如何使用 pgAdmin 将 CSV 文件导入 PostgreSQL 表

Question

I am trying to import the following csv file (named dummy.csv):

"F1", "F2", "F3"

1,2,"a"

3,4, "b"

3.4,2.4,"c"

to PostgreSQL using the pgAdmin GUI with the following command:

"C:\\Program Files\\PostgreSQL\\12\\bin\\psql.exe" 
--command " "\\copy public.\"Result\" 
FROM 'dummy.csv' 
DELIMITER ',' 
CSV HEADER ENCODING 'UTF8' 
QUOTE '\"' 
ESCAPE '''';""

but keep getting the following error :

ERROR: extra data after the last expected column
CONTEXT:  COPY Result, line 2: «1,2,"a" 

What am I doing wrong?

Answer 1

The csv is not very 'clean':

"F1", "F2", "F3"

1,2,"a"

3,4, "b"

3.4,2.4,"c"

There are spaces between the separator and the quotes which could give problems with some parsers.

Maybe try with the following first and see what this gives:

"F1","F2","F3"
1,2,"a"
3,4,"b"
3.4,2.4,"c"

You could even remove the quotes in this example.
