How can I import multiple files(.csv, .sql etc) into xampp mysql database ?
I am using Xampp and windows XP.
If I need to write command prompt type command, please tell in details where to find the command prompt type screen and so on.
The SQL files you can execute with MySQL command-line tool, e.g. -
shell> mysql db_name < script.sql
Load data from the CSV file into specified table you can with LOAD DATA INFILE statement.
If you do not have access to mysql client, then try dbForge Studio for MySQL. Free express edition allows to execute SQL scripts and import data from the CSV file without limitations.
This topic has been covered already, in its parts.
to import a CSV you can check this question, which will lead you to use:
LOAD DATA INFILE yourfile.csv
or if you need to update some data that is already on the database you can relate to a question I answered not long ago (and possibly other answers on stackoverflow).
You may execute this statement in the mysql prompt with mysql -u user -p -h localhost -D database (learn how to find the path to mysql.exe in your XAMMP using this question) or using some other way, such as your scripting/programming language of choice together with mysql connectors/libraries.
You may also use the mysqlimport.exe command (it'll be in the same folder as your mysql binary).
To import a sql file you can take a look at this question. You will essentially just copy the file contents into the mysql prompt, which is usually done with input redirection on the console:
C:>mysql -u user -p -h localhost -D database -o < yoursqlfile.sql
I hope that besides answering your question i might also have introduced you to the fact that with thousands(?) of questions in stackoverflow you are very likely to find the answers to your doubts by searching the questions database, possibly faster than asking your own new question.

I used this command mysqldump -u root -p etl_db > ~/backup.sql to get the backup data.
Now I want to import into a new remote MySQL database.
I saw there are 2 ways to do it.
https://dev.mysql.com/doc/refman/8.0/en/mysql-batch-commands.html
I wonder which one would be faster?
shell> mysql < dump.sql
or
mysql> source dump.sql?
I saw some people says that source is for small data but there are others say that it's good for large data. I couldn't find much documentation.
Thanks!
I have 5GB database that needs to be uploaded to phpmyadmin and that too on the shared server where i cannot access the shell.Is there any solution that can take lesser time to upload? Please do help me by providing the steps to upload the sql file. I have searched through internet but could not find an answer.
Do not use phpmyadmin.
Assuming you have shell, upload the file and feed it directly to mysql command.
Your shell command will look like:
cat file.sql | mysql -uuser -ppassword database
or you can do gzipped file:
zcat file.sql.gz | mysql -uuser -ppassword database
Prior doing this check:
database connection works (correct database, user and password)
database is empty :)
mysql max packet size is OK
you have enough diskspace
* UPDATE *
You said you do not have shell access.
Then you have following options -
upload the file and contact support, let they do it for you.
feed it remote, cpanel have special menu where you can get remove access, other panels have same ability too.
in this case code will be executed on your computer and look like:
cat file.sql | mysql -uroot -phipopodil -hwebsite.com
or for windows:
/path/to/mysql -uroot -phipopodil -hwebsite.com < file.sql
do some "hack" - feed it through crontab, at or via php system() command.
If you choose "hack" option, note following:
php have max_execution_time - even if you set it to zero, there could be some limit "imposed" from hosting.
usually hosts have limited mysql updates per hour.
there could be some ulimit restrictions.
if you execute feeding of 5 GB on shared server, server will slow down and administrator will check what you are doing.
This depends on your database, you tagged it with 3 different database types, mysql, sql-server, and postgresql. I know mysql and postgresql have import features, although I'd be surprised if SQL Server didn't as well. You could import the database file via the command line instead of having to use phpmyadmin.
Incidentally, the phpmyadmin tool also has an import feature, but that again depends on the format of your database. If it's a compatible sql file, you could upload it to phpmyadmin and import it there, but I'd recommend the previous method I mentioned, upload it to your host, then use whatever database tool (mysqlimport for mysql, or if it's the result of a pg_dump command, you can just run:
psql <dbname> < <yourfile>
ie
psql mydatabase < inputfile.sql
i have a .sql file that was exported from wamp, my friend only uses xampp. Is it possible to import my .sql file to xampp?
Yes because the .sql file is most likely independent of the server stack.
Of course it is possible, when wamp give you a export of .sql, this file can be used with all standard web server. (xampp)
I think this may help
Depending on the tool and parameters used to create the .sql dump file of multiple databases, the file will normally have
CREATE DATABASE DBn...;
and
USE DBn;
statements that will allow your import to proceed without hiccups. For example, both the mysqldump command mysqldump command and phpMyAdmin's Export function for multiple database insert them.
Assuming you have exported with a sensible tool like those above, then you can import the database with a command line like this:
mysql -u username -p < dumpfile.sql
Your mysql username account needs to have appropriate privileges to, for example, create databases.
You can even run this command in a more familiar way by naming the startingDB database to use before running the commands in dumpfile.sql:
mysql -u username -p startingDB < dumpfile.sql
A mysqldump command like the following:
mysqldump -u<username> -p<password> -h<remote_db_host> -T<target_directory> <db_name> --fields-terminated-by=,
will write out two files for each table (one is the schema, the other is CSV table data). To get CSV output you must specify a target directory (with -T). When -T is passed to mysqldump, it writes the data to the filesystem of the server where mysqld is running - NOT the system where the command is issued.
Is there an easy way to dump CSV files from a remote system ?
Note: I am familiar with using a simple mysqldump and handling the STDOUT output, but I don't know of a way to get CSV table data that way without doing some substantial parsing. In this case I will use the -X option and dump xml.
mysql -h remote_host -e "SELECT * FROM my_schema.my_table" --batch --silent > my_file.csv
I want to add to codeman's answer. It worked but needed about 30 minutes of tweaking for my needs.
My webserver uses centos 6/cpanel and the flags and sequence which codeman used above did not work for me and I had to rearrange and use different flags, etc.
Also, I used this for a local file dump, its not just useful for remote DBs, because I had too many issues with selinux and mysql user permissions for SELECT INTO OUTFILE commands, etc.
What worked on my Centos+Cpanel Server
mysql -B -s -uUSERNAME -pPASSWORD < query.sql > /path/to/myfile.txt
Caveats
No Column Names
I cant get column names to appear at the top. I tried adding the flag:
--column-names
but it made no difference. I am still stuck on this one. I currently add it to the file after processing.
Selecting a Database
For some reason, I couldn't include the database name in the commandline. I tried with
-D databasename
in the commandline but I kept getting permission errors, so I ended using the following the top of my query.sql:
USE database_name;
On many systems, MySQL runs as a distinct user (such as user "mysql") and your mysqldump will fail if the MySQL user does not have write permissions in the dump directory - it doesn't matter what your own write permissions are in that directory. Changing your directory (at least temporarily) to world-writable (777) will often fix your export problem.
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
