我想在我的表中插入一个数据行，名称为：DSKWOR00，但出现此错误：

字符串或二进制数据将被截断。

所以我关闭了 ANSI_WARNINGS 并插入了行但结果不是我的值

这是我的 T-SQL ：

1 - 创建我的表：

CREATE TABLE [dbo].[DSKWOR00](   [DSW_ID] [nvarchar](10) NULL,    [DSW_YY] [float] NOT NULL,    [DSW_MM] [float] NOT NULL,    [DSW_LISTNO] [nvarchar](12) NULL,    [DSW_ID1] [nvarchar](8) NULL,    [DSW_FNAME] [nvarchar](60) NULL,    [DSW_LNAME] [nvarchar](60) NULL,    [DSW_DNAME] [nvarchar](60) NULL,    [DSW_IDNO] [nvarchar](15) NULL,    [DSW_IDPLC] [nvarchar](30) NULL,    [DSW_IDATE] [nvarchar](8) NULL,    [DSW_BDATE] [nvarchar](8) NULL,    [DSW_SEX] [nvarchar](3) NULL,    [DSW_NAT] [nvarchar](10) NULL,    [DSW_OCP] [nvarchar](50) NULL,    [DSW_SDATE] [nvarchar](8) NULL,    [DSW_EDATE] [nvarchar](8) NULL,    [DSW_DD] [float] NULL,    [DSW_ROOZ] [float] NULL,    [DSW_MAH] [float] NULL,    [DSW_MAZ] [float] NULL,    [DSW_MASH] [float] NULL,    [DSW_TOTL] [float] NULL,    [DSW_BIME] [float] NULL,    [DSW_PRATE] [float] NULL,    [DSW_JOB] [nvarchar](6) NULL,    [PER_NATCOD] [nvarchar](10) NOT NULL, CONSTRAINT [PK_DSKWOR00] PRIMARY KEY CLUSTERED(    [DSW_YY] ASC,    [DSW_MM] ASC,    [PER_NATCOD] Asc ) ON [PRIMARY]) ON [PRIMARY] 

2 - 在我的表中插入一行：

INSERT INTO dbo.DSKWOR00
(DSW_ID,DSW_YY,DSW_MM,DSW_LISTNO,DSW_ID1,DSW_FNAME,DSW_LNAME,DSW_DNAME,DSW_IDNO,DSW_IDPLC,DSW_IDATE,DSW_BDATE,DSW_SEX,DSW_NAT,DSW_OCP,DSW_SDATE,DSW_EDATE,DSW_DD,DSW_ROOZ,DSW_MAH,DSW_MAZ,DSW_MASH,DSW_TOTL,DSW_BIME,DSW_PRATE,DSW_JOB,PER_NATCOD) 
VALUES 
('6773790024',1401,1,1,'80079349','¤ç¬ üóä','ö‘þõþîž','‘®¤þóä','1011','¢¥þ','0','¢¤õ','ü÷¤þ',' ñõ‘ä ¤þ¢õ',0,0,'0','0','0','0','0','0','0','0',0,'OZ0509','4430928460')

3 - 如果我使用 ANSI_WARNINGS ON 插入错误：

Msg 8152, Level 16, State 30, Line 3
String or binary data would be truncated.
--Note: My insert is correct I don't know why I'm seeing this error

4 - 所以为了修复错误，我这样做了：

SET ANSI_WARNINGS OFF

INSERT INTO dbo.DSKWOR00
(DSW_ID,DSW_YY,DSW_MM,DSW_LISTNO,DSW_ID1,DSW_FNAME,DSW_LNAME,DSW_DNAME,DSW_IDNO,DSW_IDPLC,DSW_IDATE,DSW_BDATE,DSW_SEX,DSW_NAT,DSW_OCP,DSW_SDATE,DSW_EDATE,DSW_DD,DSW_ROOZ,DSW_MAH,DSW_MAZ,DSW_MASH,DSW_TOTL,DSW_BIME,DSW_PRATE,DSW_JOB,PER_NATCOD) 
VALUES 
('6773790024',1401,1,1,'80079349','¤ç¬ üóä','ö‘þõþîž','‘®¤þóä','1011','¢¥þ','0','¢¤õ','ü÷¤þ',' ñõ‘ä ¤þ¢õ',0,0,'0','0','0','0','0','0','0','0',0,'OZ0509','4430928460')

SET ANSI_WARNINGS ON

5 -最后我的行将插入，但它不是我插入表中的值！

---- My Values in Inser :  ('6773790034',1401,1,1,'80069349','¤ç¬ üóä','ö‘þõþîž','‘®¤þóä','1011','¢¥þ','0','¢¤õ','ü÷¤þ',' ñõ‘ä ¤þ¢õ',0,0,'0','0','0','0','0','0','0','0',0,'OZ0509','4430928444')
---- What did Insert :       6773790034  1401 1 1  80069349   ¤ç¬? ü??     ?‘???î?   ‘®¤???    1011  ¢¥?    0  ¢¤?    ü÷?           ??‘? ¤?¢?  0 0  0   0   0   0   0   0   0   0  0  OZ0509   4430928444

我想在我的表中防止删除、插入、更新和选择的并发，所以我尝试SERIALIZABLE在事务之前使用表，但这并没有为其他进程锁定表！如何解决？

我尝试了什么：

1- 创建 Table_1

    --Create Sample Table
CREATE TABLE [dbo].[Table_1](
    [Number] [bigint] NOT NULL,
    [Price] [bigint] NULL,
 CONSTRAINT [PK_Table_1] PRIMARY KEY CLUSTERED 
(
    [Number] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
INSERT [dbo].[Table_1] ([Number], [Price]) VALUES (1, 1000)
GO
INSERT [dbo].[Table_1] ([Number], [Price]) VALUES (2, 3000)
GO
INSERT [dbo].[Table_1] ([Number], [Price]) VALUES (3, 8000)
GO

2- 延迟查询会话一：

--SESSION 1
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;

WAITFOR DELAY '00:00:10.000'
UPDATE Table_1 SET Price = 6000 WHERE NUMBER = 1
SELECT * FROM Table_1

COMMIT TRANSACTION;

3-查询会话二，这个查询最多等待会话一直到结束进程，但事实并非如此！：

--SESSION 2 
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;

SELECT * FROM Table_1

COMMIT TRANSACTION;
