Mysql Database Wizard Download

My question is similar to this one but the crash happens later. I must interoperate an EF database-first model between SQL Server and MySQL. More specifically, my application had plain SQL queries fired to either SQL Server or MySQL according to connection string and configuration setting (DB_TYPE=MYSQL, etc.), having both databases with same structure and maintained together, so that each modification to one's schema was reapplied to the other.
Now I added EF support to the application using SQL Server database-first model. I must now let the application run on MySQL too. In order to verify that the old developer didn't leave something disaligned between the two DBMSes, I tried to Update model against database* and this time I selected the MySQL connection to my development database on localhost.
I have no idea why this works but I went in to my NuGet Package Manager and removed the MySql.Data.Entity (also checked dependencies which removed MySql.Data). I went into my .edmx and ran the 'Update model from database...' and everything worked.
It is a testament to the absolutely sub zero level of visual studio support, documentation, testing and basic development skill applied in the mysql dll's connector and documentation that I have spent the last 40 hrs of my waking life trying to put together a working model to get my application to connect with MySql 8.0.16 and to have a working entity framework wizard. At this point I am almost wishing I developed it using SQL Server.
I had a similar issue. After installing 'MySql.Data 6.9.9' and 'MySql.Data.Entity 6.9.9' Nuget packages, the wizard crashed after that screen. I attached a debugger to it and found it was caused by a null reference exception in MySql.Data.Entity.EF6.dll.
I am attempting to create an Entity Data Model using the wizard to reverse engineer an existing MySQL database. I get to the Choose Your Data Connection page of the wizard, select an existing MySQL connection and click Next, and the wizard crashes. Specifically, the dialog box just disappears without an error message or any trace. Every single time. Restarting VS or Windows does nothing.
Out of sheer luck and chance, I happened upon the same error.I am using VS 2015 with Entity Framework 6 as well. The error also happened as I was attempting to create the model from the database using EF reverse engineering existing connection.
As I commented to Lars Meldgård, uninstalling and reinstalling version 6.9.9 of Connector/Net got me one page further in the wizard. So I'll take that as a win. But I'm really confused why this worked. I was getting the problem on two different computers, my main desktop machine and my laptop. Similar configurations in Windows 10 with everything up to date, so were both corrupted? Not likely.
During the wizard install, the first screen is the license agreement, while the next screen deals with the System Environment. When I click on the Next button, I get the errors shown below. Why is the screen for configuring the database not showing up?
Use the MySQL Database Wizard interface to manage large amounts of information on your websites with a step-by-step guide. Many web-based applications (for example, bulletin boards, content management systems, and online retail shops) require database access.
The system limits the database name to 64 characters. However, due to the method that cPanel uses to store MySQL database names, each underscore character requires two characters of that limit. Therefore, if your hosting provider enabled database prefixing, the maximum length of the database name is 63 characters, which includes both the database prefix and the underscore character. Each additional underscore requires another two characters of that limit.
When you use the MySQL Database Wizard interface to add a user and a database, the system automatically grants the user access to the database. You do not need to use the Add User to Database feature in the MySQL Databases interface (Home >> Databases >> MySQL Databases).
The MySQL Database Wizard is another useful tool that allows you to create a MySQL database and user via a web interface. If you are about to install a PHP-MySQL application and you do not have a database already created for your script, this tool will guide you through all the steps needed to create such.
During the first step of your new database creation you will need to input the desired database name. Be advised that all cPanel databases are created with a prefix. This prefix represent your cPanel username and assures that your database name will be unique on the shared hosting environment even if you use a general database name such as test.
For example, if your cPanel user is "myuser" and you input "database" as your database name, the result will be a database called "myuser_database". You should take this under consideration when you configure your application or script to make sure that the correct settings are applied.
When you have the desired database name set, please click the Next Step button. During the next step of the process you will need to input your database username and password. This user will be the only one able to access the database. The username also follows the rule that its name is generated with a prefix, containing your cPanel username.
During the next step you should add privileges to your database user. Database user privileges sets the database actions that can be performed by this specific user. If you are about to setup and configure an application we recommend to apply All Privileges to make sure that your script will work properly.
When you are ready, click on the Next Step button on the bottom of the page. This will complete the process and you can now use your database name, user and password to install your application.
The detailed requirements and prerequisites for connecting to a MySQL database are beyond the scope of this Microsoft article. This article assumes that you already have MySQL client software installed and that you can already connect successfully to the target MySQL database. For more info, consult your MySQL database administrator or the MySQL documentation.
After you select .NET Framework Data Provider for MySQL on the Choose a Data Source or Choose a Destination page of the wizard, the page presents a grouped list of options for the provider. Many of these are unfriendly names and unfamiliar settings. Fortunately, you only have to provide a few pieces of information. You can ignore the default values for the other settings.
The connection options for this data provider are the same whether MySQL is your source or your destination. That is, the options you see are the same on both the Choose a Data Source and the Choose a Destination pages of the wizard.
You don't have to enter the connection string in the ConnectionString field of the list. After you enter individual values for the MySQL server name (Server) and login info, the wizard assembles the connection string from the individual properties and their values.
The connection options for this data provider and ODBC driver are the same whether MySQL is your source or your destination. That is, the options you see are the same on both the Choose a Data Source and the Choose a Destination pages of the wizard.
Enter the connection string in the ConnectionString field, or enter the DSN name in the Dsn field, on the Choose a Data Source or Choose a Destination page. After you enter the connection string, the wizard parses the string and displays the individual properties and their values in the list.
There are several ways to create a database on hosting. In this tutorial we will focus on the complex method using MySQL Database Wizard in cPanel. Not only will we make a database, but we will also create a user for it and give him access to the database.
Also, please note that cPanel will not allow you to review the database password in the future, you will be able only to change it. Therefore, you might want to keep it stored on file.
1. In cPanel, go to the MySQL Database Wizard interface (Databases >> MySQL Database Wizard). This interface will guide you through the process of creating the WHMCS database.
I know very little about database, brief search indicate that MariaDB is a fork of Mysql, which probably means I can use it the same way as I use Mysql for my websites before. But I still feel a little uneasy about this, I am planning to move some old sites to this new server, would some of them get broken because the programming is not campatible with MariaDB?
SQLite is the default database for Nextcloud Server and it is good only fortesting and lightweight single-user setups without client synchronization.Supported databases are MySQL, MariaDB, Oracle 11g, and PostgreSQL, and werecommend MySQL/MariaDB. Your database and PHPconnectors must be installed before you run the Installation Wizard. Whenyou install Nextcloud from packages all the necessary dependencies will besatisfied (see Installation on Linux for a detailed listing of requiredand optional PHP modules). You will need the root database login, or anyadministrator login , and then enter any name you want for your Nextcloud database.Be careful your administrator login needs to have the permissions to createand modify databases and they needs to have the permissions to grant permissionsto other users.
After you enter your root or administrator login for your database, theinstaller creates a special database user with privileges limited to theNextcloud database. Then Nextcloud needs only the special Nextcloud databaseuser, and drops the root dB login. This user is named for your Nextcloud adminuser, with an oc_ prefix, and then given a random password. The Nextclouddatabase user and password are written into config.php:
