I have imported data into tables in mysql workbench. And I have clicked apply and saved it. But when I shut down my laptop, all of the data has disappeared. my data lost. What should I do to solve it?
maybe it was because of this
thank you
This happens when are conflicts because you used the options:
Include Model...
or
Import > Reverse Engineer MYSQL Create Script...
The only solution is to make EER Diagram again.

I have a problem when I backup my database from old server to the new one. Both run Ubuntu. The difference is the old database is using phpmyadmin 1.6.3 and the new one is 5.7.21. I lost some tables but it appear in the sidebar. Can anyone describe to me what is going on with my db? Here is the screenshot.
to be clear, here is the screenshot of my old database phpmyadmin interface.
You may try stop and start the mysqld service.
If the error still exists then back up the database file and drop it then import again to a newly created database.

I've been working on a project for a couple of months now with a few other developers and it has got to the point where we all have different changes to the DB we are working with, but all of the changes are local, meaning the server is out of sync with all of our local changes.
What is the best way to handle this? At the moment I tried to basically export my database from my local PC with phpMyAdmin and import that .sql file into the database on the server but as some of the tables already exist on the server it just gives out an error...
Would I have broken my database on the server by trying to import that sql file?
What do I do?
Ok so here's what I would do in your position...
Use this tool: http://www.clevercomponents.com/downloads/dbc/dbcdownload.asp
With the database compare tool, it should identify the differences in structure between two databases.
This generates an SQL file which will alter the target (your server) database to match the master (your local).
Always backup your target database before attempting something like this, just in case it goes wrong.
I've just installed MySql Workbench 6.0.09 on recommendation. The main reason was to copy my Wordpress database which is stored in MySql.
I'm using the import/export function with a single file, however it doesn't seem to populate the new schema whether I create it before hand or let the process create it.
I've read somewhere that this cross schema copy doesn't work in older versions, but I'm unsure whether this is still the case, i'm doing something wrong, or there is a permissions issue. It seems unlikely that I'm doing something wrong as there is literally a few clicks to deal with.
Anyone advise?
From the discussion above I conclude this question is about creating a duplicate of an existing database using MySQL Workbench. There are several possible approaches for this scenario:
Createa a dump of your source server using the Data Export feature in MySQL Workbench:
. Then restore that dump on the target machine (via Data Import/Restore).
Do a quick an easy shot by using Schema Transfer Wizard. See menu -> Database -> Schema Transfer Wizard...
Start a normal MySQL to MySQL migration using the Migration Wizard under the same menu item. This would also allow to migrate to different MySQL versions.
I didn't find an answer to this however, I did work out a solution.
1) I took a backup of the existing database.
2) I edited the script produced by the backup. I edited the database name on 2 lines at the top of the script then ran it.
I was having a website at a hosting while taking the backup I took the backup of whole mysql by mistake which includes databases of all my other websites also.
So now the problem is I want to extract that particular database from complete sql file?
Is there any procedure to do it or can we import that complete dump file into a mysql. So that later I can export that particular database after importing it to MySQL.
Please help me or suggest me how to do it.
Thank You.

This should help.
If the size of the schemas in your backup file that you do not want to restore are not that big and there aren't that many other schemas in there, your best bet would probably be to just restore the entire backup and then do a backup of just your schema. One easy way to backup just your schema is to use MySQL Workbench. If you run into problems getting setup or doing the backup you might want to check this little write up that walks you through installation and performing a backup.
I'm working on a group project and my partner sent me a .mwb file so I could take a look at what they did for the ER diagram, but she can't figure out how to send a .sql file for the database itself (at least I think those are .sql files). How do you save and send a database to someone? I am trying to test the database by writing some queries, but I don't know how to do that if all I can look at is the Diagram. Thanks for any help.
MySQL work bench can definitely do this for you.
here is one link where you have some screenshots too : Back up and restore MySQL databases using MySQL Workbench
It shows how to do both export and import of a database backup.
