我参与了一个数据迁移项目。当我试图将数据从一个表插入到另一个表(SQL Server 2005)时，我得到以下错误:
编号8152,16层，状态13,1线 字符串或二进制数据将被截断。
源数据列与数据类型匹配，并且在目标表列的长度定义内，因此我不知道是什么原因导致了这个错误。
当前回答
请尝试以下代码:
CREATE TABLE [dbo].[Department](
[Department_name] char(10) NULL
)
INSERT INTO [dbo].[Department]([Department_name]) VALUES ('Family Medicine')
--error will occur
ALTER TABLE [Department] ALTER COLUMN [Department_name] char(50)
INSERT INTO [dbo].[Department]([Department_name]) VALUES ('Family Medicine')
select * from [Department]
其他回答
面对同样的问题。
日志含义源表中的列长度大于目标表中的列长度 源列长度- 50和 目标列长度- nvarchar(25)，并将其增加到nvarchar(50)，并且它工作
是的，“一品脱的酒放进半品脱的锅里是不行的”。我对人们建议的各种sp没有太多的运气(无论出于什么原因)，但只要两个表在同一个DB中(或者您可以将它们放到同一个DB中)，您就可以使用INFORMATION_SCHEMA。列来定位错误字段，因此:
select c1.table_name,c1.COLUMN_NAME,c1.DATA_TYPE,c1.CHARACTER_MAXIMUM_LENGTH,c2.table_name,c2.COLUMN_NAME, c2.DATA_TYPE,c2.CHARACTER_MAXIMUM_LENGTH
from [INFORMATION_SCHEMA].[COLUMNS] c1
left join [INFORMATION_SCHEMA].[COLUMNS] c2 on
c1.COLUMN_NAME=c2.COLUMN_NAME
where c1.TABLE_NAME='MyTable1'
and c2.TABLE_NAME='MyTable2'
--and c1.DATA_TYPE<>c2.DATA_TYPE
--and c1.CHARACTER_MAXIMUM_LENGTH <> c2.CHARACTER_MAXIMUM_LENGTH
order by c1.COLUMN_NAME
这将允许您上下滚动，比较字段的长度。注释的部分可以让您查看(显然是在未注释的情况下)是否存在数据类型不匹配，或者特别显示字段长度不同的数据类型(因为我懒得滚动)，只需注意，所有内容都基于与目标列名匹配的源列名。
我构建了一个存储过程，它分析一个源表或查询，每个列都有几个特征，其中最小长度(min_len)和最大长度(max_len)。

我写了一个有用的存储过程来帮助识别和解决使用INSERT SELECT语句时的文本截断问题(字符串或二进制数据将被截断)。它只比较字段CHAR, VARCHAR, NCHAR和NVARCHAR，并在可能导致错误的情况下逐字段返回一个评估字段。
EXEC dbo.GetFieldStringTruncate SourceTableName, TargetTableName
这个存储过程针对的是在执行INSERT SELECT语句时的文本截断问题。 此存储过程的操作取决于用户之前是否识别出有问题的INSERT语句。然后将源数据插入到全局临时表中。建议使用SELECT INTO语句。 必须在SELECT语句的每个字段的别名中使用目标表字段的相同名称。
函数代码:
DECLARE @strSQL nvarchar(1000)
IF NOT EXISTS (SELECT * FROM dbo.sysobjects where id = OBJECT_ID(N'[dbo].[GetFieldStringTruncate]'))
BEGIN
SET @strSQL = 'CREATE PROCEDURE [dbo].[GetFieldStringTruncate] AS RETURN'
EXEC sys.sp_executesql @strSQL
END

Description:
Syntax
---------------
dbo.GetFieldStringTruncate(SourceTable, TargetTable)
+---------------------------+-----------------------+
| SourceTableName | VARCHAR(255) |
+---------------------------+-----------------------+
| TargetTableName | VARCHAR(255) |
+---------------------------+-----------------------+
Arguments
---------------
SourceTableName
The name of the source table. It should be a temporary table using double charp '##'. E.g. '##temp'
TargetTableName
The name of the target table. It is the table that receives the data used in the INSERT INTO stament.
Return Type
----------------
Returns a table with a list of all the fields with the type defined as text and performs an evaluation indicating which field would present the problem of string truncation.
Remarks
----------------
This stored procedure is oriented to the problem of text truncation when an INSERT SELECT statement is made.
The operation of this stored procedure depends on the user previously identifying the INSERT statement with the problem. Then inserting the source data into a global temporary table. The SELECT INTO statement is recommended.
You must use the same name of the field of the destination table in the alias of each field of the SELECT statement.
Examples
====================================================================================================
--A. Test basic
IF EXISTS (SELECT * FROM sys.objects WHERE OBJECT_ID = OBJECT_ID(N'[dbo].[tblDestino]') AND TYPE IN (N'U'))
DROP TABLE tblDestino

'123456789' , -- Field11 - varchar(50)
'123456789' -- Field12 - varchar(50)
GO
Result:
String or binary data would be truncated
*Here you get the truncation error. Then, we proceed to save the information in a global temporary table.
*IMPORTANT REMINDER: You must use the same name of the field of the destination table in the alias of each field of the SELECT statement.

我将添加另一个可能导致这个错误的原因，因为没有人提到过它，它可能会帮助一些未来的人(因为OP已经找到了他的答案)。如果要插入的表有触发器，则可能是触发器正在生成错误。我曾在更改表字段定义时看到过这种情况，但审计表没有更改。
