I am totally new to databases. I would like to create a database; I am going to make a small project which is going to use DB. I am going to use Maria DB as it is totally free for commercial use.
The question is: Can I use MySQL workbench program to create a database and then transform/change it to MariaDB?
From my experience -- Sure, you can use MySQL Workbench with MariaDB.
However, I have tried basic functionalities only, like queries, schema design etc. Not sure about compatibility of advanced features.
So my experiences are, yes you can use MySQL Workbench for MariaDB database designs.
However I needed to change the "Default Target MySQL Version" to 5.7.
This can be done by going to: Edit->Preferences in the menu. And finally to Modeling->MySQL.
Since the latest MySQL version, v8.x, the SQL statements are not compatible with MariaDB statements (like creating an index). MariabDB creating an index on a table:
INDEX `fk_rsg_sub_level_rsg_top_level1_idx` (`rgs_top_level_id` ASC)
vs
MySQL:
INDEX `fk_rsg_sub_level_rsg_top_level1_idx` (`rgs_top_level_id` ASC) VISIBLE
MariaDB can't handle this VISIBLE keyword in this example. Using an old MySQL Version, MySQL Workbench will forward engineer a compatible MariaDB SQL file.
Currently (Oct 2019) the generated SQL_MODE output is still compatible with MariaDB. Just like InnoDB, which is also preferred when using MariaDB in most cases.
Just to list a few other options:
MySQL Workbench
Heidi Sql
SQLyog
No.
The latest version of Workbench 8.0 is not supported in MySQL.
Yes, although connecting to view existing database on a remote MariaDB server will crash the current client (6.3.10). I use it mainly to deploy database models and that works fine, even on remote servers.
I just deployed to a MariaDB 10.3 server with that client and it worked fine, see screenshot.

Hello, people, I'd appreciate it if you could assist me with this problem. I'm using workbench and mysql, and I have a few schemata (databases) in my sql. However, when I log in using Mysql Query Browser, it doesn't show my schemata (databases), but it does when I use workbench.
MySQL Query Browser was the first visual DB query tool from MySQL. Since a decade or so it has been replaced by MySQL Workbench and does not support servers beyond 4.x (IIRC).
Ultimately, I want to learn MariaDB. I’ve found that there are hundreds more resources for learning MySQL than for MariaDB. My assumption is that everything I learn from a MySQL book will also apply to MariaDB since it’s a drop-in replacement for MySQL.
From the MariaDB website:
For all practical purposes, MariaDB is a binary drop in replacement of the same MySQL version (for example MySQL 5.1 -> MariaDB 5.1, MariaDB 5.2 & MariaDB 5.3 are compatible. MySQL 5.5 will be compatible with MariaDB 5.5).
Will I be able to use MySQL books to prepare for learning MariaDB or will they be useless to me if what I really want to learn is MariaDB?
If you take care about the few differences and incompatibilities (very few, mariadb starts from the same codebase than MySQL), you should have no problem using a resources from one DB and applying them to the other DB.
Even more so if you are mostly focusing in SQL syntax.
You don't really need to care about the differences, unless you are a very advanced user. MariaDB can replace MySQL with every application I know. Some MySQL 5.6 optimizations are not in MariaDB, but much more MariaDB optimizations are not in MySQL.
I've scoured the MySql website to see if they have compatibility listings for MySQL Workbench, but have not found anything. Does anyone know if 6.0.x can connect to 5.5.x databases? I'd rather not install and then have to roll back.
MySQL Workbench can connect to most MySQL server versions, but that is probably not the primary question. You should rather ask what minimum version it can work with. MySQL Workbench requires at least MySQL 5.0 and can work with any MySQL server after that (including the new 5.7). Some features like authentication plugin or performance schema support require higher server versions, though.
I've instaled MySQL workbench in Windows 7 64bit. Unfortunately, I'm facing problems:
In the Object Browser, when I click on my DB and right click on tables to create one, I can not insert any column (disabled) and therefore, can not insert tables. check this:
Can not create table in MySQL workbench 5.2.40
I can create table from the EER model. But even though, I faced problems when tried to connect my Java application to this database.
MySQL and Java: table doesn't exist
I have searched, and not sure from this, some of what I found is that workbench have probelms with Windows 7 - 64 bit (any idea if this is correct??). The only version I found was for 68, it installed successfully but I'm having probems.
I want to downlod MySQL server but before that: Will Mysql Server give me the same features that the workbench does? I need to work with GUI (insert, delete, update,..etc).
EDIT:
Also, the table I added using the EER are not visible in the Object browser. I only can see the schema in the Object browser without any table underneath it.
MySQL Workbench is a MySQL Server GUI. The two are different products. MySQL Workbench requires a MySQL Server connection for most tasks (except for data modeling). This reliance on a MySQL connection is clearer in the latest version of MySQL Workbench (6.1) than it was in 5.2.
MySql Workbench and MySql Server both are completely different things. MySql Server is basically a database and MySql workbench is a GUI or graphical management tool which helps us interact with MySql server database.
Similarly, SQL Server Management Studio is the graphical management tool for SQL Server.
Both are for manipulate the structure, queries and function, procedure, etc....
In Both you can Use DML and DDL
If you ask me I love Server even if you can create really cool designs on workbench, but basically you can do the same in both (insert, delete, update,..etc and more)
So it's up to you, I think MySQL server is a little bit lighter that Workbench, but if you want to, try it both.
Workbench looks like more friendly
I am doing a research regarding migrating from MySQL to MariaDB and viceversa.
As it seems, the first part should be easy and not complicated as stated here: MariaDB versus MySQL - Compatibility
It is the "viceversa" part that botters me: MariaDB -> MySQL. I just could not find anything useful about this topic.
Can anyone help? Any advice, hint? Are there complications migrating from MariaDB back to MySQL?
Thank you so much.
If there is someone who should ever take care of migrating from MariaDB to MySQL, it would be Oracle. As Oracle pretends MariaDB does not exist (company politics-policies) , it also does not provide the possibility to migrate (which does not bother me personally, because being on MariaDB team I'd prefer people to chose it and stay there :)
Having said all the above, the migration should be straightforward, provided you do not use special features (so, no storage engines besides MyISAM/Innodb). You shutdown MariaDB, you save the data directory, remove MariaDB, install MySQL, copy the saved data directory back. In the worst case you'd need to remove parameters from my.ini/my.cnf that are not recognized by MySQL.
The point I'm trying to make is since persistent data formats for most commonly used storage engines are compatible, no data migration is required (at least not yet:)
It's very easy ton migrate Mysql to MariaDB (so, no storage engines besides MyISAM/Innodb).
Backup your database
Stop mysql server
Set your repositorie
(http://downloads.mariadb.org/mariadb/repositories/), it's depend on your linux stack.
Execute commande line to install MariaDB.
But now migrate MariaDB to Mysql is more difficult. I have no solution yet for this operation. Since my last try i have crashed my server...
