Mysqldump - How to restore a single table from this file? - php

I need to restore just a single table in my database.
I have a .sql file that has all the info I need for one table but the rest would overwrite important information for other tables.
Instead of using the solution here - using a tool I've never heard of, I figured it would be more sure fire to do it manually.
Unfortunately, the MySqlDump generated a GIANT insert line too long to paste into mysql command line...
What should I do?
Should I use sed like the link above describes?
Or could I copy paste the commands for that specific table from the mysqldump.sql into a new .sql file then call:
mysql -u root -p -h localhost < copyPasteFile.sql


u can try it
mysql -u root -p databasename -h localhost < copyPasteFile.sql


mysql -uuser -ppassword -e "create database temporary"
mysql -uuser -ppassword temporary < copyPasteFile.sql
mysqldump -uuser -ppassword temporary yourtable > onlythattable.sql
mysql -uuser -ppassword therealdb < onlythattable.sql
mysql -uuser -ppassword -e "drop database temporary"
make sure that copyPasteFile.sql does not have a "use somedatabase;" if it was exported with phpmyadmin, it probably has that, if it was exported with mysqldump it wont.


I am not sure if its the best way but I just spin up a new schema and restore the backup in to it, Dump the data I need and import that in to the production database.
I use the MYSQL work bench which makes it easier but the below steps can probably be reproduced at the command line
Create new MYSQL Schema
Import self-contained backup
Set "Target Schema" to the new empty database (.sql Dump must not contain schema creation code)
Restore backup
Dump table to csv and import it in to the production live database
Delete Restore Schema
To restore to a schema at the command line it looks like you use:
mysql -u <user name> -p <password> <database name> < sqlfilename.sql

mysql myisam bulk import from dump file is very slow

I'm using php to backup mysql database.
99% of this database is MyIsam table.
exec("mysqldump -u root -ppassword dbname | mysql -u root --password=password safe_dbname");
In this way, it is fast to back up but importing is very slow in php.
Is there any solution?

How to backup database entirely from local database to host database in laravel?

I'm using laravel and mysql as database, and I want to make a backup database in hosting with one click button in html, but I wonder what is the best query for them instead of query all data in all table with loop, then insert it one by one to host with loop. Thanks before

Use mysqldump
$ mysqldump -h <host> -u <user> -p<password> <database_name> > backup.sql
This will create a sql file backup.sql with all your data.
Note the missing space beween -p and <password>.
It's okay to give the password interactively (in which case, you'll have to skip the <password> part), but since you mentioned laravel in the question, I am assuming you want to code this and want it to be non-interactive.
EDIT:
Using code
Execute the command with exec()
$cmd = "mysqldump -h <host> -u <user> -p<password> <database_name> > backup.sql";
exec($cmd, $output, $return_value);

XAMPP (Windows) backup MySQL Database Automatically

I am trying to create a batch file in Windows to backup a MySQL Database, i have tried this:
C:\xampp\MySQL\bin\MySQLDump –u root –p database_name –result-file=”C:\Users\Administrator\Desktop\MySQLDump.sql”
but i get an error saying:
Got error: 1044: Access Denied for user ``#`localhost` to database `?u` when selecting the database

The solution to this problem/error was to use one of these mysqldump commands:
mysqldump --opt --lock-tables=false -u USER -p DBNAME > dump.sql
mysqldump --opt --single-transaction -u USER -p DBNAME > dump.sql
http://alvinalexander.com/mysql/mysql-error-1044-access-denied-for-user-using-lock-tables

Try this, it worked for me.
Don't forget to replace values inside {} as you need
C:\xampp\mysql\bin\mysqldump.exe -u{username} -p{passwrod} database > {/backuppath}.sql

Export table data into csv file using mysqldump

I want to export a table data into a csv file using mysqldump.
I want to make something like:
mysqldump --compact --no_create_info --tab=testing --fields-enclosed-by=\" --fields-terminated-by=, -uroot -proot mydatabase mytable
but i keep getting this error:
(Errcode: 13) when executing 'SELECT INTO OUTFILE'
I made my testing folder writable(I'm using Ubuntu as enviornment). Can somenone explain how to export a table in a CSV file, or how to modify my command shell in order to work? Thanks!

The trouble with all these INTO OUTFILE or --tab=tmpfile answers is that it requires running mysqldump on the same server as the MySQL server.
My solution was simply to use mysql (NOT mysqldump) with the -B parameter, inline the SELECT statement with -e, then massage the ASCII output with sed, and wind up with CSV including a header field row:
Example:
mysql -B -u username -ppassword database -h dbhost -e "SELECT * FROM accounts;" |sed "s/'/\'/;s/\t/\",\"/g;s/^/\"/;s/$/\"/;s/\n//g"

Add a > outfile.csv at the end of that one-liner, to get your CSV file.
