I want to completely remove only YE\EZEENEXTGEN Database Engine. Not other server engines.
Use the below link to uninstall the instance. https://learn.microsoft.com/en-us/sql/sql-server/install/uninstall-an-existing-instance-of-sql-server-setup

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.
After I choose default DB with -
USE testDB
How can I cancel it and go back to work with no default DB ?
I use - MYSQL WORKBENCH version 5.4.14
The USE schema command is a convenience command to avoid having to explicitly qualify all identifiers that belong to a gvien schema. More informations in the MySQL docs.
A side note: I strongly recommend to always use the latest MySQL Workbench version. We are constantly fixing bugs and add new cool fetaures.
Firstly, my aim is to create a database to store statistical information about my wiki articles, that is derived using extensions that I have written for my MediaWiki server. Then via another extension on my server, I wish to access this secondary database and use the information to edit the output of the final article page.
I wanted to try and make a separate database to avoid introducing errors to the existing MediaWiki schema. Is this possible? I can't find any information about running an additional mySQL database alongside a MediaWiki installation.
I feel as though the better solution may be to add a table to the existing schema, but I'm not sure how to deal with the existing infrastructure without breaking it. I believe I can just use standard CREATE commands but mySQL is unfortunately not my strong point.
Thanks
Hope i understood your problem. say you have media wiki server or a mysql server running on port 3308 and you want to create another mysql instance.
Follow this step:
bkp my.cnf file
start first instance on port 3308
chnage my.cnf settings & make it run on 3307
start second instance of mysql
If you have good h/w,swap/RAM, you can easily create such 4-5 instances & all will be running good.
You can run a separate database along with the primary MediaWiki database. You just have to open a connection to it specifically using the PHP MySQL API.
Adding a new table to the existing database though is really easy and probably your best bet. You will be able to take advantage of the built-in database load balancing if your site ever gets big. To learn how to create a new table from an extension, check out this page of documentation.
I am looking for a solution or workaround in which MySQL will communicate with other Databases such as oracle, postgrey, MSSQL etc
Is there any way ?
I think that is not possible in native MySQL.
I was read about it, but I didn't try an experimental FEDERATED_ODBC engine:
http://capttofu.livejournal.com/3152.html
The official FEDERATED Storage Engine only allow to connect to another MySQL database servers.
Can we create a sql express-like database using MySql.
meaning: the database files can reside in the project's directory and can work on any machine having sql express installed.
Does MySql provide such a facility? and if so, how can this be done
thanks
Nope. This is not possible.
I've used Firebird SQL for that kind databases, especially coupled with the embedded engine.
Take a look at libmysqld. Basically, it lets you embed a MySQL server in a C/C++ program. Not sure how it works, as i've never used it. But it's supposedly a standard part of MySQL now, so it could be available to anyone that has MySQL installed.
I imagine you could have your own folder of tables and such, point the embedded server at it, and go.
