR(20) 
, @birthdate datetime 
, @email NVARCHAR(50) 
, @body NVARCHAR(1000) 

-- Use a cursor variable for easier scoping: 
DECLARE @C1 CURSOR 

-- Since Birthdate = Today should be very selective, we 
-- use the STATIC keyword to materialize the results in tempdb 
-- before iteration. 
SET @C1 = CURSOR STATIC FOR 
    SELECT [Name],[BirthDate],[Email] 
    FROM Customers3 
    WHERE BirthDate = DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), 0) 


-- Since we used the STATIC keywork, calling OPEN will execute the SELECT statement above 
-- and materialize the results in tempdb. The cursor will then iterate over the materialized 
-- results in tempdb, rather than Customers3. 
OPEN @C1 

-- this is a better idiom for cursor iteration: one FETCH NEXT, rather then two 
-- and therefore fewer places you need to touch the code to make changes 
WHILE 1=1 BEGIN 
    FETCH NEXT FROM @C1 INTO @name, @birthdate, @email 
    IF @@FETCH_STATUS <> 0 BREAK 

    -- this is wrong, whatever you are trying to do. 
    Declare @a int 
    SELECT @a=count(*) FROM Customers where name like '%s%' 

    -- moved to the cursor WHERE clause. Why were you filtering on hour and minute? 
    -- IF DATEPART(DAY,@birthdate) = DATEPART(DAY,GETDATE()) 
    -- AND DATEPART(MONTH,@birthdate) = DATEPART(MONTH,GETDATE()) 
    --  AND DATEPART(hour,@birthdate) = DATEPART(hour,GETDATE()) 
    --  AND DATEPART(minute,@birthdate) = DATEPART(minute,GETDATE()) 
    -- BEGIN 

    -- to concatenant an INT, you must first convert it to a varchar 
    SET @body = '<b>HappyBirthday ' + @name + '</b><br />Many happy returns of the day'+CONVERT(VARCAR(30),@a)+'' 
    + '<br /><br />Customer Relationship Department'
