SQL Server-执行存储过程后出错

Question

When executing my stored procedure, why do I get the following error message?

Msg 266, Level 16, State 2, Procedure spAddCustomer, Line 0 [Batch Start Line 21]
Transaction count after EXECUTE indicates a mismatching number of BEGIN and COMMIT statements. Previous count = 1, current count = 2.

Anything help, thanks.

Stored procedure code:

CREATE PROC spAddCustomer
    @FirstName VARCHAR = INPUT,
    @LastName VARCHAR = INPUT,
    @EmailAddress VARCHAR = INPUT,
    @PhoneNumber VARCHAR = INPUT
AS
BEGIN TRY
BEGIN TRANSACTION 
    INSERT INTO sales.CustomerPII (FirstName, LastName, EmailAddress, PhoneNumber)
    VALUES (@FirstName, @LastName, @EmailAddress, @PhoneNumber);

    COMMIT TRANSACTION
END TRY
BEGIN CATCH
--Rows inserted still exist
--SELECT ERROR_NUMBER()
    --ROLLBACK TRANSACTION --Any transaction work will be undone
END CATCH;

Executed

EXEC spAddCustomer 'FirstTest', 'LastTest', 'EmailTest', 'AddressTest';

Answer 1

取消注释此行：

ROLLBACK TRANSACTION --Any transaction work will be undone

Answer 2

Try setting XACT_ABORT ON in the stored procedure. When SET XACT_ABORT is ON and T-SQL statement raises a run-time error, SQL Server automatically rolls back the current transaction. Try it as follows:

USE AdventureWorks2016CTP3
GO
CREATE PROC spAddCustomer
@FirstName varchar = INPUT,
@LastName varchar = INPUT,
@EmailAddress varchar = INPUT,
@PhoneNumber varchar = INPUT
AS

SET NOCOUNT ON 
SET XACT_ABORT ON
BEGIN TRY
BEGIN TRANSACTION 
INSERT INTO sales.CustomerPII (FirstName,LastName,EmailAddress,PhoneNumber)
VALUES(@FirstName, @LastName, @EmailAddress, @PhoneNumber);
COMMIT TRANSACTION
END TRY
BEGIN CATCH

END CATCH;
