在Acumatica ERP中，我在导入订单时得到了相同的错误。

字符串或二进制数据将被截断在表'MyDatabase.dbo。ARInvoice'，列'InvoiceNbr'。截断值“Something”。

在做了这个链接中描述的步骤如何修复字符串或二进制截断错误后，我得到了另一个错误“数量将变成负数”，这是通过在收据屏幕中创建一些数量来解决的。

您需要发布源表和目标表的表定义，以便我们找出问题所在，但底线是源表中的一列比目标列大。这可能是您正在以一种您没有意识到的方式更改格式。要弄清楚这一点，您要使用的数据库模型也很重要。

这可能是一个具有挑战性的错误。以下是AmirCharania在https://connect.microsoft.com/SQLServer/feedback/details/339410/网站上发表的评论。

我调整了AmirCharania给出的答案，用于选择实际表中的数据，而不是临时表。首先选择你的数据集到一个开发表中，然后运行以下命令:

WITH CTE_Dev
AS (
    SELECT C.column_id
        ,ColumnName = C.NAME
        ,C.max_length
        ,C.user_type_id
        ,C.precision
        ,C.scale
        ,DataTypeName = T.NAME
    FROM sys.columns C
    INNER JOIN sys.types T ON T.user_type_id = C.user_type_id
    WHERE OBJECT_ID = OBJECT_ID('YOUR TARGET TABLE NAME HERE, WITH SCHEMA')
    )
    ,CTE_Temp
AS (
    SELECT C.column_id
        ,ColumnName = C.NAME
        ,C.max_length
        ,C.user_type_id
        ,C.precision
        ,C.scale
        ,DataTypeName = T.NAME
    FROM sys.columns C
    INNER JOIN sys.types T ON T.user_type_id = C.user_type_id
    WHERE OBJECT_ID = OBJECT_ID('YOUR TEMP TABLE NAME HERE, WITH SCHEMA')
    )
SELECT *
FROM CTE_Dev D
FULL OUTER JOIN CTE_Temp T ON D.ColumnName = T.ColumnName
WHERE ISNULL(D.max_length, 0) < ISNULL(T.max_length, 999)

是的，我也面临着这样的问题。

REMARKS VARCHAR(500)
to
REMARKS VARCHAR(1000)

在这里，我将备注文件的长度从500更改为1000

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)        |
                    +---------------------------+-----------------------+

                    +---------------------------+-----------------------+

                    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.

SQL Server 2019将最终返回更有意义的错误消息。

二进制或字符串数据将被截断=>错误消息增强 如果您(在生产环境中)出现了该错误，则不太容易看到该错误来自哪一列或哪一行，以及如何准确定位它。

要启用新行为，需要使用DBCC TRACEON(460)。sys.messages中的新错误文本:

SELECT * FROM sys.messages WHERE message_id = 2628

2628 -字符串或二进制数据将在表' %中被截断。*ls '，列' %.*ls '。截断值:' %.*ls '。

字符串或二进制数据将被截断:替换臭名昭著的错误8152

这个新消息也会被反向移植到SQL Server 2017 CU12(以及即将发布的SQL Server 2016 SP2 CU)，但不是默认情况下。您需要启用跟踪标志460，以便在会话级别或服务器级别将消息ID 8152替换为2628。 请注意，目前即使在SQL Server 2019 CTP 2.0中也需要启用相同的跟踪标志460。在未来的SQL Server 2019版本中，默认情况下，消息2628将取代消息8152。

SQL Server 2017 CU12也支持该特性。

改进:在SQL Server 2017中用扩展信息替换“字符串或二进制数据将被截断”消息

此SQL Server 2017更新引入了一条可选消息，其中包含以下附加上下文信息。 Msg 2628，级别16，状态6，程序程序命名，行Linenumber 字符串或二进制数据将在表'%中被截断。*ls'，列'%.*ls'。 截断值:'%.*ls'。 新的消息ID是2628。如果启用了跟踪标志460，此消息将替换任何错误输出中的消息8152。

ALTER DATABASE SCOPED CONFIGURATION VERBOSE_TRUNCATION_WARNINGS = { ON | OFF } APPLIES TO: SQL Server (Starting with SQL Server 2019 (15.x)) and Azure SQL Database Allows you to enable or disable the new String or binary data would be truncated error message. SQL Server 2019 (15.x) introduces a new, more specific error message (2628) for this scenario: String or binary data would be truncated in table '%.*ls', column'%.*ls'. Truncated value: '%.*ls'. When set to ON under database compatibility level 150, truncation errors raise the new error message 2628 to provide more context and simplify the troubleshooting process. When set to OFF under database compatibility level 150, truncation errors raise the previous error message 8152. For database compatibility level 140 or lower, error message 2628 remains an opt-in error message that requires trace flag 460 to be enabled, and this database scoped configuration has no effect.
