I created a data base using mysql. I used MySQLDump to create one database backup file in text format (MySql 5.5 on Windows XP). The database is local on my machine (local host).
I am having trouble using the MySQL command to load the dump file to restore the database. I have done the following:
Research stack overflow for how to do it. I noticed there's a bug using the MySQL command to restore the data from a post. Before I run the command, I DROP the database and CREATE the database using MySQL workbench.
I type the following command in the DOS prompt to restore the database:
mysql -u root -p -h localhost -D matlab_data -o < backup.sql
backup.sql is a the backup file in text format created by MySqlDump.
I am then asked for the password which I enter. I get the DOS prompt right away with no error message. I've waited several hours for the command to run and the database is still empty.
I have tried various command formats over the last few days. If I enter incorrect data in the command line (non existen file, database, etc), I get an error message.
I feel I would not see the DOS prompt until the database is restored. If I don't DROP and CREATE the database, I get an error message. Otherwise, not.
Does anybody have any idea what the issue is? I realize that I could be making a stupid mistake.
Thank you for your help.
shell into the mysql console and run the sql file as this
If you are already running mysql, you can execute an SQL script file using the source command or . command:
mysql> source file_name
mysql> \. file_name
note that file_name must be an absolut path

I am attempting to upload a .txt file into my sql database I just created.
I was able to load several lines of data into the table using INSERT INTO, but when I tried to utilize LOAD DATA LOCAL INFILE '/pathto/file.txt' INTO TABLE mytable, it first gave me the error that command is not allowed in my version of mysql.
So after I read How can I correct MySQL Load Error, I used the --local-infile=1 -u mysqlname -p followed by the above command I have repeatedly been awarded the syntax error.
I've tried this to load the .txt file with all sorts of different combinations of the above, and still get one of the two errors.
Below is a screen shot.
This is with ubuntu 15.10 and mysql version 5.6.28-0ubuntu0.15.10.1.
Screen shot of terminal in question
--local-infile is a server and client parameter. It's not valid syntax as part of a statement such as LOAD DATA or INSERT statement.
You would specify server variables and options either in the appropriate sections of the my.cnf file, or as command line parameters to the MySQL program being executed.
For example, at the OS prompt...
# mysql -h myserverhost -u mysqlname -p --local-infile=1
That option has to be specified for the MySQL server.
If you are connecting as user#localhost, you don't need LOCAL. You can give the MySQL user (whichever OS user the mysql server is running under) read privilege on the file you want to load... chmod ugo+r /mypath/myfile (and read execute on the directories in the path.
You only need LOCAL if the msyql user isn't #'localhost'.
I'm executing on a Centos Linux server this command:
mysql -u root -p mydatabase < dump.sql
I enter the password. It seems that all is ok because I absolutely get no errors, no messages that something happened. But sadly, the file is not imported!
Tryed in different ways:
-Putting the sql file in another location.
-Creating the DB first and than without the DB.
-Avoiding the dbname
-Adding max_allowed_packet=800M in /etc/my.cnf (because the file is 490mb)
-Restarted Mysql. But nothing to do. No errors, no import. I'm stuck and in panic. What to do? ?
If you have already created database then use below steps to import data from .sql file
DataBase to use:
use DataBaseName;
Give the source file path
source /path/to/dump.sql;
Hope this will help
Scenario: building a RoR enviroment locally for development. Production is on EngineYard / GitHub. All now working ok, except DB isn't importing.
I have a .sql file that i've taken from my prod EY site. Now i need to import it to my MySQL locally. I'm using Workbench (as i'm new to this), but getting error below.
Please help?
08:07:43 Restoring /home/james/Downloads/Futology.sql Running: mysql
--defaults-extra-file="/tmp/tmpAVeE58/extraparams.cnf" --host=localhost --user=root --port=3306 --default-character-set=utf8 --comments < "/home/james/Downloads/Futology.sql" ERROR 1046 (3D000) at line 22: No database selected

Workbench doesn't know the database (schema) you want to use.
In workbench, when using Data Import/Restore, just below where you choose the file to import, it asks "Default Schema to be Imported To"
Just choose the database (schema) you want it to use from the dropdown titled Default Target Schema. If you don't have a database (schema) already, you can create it with the "New" button.
This is confusing because MySQL generally seems to use the term database but Workbench uses schema. They mean the same thing for most purposes. MySQL 'create schema' and 'create database' - Is there any difference
Not used Workbench too much however it's easy enough to do from command line have a look at this (below phpMyAdmin instructions)
The command you're after is:
mysql -u #username# -p #database# < #dump_file#
Simply by choosing your target schema
As I circled in above image
Similar to brynn's answer, simply modify your SQL file and insert the following line at the very top:
use yourdatabasename
Replacing yourdatabasename with the database into which you are trying to import. Also, this database should already be created (albeit empty) before you import into it.
Here's another option that worked for me. I'm using MySQL 5.5 on a VM I set up for importing a large MySQL .sql dump that contained: 1). a create table statement 2). insert statements for inserting a large amount of data into the table.
at the MySQL command line client prompt type:
use yourdatabasename
source d:\yourpath\yourfilename.sql
for more info on the 'source' and other commands, enter ? at the prompt.
The above command line is correct. I found I have to do this when importing .sql files from older versions of MySQL. I also found I had to edit the .sql file (top of the file) and set the db name to be the same as the blank db you create before doing the import.
I have a database called nitm. I haven't created any tables there. But I have a SQL file which contains all the necessary data for the database. The file is nitm.sql which is in C:\ drive. This file has size of about 103 MB. I am using wamp server.
I have used the following syntax in MySQL console to import the file:
mysql>c:/nitm.sql;
But this didn't work.
From the mysql console:
mysql> use DATABASE_NAME;
mysql> source path/to/file.sql;
make sure there is no slash before path if you are referring to a relative path... it took me a while to realize that! lol
Finally, i solved the problem. I placed the `nitm.sql` file in `bin` file of the `mysql` folder and used the following syntax.
C:\wamp\bin\mysql\mysql5.0.51b\bin>mysql -u root nitm < nitm.sql
And this worked.
If you are using wamp you can try this. Just type use your_Database_name first.
Click your wamp server icon then look for MYSQL > MSQL Console then run it.
If you dont have password, just hit enter and type :
mysql> use database_name;
mysql> source location_of_your_file;
If you have password, you will promt to enter a password. Enter you password first then type:
mysql> use database_name;
mysql> source location_of_your_file;
location_of_your_file should look like C:\mydb.sql
so the commend is mysql>source C:\mydb.sql;
This kind of importing sql dump is very helpful for BIG SQL FILE.
I copied my file mydb.sq to directory C: .It should be capital C: in order to run
and that's it.
In windows, if the above suggestion gives you an error (file not found or unknown db) you may want to double the forward slashes:
In the mysql console:
mysql> use DATABASE_NAME;
mysql> source C://path//to//file.sql;
Ok so, I'm using Linux but I think this holds true for Windows too.
You can do this either directly from the command prompt
> mysql -u <user name> -p<password> <database name> < sqlfilename.sql
Or from within the mysql prompt, you can use:
mysql>source sqlfilename.sql
But both these approaches have their own benefits in the results they display.
In the first approach, the script exits as soon as it encounters an error. And the better part, is that it tells you the exact line number in the source file where the error occurred. However, it ONLY displays errors. If it didn't encounter any errors, the scripts displays NOTHING. Which can be a little unnerving. Because you're most often running a script with a whole pile of commands.
Now second approach (from within the mysql prompt) has the benefit that it displays a message for every different MySQL command in the script. If it encounters errors, it displays the mysql error message but continues on through the scripts. This can be good, because you can then go back and fix all the errors before you run the script again. The downside is that it does NOT display the line numbers in the script where the errors were encountered. This can be a bit of a pain. But the error messages are as descriptive so you could probably figure out where the problem is.
I, for one, prefer the directly-from-OS-command line approach.
If you are using xampp
C:\xampp\mysql\bin\mysql -uroot -p nitm < nitm.sql
You are almost there
use
mysql> \. c:/nitm.sql;
You may also access help by
mysql> \?
For localhost on XAMPP. Open a cmd window and type
cd C:\xampp\mysql\bin
mysql.exe -u root -p
Attention! No semi-colon after -p
Enter your password and type
use database_name;
to select the database you need.
Check if your table is there
show tables;
Import from your sql file
source sqlfile.sql;
I have put my file on C:\xampp\mysql\bin location in order to don't mix up with locations of sql file.
Try:
mysql -u username -p database_name < file.sql
Check MySQL Options.
Note: It is better to use the full path of the SQL file file.sql.
Don't forget to use
charset utf8
If your sql file is in utf-8 :)
So you need to do:
cmd.exe
mysql -u root
mysql> charset utf8
mysql> use mydbname
mysql> source C:\myfolder\myfile.sql
Good luck ))
In Linux I navigated to the directory containing the .sql file before starting mysql. The system cursor is now in the same location as the file and you won't need a path. Use source myData.sql where my date is replaced with the name of your file.
cd whatever directory
mysql - p
connect targetDB
source myData.sql
Done
from the command line (cmd.exe, not from within mysql shell) try something like:
type c:/nite.sql | mysql -uuser -ppassword dbname
Does your dump contain features that are not supported in your version of MySQL? You can also try to remove the starting (and ending) MySQL commented SET-statements.
I don't know if your dump comes from a Linux version of MySQL (line endings)?
I have installed my wamp server in D: drive so u have to go to the following path from ur command line->(and if u have installed ur wamp in c: drive then just replace the d: wtih c: here)
D:\>cd wamp
D:\wamp>cd bin
D:\wamp\bin>cd mysql
D:\wamp\bin\mysql>cd mysql5.5.8 (whatever ur verserion will be displayed here use keyboard Tab button)
D:\wamp\bin\mysql\mysql5.5.8>cd bin
D:\wamp\bin\mysql\mysql5.5.8\bin>mysql -u root -p password db_name < "d:\backupfile.sql"
here root is user of my phpmyadmin
password is the password for phpmyadmin so if u haven't set any password for root just nothing type at that place,
db_name is the database (for which database u r taking the backup)
,backupfile.sql is the file from which u want ur backup of ur database and u can also change the backup file location(d:\backupfile.sql) from to any other place on your computer
mysql>c:/nitm.sql;
That would write the output of the mysql command to 'nitm.sql;' (What's the ';' supposed to do?) Assuming you've got a copy of the original file (before you overwrote it) then:
mysql < c:/nitm.sql
Export Particular DataBases
djimi:> mysqldump --user=root --host=localhost --port=3306 --password=test -B CCR KIT >ccr_kit_local.sql
this will export CCR and KIT databases...
Import All Exported DB to Particular Mysql Instance (You have to be where your dump file is)
djimi:> mysql --user=root --host=localhost --port=3306 --password=test < ccr_kit_local.sql
In Windows OS the following commands works for me.
mysql>Use <DatabaseName>
mysql>SOURCE C:/data/ScriptFile.sql;
No single quotes or double quotes around file name. Path would contain '/' instead of '\'.
For those of you struggling with getting this done trying every possible answer you can find on SO. Here's what worked for me on a VPS running Windows 2012 R2 :
Place your sql file wherever the bin is for me it is located at C:\Program Files\MySQL\MySQL Server 8.0\bin
Open windows command prompt (cmd)
Run C:\Program Files\MySQL\MySQL Server 8.0\bin > mysql -u [username] -p
Enter your password
Run command use [database_name];
Import your file with command source C://Program Files//MySQL//MySQL Server 8.0//bin//mydatabasename.sql
It did it for me as everything else had failed. It might help you too.
I have a MySQL file, db.sql. I have tried to import it using:
mysql -uroot -p[password] db < db.sql
All I get is a listing of mysql commands, or I get a syntax error. The weird thing is I used this file last week and, as far as I know, I'm doing it the same way.
I create the database, then in command line enter the above but it's not working. I've tried being inside mysql and just at command line and nothing seems to be working.
Is there something I should be doing differently in windows or MySQL5? I don't know how the heck I got it to work the first time...
TIA
Try this instead:
mysql -u root -p
(prompts for password)
use db;
source db.sql
I found out it is different to run this command from Windows Command Line (cmd.exe) and Windows PowerShell.
Using CMD.exe the command works okay, but in PowerShell I get this error:
mysql -uroot exampledb < exampledb.sql
The '<' operator is reserved for future use.
Not sure if your example was a typo or not, but for starters you need to have a space in between your flags and their values, roughly like this:
mysql -u root -p [password] db < db.sql
If you are already logged in the try this it will be very useful, but depend upon the MySQL version, it works on MySQL 5.0
For log in if you are not already logged in.
mysql>[your password]
Other wise, use the database to which you want to import the SQLDump file by command.
mysql>use [your database name]
And then give source the database Dump file path as blow command(If not works the copy Dump database file to the bin folder where the MySQL installed for eg. "C:/programfiles/mysql/mqlserver5.0/bin")
mysql> source [dataBasePath+name.sql or dataBaseName.sql]
I've been using PHP script called "BigDump":
http://www.ozerov.de/bigdump.php
This perfectly works
mysql>[your password]
Other wise, use the database to which you want to import the SQLDump file by command.
mysql>use [your database name]
And then give source the database Dump file path as blow command(If not works the copy Dump database file to the bin folder where the MySQL installed for eg. "C:/programfiles/mysql/mqlserver5.0/bin")
mysql> source [dataBasePath+name.sql or dataBaseName.sql]EG: source C:.....sql
I am using mysql server 5.5
In Windows PowerShell, you can pipe in the contents like so:
Get-Content db.sql | mysql -u root -p [password]
