I am trying to run the following command using psql but the --file argument is ignored event tough I manage to connect to the database.
psql "postgresql://postgres:admin12345#localhost:5432/Phoenix" -f "tables/book.sql"
The output on the terminal is as the screenshot shows.
What am I missing here? Thanks in advance.
After googling and wasting hours on testing different SO answers, this worked for me:
psql -f "tables/book.sql" "postgresql://postgres:admin12345#localhost:5432/Phoenix"
It looks like the psql command requires that the command-line arguments appear before the connection string. That's a bit weird but it worked for me.
Also the quotes are optional. This also works:
psql -f tables/book.sql postgresql://postgres:admin12345#localhost:5432/Phoenix
I tried changing code page as indicated on the section "Notes for Windows Users" in the psql doc psql docmentation. The result is the warning does not show anymore but the command line args are still ignored if the connection string precedes them like as shown in the following logs:
C:\Users\Zack
λ cmd.exe /c chcp 1252
Active code page: 1252
C:\Users\Zack
λ psql postgresql://postgres:admin12345#localhost:5432/Phoenix -f "tables/book.sql"
psql: warning: extra command-line argument "tables/book.sql" ignored
psql (13.2)
Type "help" for help.
Phoenix=#
Theo only fix that works for me now is making the other args preced the connection string.
If someone knows more about why command-line args should precede the connection string, please provide more details.
I had to automate my postgre database backup. As instructed by my software vendor I am trying to use pg_dump.exe (see below) file to take a backup but that prompts me for password.
.\pg_dump.exe -h localhost -p 4432 -U postgres -v -b -F t -f "C:\Backup\Backup.tar" Repo
So googled and found that as per "https://www.postgresql.org/docs/9.6/libpq-pgpass.html" I can create a pgpass.conf file within 'C:\Users\User1\AppData\Roaming\postgresql\pgpass.conf" which I did.
Then I tried to pass data of pgpass.conf file to env variable before executing my pg_dump command. But it is not working. Still I am getting prompt to enter password. This is the content of pgpass.conf file: *:*:*:postgres:password
Below is the code I am trying in PowerShell,
$Env:PGPASSFILE="C:\Users\User1\AppData\Roaming\postgresql\pgpass.conf"
cd "C:\Program Files\Qlik\Sense\Repository\PostgreSQL\9.6\bin"
.\pg_dump.exe -h localhost -p 4432 -U postgres -v -b -F t -f "C:\Backup\Backup.tar" Repo
Why am I still being asked for password?
When I type following code $Env:AppData I get following response "C:\Users\User1\AppData\Roaming"
Everywhere there are guidance on how to use it in UNIX or command prompt but not in powershell. Any help is appreciated. Also if you could direct me how to secure this password file then it will be great.
With password prompt I cannot automate it with windows task scheduler.
I suspect you have a suitable solution, however, as a quick (and not secure) workaround via the command prompt, you can use the variable PGPASSWORD to hold the password then run the backup script.
A sample might be something like:
SET PGPASSWORD=password
cd "C:\Program Files\Qlik\Sense\Repository\PostgreSQL\9.6\bin" pg_dump.exe -h localhost -p 4432 -U postgres -b -F t -f "d:\qs_backup\QSR_backup.tar" QSR

I have yet to get the damned thing to work yet, but I did find this:
-w
--no-password Never issue a password prompt. If the server requires password authentication and a password is not available by other means
such as a .pgpass file, the connection attempt will fail. This option
can be useful in batch jobs and scripts where no user is present to
enter a password.
I don't see a -w parameter in your call to pg_dump
I used pg_hba file to allow connection "trust" this is riskier method but I had to get things done ASAP. Thank you for your time and effort
I have run into a problem with the psql command in my BASH script as I am trying to login to my local postgres database and submit a query. I am using the command in the following way:
psql -U postgres -d rebasoft_appauditor -c "SELECT * FROM katan_scripts"
However, I get the following error message.
psql: FATAL: Ident authentication failed for user "postgres"
This runs perfectly fine from the command line after I appended the following changes to /var/lib/pgsql/data/pg_hba.conf:
local all all trust
host all all 127.0.0.1/32 trust
Also, could this please be verified for correctness?
I find it rather strange that database authentication works fine on the command line but in a script it fails. Could anyone please help with this?
Note: I am using MAC OSX
It might possibly depend on your bash script.
Watch for the asterisk (*) not be replaced with the file names in your current directory. And possibly a semicolon or \g might help to actually send the SQL statement to the database server.
I am just getting started with shell scripts to save me typing in the same commands over and over. This command is used to copy a database over to a slave server as part of setting up MySQL database replication.
It works when typed into the command prompt directly:
mysqldump --host=192.168.1.1 –uUSER –pPASSWORD --opt database_name | mysql --host=192.168.1.2 –uUSER –pPASSWORD -C database_name
USER, PASSWORD and database_name all are replaced with their actual values in the real script.
When I type this command into a scripts.sh file, give it the execute permission, and then run it with ./scripts.sh I get:
'RROR1102 (42000): Incorrect database name 'database_name
mysqldump: Got errno 32 on write
What could be causing this error? Do I need to modify the command somehow when it is contained in a shell script?
The variable your database name is in has a CR at the end. You may need to run your script through dos2unix, or use one of the solutions on this site for stripping CRs from data if you're getting the database name from an external source.
How can I access the MySQL command line with XAMPP for Windows?
Your MySQL binaries should be somewhere under your XAMPP folder. Look for a /bin folder, and you'll find the mysql.exe client around. Let's assume it is in c:\xampp\mysql\bin, then you should fireup a command prompt in this folder.
That means, fire up "cmd", and type:
cd c:\xampp\mysql\bin
mysql.exe -u root --password
If you want to use mysqldump.exe, you should also find it there.
Log into your mysql server, and start typing your commands.
On the Mac, or at least on my Mac using a default install, I accessed it at:
/Applications/xampp/xamppfiles/bin/mysql -uroot -p
For Linux:
/opt/lampp/bin/mysql -u root -p
To use just 'mysql -u root -p' command then add '/opt/lampp/bin' to the PATH of the environment variables.
To access the mysql command in Windows without manually changing directories, do this:
Go to Control Panel > System > Advanced system settings.
System Properties will appear.
Click on the 'Advanced' tab.
Click 'Environment Variables'.
Under System Variables, locate 'Path' and click Edit.
Append the path to your MySQL installation to the end of the exisiting 'Variable value'. Example:
%systemDrive%\xampp\mysql\bin\
or, if you prefer
c:\xampp\mysql\bin\
Finally, open a new command prompt to make this change take effect.
Note that MySQL's documentation on Setting Environment Variables has little to say about handling this in Windows.
Open the XAMPP control panel.
Click Shell.
Type mysql --user=your_user_name --password=your_password.
You can access the MySQL command line with XAMPP for Windows
click XAMPP icon to launch its cPanel
click on Shell button
Type this mysql -h localhost -u root and click enter
You should see all the command lines and what they do

ALTER TABLE)
(Defaults to on; use --skip-progress-reports to disable.)
--prompt=name Set the mysql prompt to this value.
--protocol=name The protocol to use for connection (tcp, socket, pipe,
memory).
-q, --quick Don't cache result, print it row by row. This may slow
down the server if the output is suspended. Doesn't use
history file.
-r, --raw Write fields without conversion. Used with --batch.
--reconnect Reconnect if the connection is lost. Disable with
--disable-reconnect. This option is enabled by default.

-v, --verbose Write more. (-v -v -v gives the table output format).
-V, --version Output version information and exit.
-w, --wait Wait and retry if connection is down.
--connect-timeout=# Number of seconds before connection timeout.
--max-allowed-packet=#
The maximum packet length to send to or receive from
server.
--net-buffer-length=#

translated to '\n'. This switch turns off both features,
and also turns off parsing of all clientcommands except
\C and DELIMITER, in non-interactive mode (for input
piped to mysql or loaded using the 'source' command).
This is necessary when processing output from mysqlbinlog
that may contain blobs.

Ajay,
The reason that you can't see the other tables is that you need to log in as 'root' in order to see them
mysql -h localhost -u root
In terminal:
cd C:\xampp\mysql\bin
mysql -h 127.0.0.1 --port=3306 -u root --password
Hit ENTER if the password is an empty string. Now you are in.
You can list all available databases, and select one using the fallowing:
SHOW DATABASES;
USE database_name_here;
SHOW TABLES;
DESC table_name_here;
SELECT * FROM table_name_here;
Remember about the ";" at the end of each SQL statement.
Windows cmd terminal is not very nice and does not support Ctrl + C, Ctrl + V (copy, paste) shortcuts. If you plan to work a lot in terminal, consider installing an alternative terminal cmd line, I use cmder terminal - Download Page
Go to /xampp/mysql/bin
and find for mysql. exe
open cmd, change the directory to mysq
after write in cmd
mysql -h localhost -u root
Xampp control panel v2.3.1
I got errors while using -h localhost
mysql -h localhost -u root
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10060)
So, if you installed xampp as is and did not customize any documentroot, serverroot, etc. then the following works :-
start both the services on the xampp control panel
click shell
enter: # mysql -h 127.0.0.1 -u root
that works just fine.
Below is the logtrail:-
# mysql -h 127.0.0.1 -u root

To access MySQL in Windows you need to install the XAMPP.
Open the XAMPP Control Panel and start MySQL.
Now go to the command prompt and open
C:\>cd xampp
C:\xampp>cd MySQL
C:\xampp\mysql>cd bin
C:\xampp\mysql\bin>mysql -h localhost -u root
Your database is now ready to be executed.
I had the same issue. Fistly, thats what i have :
win 10
xampp
git bash
and i have done this to fix my problem :
go to search box(PC)
tape this environnement variable
go to 'path' click 'edit'
add this "%systemDrive%\xampp\mysql\bin\" C:\xampp\mysql\bin\
click ok
go to Git Bash and right click it and open it and run as administrator
right this on your Git Bash winpty mysql -u root if your password is empty
or winpty mysql -u root -p if you do have a password
run xampp shell to solve connect to root using pw
mysql -h localhost -u root -p and enter root pw
To access SQL via the command line we simply navigate to the xampp folder.
the folder is usually on the c:\ drive.
type: cd c:\xampp\mysql\bin then press enter.
type: in mysql -u root -p then press enter.
in the new line enter the password of the database.
type: show databases; to see all the databases that you have access to.
once you know what database you want to use type (ex. cms_database), type use cms_data or any other db_name, it should say Database changed
// Bonus Note
you shouldn't use the root user when working with databases. you would want to create a separate account (ex. cms_user) with special privileges to limit errors.
to do that type:
GRANT ALL PRIVILEGES IN cms_database.*
TO 'cms_user'#'localhost'
IDENTITIED BY 'yourpassword'
double check by using the command:
SHOW GRANT FOR 'cms_user'#localhost;
if you already have the name of the user and the specific database you wish to use, change step 2 to this.
mysql -u cms_user -p cms_database
For windows
cd\xampp\mysql\bin
mysql -u root -p
Just a simple commands for linux to open mysql :
sudo /opt/lampp/bin/mysql
to enter MySQL's command-line interface, I find this:
C:\xampp\mysql\bin\mysql -u root
for linux users who are getting
Command 'mysql' not found, but can be installed with:
sudo apt install mysql-client-core-8.0 # version 8.0.30-0ubuntu0.20.04.2, or
sudo apt install mariadb-client-core-10.3 # version 1:10.3.34-0ubuntu0.20.04.1
but have xampp installed
you can just add /opt/lampp/bin to your bashrc file and run mysql
