我在插入多个表但在

下面获得异常时为句柄事务创建了SP

我的SP

ALTER PROCEDURE [dbo].[usp_Insert_BankData]
@xmlBankItems   XML ,
@xmlAccDetails XML,
@xmlPosition XML

DECLARE @TranStarted   bit

    IF( @@TRANCOUNT = 0 )
        BEGIN
            BEGIN TRANSACTION
            SET @TranStarted = 1
        END
    ELSE
        SET @TranStarted = 0

    INSERT INTO BankItem([BankItemId],[PortfolioId],[ItemIdentifier],[ItemDisplayName])
    SELECT  r.value('BankItemId[1]','uniqueidentifier'),r.value('PortfolioId[1]','uniqueidentifier'),
            r.value('ItemIdentifier[1]','bigint'),r.value('ItemDisplayName[1]','varchar(150)')
    FROM @xmlBankItems.nodes('bankItem') t(r)


    INSERT INTO BankAccountDetails (BankAccountId,BankItemId, AccountName,AccountDescription)

使用FK关系在单个事务中插入多个表
