SQL DATABASE DUMP / TEXT PARSE - mysql

can i dump a database to be like...
(username).txt
and then on it the password?
likes this at :
link and this link
or like at this...
put in a .txt file and then dump like that way?

You have to externally encrypt your file.
As the resulting sql file is a text file. Use zip or rar to compress and cypher your data.
In more Detail for windows please search for other operating systems or other programs than 7zip
First make a backup
mysqldump --routines yourdatabase/schema > outputfile.sql
There are a lot of options, so check https://dev.mysql.com/doc/refman/8.0/en/mysqldump.html
Now start for example 7zip File Manager
Select the nackup dile outputfile.sql
And click on add
This dialog appears
Give your new compressed file a name. enter a password.
Slect sfx if your are not shure, if 7zip is installed on the maschine where you have to restore your database
Winzip and winrar have their own methods.
There are of course solutions, which you can use at a command prompt. see https://dba.stackexchange.com/questions/5831/how-do-you-encrypt-data-while-performing-a-mysqldump

MySQL command line, source to import many files

Is it possible to import many .sql files using the source command in mysql command line interface?
if u have files like
1.sql
2.sql
...
n.sql
Create a file example.sql include
source 1.sql
source 2.sql
....
source n.sql
Connect to mysql and source example.sql
source example.sql
Source multiple files is not possible, but u can include the files to source in a file and source a single file for automating.

mysql: SOURCE error 2?

When I tried to source for a particular .sql file, namely 'metropolises.sql' that I created and saved previously from a database, the following error is displayed:
Failed to open file 'metropolises.sql', error: 2
Any idea what went wrong?
Assuming you mean that you are trying to use the source command in order to execute SQL statements from a text file, the error number given appears to be passed through from the POSIX layer.
Therefore, using this resource, we can deduce that the error value of 2 means "no such file or directory".
In short, you got the path wrong.
Try providing an absolute path, as it's not clear what the current working directory will be in the context of your MySQL server. You may be assuming that it's the working directory of your shell, but it's not obvious that we should expect this to be true.
Just use the absolute path of the file and then, instead of using backslashes, use forward slashes.
Example:
with backslashes : source C:\folder1\metropolises.sql
with forward slashes : source C:/folder1/metropolises.sql
IF YOU ARE USING MYSQL INSIDE DOCKER
Note that if you are running MySQL inside docker then you must first copy the dump into your MySQL docker environment. To do that follow the steps below
First, check and copy the container ID for your MySQL docker by:
sudo docker ps
Copy the SQL dump file into your container using:
sudo docker cp /path/to/sql/file.sql MysqlDockerID:/
This will copy the dump file into the docker root folder if you want to copy the file inside any other directory/path inside docker replace the '/' after 'MysqlDockerID:' with the path you want appropriate one.
Now to interact with MySQL inside a running container run the following command:
sudo docker exec -it MysqlDockerID bin/bash
Now connect to the MySQL using the terminal by:
mysql -u yourUserName -p
This will now ask you for the password. Enter the correct password to proceed.
List the databases available by:
show Databases;
This will list out the available databases
Assuming your database name where you want to import dump to is 'MyDatabase'. Switch to that using:
use MyDatabase
Now you can import the file by typing:
source file.sql
Remember the above command works if you have copied your file into your root folder (using step 2). If you have copied it to any other path make sure you use that same path instead
Related issue I had getting error 2 running source command: filename must not be in quotes even if it contains spaces in name or path to file.
It's probably the file path to your file. If you don't know the exact location of the file you want to use, try to find your file in Finder, then drag the file into Terminal window
mysql> SOURCE dragfilePathHere
I first reach to the file
c:\windows>cd c:\akura\Db Scripts
c:\akura\Db Scripts>mysql -u root -p root
mysql>\. EXECUTER_NEW_USER.sql
here EXECUTER_NEW_USER.sql my file name
I've had the same error on Windows.
I solved it with (after on cmd: mysql -u root):
mysql> SOURCE C:/users/xxx/xxxx/metropolises.sql;
Be sure you type the right file path
On my windows 8.1, and mysql 5.7.9 MySQL Community Server (GPL),
I had to remove the ; after the file path.
This failed: source E:/jokoni/db/Banking/createTables.sql;
This Worked: source E:/jokoni/db/Banking/createTables.sql
(without termination, and forward slashes instead of windows' backslashes in path)
If you are using vagrant ensure that the file is on the server and then use the path to the file. e.g if the file is stored in the public folder you will have
sql> source /var/www/public/xxx.sql
Where xxx is the name of the file
I got this error in mysql command line using this query:
source `db.sql`;
I changed the above to the following to make it work:
source db.sql;
On my Mac, this is the only solution worked for me.

1 - Download the .sql file and remember it's location.
2 - Open your mysql from command prompt or terminal.
3 - Create a database with the same name as that of the database present in the .sql file (create database your_database_name)
4 - Now exit out from the mysql command line client
5 - Now try and execute this command =>
mysql -u your_username -p your_database_name < your_sql_file_with_complete_location
example - mysql -u root -p trial < /home/abc/Desktop/trial.sql
here my .sql file is named trial and is present in the desktop, the database is also name trial
6 - You should now have your sql file imported to the corresponding mysql database.
I was having this issue and it turns out if you are using wamp server to run mysql, you have to use the file path within the wamp64 folder. So when the absolute path is: C:/wamp64/www/foldername/filename.sql
The path you have to use is:
www/foldername/filename.sql
May be the file name or path you are used may be incorrect
In my system i created file abcd.sql at c:\
and used command mysql> source c:\abcd.sql Then i got result
If you're on Debian 8 (Jessie) Linux, try to cd into the directory of the 'metropolises.sql'. Run mysql and execute SOURCE ./metropolises.sql;
Basically, try the relative path. I tried this and it works.
If you are running dockerized MySQL container such as ones from this official Docker Image registry: https://hub.docker.com/_/mysql/ You may encounter this issue as well.
For me it was because the file was located on a shared drive and it could not access, for some reason, to that path.
I cut the file and put it on my local drive in a path without spaces and it got resolved.
I got the same error when i used the command source and gave the sql file path by drag n dropping it.
Then I just had to remove those single quotes which appeared by default with drag and drop, a space before file extension and it worked.
soln:
source /home/xyz/file .sql ;(path and a space before file extension)
For Mac users, you can give the path as,
source /Users/YOUR_USER_NAME/Desktop/metropolises.sql;
*I have assumed that the file you need to source is in your desktop and the file name is metropolises.sql
If you type,
source metropolises.sql
then the file will be look in the default location,
/Users/YOUR_USER_NAME/metropolises.sql;
The solution for me was file permissions in Windows. Just give full control in the file to all users and it will work. After the import, get the permissions back to what it was before.
I had a problem on my Mac because one of the folder (directory) names in the path had a space in the name. BTW, the space was escaped by a \, but that was not understood by mySQL
solution - 1) Make sure you're in the root folder of your app. eg app/db/schema.sql.
solution - 2) open/reveal the folder on your window and drag&&drop in the command line next to keywork source (space) filesource. eg source User/myMAC/app/db/schema.sql
I get into this problem in my Xubuntu desktop. I fixed it by renaming all my files and folders so there is no space in the file path.
Passing the full path does not error, but if the folders have MySQL spaces it does not recognize the .sql file.
I have MySQL 8.0.21 on OS UNIX.
I've got the same error on Windows. I solved it running the code on MySQL command line
source c:\Users\xx\Downloads\data_file.sql
Remove spaces in the folder names of the path, It worked for my mac path.
(Eg: change the folder name MySQL Server 5.1 to MySQLServer5.1)
I also got the same message when I try from the MySQL console. However, when I open the command prompt and do the same steps it works.
C:\Users\SubhenduD>cd ../
C:\Users>cd ../
C:\>cd \xampp\mysql\bin
C:\xampp\mysql\bin>mysql -u -root

Importing zipped files in Mysql using CMD

I am trying to import zipped database files into Mysql using command prompt using the following command
7z < backup.sql.7z | mysql -u root test
The root user don't have any password associated with it.
test is my target blank database.
I use 7zip for unzipping purpose.
The zipped database i.e. backup.sql.7z is located in D drive.
But it's giving the following error
So, instead I used the following command
7z < backup.7z | mysql -u root test
Note: This time I am using backup.7z instead of backup.sql.7z
But then I get the following error
Clearly there's something wrong with my SQL syntax.
What will be the correct syntax to use then ?
I needed to import from a compressed file as well, and stumbled upon your question.
After a bit of messing around, I found that this worked for me:
7z x -so backup.7z | mysql -u root test
x is the extraction command
-so makes 7-zip write to stdout
Nothing wrong with your syntax, it's just a limitation with 7zip. It's better to use xz in this case, which doesn't put extraneous junk in stdout, or directly call the 7z.dll with your favorite programming language. 7z.exe is really meant for archive management, rather than unix-style piping, and Igor is very reluctant to change that.
If you try a plain 7z < somefile.7z you'll immediately see that all you get back is a usage list.

Retrieve lost file using Vi in MySQL

I would like to know how to retrieve a file using Vi in MySQL. I logged in using:
mysql -uuser -p -hserver -A database
Then I do:
\e
The editor opens and I type my query of 200 lines, then I :wq and \G (if I save the file it says: /tmp/sql9SbYQZ saved) and I see the result.
Now, if I make a mistake or run a different query and I try to type \e again, the query is lost.
ll /tmp/sql9SbYQZ
ls: /tmp/sql9SbYQZ: No such file or directory
Is there a way to retrieve the lost file?
Here's what I added to my .vimrc in order to save the current query in case i made a mistake.
nmap <F7> :w! /tmp/query.sql\| wq!<CR>
This will create a map to the F7 key (you can change it of course). So every time you open a file either using edit or \e, you change it use the F7 key.
This will save a backup of your current query to /tmp/query.sql and then save and close the temporary file. This way, if you make a mistake, you just re-open the backup file and try again.
Here's also a link you might like: http://vim.wikia.com/wiki/Open_the_last_edited_file
With the vi/m editor used with mysql, crontab, and many others, the work is done in a tmp file, as you see from your messages.
Edit (Big doah!, remove cruft about ls -l /tmp/..., you already did that!)
In the future the solution is to tell vim to w the buffer to a file name of your chosing, i.e.
w! /home/you/scripts/mysql2.sql
Then close the editor with
q
Note you may not need the ! after w.
I hope this helps.
Here is something you can try:
In Linux, do the following
$ cd
$ cp .mysql_history mystuff.txt
$ vi mystuff.txt
You should see the file .mysql_history. The mysql client records all queries and commands executed. Hopefully, your query is in there.
Give it a Try !!!

Using mysqlimport where the filename is different from the table name

I've been playing with mysqlimport and I've run into the restriction where the filename has to be the same as the table name. Is there any way to work round this?
I can't rename the file as it is used by other processes and I don't want to copy the file as there will be many of them, some being very large.
I want to use mysqlimport not LOAD INFILE.
EDIT: Unfortunately this needs to run on windows so no tricks with symbolic links I'm afraid.
You didn't say what platform you are on. On unix you can create a symbolic link to the file:
ln -s filename.txt tablename.txt
Then use that in the mysqlimport command.
But mysqlimport is just a command line interface to LOAD INFILE so you could also do this on the command line:
mysql -e "load data infile 'filename' into table TBL_NAME" dbname
mysqlimport uses the filename to determine the name of the table into which the data should be loaded. The program does this by stripping off any filename extension (the last period and anything following it); the result is then used as the table name. For example, mysqlimport treats a file named City.txt or City.dat as input to be loaded into a table named City.
Have you tried using the alias command, assuming you are on a Linux system?
Just create a symbolic link:
ln -s /tmp/real_file.txt /tmp/your_table_name.txt
