One of my db have tables around 10000(temporary use).
But what it has done that opening phpmyadmin become slow and my version is "2.6.0-pl2".
Because of this version I cannot use skip_db option of phpmyadmin.
So I decided to have a new user with permission to all database except one but I don't know how to do that.
So can someone tell me how to write grant to all db with skipping just one db ?
There is no need to create a user for this problem.
use show database command and you will get list of db.
In phpmyadmin version "2.6.0-pl2" , you can use show_db variable and set all tables there are your problem will be solved

When I try to log into MySQL via command line, keeps saying "unknown database 'magento2'"
Any ideas why? Tried as my username and root, getting the same message. If I can't log into mysql, how could I create a database to begin with of that name? So confused.
You should separate between your database application and a logical database. MySQL server is your database application / server.
When you're logging on to MySQL, you're choosing which logical database you would like to work with. A logical database is actually a container of objects such as tables, triggers, views, etc.
So when you see the error unknown database X, it's because you installed the MySQL server, but didn't create the logical database.
To see a list of all logical databases in your server, login to MySQL and run the command show databases;
To create your database, run the command create database magento2;
Now when you login to that database, it should be there and you can start creating your tables and query data from them.
I had the same issue and found that the database name was set in a cnf file. Perhaps you have something similar.
Running WAMP localhost server With php 5.6.18 and MySQL 5.7.11 In project that im working on now i need to get some column data form information_schema.COLUMNS table, but information_schema DB is completely empty - 0 rows for every table in this DB For additional information - I have like 10 differnet DB on this MySQL, some are imported some are made from scratch in phpmyadmin.So im completely lost - tried to google but no luck.Maybe i miss something essential and trivial like some configuration of MySQL?
Execute this query:
mysql> SHOW GRANTS;
This will show you that either you are not logging in as the user you intend to use, or that this user lacks permissions on the tables in question.
In this case, the user may have no permissions at all. MySQL has a special permission called USAGE, which may seem slightly deceptively named if you aren't familiar with what it means. It means you can "use" the server -- that is, you can log in. But that is all it means. If you possess only the USAGE ON *.* privilege, this means you have permission to log in to the server, but no permissions on anything else.
The information_schema is integrated with the permissions system. You can't see information about database objects for which you don't have permissions. An empty information_schema.columns table suggests a permissions issue for the user you are using to connect to the server.
Sometimes this may be issue when you copy and paste the database's folders in mysql folder. Don't copy that way. The best way to export the databases using "export" command in "phpmyadmin" or use "mysqldump" command in mysql command line client to copy the data or export data from one to another.It will generate "yourdata.sql" file at the last , You can import that data using "export command in "phpmyadmin" . In your method is successful for "MyISAM" database driver in mysql. Modern mysql servers default database driver is "InnoDB" and it not success in when copy the database data folder on to another machine. If you have copy of previous copy of the databases from the old machine, try to export the "yourdata.sql" file using export method in "phpmyadmin" web interface.
I faced same problem when I transfer/shifted my mysql folder to other location.
And configured DB to point Mysql folder accordingly.
However, Information_schema was not getting updated though rest DB queries were running fine.I could't find proper solution but the way around was from mysql editor (like workbench) do inspect schema.
You will get an option in bottom to 'Information Outdated' and then click on Analyze table. You will find that Information_schema start calculating correct size and other details.
Hello Stackoverflow,
I was trying to connect to my MySQL database through Coda 2. I connected, created a database called 'database1' (for example), then I tried to create a table called 'user', but I get this error:
MySQL said: Table 'user' is read only
I was surprised because it had worked previously with other databases long time ago. I went to my xampp files, //xampp/mysql/data/database1/ and then I found out that user.ibd is there alone. So I first tried to change the properties of the files by disabling read-only. The problem is that when I did that, close the properties windows, and opened again I would get the read-only check box on. So I gave up on that. So I said ok, I will just create the database from my server instead. So I when to phpmyadmin, I see that database1 is created but there is no table called 'user'. So I try to create a table and I get this error:
#1813 - Tablespace for table '`database1`.`user`' exists. Please DISCARD the tablespace before IMPORT.
I then I found out I cannot even do much with phpmyadmin from my server. I tried reinstalling xampp, but it was impossible for me to remove the origianal because it was "already" in use. Please help me and thank you!
EDIT: I can apparently create databases but not tables. Just to clear that up.
You can try using CLI and logged into mysql and create a new database and a table. If it's working, there's something wrong with your phpmyadmin not mysql. Make sure you logged in as the same user (whom have root privileges) when creating the database and table.
I 've re-installed mysql, uninstalled MAMP.
So currently I should only have one version of mysql.
I've done the following:
Installed phpmyadmin
Created a database
I try to import data to it, but the file is too big so I do it via the command line. But there I dont see my newly created database, furthermore I see less databases.
If I do show databases; on the command it shows:
information_schema
test
It doesnt show my newly created Database and it doesn`t show other databases that were pre-installed, these are the databases that I see on phpmyadmin:
information_schema
mysql
performance_schema
test
myBBDD->the one I just created and I was looking for to import data via command-line
It seems I have two versions of mysql, but if I stop mysql via command line, I then can't access phpmyadmin so I guess it's the same one, but for some reason I can't access the same databases.
If you could throw me a bone on this? Im completely lost.
To install mysql and phpmyadmin I've followed this tutorial
[EDIT]
I tried to delete test and it did dissapear from the command-line too, so it is the same version of MySql, so it must be a permission issue... still investigating
Thanks.
Sounds like you have MAMP's version of MySQL and a standalone MySQL. See this answer:
Access MAMP's MySQL from Terminal
Just had the same issue, in my case it turned out to be that I wasn't logging in as the correct user.
In the command line, instead of running just mysql, try running mysql -u root -p (replace "root" with whatever user you used in phpMyAdmin to set the databases up). You should then be able to type in the password. Check show databases; again.
Just noticed that user Grasshopper in a previous answers' comments was suggesting exactly this, hopefully this will help someone anyway by spelling it out.
I am very sure that i didn't delete my database and noone else sits on my machine. Then how did i my database get deleted automatically? I had 10 tables in it :(. Infact 2 databases got deleted automatically. They are not being shown in mysql query browser. How can i recover my databases back? Is there any query which will help to show the logs to see if the delete schema command was actually fired in mysql? I am very much frustrated. Please help. The last time i saw these database alive was before 2 weeks and today they are no more.
could be you are looking at them with a different user credentials that does not have sufficient privileges to see them?
What tool are you using to view them? command line, phpmyadmin etc?
Yes there are logs you can go through see here
Your database is not deleted from MySQL. You would have set your own user and password in user table when you created these tables. However the when You open my SQL it takes root as the user by default and password as NULL. So to fix it and to see your database and tables you need to set your username and password in config file of MySql.
Example:- If your username and password is XYZ you need to set them as below in config file(config.inc).
path for this file would be:-C:\wamp\apps\phpmyadmin4.1.14 (depending on the version you have installed)
$cfg['Servers'][$i]['user'] = 'XYZ';
$cfg['Servers'][$i]['password'] = 'XYZ';
We had similar problem where we lost all the tables of the database but the database remains as it is in the mysql. The problem and the solution is as follows:
Check where you have installed your MYSQL/XAMPP/WAMP
Check whether you have all the permissions to install the MYSQL/XAMPP at the
place where you have installed your XAMPP/MYSQL on your desktop/server.
The solutions is simple, just re-install your XAMPP/MYSQL on your desktop/any other location where you have permission to install.
Your will not get this problem in future.
Please do not forget to check your error logs and take necessary actions after checking logs daily.
