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 data from a CSV file into PostgreSQL using pgAdmin. However, I am getting an error message when attempting to perform a COPY command.
ERROR: could not open file "/Users/brandoncruz/Desktop/Test File.csv" for reading: Permission denied
HINT: COPY FROM instructs the PostgreSQL server process to read a file. You may want a client-side facility such as psql's \copy.
SQL state: 42501
Below is the code I have attempted to use for the import.
CREATE TABLE roles(
role_id serial PRIMARY KEY,
role_name VARCHAR (255)
);
COPY roles FROM '/Users/brandoncruz/Desktop/Test File.csv' DELIMITER ',' CSV HEADER;
It looks about your permissions. You can change permissions of 'Test File.csv'. I mean Postgres user cannot read your file. After change permissions it must be copied successfully.
You might need to check following path if you are using pgAdmin:
pgAdmin > File > Preferences
Paths > Binary Paths
For postgreSQL binary path, you should find the location of PostgreSQL from your mac and save that:
i.e. C:\Program Files\PostgreSQL\12\bin (Windows)
For mac, check under Applications, Program Files, that depends and changes from Mac to Mac.
Computer: Mac OS X, version 10.8
Database: Postgres
Trying to import csv file into postgres.
pg> copy items_ordered from '/users/darchcruise/desktop/items_ordered.csv' with CSV;
ERROR: could not open file "/users/darchcruise/desktop/items_ordered.csv" for reading: Permission denied
Then I tried
$> chown postgres /users/darchcruise/desktop/items_ordered.csv
chown: /users/darchcruise/desktop/items_ordered.csv: Operation not permitted
Lastly, I tried
$> ls -l
-rw-r--r-- 1 darchcruise staff 1016 Oct 18 21:04 items_ordered.csv
Any help is much appreciated!
Assuming the psql command-line tool, you may use \copy instead of copy.
\copy opens the file and feeds the contents to the server, whereas copy tells the server the open the file itself and read it, which may be problematic permission-wise, or even impossible if client and server run on different machines with no file sharing in-between.
Under the hood, \copy is implemented as COPY FROM stdin and accepts the same options than the server-side COPY.
Copy the CSV file to /tmp
For me this solved the issue.
chmod a+rX /users/darchcruise/ /users/darchcruise/desktop /users/darchcruise/desktop/items_ordered.csv
This will change access rights for your folder. Note that everyone will be able to read your file.
You can't use chown being a user without administrative rights.
Also consider learning umask to ease creation of shared files.
Copy your CSV file into the /tmp folder
Files named in a COPY command are read or written directly by the server, not by the client application. Therefore, they must reside on or be accessible to the database server machine, not the client. They must be accessible to and readable or writable by the PostgreSQL user (the user ID the server runs as), not the client. COPY naming a file is only allowed to database superusers, since it allows reading or writing any file that the server has privileges to access.
I had the issue when I was trying to export data from a remote server into the local disk. I hadn't realised that SQL copy actually is executed on the server and that it tries to write to a server folder. Instead the correct thing to do was to use \copy which is the psql command and it writes to the local file system as I expected. http://www.postgresql.org/message-id/CAFjNrYsE4Za_KWzmfgN1_-MG7GTw_vpMRxPk=OEjAiLqLskxdA#mail.gmail.com
Perhaps that might be useful to someone else too.
Another way to do this, if you have pgAdmin and are comfortable using the GUI is to go the table in the schema and right click on the table you wish to import the file to and select "Import" browse your computer for the file, select the type your file is, the columns you want the data to be imputed into, and then select import.
That was done using pgAdmin III and the 9.4 version of PostgreSQL
I resolved the same issue with a recursive chown on the parent folder:
sudo chown -R postgres:postgres /home/my_user/export_folder
(my export being in /home/my_user/export_folder/export_1.csv)
for macbook first i opened terminal then type
open /tmp
or in finder directory you directly enter command+shift+g then type /tmp in go to the folder.
it opens temp folder in finder. then i paste copied csv file into this folder.then again i go to postgres terminal and typed below command and then it is copied my csv data into db table
\copy recharge_operator FROM '/private/tmp/operator.csv' DELIMITER ',' CSV;
COPY your table (Name, Latitude, Longitude) FROM 'C:\Temp\your file.csv' DELIMITERS ',' CSV HEADER;
Use c:\Temp\"Your File"\.
For me it worked to simply to add sudo (or run as root) for the chown command:
sudo chown postgres /users/darchcruise/desktop/items_ordered.csv
You must grant the pg_read_server_files permission to the user if you are not using postgres superuser.
Example:
GRANT pg_read_server_files TO my_user WITH ADMIN OPTION;
just in case you're facing this problem under windows 10 , add the group of users "youcomputer\Users" on the security Tab and grant it full control , that solved my issue
I had the same error message but was using psycopg2 to communicate with PostgreSQL. I fixed the permission issues by using the functions copy_from and copy_expert that will open the file on the client side as the user running the python script and feed the data to the database over STDIN.
Refer to this link for further information.
This answer is only for Linux Beginners.
Assuming initially the DB user didn't have file/folder(directory) permission on the client side.
Let's constrain ourselves to the following:
User: postgres
Purpose: You wanted to (write to / read from) a specific folder
Tool: psql
Connected to a specific database: YES
FILE_PATH: /home/user/training/sql/csv_example.csv
Query: \copy (SELECT * FROM table_name TO FILE_PATH, DELIMITER ',' CSV HEADER;
Actual Results: After running the query you got an error : Permission Denied
Expected Results: COPY COUNT_OF_ROWS_COPIED
Here are the steps I'd follow to try and resolve it.
Confirm the FILE_PATH permissions on your File system.
Inside a terminal to view the permissions for a file/folder you need to long list them by entering the command ls -l.
The output has a section that shows sth like this -> drwxrwxr-x
Which is interpreted in the following way:
TYPE | OWNER RIGHTS | GROUP RIGHTS | USER RIGHTS
rwx (r: Read, W: Write, X: Execute)
TYPE (1 Char) = d: directory, -: file
OWNER RIGHTS (3 Chars after TYPE)
GROUP RIGHTS (3 Chars after OWNER)
USER RIGHTS (3 Chars after GROUP)
If permissions are not enough (Ensure that a user can at least enter all folders in the path you wanted path) - x.
This means for FILE_PATH, All the directories (home , user, training, sql) should have at least an x in the USER RIGHTS.
Change permissions for all parent folders that you need to enter to have a x. You can use chmod rights_you_want parent_folder
Assuming /training/ didn't have an execute permission.
I'd go the user folder and enter chmod a+x training
Change the destination folder/directory to have a w if you want to write to it. or at least a r if you want to read from it
Assuming /sql didn't have a write permission.
I would now chmod a+w sql
Restart the postgresql server sudo systemctl restart postgresql
Try again.
This would most probably help you now get a successful expected result.
On Linux you can fix this by giving the postgres user read/write/execute permissions on the target directory. Eg:
setfacl -m u:postgres:rwx /home/hi
I just copied the source csv file to another folder in which you have more permissions (C:/temp), and it worked fine.
May be You are using pgadmin by connecting remote host then U are trying to update there from your system but it searches for that file in remote system's file system... its the error wat I faced May be its also for u check it
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.
