I'm new to mySQL and myphpadmin, but a few weeks ago I figured out how to create a database, tables, add relationships and insert/modify records...great! I've been creating coldfusion forms that access and update the database...perfect! But I go back in to myphpadmin one day last week and my database is GONE! The only databases there are "information_schema" and "test" (which is empty). My database, "hr_database" is gone! Crazy thing is (besides that), I can still use my ColdFusion forms to access and modify that database!
Anyway I can get it back in myphpadmin? If you all need more info, just let me know!
Thanks so much!

I think Fido is right. The user you're logging into phpmyadmin probably doesn't have rights to see that database. If you have root access, make sure to login with that. If not, use the same user your CF DSN uses.

I sort of have a heart attack of a problem. I had a non-root utility user in mysql that used to be able to see all the databases, tables, etc. on the mysql instance. The user was also able to insert records, delete records, create tables, etc. too. This user is used by scripts to edit records, or view the data as someone who's not root via phpmyadmin.
I don't know how Django fits into this or if it was even the cause but a contractor needed access to the db to work on their project we asked them to work on. They said they were using Django and needed to create some auth tables in the database (auth_group, auth_user, auth_user_groups, etc.)
However, after they added their tables for Django, that utility user can't see anything except the "information_schema" database.
Luckily, I checked using the root user in mysql and can see the databases but somehow, I still cant see the databases with the non-root user. I don't see anything that jumps out at me permissions-wise in the "user" table in mysql so I'm not sure how to fix this problem. I want to see what commands the contractor ran to get us into this situation to tell them not to do this again.
I was going to check the .mysql_history file in the unix root user directory but the funny thing is the file is dated from 3 weeks ago so it doesn't look like this will yield any info on what was run.
So, back to my original question, where can I see a history of mysql commands that were run on mysql so I can figure out what happened or what was run to get us into this funny situation?
I've searched for an answer to this and all I can seem to find are questions asking whether it is better to use multiple databases or multiple tables in a single database. This isn't my question though.
QUESTION 1.
I want to set up a new database alongside my current DB and don't know how. I want to give a user full admin access to DB2 without seeing DB1. This way I can host a friend's site and they can create and delete as many tables as they want without disturbing my own DB. I could also use it for demo sites that aren't secure and shouldn't exist inside my primary DB.
I figure I could do this pretty easily with a virtual machine and run a separate instance of MySQL but my resources are limited so that isn't really an option.
I'd like to set this up in one of 2 ways. I would prefer to have "server.example.com" host both DBs and open the proper DB based on user login. If not I could do it routing to server1.example.com and server2.example.com.
QUESTION 2.
If this isn't possible I'd like to know how to properly set up restricted access to a single DB in sequel pro. I have been messing around with it and so far prefer it to PHPMyAdmin. For some reason if I set up a new user with no permissions they have full access to my 'information_schema' and 'test' tables but can't create new tables. I don't want other users to access these tables though and I want them to be able to set up their own tables. I'd like to set it up so a new user can create a limited number of tables and only see and edit those tables. I can't seem to find information on this either.
Even if my first question is possible I'd like to know the answer to question 2. I've been searching for a long time and can't find reliable information anywhere. Maybe my brain is just tired...
You can set up multiple instances of mysql but for your situation you are better off creating different databases within the same instance.
You can create databases and then add users that only have access to manipulate the database they are given and nothing else.
Essentially the heirarchy is as follows:
Mysql (root or any other super user can see everything)
- Your DB
- Your Users
- Your tables/functions/Procedures/etc
- Their DB
- Their Users
- Their tables/functions/procedures/etc.
You basically separate the access for each, and in PHPMyAdmin it is very easy. The steps are:
Add Database )
Add User, restricting them to that database allowing only priveleges you want to give to that user and only to that database. (Guide here)
You can grant access to different database to different user using GRANT in MySQL.
https://dev.mysql.com/doc/refman/5.1/en/grant.html has the information you need.
The most simple you can do is
CREATE DATABASE db_for_user_a
CREATE DATABASE db_for_user_b
GRANT ALL PRIVILEGES ON db_for_user_a.* TO user_a IDENTIFIED BY 'user_a_s_password'
GRANT ALL PRIVILEGES ON db_for_user_b.* TO user_a IDENTIFIED BY 'user_b_s_password'
You are going to need to provide more information about your set up to answer this question of setting up multiple databases specifically.
Servers typically have methods to create multiple databases with software that is designed specifically to run on those platforms (Apache, and Windows server are a couple servers that can run software like WAMP or phpMyAdmin to manage these databases).
And in answer to the permissions: Yes, you can designate users that can have specific privileges on one, both, or neither of the databases. But, you can also set up table-specific roles and actions as well. This is more obvious with Microsoft's management studio though, where Mysql you may want to use something like Mysql Workbench initially.
On cPanel, for example, you can add a new database if your host allows it. On windows, you'll have to use other tools to set up a new database.
In answer to your first inquiry, each database requires its own connection, and there are database-wide operations that you can do such as migration and backups. A rule of thumb is to only keep entirely separate data in different databases, unless there is absolutely a reason to separate types of information into a different kind of database for efficiency. Typically, you do not relate data between different databases except for much more complex situations.
You can create separate databases and use them separately in sequel pro, I believe. Most platforms have an option to create a new db in the databases list.
Well I think I was confusing some stuff here. I apologize for that. I was calling databases 'tables'.
I was wanting to allow users to create new databases but not see the ones that others create. I think I can make this work by just limiting permissions and allowing users to access one or two databases.
It seems like PHPMyAdmin has some easier to use options than Sequel Pro. I've only briefly used it in the past but I'll give it another shot.
As for command line stuff, I love being able to work in command line but I don't know all the commands so it makes things generally difficult to figure out and the man pages weren't all that helpful.
Thank you for your answers and I'm sorry for my newbie questions.
I've spent all day trying to figure out how to properly set up MongooseIM to use ODBC with MySQL.
Here's my ejabberd.conf: http://pastebin.com/Lyptf4Jm
I can register a user with the command mongooseimctl register user domain.example.com password
And I can see that the password is indeed correct in the users table (though stored in plaintext, which I want to change if possible) but I can't connect from Pidgin. I get "Not Authorized".
This is only one in a list of issues I'm having with MongooseIM at the moment, but it's the most important one right now. Can anyone help or at least point me in the direction of a document detailing what needs to be done to set up MongooseIM to properly work with MySQL?
I'm looking into using CloudBees for some application prototyping. I am using free accounts right now, I am not paying any subscriptions at the moment.
The first step for me is to create a MySQL database to host my application's data. I've done so (and it was pretty easy!). I also use Liquibase to manage the database (I've started this work using local H2 databases for the pre-prototyping), and I've been able to construct everything as expected.
As part of checking whether liquibase created the tables, I brought up the MySQL database in NetBeans. And, it did function well. But I can also see other schemas as well as the schema I just created. They're all innocently named (test, test_6hob). But, I can see the tables and view their data.
My question is around the visibility of the data that's in the CloudBees database. Is the database created for the free accounts viewable to other people connecting to the same machine? Does this change if I use a paid account? Or is it more the nature of how the database was created? I can see other schemas (and their data) but I have no idea if other people can see mine? Is there a permissions-aspect I need to ensure I set? I've fairly ignorant with the inner-workings of MySQL.
While this is a prototype, were I to move into using CloudBees for production applications, I wouldn't want the data to be visible to anyone who happened to connect to the same database as my application. It's entirely possible that I'm missing something in this new cloud world. :)
Thanks for any info
All CloudBees MySQL databases are secured separately (although will be in shared instances unless you have a dedicated server) - they are not readable by any other account by default.
However, it is possible for the database owner to grant access to users from other accounts on that same database server if you really wanted to - even though it makes very little sense to do so (and your special user configuration will be lost during a failover).
So this is what has happened for the test databases that you can see - the database owner has opened up security on those databases / tables.
This question is probably off topic but i'll bite anyway. The database data is private to your account. Actual hardware/vm's maybe shared but the data/database is not.
I have a sql query done by someone. I cannot seem to see the table where query is reading from, but offline, the table is in the same db. The dbconfig is the same offline and online.
Is there any way I can find where the table is, or unhide if hidden.
Thanks Jean
This sounds like a permissions issue. If you're the database administrator, login as root to see all the tables that exist. (If you can't see it as root, it just plain doesn't exist.)
If you're not the database administrator, contact whoever is to get access.
you can try running the query "show full processlist;" which will show you what connections exist, what database they are connected to, and what query they are currently executing.
You can also turn on query logging by adding "log = /path/to/logfile" to the config file or "-l logfile" to the mysqld command line and watch the queries executed there, though note that this can be a performance killer.
Please post the query. Some points to consider -
Maybe you are not in the correct database. Change to that database & try again.
Maybe you don't have permissions to log into that DB. Your script has (thanks to correct username, password).
That's all I can think of for now. Post your query so answer can be more constructive...
Thanks issue solved.
[edit]
Sorry guys...
#pekka ofcourse, had to jot quickly to close the issue.
I was auditing couple of servers, and noticed that one particular table in a db was missing, but queries was fine. It was on one server, which had nothing to do with the db. I had root access, but could not see anything, but a test db.
Thanks all for your help, as you all have been. Every answer is equal to a correct answer, and I am unable to mark it correct. Therefore I have given an upvote for all.
Thanks again
