BCP错误:仅当复制到服务器时，才可以跳过列 [英] BCP Error: columns may be skipped only when copying into the Server

问题描述

当我发出此命令时(它看起来很傻，但是可以正常工作):

When I issue this command (It looks silly but it works):

BCP "declare @colnames varchar(max); select @colnames=coalesce (@colnames+char(9), '') 
+ Column_Name from db.information_Schema.columns where table_name='table1' order by 
ordinal_position; select @colnames" 
     queryout Table1_Columns.tsv -S?? -U?? -P?? -f** -e**

我收到此错误:

[Microsoft] [SQL Native Client]仅在以下情况下可以跳过主机文件列 复制到服务器

[Microsoft][SQL Native Client]Host-file columns may be skipped only when copying into the Server

格式文件为:

9.0
1
1 SQLCHAR 0 100 "\r\n" 1 Column_Names SQL_Latin1_General_CP1_CI_AS

有人可以告诉我为什么出现此错误吗?

Can someone tell me why I am getting this error?

推荐答案

对此有一个有效的错误报告:

There's an active bug report for this: http://connect.microsoft.com/SQLServer/feedback/details/584001/bcp-table-out-with-format-file-does-not-work-if-file-specifies-less-columns-than-source-table.

一种简单的解决方法是将变量写入临时表(不是#temptable，而是临时表)，然后从该表中删除bcp.

One simple workaround would be to write the variable to a temporary table (not a #temptable, but rather a table that is temporary), and bcp out from that.
