Special Aspects of Sphinx SE Support

At the moment, dbForge Studio for MySQL allows you to create a connection to Sphinx Search Engine. Due to technical restrictions, a warning message appears in some cases. The reason the message appears is because, there is no possibility to define that the connection happens to  Sphinx SE. We requested the Sphinx SE developers team to fix this problem.

 

When the warning message appears?

Case 1: When you create a connection to Sphinx Search Engine, the message appears for the first time.

Case 2: The same message appears when you create a new SQL document. It appears only once and doesn’t repeat for other new SQL documents.

Case 3: The message appears when you click a Sphinx SE connection in Database Explorer.

In any of these cases, just click OK, and continue your work.

How To: Convert a Database from Microsoft Access to MySQL

Enhanced Entity Framework Spatials support for Oracle, MySQL and PostgreSQL

Entity Framework v5 and v6 support spatial data types. They are represented as two DbGeometry and DbGeography data types from System.Data.Entity.dll in .NET Framework 4.5 (Entity Framework 5) or from EntityFramework.dll (Entity Framework 6). We have already supported Entity Framework Spatials for Oracle database (see Using Entity Framework Spatials with Oracle Spatial and SharpMap). In the new versions of our providers we have improved Entity Framework Spatials support for Oracle and added spatials support for MySQL and PostgreSQL.

MySQL WorkBench Worthy Alternative – dbForge Studio for MySQL

Did you know that dbForge Studio for MySQL is a great alternative to MySQL Workbench? In case you have used MySQL Workbench in the past, or consider using it now, you might want to take a closer look at dbForge Studio for MySQL, to make sure you pick wisely the tool that will meet your requirements the best.

Every single year the software industry introduces new DBMSs which allow developers to achieve goals and objectives more efficiently. However, in order to benefit from all the features provided by the modern DBMS, you should define which one is more suitable for team’s needs.

Today we are going to draw a parallel between two similar products, that allow performing numerous tasks in MySQL environment. Both of them are specialized visual database design tools for MySQL databases. These products are MySQL Workbench 5.2.47, and it’s alternative — dbForge Studio for MySQL 6.0. (more…)

Adapting Diagram File to Another Database

Some of our users have faced the situation when they need to change the connection details of the existing Database Diagram file.

Let’s assume the situation when you have several databases with identical schemas which are only located on different MySQL servers and you have created a database model that was saved in a Database Diagram file. Now, you want to avoid redesigning the database model from scratch and only reassign the existing database model to another MySQL server. (more…)

Using MySQL Full-Text Search in Entity Framework

MySQL database supports an advanced functionality of full-text search (FTS) and full-text indexing described comprehensively in the documentation:

Workaround for ‘Authentication failed’ Issue When Connecting through HTTP Tunnel

Some of our users have encountered problems with establishing a connection over the tunnel.php script despite the fact that the tunnel.php script is installed correctly. The following error message occurs:

‘Can’t connect to MySQL server on ‘your.sitename.com’ (10061): Authentication failed.’

The problem appears to be with cached proxy servers and will be fixed in one of the next builds of our product.

Currently it can be fixed by replacing the dbforgemysql.exe.config file, that can be found in dbForge Studio for MySQL installation folder, with the attached one.

Mind data modifications via Data Editor in dbForge Studio for MySQL

Since one of our users has encountered a problem when modifying data via Data Editor, we decided to bring such a situation to our users’ attention.

Let’s assume you have the following table:

Data-Editor-1

Let’s execute the following query in the SQL document:

Now if you change any of the values of the first record in Data Editor, the changes will be applied to all records of the original table that have ‘DName’ = ‘Research’ and ‘loc’ = ‘Dallas’. (more…)

MySQL Debugging Methods Overview

Introduction
Debugging SQL code is a very important task these days. Unfortunately not all database servers support this feature. And MySQL is one of such servers. In spite of its wide feature set, debugging is not implemented in it. So the problem is that MySQL provides no API functionalities for code debugging. But the necessity to debug SQL code does not disappear and becomes more and more important each year. Some companies that develop tools to access data of MySQL server databases create their own debuggers that solve this problem to some extent.

Now we will consider the types of debuggers that can be implemented for MySQL server and principles of their work.
