databases not visible in mysql workbench sidebar - mysql

It started with installation of wampserver for php, before that I had already running MySQL server 5.7 with all databases properly showing in the side schema panel. When I launched MySQL server after installation of wampserver 5.7.14, the password for root was overridden and no database except sys is showing. Also I found another user (mysql.sys) has been created (found in Users and Privileges). Then I looked for databases in path "ProgramData\MySQL\MySQL Server 5.7\Data", all databases are present in the folder (thank god they are not deleted). Problem is now for my website I get this error:
"Unable to update database to match the current model because there are pending changes and automatic migration is disabled. Either write the pending model changes to a code-based migration or enable automatic migration. Set DbMigrationsConfiguration.AutomaticMigrationsEnabled to true to enable automatic migration"
Exception Details: System.Data.Entity.Migrations.Infrastructure.AutomaticMigrationsDisabledException: Unable to update database to match the current model because there are pending changes and automatic migration is disabled. Either write the pending model changes to a code-based migration or enable automatic migration. Set DbMigrationsConfiguration.AutomaticMigrationsEnabled to true to enable automatic migration.
I know this is not related to migrations because my database already exists but I don't know how to solve the problem that MySQL can see the databases in its "ProgramData\MySQL\MySQL Server 5.7\Data" again.

When you installed WAMPServer on a system that already had a MYSQL Server instance installed on it, you created a second MySQL Server instance. See your service you will have one called wampmysqld or wampmysqld64 and another called MYSQL.
Now, whichever service you start first will be the MySQL Server that Workbench, or anything else is talking to. And you will only see the databases that this MySQL Server instance knows about.
Correct Solution:
Stop WAMPServer
Start the MYSQL installed with Workbench
Backup all YOUR databases, NOT the ones created by MySQL like mysql, sys, information_schema, performance_schema
Stop this MYSQL Server.
Uninstall this MySQL Server
Start WAMPServer
Restore your databases to this MySQL Server instance
All should start working as expected now.
Connect your Workbench to WAMPServers MySQL Server

Update
Did a robust workaround, though not very suggestible but database is now accessible in MySQL workbench. Though I'm having the same error when opening the website on local web server. One thing that I did not mention before that environment is Windows based. what I did is copied database from the ProgramData MySQL path to "..\wamp64\bin\mysql\mysql5.7.14\data" path and refreshed schema in workbench. Any advice why I'm still having problem in web server.

MySQL server not started after installed Apache Cassandra

I am trying to work with multiple database with single project. I have successfully integrated my project with MySQL database, but after installing Cassandra (by DataStax 3.9.0) I face problem to connect with MySQL database.
I got error
can't connect to MySQL server on '127.0.0.1' (10061)
I have reverted the process and uninstalled Cassandra but there are same issue at time of starting MySQL. Also in the Services TAB in Control Panel, I do not get any option to start MYSQL Service Manually and the Startup type is "Automatic".
Please check if mysql database is already running or not.If running you can stop start with the database you want to work.

How can we view the databases/tables created in phpmyadmin in the MySQL workbench schemas section?

How can we view the databases/tables created in phpmyadmin in the MySQL workbench schemas section? In my case the database created in the phpmyadmin are not reflected in workbench(v-6.3) and mysql server v-5.7.12.How can I check that the phpmyadmin used is reflecting the correct workbench.
I am running the phpmyadmin locally (XAMPP 5.6.20-0) and I am using Mac OS X El-capitan. Is the import only option copy all databases/tables created in phpmyadmin into MySQL and visa versa?Please advice
As long as MySQL Workbench and phpMyAdmin are connected to the same MySQL instance, any changes made in one program should immediately be visible from the other. You might be restricted if you're connecting as different, non-administrative users who doesn't have access to the same databases.
From each program (MySQL Workbench and phpMyAdmin), issue the STATUS; SQL command and compare the host and port or socket. If they don't match, you would seem to have more than one MySQL installed on your machine.
The fact that you have specifically mentioned installing MySQL server and XAMPP makes this highly likely; XAMPP comes with its own version of MySQL server and you should pick one to access from both client programs to minimize confusion.

Connecting my MySQL databases to phpMyAdmin

I am running Mac OS 10.10.2. I have recently been educating myself about php and SQL in order to create an online database application for my employer. However, I have been unable to load up my MySQL databases in phpMyAdmin. I have tried following some advice from this forum, but no answers seem to solve my issue.
I installed MySQLWorkbench (Ver. 6.2.4.12437) as well as XAMPP (Ver. 5.6.3-0), and was using phpMyAdmin to have a play around and better understand what I was getting myself into. I then found one of those follow-the-bouncing-ball type teaching websites which advised me to download and install the MySQL community server (Currently running Ver. 5.6.23)
As instructed, I was learning SQL commands through Terminal and built up some databases/tables this way. I decided I wanted to jump into phpMyAdmin where I felt it'd be easier to continue my work. At first XAMPP was unable to turn on the servers which I overcame by uninstalling and reinstalling. Then I was getting a #2002 error when trying to access phpMyAdmin. I tinkered with config files and put in details relating to my localhost MySQL server (Or at least I assume as much).
I was able to get back into phpMyAdmin finally, but my databases made through terminal are not there.
phpMyAdmin shows: cdcol (the example database), information_schema, mysql, performance_schema, phpmyadmin, and test.
If I open terminal and punch in 'mysql' then 'SHOW DATABASES;' it only lists: information_schema.
If I open terminal and punch in 'mysql' with username 'root' and my password, then 'SHOW DATABASES;' it lists: information_schema, mysql, performance_schema, my tutorial/learning database, and my business database. I dropped the test database from here. THESE are what I want to bring up in phpMyAdmin.
I can only guess that I haven't got it configured properly to access this last mysql server, but I can't determine where I am going wrong. If anyone can shed some light on this, that'd be greatly appreciated.
It appears as if you have two MySQL instances; one from the XAMPP and also the MySQL Community Server that you installed yourself.
The "M" of XAMPP is for MySQL, so yes usually it runs its own MySQL server instance. That's sort of the point of the packaged kit, so you don't have to worry about having any of your own applications installed. In theory it should be no problem to stop the XAMPP MySQL instance and instead use your other one, but may require tweaking some configuration files and is probably not supported. If you can make it work, I don't see a reason why it would be a problem, though.
My suggestion is to either use the complete XAMPP stack or roll your own installation rather than mix and match.

Mysql Table corrupted after restarting PC

I am working on Symfony2 Project and am beginner in symfony Framework. I am using XAMPP as webserver. Everything is working properly until system restarts. When I restart my computer the tables of mysql database using by symfony project corrupts automatically.
I am using windows 7 professional 32bit OS.so, is there any problem in mysql?
MySQL tables can become corrupt for several reasons, such as hardware
failure, operating system bugs, viruses and bugs in MySQL. hMailServer
itself does not cause corrupt MySQL tables. hMailServer communicates
with MySQL over TCP/IP using a standardized language.
There's nothing in this language that can cause corrupt tables.
If a MySQL table becomes corrupt, you need to repair it. Note that repairing a corrupt MySQL table may lead to loss of data. It's therefore important to create a backup of your system.
How do you know whether a table is corrupt?
Examine the hMailServer error log. If you see a lot of Error while executing SQL statement-messages, then it's likely that one or more of your tables are corrupt. Feel free to ask in the forum if you're unsure.
Step 1: Determine MySQL password
If you are using an external version of MySQL, you should already know your MySQL password.
If you are using the built-in MySQL version that comes with hMailServer, you might not know your password. To determine it, follow these steps:
Run the script hMailServer/Addons/Utilities/DecryptBlowfish.vbs.
Enter your main hMailServer Administrator password. This is the
password you specified during the installation when you first
installed hMailServer. Click OK.
Open up hMailserver.ini, located in your Windows directory or
hMailServer bin directory.
Copy the database password from hMailServer.ini to the "Enter
encrypted password" dialog. In hMailServer.ini, you should see a
line looking like this: [Database]
...
password=c85dae3cb73394ab
In this example, c85dae3cb73394ab is the encrypted password.
Click OK in DecryptBlowfish to view your password
DecryptBlowfish will now show your password. Either keep the dialog open or memorize the password.
Step 2: Connect to the server
To be able to repair your table, you need to connect to the MySQL server using a MySQL client. You can use SQLyog for this.
Download and install SQLyog
Create a new connection.
Enter the connection information for your MySQL server. If you are
using the built-in server, you should enter hostname: localhost,
user:root, password:password from DecryptBlowfish, port:3307
Click Connect to connect to the database server
Step 3: Repair the table
Follow these steps to run the SQL statement to repair the table.
In the tree to the left, click on the hmailserver database.
The hMailServer database will now be active.
In the right part of the SQLyog window, click on the Query tab.
Enter REPAIR TABLE tablename, for example, REPAIR TABLE hm_messages.
Click on the Execute Current Query button in the toolbar (or select
Edit->Execute Query->Execute current query or press F5).
MySQL should now repair the table. After the table has been repaired, restart the MySQL and than the hMailServer service. Depending on what table is corrupt, a restart of the services may not be required, but we recommend that you always do it.

How to show different databases MySQL workbench?

I downloaded MySQL, and installed it correctly.
When I started the MySQL workbench it shows me these databases (I don't remember all of them):
sakila
test
world
It is ok, they are work, I can access them with no problems. But later I installed xampp, after that when start MySQL workbench it shows me different databases:
cdcol
phpmyadmin
test
webauth
I can't access the previous databases.
How to switch between them?, or
view them all?
Not sure whether xampp uninstalled your first server, but it is more likely that its installation changed the default MySQL TCP/IP port (3306). Maybe both servers try to run on the same port (which doesn't work) and one failed to start (in this case the first installation).
So what you need is to make each server run on its own port. You can use MySQL Workbench to make the necessary change. However first you need to check if still both servers are installed. Do you have 2 MySQL services running? Switch off one of them and connect with MySQL to the running server. If that works shut this down and run the other service. Connect again with MySQL but this time go to the admin section, config file, and change the port to e.g. 3307. Save and restart the server (all within WB possible). Now you should be able to run both servers at the same time (provided the first one runs still on the default port). Create a second connection and server instance in WB so that you can access one server at 3306 and the other at 3307
If there's only one MySQL service entry then xamp has removed the previous installation and you must install it again if you really need two servers.
