错误：COPY分隔符必须是一个单字节字符 [英] ERROR: COPY delimiter must be a single one-byte character

问题描述

我想将数据从带有分隔符〜，〜的平面文件加载到PostgreSQL表中。我尝试了如下操作，但看起来分隔符有限制。如果COPY语句不允许使用多个字符作为分隔符，

I want to load the data from a flat file with delimiter "~,~" into a PostgreSQL table. I have tried it as below but looks like there is a restriction for the delimiter. If COPY statement doesn't allow multiple chars for delimiter, is there any alternative to do this?

metadb=# \COPY public.CME_DATA_STAGE_TRANS FROM 'E:\Infor\Outbound_Marketing\7.2.1\EM\metadata\pgtrans.log' WITH      DELIMITER AS '~,~'
ERROR:  COPY delimiter must be a single one-byte character
\copy: ERROR:  COPY delimiter must be a single one-byte character

推荐答案

如果您使用的是 Vertica ，您可以使用E'\t'或U&'\0009'

If you are using Vertica, you could use E'\t'or U&'\0009'

要指示非打印定界符（例如制表符），
以扩展字符串语法（E'...'）指定字符。如果您的
数据库启用了StandardConformingStrings，请使用Unicode字符串
文字（U& ...）。例如，在
中使用E’ampt或U&’000000来指定制表符作为分隔符。

To indicate a non-printing delimiter character (such as a tab), specify the character in extended string syntax (E'...'). If your database has StandardConformingStrings enabled, use a Unicode string literal (U&'...'). For example, use either E'\t' or U&'\0009' to specify tab as the delimiter.
