我愿利用邮政总局的《公约》缔约方会议职能,将CSV档案输入邮政局的数据库。
如在 rel=“nofollow”>documentation上说,CSV档案必须存放在一个特定地点,或者可以存放在任何地点。
例如,copy data_table from /tmp/outputdata.csv CSV QUOTE AS“;。 凡是说<条码>tmp,就是指C类:驱动器。 能否改用另一个字眼?
看起来,就像你一样,也受到Liberin vs的混淆。 Windows file-path notation. 你们有一条通往根基的含水层。 视窗使用驱动信,在您在视窗上运行时,你可以说明。

COPY data_table from E C:\tmp\outputdata.csv WITH ...
With standard_conforming_strings = on you can simply write:
COPY data_table from C: mpoutputdata.csv WITH ...
Note that a PostgreSQL Windows server also understands default path notation with slashes instead of backslashes.
COPY from / to 您可使用服务器程序所有人(postgres)允许读/写的任何途径。
copy metator of the psql的客户,申请当地现有用户的许可。

只注意在窗户上,你不得不以这种方式逃避冲锋:
copy data_table from c:\Temp\outputdata.csv WITH DELIMITER AS , CSV QUOTE AS " ;
