nvarchar值'3001822585'的转换溢出了一个int列

Question

我使用以下将Excel文件导入SQL Server.

Excel文件的所有值都是字符串.我能够导入除了文件Barcode,SalePrice和Price2.我收到错误

nvarchar值'3001822585'(条形码)的转换溢出了一个int列

码:

         SqlCommand sqlcmd = new SqlCommand
         (@"MERGE Inventory AS target
         USING (SELECT
            LocalSKU, ItemName, QOH, Price, Discontinued,Barcode, Integer2
            ,Integer3, SalePrice, SaleOn, Price2 FROM @source)
            AS Source ON (Source.LocalSKU = target.LocalSKU)
           WHEN MATCHED THEN
           UPDATE 
           SET ItemName = source.ItemName,
           Price = source.Price,
           Discontinued = source.Discontinued,
           Barcode = source.Barcode,
           Integer2 = source.Integer2,
           Integer3 = source.QOH,
           SalePrice = source.SalePrice,
           SaleOn = source.SaleOn,
           Price2 = source.Price2;", sqlconn);

           SqlParameter param;
           param = sqlcmd.Parameters.AddWithValue("@source", dr);
           param.SqlDbType = SqlDbType.Structured;
           param.TypeName = "dbo.InventoryType";

           sqlconn.Open();
           sqlcmd.ExecuteNonQuery();
           sqlconn.Close();

数据库::

 LocalSKU varchar(200),
 ItemName varchar(200),
 QOH int,
 Price decimal(19,4),
 Discontinued bit,
 Barcode int,
 Integer2 int,
 Integer3 int,
 SalePrice decimal(19,4),
 SaleOn bit,
 Price2 decimal(19,4)

dbo.InventoryType 是:

   CREATE TYPE [dbo].[InventoryType] AS TABLE
   (
      [LocalSKU] [varchar](200) NOT NULL,
      [ItemName] [varchar](200) NULL,
      [QOH] [int] NULL,
      [Price] [decimal](19, 4) NULL,
      [Discontinued] [bit] NULL,
      [Barcode] [varchar](25) NULL,
      [Integer2] [int] NULL,
      [Integer3] [int] NULL,
      [SalePrice] [decimal](19, 4) NULL,
      [SaleOn] [bit] NULL,
      [Price2] [decimal](19, 4) NULL
   )
   GO

如何在表值参数中转换数据类型？例子将不胜感激.

Answer 1

使用unsignedInt数据类型.

int range - 4 bytes, -2,147,483,648 to +2,147,483,647 
unsignedInt range - 0 to 4,294,967,295 

条形码值3001822585超过最大值2,147,483,647,因此抛出错误

编辑

unigned int在SQL Server中找不到,但MySQL支持它.对于SQL Server,您必须使用bigINT

bigInt range - 8 bytes -2^63 to 2^63-1 

所以将Barcode列的数据类型更改为bigInt .如果您认为其他列值可能超出int范围,那么也要更改其数据类型.
