截断错误从Excel导入SQL Server 2005 [英] Truncation errors importing to SQL Server 2005 from Excel

问题描述

长篇小说，我一个接一个地使用一组excel文档，并使用导入/导出向导将它们导入SQL Server 2005中的数据库。

Long story short, I'm taking a bunch of excel documents one by one, and importing them using the Import/Export wizard into a database in SQL Server 2005.

这是一个报告（所有进程未显示为成功）。有没有办法忽略截断错误？我已经googled了无济于事，或至少不在我的版本。

Here's one report (all processes not shown are a "Success"). Is there any way for me to ignore truncation errors? I've googled around to no avail, or at least not in my version.

- Executing (Success)

- Copying to [Datadev].[dbo].[Sheet0$] (Error)

推荐答案

向导使用较小的值作为Excel数据的标准varchar大小，而不是SQL Server 2000中向导中的varchar大小。因此，它通常会截断您尝试快速导入到临时表的数据。但是，当您执行该向导时，一个屏幕会询问您是否要编辑映射，并且可以修复这些字段的大小。或者您可以先创建表格，以创建一个具有所需大小的工作表（如果您是第一次查看数据，那么nvarchar（max）很好，并且不知道这些字段的大小），然后导入进去。使用Excel，我知道我也有SQL服务器的问题只使用几行来确定数据类型，然后插入失败的记录（例如像partnumber一样），因为它认为基于前几个记录它是一个整数，当它真的是字符串类型的数据。你也可能会遇到这样的问题，所以即使没有收到截断错误，也是一个很好的方法来检查映射。

The wizard uses a smaller value as the standard varchar size for Excel data than you got in the wizard in SQL Server 2000. As a result it often truncates data that you are trying to do a quick import to a staging table on. However, when you do the wizard, one screen will ask you if you want to edit mappings and you can fix the size of the fields there. Or you can usea create table stament first to create a work table with the sizes you want (nvarchar(max) is good if you are looking at the data for the first time and have no idea how big the fields will be) and then import into it. With Excel, I know I have also had issues with SQl Server using only a few rows to determine datatype and then the insert failing for records (say for something like partnumber) because it thought based on the first few records it was an integer when it was really a string type of data. You also could be having an issue like this, so it is a good idea to review the mappings anyway even if you don't get truncation errors.
