将CSV文件复制到具有选定列的SQL表

Question

我有这样的CSV

#+BEGIN_SRC shell :results output
cat data/supervisor_salaries.csv
#+END_SRC

#+RESULTS:
town,supervisor,salary
Anytown,Jones,27000
Bumblyburg,Baker,24999
Moetown,Smith,32100
Bigville,Kao,31500
New Brillig,Carroll,72690

试图将其写入表

#+begin_src sql :engine postgresql :dbuser org  :dbpassword 1618 :database analysis
\copy supervisor_salaries (town, supervisor, salary) FROM 'data/supervisor_salaries.csv'
WITH (FORMAT CSV, HEADER);
#+end_src

但报告错误：

psql:/tmp/babel-PSl3Td/sql-in-rlHtPW:1: ERROR:  missing data for column "supervisor"
CONTEXT:  COPY supervisor_salaries, line 1: "town,supervisor,salary"

错误“缺少列'supervisor'的数据，但csv文件中确实有超级用户列，这是什么问题？

Answer 1

\copy命令是Postgres终端工具psql的特定功能，它不是SQL语句。所有psql命令（以\开头）都必须放在一行中，因此您已经执行了

\copy supervisor_salaries (town, supervisor, salary) FROM 'data/supervisor_salaries.csv'

由于错误定义了文件格式（默认为text）而引发错误。
