Need to access SQL using "mysql root -p" - mysql

Hey guys: I have one question access mysql using command line. I have no problem to access mysql based on this commend line "mysql --host=localhost --user=root --password="mypassword""; however, I have issue access mysql using the conventional way: "mysql root -p". I've tried many times to change root password. But I still only can access mysql using this commend line "mysql --host=localhost --user=root --password="mypassword"". Any comments are welcoming!

You have incorrect command as conventional way.
The error you mentioned in comment indicates that MySQL username is "ODBC" & you are not passing proper MySQL user in the command line. That is happening because you are using "mysql root -p".
Correct command is "mysql -u root -p". You missed the "-u " part.

MySQL Shell always gives error no matter what I type

I have even switched to the \sql mode.
I have tried \connect root#localhost;
I have tried with mysql --host=localhost --port=3306 --user=root -p;
I am new to this . I installed the entire .msi package too.
If i run the MySql Command Line Client, everything works.
This brings me to another doubt. What is the purpose of MySQl shell?

MySql 1045 When using --defaults-file

I am having a strange issue. I have MySql running on RHEL. I can logon to MySql with
mysql -uroot -pmyPassword
and it works fine. Also, when I try to execute a query from a .sh script as below it works fine
mysql --user=root --password=myPassword --host=localhost --port=3306 -se "SELECT 1 as testConnect" 2>&1>> $OUTPUT
But when I store the userid and password in a msql.conf file as below
[clientroot]
user=root
password=myPassword
and then change the line in the script as below
mysql --defaults-file=msql.conf --defaults-group-suffix=root -hlocalhost -P3306 -se "SELECT 1 as testConnect" 2>&1>> $OUTPUT
When I run it, I get the error:
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
I am running the script with sudo and the config file is at the same directory as the script
I have permission 0600 on the config file.
How do I make this work?
It worked for me, but it was a bit of a 'tricky' fix that isn't shown in the actual documentation. All you have to do is change
[clientroot]
user=root
password=myPassword
to
[clientroot]
user="root"
password="myPassword"
Basically just add the double quotes.
Then running your command:
mysql --defaults-file=msql.conf --defaults-group-suffix=root -hlocalhost -P3306 -se
"SELECT 1 as testConnect" 2>&1>> $OUTPUT
Should work (it worked for me).
I discovered this by looking through an obscure part of the documentation on something almost unrelated, so I don't blame everyone for missing it.
Options files are not meant for auto-login credentials.
Try this:
export MYSQL_PWD=myPassword
And try to connect using the root user.
Note that this approach is "insecure", but so is the basic idea of what you're trying to do.
When your goal is to not use the password in scripts or on command line, may I suggest a different approach?
You can create a file with the login credentials encrypted and use that for logging in.
Here's an example:
Create the file with
mysql_config_editor --set-login-path=local --host=localhost --user=localuser --password
This creates the file ~/.mylogin.cnf. You can now login with
mysql --login-path=local
local is a name you can specify, btw.
Here's another plus: You can also create different files for different projects. For example, I sometimes create files for certain scripts. I put the .mylogin.cnf in the same folder as the script and use it like this in the script:
RESULT=($(MYSQL_TEST_LOGIN_FILE=./.mylogin.cnf mysql --login-path=$HOST -B --skip-column-names -e "SELECT whatever FROM whatever"))

mysqldump Error 1045 Access denied despite correct passwords etc

This is a tricky one, I have the following output:
mysqldump: Got error: 1045: Access denied for user 'root'#'localhost' (using password: YES) when trying to connect
When attempting to export my database with mysqldump on Windows XP. The username is root, the password is correct and contains only alphanumeric characters. I have tried different cases, with/without quotes, specifying using -u and -p, specifying using --user= and --password= and other methods of specifying user/passwords etc, specifying the host (it's all local) and even specifying the database using --databases instead of just blank. The error is always the same when using a password and always the same except the "NO" message when without. I have tried many fixes found through searches with no success. One fix suggested inspecting mysql.conf, but the Windows build doesn't seem to have one. The credentials (and indeed commandline parameters) work perfectly with mysql.exe - this problem only seems to be affecting mysqldump.exe.
This worked for me
mysqldump -u root -p mydbscheme > mydbscheme_dump.sql
after issuing the command it asks for a password:
Enter password:
entering the password will make the dump file.
If you're able to connect to the database using mysql, but you get an error for mysqldump, then the problem may be that you lack privileges to lock the table.
Try the --single-transaction option in that case.
mysqldump -h database.example.com -u mydbuser -p mydatabase --single-transaction > /home/mylinuxuser/mydatabase.sql
Try to remove the space when using the -p-option. This works for my OSX and Linux mysqldump:
mysqldump -u user -ppassword ...
The access being denied is probably to the Windows file system not to the MySQL database; try redirecting the output file to a location where your account is allowed to create files.
You need to put backslashes in your password that contain shell metacharacters, such as !#'"`&;
Don't enter the password with command. Just enter,
mysqldump -u <username> -p <db_name> > <backup_file>.sql
Then you will get a prompt to enter password.
Access dined problem solved when I run command prompt in Administrator mode.
Go to Start-> All Programs -> Accessories right click on Command Prompt clickc on Run as.. Select The Following User select administrator username from select option enter password if any click OK button.
Example 1: For entire database backup in mysql using command prompt.
In Windows 7 and 8
C:\Program Files <x86>>\MySQL\MySQL Server 5.5\bin>mysqldump test -u root -p >testDB.sql
Enter Password: *********
In Windows xp
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqldump test -u root -p >testDB.sql
Enter Password: *********
It asks password for credentials enter password and click on Enter button.
Example 2: For specific table backup / dump in mysql using command prompt.
In Windows 7 and 8
C:\Program Files <x86>>\MySQL\MySQL Server 5.5\bin>mysqldump test -u root -p images>testDB_Images.sql
Enter Password: *********
In Windows xp
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqldump test -u root -p images>testDB_Images.sql
Enter Password: *********
Dumpt file will be created under folder
In windows xp
C:\Program Files\MySQL\MySQL Server 5.5\bin
In windows 7 and 8
C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin
Note: Check MySQL installation folder in Windows 7, 8 while run in command prompt. If MySQLWorkbench is 32 bit version it is installed in Program Files (x86) folder other wise Program Files folder.
Put The GRANT privileges:
GRANT ALL PRIVILEGES ON mydb.* TO 'username'#'%' IDENTIFIED BY 'password';
mysqldump -h hostname -u username -P port -B database --no-create-info -p > output.sql
I think you should specify the args
Doing without the -u and -p worked for me (when I was logged in as root):
mysqldump --opt mydbname > mydbname.sql
I was having the same issue, for 30min! I found that I was using _p instead of -p, the terminal font confused me!
Putting -p as the first option worked for me on Windows Server 2012R2 (in cmd.exe as Admin).
mysqldump.exe –p --user=root --databases DBname --result-file=C:\DBname.sql
I just ran into this after a fresh install of MySQL 5.6.16.
Oddly, it works without the password specified or flagged:
mysqldump -u root myschema mytable > dump.sql
mysqldump -u (user) -p(passwd) -h (host_or_IP) database_to_backup > backup_file.sql
example:
mysqldump -u god -pheaven -h 10.0.10.10 accounting > accounting_20141209.sql
this would create sql backup file for the accounting database on server 10.0.10.10. Sometimes your error is seen when localhost is not in config. Designating ip of server may help.
I had to remove the single ticks after the password flag:
--password=mypassword
and NOT
--password='mypassword'
Mysql replies with Access Denied with correct credentials when the mysql account has REQUIRE SSL on
The ssl_ca file (at a minimum) had to be provided in the connection paramiters.
Additional ssl parameters might be required and are documented here: http://dev.mysql.com/doc/refman/5.7/en/secure-connection-options.html
Also posted here https://stackoverflow.com/a/39626932/1695680
For MAMP PRO users (or anyone who's mysql is in a weird location) be prepared to specify the mysql full path from the boonies and also specify full path to your user local folder where you want to dump the file or you'll get the "permission denied error"..
Following worked for me after 3 hours of research:
/Applications/MAMP/Library/bin/mysqldump -u root -proot YOUR_DB > /Users/YOUR_USER/yourdump2.sql
In my case, I could access correctly with mysql.exe but not with mysqldump.exe.
The problem was the port for my connection was not the default one (3306) and I had to put the mysqldump port work with (-P3307)
mysqldump -u root -p -P3307 my_database > /path/backup_database
This is the solution that worked for me
mysqldump -h hostname.com -u username -p'password' database > dump.sql
In Past same problem occurred to me after I copied the mysqldump statement from a MS Word file.
But When typing the statement directly, everything worked fine.
In hex editor the "-" of the not working statement was represented by the unicode char e2 80 93 (http://www.fileformat.info/info/unicode/char/2013/index.htm)
In sort, type password directly and check the copy paste code as the uni-code (or other encoding) strings might cause an issue..
I had the same error for last 2 days. Tried bunch of things. Nothing worked.
But this did work:
Create another user. Grant it everything.
mysqldump -u new_user db_name > db_name.sql //no error
I discovered a running apache process acessing the MYSQL causing this error. So I suggest to ensure that all processes which might interact with the DB are shutdown beforehand.
I had the problem that there were views that had a bad "DEFINER", which is the user that defined the view. The DEFINER used in the view had been removed some time ago as being "root from some random workstation".
Check whether there might be a problem by running:
USE information_schema;
SELECT DEFINER, SECURITY_TYPE FROM views;
I modified the DEFINER (actually, set the DEFINER to root#localhost and the SQL SECURITY value to INVOKER so the view is executed with the permissions of the invoking user instead of the defining user, which actually makes more sense) using ALTER VIEW.
This is tricky as you have to construct the appropriate ALTER VIEW statement from information_schema.views, so check:
Modify DEFINER on many
views
MySQL error 1449: The user specified as a definer does not exist
For me it worked when I omitted the password.
So mysqldump -u user dbname > dump.sql
Tried most of the above with no joy.
Looking at my password, it had characters that might confuse a parser. I wrapped the password in quotes and the error was resolved.
-p"a:##$%^&+6>&FAEH"
Using 8.0
If you want to create a mysql data dump, you can use mysqldump command. Following command will create a sql file called xxx.sql at the same location from where this command is run. xxx.sql will have all the necessary sqls to replicate exactly same db schema in any other mysql database.
Command is : mysqldump -u root -ppassword --databases database Name you want to import > xxx.sql
Here root is the mysql root user and password is THIS root user's password.
EXAMPLE: If root user password is hello, database name to export is regdb and xxx.sql is the file where you want to export this regdb, command would be like:
mysqldump -u root -phello --databases regdb > xxx.sql
Note: xxx.sql is the file name where this db will get dumped.
This solution might be one of the last to try/least likely to be the culprit, but this was my problem...
My problem was that the directory I was trying to dump to needed admin privileges to write to and that's what was causing the mysqldump command to return "Access Denied".
I set the dump file path to my desktop dir and then it worked.
This was on Windows.
I had the same error. Only occurred after moving from my normal work PC to a PC at a different location.
I had to add my public IP ho address to Remote MySQL in my CPanel at my host site
I got the same error when I ran the command in a directory that I didn't have write access to.
Test your access by creating an empty file in the directory, and see if you get an error.
Here was my error
mysqldump -u root librenms -p > librenms.sql
-bash: librenms.sql: Permission denied
I changed to my home directory and then it worked.
cd ~
mysqldump -u root librenms -p > librenms.sql
Enter password:
Do the equivalent on windows, and it may just fix your problem!
ENSURE YOU TRY REMOVING AND TYPING THE DASH OVER to make sure that you are actually fighting with the right problem.
Be very careful that you actually have a "-". I apparently had some other character that looks very similar. I had a – instead of a -. I had copied the command from somewhere online don't remember where but the point is I spend a lot of time trying to figure it out when I just needed to replace that character.

How to run SQL script in MySQL?

I want to execute a text file containing SQL queries, in MySQL.
I tried to run source /Desktop/test.sql and received the error:
mysql> . \home\sivakumar\Desktop\test.sql ERROR: Failed to open file
'\home\sivakumar\Desktop\test.sql', error: 2
Any idea on what I am doing wrong?
If you’re at the MySQL command line mysql> you have to declare the SQL file as source.
mysql> source \home\user\Desktop\test.sql;
You have quite a lot of options:
use the MySQL command line client: mysql -h hostname -u user database < path/to/test.sql
Install the MySQL GUI tools and open your SQL file, then execute it
Use phpmysql if the database is available via your webserver
you can execute mysql statements that have been written in a text file using the following command:
mysql -u yourusername -p yourpassword yourdatabase < text_file
if your database has not been created yet, log into your mysql first using:
mysql -u yourusername -p yourpassword
then:
mysql>CREATE DATABASE a_new_database_name
then:
mysql -u yourusername -p yourpassword a_new_database_name < text_file
that should do it!
More info here: http://dev.mysql.com/doc/refman/5.0/en/mysql-batch-commands.html
My favorite option to do that will be:
mysql --user="username" --database="databasename" --password="yourpassword" < "filepath"
I use it this way because when you string it with "" you avoiding wrong path and mistakes with spaces and - and probably more problems with chars that I did not encounter with.
With #elcuco comment I suggest using this command with [space] before so it tell bash to ignore saving it in history, this will work out of the box in most bash.
in case it still saving your command in history please view the following solutions:
Execute command without keeping it in history
extra security edit
Just in case you want to be extra safe you can use the following command and enter the password in the command line input:
mysql --user="username" --database="databasename" -p < "filepath"
All the top answers are good. But just in case someone wants to run the query from a text file on a remote server AND save results to a file (instead of showing on console), you can do this:
mysql -u yourusername -p yourpassword yourdatabase < query_file > results_file
Hope this helps someone.
I came here searching for this answer as well, and here is what I found works the best for me: Note I am using Ubuntu 16.x.x
Access mysql using:
mysql -u <your_user> - p
At the mysql prompt, enter:
source file_name.sql
Hope this helps.
Give the path of .sql file as:
source c:/dump/SQL/file_name.sql;
mysql> source C:\Users\admin\Desktop\fn_Split.sql
Do not specify single quotes.
If the above command is not working, copy the file to c: drive and try again.
as shown below,
mysql> source C:\fn_Split.sql
instead of redirection I would do the following
mysql -h <hostname> -u <username> --password=<password> -D <database> -e 'source <path-to-sql-file>'
This will execute the file path-to-sql-file
Never is a good practice to pass the password argument directly from the command line, it is saved in the ~/.bash_history file and can be accessible from other applications.
Use this instead:
mysql -u user --host host --port 9999 database_name < /scripts/script.sql -p
Enter password:
mysql -uusername -ppassword database-name < file.sql
So many ways to do it.
From Workbench: File > Run SQL Script -- then follow prompts
From Windows Command Line:
Option 1: mysql -u usr -p
mysql> source file_path.sql
Option 2: mysql -u usr -p '-e source file_path.sql'
Option 3: mysql -u usr -p < file_path.sql
Option 4: put multiple 'source' statements inside of file_path.sql (I do this to drop and recreate schemas/databases which requires multiple files to be run)
mysql -u usr -p < file_path.sql
If you get errors from the command line, make sure you have previously run
cd {!!>>mysqld.exe home directory here<<!!}
mysqld.exe --initialize
This must be run from within the mysqld.exe directory, hence the CD.
Hope this is helpful and not just redundant.
From linux 14.04 to MySql 5.7, using cat command piped with mysql login:
cat /Desktop/test.sql | sudo mysql -uroot -p
You can use this method for many MySQL commands to execute directly from Shell. Eg:
echo "USE my_db; SHOW tables;" | sudo mysql -uroot -p
Make sure you separate your commands with semicolon (';').
I didn't see this approach in the answers above and thought it is a good contribution.
Very likely, you just need to change the slash/blackslash:
from
\home\sivakumar\Desktop\test.sql
to
/home/sivakumar/Desktop/test.sql
So the command would be:
source /home/sivakumar/Desktop/test.sql
use the following from mysql command prompt-
source \\home\\user\\Desktop\\test.sql;
Use no quotation. Even if the path contains space(' ') use no quotation at all.
Since mysql -u yourusername -p yourpassword yourdatabase < text_file did not work on a remote server (Amazon's EC2)...
Make sure that the Database is created first.
Then:
mysql --host=localhost --user=your_username --password=your_password your_database_name < pathTofilename.sql
For future reference, I've found this to work vs the aforementioned methods, under Windows in your msql console:
mysql>>source c://path_to_file//path_to_file//file_name.sql;
If your root drive isn't called "c" then just interchange with what your drive is called. First try backslashes, if they dont work, try the forward slash. If they also don't work, ensure you have your full file path, the .sql extension on the file name, and if your version insists on semi-colons, ensure it's there and try again.
If you are here LOOKING FOR A DRUPAL ENVIRONMENT
You can run with drush command on your project directory
drush sqlc
If you are trying this command :
mysql -u root -proot -D database < /path/to/script.sql
You may get an error like this : if you have special characters, mainly '`'
ERROR 1064 (42000) at line 1: 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 '/path/to/script.sql' at line 1
So I would suggest to use a command like this :
echo "source /path/to/script.sql" | mysql -u root -proot -D database
This command will execute source /path/to/script.sql once connected to the server, which execute your script.
I had this error, and tried all the advice i could get to no avail.
Finally, the problem was that my folder had a space in the folder name which appearing as a forward-slash in the folder path, once i found and removed it, it worked fine.
I use Bash's Here Strings for an instant SQL execution:
mysql -uroot -p <<<"select date(now())"
https://www.gnu.org/software/bash/manual/html_node/Redirections.html#Here-Strings

how do i specify connection parameters on the command line to run mysql in batch mode?

I need to be able to write a script to automatically connect mysql in batch mode so that I can run some .sql files.
I tried to enter the following at the prompt:
./mysql -u root -p mypassword
but I keep getting a "Enter password: " prompt.
What am I doing incorrectly?
Thanks.
Get rid of space. Varies with shell.
mysql -uusername -ppassword dbname
It is likely interpreting "mypassword" as your dbname.
Have you tried --password=mypasswd?
