Sql server 在SQL中插入多个值，转换失败

我有一个SQL表：

CREATE TABLE [jato].[option_list](
    [vehicle_id] [bigint] NOT NULL,
    [option_id] [int] NOT NULL,
    [option_type] [varchar](10) NULL,
    [option_code] [varchar](255) NULL,
    [manuf_name] [nvarchar](255) NULL,
    [id_902] [float] NULL,
    [id_903] [float] NULL,
    [id_904] [float] NULL,
    [id_905] [float] NULL,
    [id_100902] [float] NULL,
    [id_100903] [float] NULL,
    [id_100904] [float] NULL,
    [id_100905] [float] NULL,
 CONSTRAINT [PK_OPTIONLIST] PRIMARY KEY CLUSTERED 
(
    [vehicle_id] ASC,
    [option_id] 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

我想在其中插入值

以下查询工作正常：

INSERT INTO jato.option_list 
(vehicle_id,option_id,option_type,option_code,manuf_name,id_902,id_903,id_904,id_905,id_100902,id_100903,id_100904,id_100905) 

values
(11280320191201,1142,'C','MG','Machine Grey Metallic',0,0,0,0,0,0,0,0)

但如果我在同一个查询中添加其他值，我会遇到从

varchar

到int的转换失败，而我的列顺序没有改变。例如，以下查询不起作用，我在SQL将“MG”转换为int时出错：

INSERT INTO jato.option_list 
(vehicle_id,option_id,option_type,option_code,manuf_name,id_902,id_903,id_904,id_905,id_100902,id_100903,id_100904,id_100905) 

values
(11280320191201,1142,'C','MG','Machine Grey Metallic',0,0,0,0,0,0,0,0),
(11688620170510,1190,'O',881,'Automatic boot pull down',635.25,525,0,0,635.25,525,0,0) 

我不明白我做错了什么

有人知道吗？

那么， 我找到了答案。我必须为所有行键入相同格式的值

就我而言：

INSERT INTO jato.option_list 
(vehicle_id,option_id,option_type,option_code,manuf_name,id_902,id_903,id_904,id_905,id_100902,id_100903,id_100904,id_100905) 

values
(11280320191201,1142,'C','MG','Machine Grey Metallic',0,0,0,0,0,0,0,0),
(11688620170510,1190,'O',881,'Automatic boot pull down',635.25,525,0,0,635.25,525,0,0) 

必须是：

INSERT INTO jato.option_list 
(vehicle_id,option_id,option_type,option_code,manuf_name,id_902,id_903,id_904,id_905,id_100902,id_100903,id_100904,id_100905) 

values
(11280320191201,1142,'C','MG','Machine Grey Metallic',0,0,0,0,0,0,0,0),
(11688620170510,1190,'O','881','Automatic boot pull down',635.25,525,0,0,635.25,525,0,0)

我不得不在881附近添加一些引号。

您的问题在于第二行值：

(11688620170510,1190,'O',881,'Automatic boot pull down',635.25,525,0,0,635.25,525,0,0)

改为：

(11688620170510,1190,'O','881','Automatic boot pull down',635.25,525,0,0,635.25,525,0,0)

那就行了。总之，您的代码应该如下所示：

INSERT INTO dbo.option_list 
(vehicle_id,option_id,option_type,option_code,manuf_name,id_902,id_903,id_904,id_905,id_100902,id_100903,id_100904,id_100905) 

values
(11280320191201,1142,'C','MG','Machine Grey Metallic',0,0,0,0,0,0,0,0),
(11688620170510,1190,'O','881','Automatic boot pull down',635.25,525,0,0,635.25,525,0,0)

语句中出现错误的实际原因是您使用了

VALUES

表值构造函数。在这种情况下，如中所述，多行INSERT语句中指定的值遵循UNION ALL语法的数据类型转换属性。这会导致将不匹配的类型隐式转换为优先级更高的类型

因此，对于问题中的数据，第一行的值

'MG'

（

varchar

）被隐式转换为

int

，因为第二行有

881

（

int

），并且

int

数据类型的顺序高于

varchar

数据类型

通过以下方式之一执行

INSERT

语句：

• 使用单个语句和apprapriate

  varchar

  数据类型（列

  选项的值
  'MG'
  和
  '881'
  ）

• 使用两个单独的语句和

  varchar

  和

  int

  数据类型（列

  选项的值
  'MG'
  和
  881
  ）

带有适当数据类型的单个

INSERT

语句：

INSERT INTO dbo.option_list 
(vehicle_id,option_id,option_type,option_code,manuf_name,id_902,id_903,id_904,id_905,id_100902,id_100903,id_100904,id_100905) 
VALUES
   (11280320191201,1142,'C','MG','Machine Grey Metallic',0,0,0,0,0,0,0,0),
   (11688620170510,1190,'O','881','Automatic boot pull down',635.25,525,0,0,635.25,525,0,0)

两条插入语句：

INSERT INTO dbo.option_list (vehicle_id,option_id,option_type,option_code,manuf_name,id_902,id_903,id_904,id_905,id_100902,id_100903,id_100904,id_100905) 
VALUES
   (11280320191201,1142,'C','MG','Machine Grey Metallic',0,0,0,0,0,0,0,0)

INSERT INTO dbo.option_list (vehicle_id,option_id,option_type,option_code,manuf_name,id_902,id_903,id_904,id_905,id_100902,id_100903,id_100904,id_100905)
VALUES
   (11688620170510,1190,'O',881,'Automatic boot pull down',635.25,525,0,0,635.25,525,0,0)
