操作數類型衝突：int與uniqueidentifier不兼容。如何使唯一標識符的OUTPUT

Question

我想有這個過程，因爲能夠得到UNIQUEIDENTIFIER值的輸出正常工作，但是當我嘗試執行它給我的錯誤查詢

操作數類型衝突：int與uniqueidentifier不兼容

我嘗試過不同的事情，但無法找到解決方案。

這裏是我的代碼

-- ================================================= 
-- Example: [mob].[procedureName] 369, NULL, 23741, "somePath", "SomeName", "clientName", NULL 
-- Example: [mob].[procedureName] 
-- Example: [mob].[procedureName] 
-- ================================================= 
ALTER PROCEDURE [mob].[uspInsertEmail]  
(
@ParamCompany VARCHAR(50), 
@ParamDate DATETIME, 
@ParamCreatedBy VARCHAR(50), 
@ParamFilePath VARCHAR(200), 
@ParamFileName VARCHAR(100), 
@ParamClientFileName VARCHAR(100), 
@ParamGUID UNIQUEIDENTIFIER OUTPUT 
) 
AS 
DECLARE @GUID UNIQUEIDENTIFIER=NEWID() 

INSERT INTO [mob].[tblEmail] 
(   
[Company], 
[GuidString], 
[Date], 
[CreatedBy] 
) 
VALUES 
(   
@ParamCompany, 
@GUID, 
@ParamDate, 
@ParamCreatedBy 
)        
INSERT INTO [mob].[tblEmailAttachment] 
(   
[Email], 
[FilePath], 
[FileName], 
[ClientFileName], 
[CreatedBy] 
) 
VALUES     
(   
IDENT_CURRENT ('mob.tblEmail'),    
@ParamFilePath, 
@ParamFileName, 
@ParamClientFileName, 
@ParamCreatedBy 
) 

SELECT @GUID AS EmailGuid 
SET @ParamGUID = @GUID 

我讀，我需要做的UNIQUEIDENTIFIER是在OUTPUT條款，但不知道究竟如何使@GUID作爲OUTPUT

我會使這個簡單得多。像這樣的東西。

-- ================================================= 
-- Example: [mob].[procedureName] 369, NULL, 23741, "somePath", "SomeName", "clientName", NULL 
-- Example: [mob].[procedureName] 
-- Example: [mob].[procedureName] 
-- ================================================= 
ALTER PROCEDURE [mob].[uspInsertEmail]  
(
    @ParamCompany VARCHAR(50), 
    @ParamDate DATETIME, 
    @ParamCreatedBy VARCHAR(50), 
    @ParamFilePath VARCHAR(200), 
    @ParamFileName VARCHAR(100), 
    @ParamClientFileName VARCHAR(100), 
    @ParamGUID UNIQUEIDENTIFIER OUTPUT 
) 
AS 
    set nocount on; 

    select @ParamGUID = NEWID(); 

    INSERT INTO [mob].[tblEmail] 
    (   
     [Company], 
     [GuidString], 
     [Date], 
     [CreatedBy] 
    ) 
    VALUES 
    (   
     @ParamCompany, 
     @ParamGUID, 
     @ParamDate, 
     @ParamCreatedBy 
    )        

    INSERT INTO [mob].[tblEmailAttachment] 
    (   
     [Email], 
     [FilePath], 
     [FileName], 
     [ClientFileName], 
     [CreatedBy] 
    ) 
    VALUES     
    (   
     SCOPE_IDENTITY(),    
     @ParamFilePath, 
     @ParamFileName, 
     @ParamClientFileName, 
     @ParamCreatedBy 
    )
