TRANCOUNT不匹配

Question

这是我正在使用的示例存储过程

CREATE PROCEDURE [dbo].[CreateCustomer]
        @firstName nvarchar(50) = null,
        @lastName nvarchar(50) = null,
        @emailAddress nvarchar(50),
        @contactNumber varchar(15) =null,
        @street1 nvarchar(50) = null,
        @street2 nvarchar(50) = null,
        @city nvarchar(50) = null,
        @State nvarchar(50)= null,
        @Country nvarchar(50)=null,
        @postalCode varchar(5) = null,
        @middleName nvarchar(50),
        @password nvarchar(50),
        @membershipExpieryDate datetime,
        @status int OUT

    AS
        BEGIN TRY
            BEGIN TRANSACTION
            SAVE TRANSACTION initialP
                DECLARE @lastAccessed datetime = GETDATE()
                DEClARE @uniqueCustomerID UNIQUEIDENTIFIER= NEWID()
                BEGIN TRANSACTION
                    INSERT INTO Customers(CustomerID, FirstName, LastName, EmailAddress, LastAccessed, ContactNumber, 
                        Street1, Street2, City, State, Country, PostalCode, MiddleName, Password, MembershipExpieryDate)
                        VALUES(@uniqueCustomerID,@firstName, @lastName, @emailAddress, @lastAccessed, @contactNumber, @street1, @street2,
                         @city, @State, @Country, @postalCode, @middleName, @password, @membershipExpieryDate)



     INSERT INTO Roles(CustomersCustomerID,Role) VALUES(@uniqueCustomerID,'V') 
            COMMIT

            SELECT CustomerID, FirstName, LastName, EmailAddress, LastAccessed, ContactNumber, 
                Street1, Street2, City, State, Country, PostalCode, MiddleName, MembershipExpieryDate FROM Customers WHERE EmailAddress = @emailAddress  

        SET @status =1
        COMMIT
    END TRY 
    BEGIN CATCH
        IF(@@TRANCOUNT > 0)
        BEGIN
            ROLLBACK TRANSACTION initialP
        END
        SET @status =2
    END CATCH

这是我用来获取查询数据的代码：

ObjectParameter status = new ObjectParameter("status", typeof(int));
var dataSet = Entity.CreateCustomer(newCustomer.FirstName, newCustomer.LastName,
newCustomer.EmailAddress, newCustomer.ContactNumber, newCustomer.Street1, newCustomer.Street2,
newCustomer.City, newCustomer.State, newCustomer.Country, newCustomer.PostalCode, newCustomer.MiddleName,
newCustomer.Password, newCustomer.MembershipExpieryDate, status);

但是当执行此存储过程时，它会给出一个错误，指出Trans count不匹配。 据我所知trans count在begin transaction出现时被commit所取代。当CREATE PROCEDURE dbo.TestForCommit ( @test11 int, @test111 int, @status int OUTPUT ) AS begin try declare @test1 uniqueidentifier = NEWID() begin transaction insert into TestT1(Test1, Test11, Test111) values(@test1, @test11, @test111) commit select Test1, Test11, Test111 from TestT1 where Test1 = @test1 SET @status = 1 end try begin catch Rollback Transaction set @status =2 end catch /* SET NOCOUNT ON */ RETURN 出现时，由{1}进行描述。 我已经在函数导入中映射了该函数，因为它可以返回复杂类型。

我无法理解这个问题。对我来说似乎很好。我想知道天气我这样做是否正确与一些细节。感谢。

编辑： 这是我通过编写示例代码发现的。我首先想到的是开始跨行动和提交。但事实并非如此。 它允许选择甚至在提交语句之前插入的值（如果我错了，请纠正我。）。 我创建了一个包含3列的测试表（test1唯一标识符，test2 int，test3 int） 并且我创建了一个存储过程调用Test： 其内容如下：

            ObjectParameter status = new ObjectParameter("status", typeof(int));
            SchoolEntities test = new SchoolEntities();
            var dataSet = test.TestForCommit(1, 1, status);
                //A:
                //(XXXXXXXXXXXXX)Console.WriteLine((int)status.Value);
                foreach (var item in dataSet)
                {
                    TestForCommit_Result t = item;
                    Console.WriteLine("{0} , {1} , {2}", t.Test1, t.Test11, t.Test111);

                }
                //B:
                Console.WriteLine((int)status.Value);
                Console.ReadLine();

我在实体模型中创建了一个功能导入，我就像这样使用它：

{{1}}

此// A：部分导致问题。这给出了一个空引用异常。但是// B：部分工作并给出状态值。我仍然在寻找它为什么这样工作。谢谢！ 的

我的建议。 （将Xact_Abort设置为开启）

Begin Try
    Set NoCount On
    Set Xact_Abort On
    Begin Tran
        --Your Query
    Commit Tran
End Try

Begin Catch
    Rollback Tran
End Catch
