I try this:
COPY gemeenten
FROM 'D:\CBS_woningcijfers_2014.csv'
DELIMITER ';' CSV
and get this:
ERROR: could not open file "D:\CBS_woningcijfers_2014.csv" for reading: No such file or directory
I doubled the backslashes, tried an E string, replaced \ by /, used " instead of ' but now I've run out of options. I am sure the file exists. Anybody any idea?
If the file and the PostgreSQL database are on the same machine, then the path and/or name of the file are not correct.
If the file is on your local machine and the database is on another, you cannot use the COPY command in SQL. You have two main choices to make this work:
1) Use psql \copy from your local machine. The syntax is similar, but it will transfer from your local to the remote. The docs are pretty helpful: https://www.postgresql.org/docs/9.5/static/app-psql.html#APP-PSQL-META-COMMANDS-COPY
2) Upload the file to the remote machine and then execute your command. Just make sure you are referencing the correct path and filename.

when running:
~/fidelity/releases/20220907033831$ ls -a
.
..
.browserslistrc
221005_users_all.csv
_private
the presence of a file is confirmed.
However, when launching a postgresql command
psql fidelity_development
COPY users (id,migrated_id,[...]) FROM '~/fidelity/releases/20220907033831/221005_users_all.csv' DELIMITER ';' CSV HEADER;
The response is unexpected:
ERROR: could not open file "~/fidelity/releases/20220907033831/221005_users_all.csv" for reading: No such file or directory
What am I missing to determine why postgresql cannot see this file?
note this directory was also simlinked as fidelity/current and the same result was obtained when referring to that directory for the file, whereas bash sees it.
Use \COPY command as this one is client based and handles the local path correctly.
While COPY is server based and this could cause issues finding your file.
I am trying to copy a file from my Office Remote server as CSV output on my local machine (windows). I cannot use the export/import dialog. It shows the following error
Utility file not found. Please correct the Binary Path in the Preferences dialog
The same command works fine for local server files meaning I have already edited the binary path in the Configuration setting.
The COPY command gives the following error
ERROR: relative path not allowed for COPY to file SQL state: 42602
\Copy doesn't work either.
Can anyone suggest me a solution for this?
Good afternoon,
You can generate the CSV file like this:
copy(select * from schema.table) TO '/tmp/file.csv' WITH CSV DELIMITER '|';
I am trying to import a CSV file into postgresSQL, however, I keep getting the error that no such file exists or directory.
this is the line of code I execute copy mu_data from
copy mu_data from 'users/mysurname/Desktop/FILE.CSV' DELIMITER ',' CSV
HEADER;
Can anyone suggest how to fix this?
copy is a command run on the server side. So unless your Postgres server happens to be on your localhost, the file very likely doesn't exist from the view of the server.
So one solution is you to transfer the file to the servers filesystem somehow. Or, if you're using the psql command line tool (or at least can use it for this task), you can use the \copy command there.
I'm trying to import a (rather large) .txt file into a table geonames in PostgreSQL 9.1. I'm in the /~ directory of my server, with a file named US.txt placed in that directory. I set the search_path variable to geochat, the name of the database I'm working in. I then enter this query:
COPY geonames
FROM 'US.txt',
DELIMITER E'\t',
NULL 'NULL');
I then receive this error:
ERROR: could not open file "US.txt" for reading: No such file or directory.
Do I have to type in \i US.txt or something similar first, or should it just get it from the present working directory?
Maybe a bit late, but hopefully useful:
Use \copy instead

A couple of misconceptions:
1.
I'm in the /~ directory of my server
There is no directory /~. It's either / (root directory) or ~ (home directory of current user). It's also irrelevant to the problem.
2.
I set the search_path variable to geochat, the name of the database I'm working in
The search_path has nothing to do with the name of the database. It's for schemas inside the current database. You probably need to reset this.
3.
You are required to use the absolute path for your file. As documented in the manual here:
filename
The absolute path name of the input or output file.
4.
DELIMITER: just noise.
The default is a tab character in text format
5.
NULL: It's rather uncommon to use the actual string 'NULL' for a NULL value. Are you sure?
The default is \N (backslash-N) in text format, and an unquoted empty string in CSV format.
My guess (after resetting search_path - or you schema-qualify the table name):
COPY geonames FROM '/path/to/file/US.txt';
The paths are relative to the PostgreSQL server, not the psql client.
Assuming you are running PostgreSQL 9.4, you can put US.txt in the directory /var/lib/postgresql/9.4/main/.
Another option is to pipe it in from stdin:
cat US.txt | psql -c "copy geonames from STDIN WITH (FORMAT csv);"
if you're running your COPY command from a script, you can have a step in the script that creates the COPY command with the correct absolute path.
MYPWD=$(pwd)
echo "COPY geonames FROM '$MYPWD/US.txt', DELIMITER E'\t';"
MYPWD=
you can then run this portion into a file and execute it
./step_to_create_COPY_with_abs_path.sh >COPY_abs_path.sql
psql -f COPY_abs_path.sql -d your_db_name
I'm trying to import a csv file using the COPY FROM command with postgres.
The db is stored on a linux server, and my data is stored locally, i.e. C:\test.csv
I keep getting the error:
ERROR: could not open file "C:\test.csv" for reading: No such file or directory
SQL state: 58P01
I know that I need to use the absolute path for the filename that the server can see, but everything I try brings up the same error
Can anyone help please?
Thanks
Quote from the PostgreSQL manual:
The file must be accessible to the server and the name must be specified from the viewpoint of the server
So you need to copy the file to the server before you can use COPY FROM.
If you don't have access to the server, you can use psql's \copy command which is very similar to COPY FROM but works with local files. See the manual for details.
