Question

我有一个存储过程，当运行时，从视图中初始插入aa表，然后是一个update语句，修改第一个select语句使用的视图中的表（代码如下）：

ALTER PROCEDURE [dbo].[LFC_sp_LIT_PgmrRequestForm] 
AS
BEGIN
    SET NOCOUNT ON;

    insert into firebird.helpdesk.dbo.tbl_program_request (Requester, Description, Priority, DateRequest,  project_status, department, category, requester_email, DueDate, Note)
    select dept_name, submitter_first_name + '-' + issue_description, severity_level, getdate(), 'Not Started', dept_name, issue_category, submitter_email, date_due, issue_details
    from ics_net..CUS_CF_PGMR_REQUEST_View
    where finalbalance = 0; 

    UPDATE ics_net..CF_Submission
    SET finalbalance = 5
    WHERE finalbalance = 0
    AND FormId = '79A807D9-230B-494C-A609-A284DBBE41B8';

END

每当提交Web表单时都会调用此过程，目标是将数据从Web表单数据库移动到我们的帮助台数据库中。 Web表单在数据库中具有最终余额字段，该字段设置为零。移动时，我们将其更新为非零数字。

第一个语句执行会发生什么，但第二个更新永远不会发生。一旦再次调用它，第一个语句就会执行，第二个语句适用于之前应该更新的语句。我试图解决这个问题的是：

对两个语句使用ROWLOCK提示
我已确保事务隔离级别为READ COMMITTED

除了在select语句中使用NOLOCK提示之外，我无法想到其他任何事情，但我对此非常犹豫。有任何想法吗？感谢。

编辑1）基于一些讨论，我想澄清一些事情：

任何表上都没有任何现有的触发器这个查询的基础。
初始选择基于视图，而第二次更新引用构成视图的表。

视图定义：

ALTER VIEW [dbo].[CUS_CF_PGMR_REQUEST_View] AS

 s.SubmittedDate,
 s.UserId,

视图背后的表定义

CREATE TABLE [dbo].[CF_Answers](
    [AnswerID] [uniqueidentifier] NOT NULL,
    [SubmissionID] [uniqueidentifier] NULL,
    [ItemID] [uniqueidentifier] NULL,
    [AnswerValue] [varchar](max) NULL,
    [MItemID] [uniqueidentifier] NULL,
    [RowIndex] [int] NULL,
    [ChildItemID] [uniqueidentifier] NULL,
    [DisplayText] [varchar](max) NULL,
    [NumericValue] [numeric](8, 2) NULL,
    [IsVisibleOnSubmit] [bit] NULL,
 CONSTRAINT [PK_CF_Answers] PRIMARY KEY CLUSTERED 
(
    [AnswerID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

CREATE TABLE [dbo].[CF_Submissions](
    [SubmissionID] [uniqueidentifier] NOT NULL,
    [UserID] [uniqueidentifier] NULL,
    [FormID] [uniqueidentifier] NULL,
    [SubmittedDate] [datetime] NULL,
    [FinalBalance] [decimal](18, 2) NULL,

) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

插入目标表的定义：

CREATE TABLE [dbo].[tbl_program_request](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [Requester] [nvarchar](50) NULL,
    [Description] [nvarchar](255) NULL,
    [Priority] [nvarchar](10) NULL,
    [DateRequest] [datetime] NULL,
    [WorkingOn] [nvarchar](30) NULL,
    [CompletedDate] [datetime] NULL,
    [StartDate] [nvarchar](15) NULL,
    [Note] [nvarchar](max) NULL,
    [project_status] [nvarchar](25) NULL,
    [hours_week] [decimal](4, 2) NULL,
    [hours_total] [decimal](10, 2) NULL,
    [department] [nvarchar](30) NULL,
    [category] [nvarchar](20) NULL,
    [requester_email] [nvarchar](30) NULL,
    [DueDate] [datetime] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

最后，从视图中提取的一些示例数据：

SubmissionId - B81CE5F8-A87B-42B1-9339-2B36166394AB
FormId - 79A807D9-230B-494C-A609-A284DBBE41B8
已提交日期 - 1/24/2018 16:43
UserId - 58E3958A-A786-4CB9-8EDE-0837ACE187BD
状态 - 1
submitter_first_name - SM
submitter_email - email @ organization
dept_name - LIT
date_due - 1/28/2018
issue_category -MISC
severity_level - LOW
issue_description - test3
issue_details - test3
FinalBalance - 0

只是为了澄清，在SP的末尾，FinalBalance应该等于5.但是，直到第二次运行它才会设置为5，导致双重插入到tbl_program_request表中。

存储过程在第二次运行之前不执行更新部分
