Question

我已经创建了一个用于发送短信的存储过程，并在更新触发器上调用它

这是我的程序：

ALTER PROCEDURE dbo.[spSendSmsSQL] 
    @Mobile varchar(20), 
    @smstext as varchar(200)
AS
BEGIN
    DECLARE @iReq int, @hr int 
    DECLARE @sUrl AS varchar(500) 
    DECLARE @errorSource VARCHAR(8000)
    DECLARE @errorDescription VARCHAR(8000) 

    EXEC @hr = sp_OACreate 'Microsoft.XMLHTTP', @iReq OUT        

    print @hr        

    if @hr <> 0     
        RAISERROR('sp_OACreate Microsoft.XMLHTTP FAILED!', 16, 1) 

    SET @sUrl = 'http://url?numbers=#MobNo#&message=#Msg#';
    SET @sUrl = REPLACE(@sUrl,'#MobNo#',@Mobile) 
    SET @sUrl = REPLACE(@sUrl,'#Msg#',@smstext) 

    -- sms code start 
    EXEC @hr = sp_OAMethod @iReq, 'Open', NULL, 'GET', @sUrl, true 

    IF @hr <> 0 
        RAISERROR('sp_OAMethod Open FAILED!', 16, 1) 

    EXEC @hr = sp_OAMethod @iReq, 'send' 

    SELECT @iReq

    IF @hr <> 0 
    BEGIN 
        EXEC sp_OAGetErrorInfo @iReq, @errorSource OUTPUT, @errorDescription OUTPUT

        SELECT 
            [Error Source] = @errorSource,
            [Description] = @errorDescription

        RAISERROR('sp_OAMethod Send FAILED!', 16, 1) 
    END 
    ELSE 
        EXEC @hr = sp_OAGetProperty @iReq 
END

通过

调用时工作正常

EXEC spSendSmsSQL '9999999999','SMS FROM SQLSERVER'

但是当我从触发器调用它时会导致

引发错误“sp_OAMethod打开FAILED！” AND“sp_OAMethod Send FAILED！”

我的触发器是：

请在我错的地方帮助我。

我知道这是我的愚蠢，但我通过检查@oReference解决了。 oReference值为null，当我连接时@sms为NULL并引发错误。

  IF @oReference IS NULL
        SET @oReference='';
    SET @sms ='RECHARGE ' + @rStatus + ' AND CONFIRM. Number: ' + @rMobile + ' Amt: ' + CONVERT(char(6), @amount) + ' TR-ID = '+ @oReference +' . Balance is ' + CONVERT(char(10), @balance);
    EXEC spSendSmsSQL @mobile, @sms;

从SQL Server存储过程发送SMS并触发失败
