When I tried to dump database using command line, it gave me following error.
Command:
D:\TOOLS\MySQL\MySQL Server 5.6\bin>mysqldump -u root -p webchat > tut_backup.sql
Error:
mysqldump: unknown option '--no-beep'
Add host-name in your command, like:
D:\TOOLS\MySQL\MySQL Server 5.6\bin>mysqldump -h localhost -u root -p webchat > tut_backup.sql
Replace localhost with your host-name if it is different.
I consider webchat is your database name and you will have to type password explicitly after firing this command.
And of course you have to remove --no-beep (as suggested by Mark Setchell ) from mysql configuration file.
Hope it helps, thanks.

I'm a web development student and struggling to solve this problem on my own, any help would be appreciated!
Note that I'm working in an Amazon Cloud9 instance. My problem is that when I try to import an SQL file into a PostgreSQL database using the following command:
$ psql -d my_database < file_to_import.sql
I get the following error:
https:/raw.githubusercontent.com/...[removed for privacy]: No such file or directory
I know the file exists, because I'm able to navigate to it. I've tried copying the contents of the file into a new file on my desktop and then inserting the path to that file in the place of "file_to_import.sql" but that's not working either. I get the same error.
I've also tried importing via this template:
my_database=# \i ~/some/files/file_to_import.sql
But I get the same error. What's gone wrong here?
Thanks in advance!
These issues can be occurred because lack of permissions for a file try one of the following commands with the proper elevated permissions. For number one, you don't need sudo but if that didn't work try the second one of them should help you
1. psql -h hostname -d databasename -U username -f file.sql
2. sudo -u postgres psql db_name < 'file_path'
I have some .sql files with thousands of INSERT statements in them and need to run these inserts on my PostgreSQL database in order to add them to a table. The files are that large that it is impossible to open them and copy the INSERT statements into an editor window and run them there. I found on the Internet that you can use the following by navigating to the bin folder of your PostgreSQL install:
psql -d myDataBase -a -f myInsertFile
In my case:
psql -d HIGHWAYS -a -f CLUSTER_1000M.sql
I am then asked for a password for my user, but I cannot enter anything and when I hit enter I get this error:
psql: FATAL: password authentication failed for user "myUsername"
Why won't it let me enter a password. Is there a way round this as it is critical that I can run these scripts?
I got around this issue by adding a new entry in my pg_hba.conf file with the following structure:
# IPv6 local connections:
host myDbName myUserName ::1/128 trust
The pg_hba.conf file can usually be found in the 'data' folder of your PostgreSQL install.
Of course, you will get a fatal error for authenticating, because you do not include a user name...
Try this one, it is OK for me :)
psql -U username -d myDataBase -a -f myInsertFile
If the database is remote, use the same command with host
psql -h host -U username -d myDataBase -a -f myInsertFile
You should do it like this:
\i path_to_sql_file
See:
You have four choices to supply a password:
Set the PGPASSWORD environment variable. For details see the manual: http://www.postgresql.org/docs/current/static/libpq-envars.html
Use a .pgpass file to store the password. For details see the manual: http://www.postgresql.org/docs/current/static/libpq-pgpass.html
Use "trust authentication" for that specific user: http://www.postgresql.org/docs/current/static/auth-methods.html#AUTH-TRUST
Since PostgreSQL 9.1 you can also use a connection string: https://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING
Use this to execute *.sql files when the PostgreSQL server is located in a difference place:
psql -h localhost -d userstoreis -U admin -p 5432 -a -q -f /home/jobs/Desktop/resources/postgresql.sql
-h PostgreSQL server IP address
-d database name
-U user name
-p port which PostgreSQL server is listening on
-f path to SQL script
-a all echo
-q quiet
Then you are prompted to enter the password of the user.
EDIT: updated based on the comment provided by #zwacky
If you are logged in into psql on the Linux shell the command is:
\i fileName.sql
for an absolute path and
\ir filename.sql
for the relative path from where you have called psql.
export PGPASSWORD=<password>
psql -h <host> -d <database> -U <user_name> -p <port> -a -w -f <file>.sql
Via the terminal log on to your database and try this:
database-# >#pathof_mysqlfile.sql
or
database-#>-i pathof_mysqlfile.sql
or
database-#>-c pathof_mysqlfile.sql
You can give both user name and PASSSWORD on the command line itself with the "-d" parameter
psql -d "dbname='urDbName' user='yourUserName' password='yourPasswd' host='yourHost'" -f yourFileName.sql
you could even do it in this way:
sudo -u postgres psql -d myDataBase -a -f myInsertFile
If you have sudo access on machine and it's not recommended for production scripts just for test on your own machine it's the easiest way.

if your PostgreSQL database is on your system locally.
psql dbname < sqldump.sql username
If its hosted online
psql -h hostname dbname < sqldump.sql username

Walk through on how to run an SQL on the command line for PostgreSQL in Linux:
Open a terminal and make sure you can run the psql command:
psql --version
which psql
Mine is version 9.1.6 located in /bin/psql.
Create a plain textfile called mysqlfile.sql
Edit that file, put a single line in there:
select * from mytable;
Run this command on commandline (substituting your username and the name of your database for pgadmin and kurz_prod):
psql -U pgadmin -d kurz_prod -a -f mysqlfile.sql

Can someone help me? The solutions I have found don't work.
A detailed description please.
On Windows 7.
pg_dump defaults to plain SQL export. both data and structure.
open command prompt and
run pg_dump -U username -h localhost databasename >> sqlfile.sql
Above command is preferable as most of the times there will be an error which will be something like - ...FATAL: Peer authentication failed for user ...
In windows, first, make sure the path is added in environment variables PATH
C:\Program Files\PostgreSQL\12\bin
After a successful path adding restart cmd and type command
pg_dump -U username -p portnumber -d dbname -W -f location
this command will export both schema and data
for only schema use -s in place of -W
and for only data use -a.
replace each variable like username, portnumber, dbname and location according to your situation
everything is case sensitive, make sure you insert everything correctly,
and to import
psql -h hostname -p port_number -U username -f your_file.sql databasename
make sure your db is created or creation query is present in .sql file
Documentation: https://www.postgresql.org/docs/current/app-pgdump.html
Go to your command line and run
pg_dump -U userName -h localhost -d databaseName > ~/Desktop/cmsdump.sql

I am trying to backup my database and keep getting error :
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '$ mysqldump -u root -p chandlers > backup_db.sql' at line 1
I am using the following command to launch the backup :
$ mysqldump -h localhost -u root -p chandlers > backup_db.sql
edit>>>>
This is how I connect to the db, this is a shortcut I have setup to open a command line :
C:\server2go\server2go\server\mysql\bin\mysql.exe -h localhost -P 7188 -u root
This works fine and connects, I have tried creating another like this >>
C:\server2go\server2go\server\mysql\bin\mysqldump.exe $ mysqldump -h localhost -P 7188 -u root -pchandlers > backup_db.sql
but I am getting an access denied error now.
you can use mysqldump to backup mysql database.
Below is the script example to backup mysql database in command line:-
$ mysqldump -h localhost -u username -p database_name > backup_db.sql
If your mysql database is very big, you might want to compress your sql file.
Just use the mysql backup command below and pipe the output to gzip,
then you will get the output as gzip file.
$ mysqldump -u username -h localhost -p database_name | gzip -9 > backup_db.sql.gz
If you want to extract the .gz file, use the command below:-
$ gunzip backup_db.sql.gz
You seem to be calling mysqldump from within mySQL, which is incorrect - it's a separate executable.
Call it from the command line instead.
I think it should be $ mysqldump -h localhost -u root -pchandlers > backup_db.sql. Otherwise it seems fine to me.
