In our last blog, we had a look at MySQL 8 and mentioned new features available here. However, some of those features are already in MariaDB and have been for a while. We will here compare database roles in both server dialects.

The Purpose of Database Roles

It’s common for numerous users within an organization to share the same database privileges. A role bundles a number of privileges together so that the DBA can set the privileges for a group of users all at once, rather than having to set each user’s privileges individually.  

With shared applications, it is not uncommon for multiple users to share the same user account. The drawback to this arrangement is that there is no way to see which actual user was responsible for which action.

Roles make managing this much easier. For example, there …

This new release of SQLyog primarily addresses a long-time concern by corporate users preferring to do a ‘silent installation’ over the corporate network. Even though ‘silent installation’ already was possible, every instance still had to be registered interactively from the workstation by every user. Now registration details can be applied on the command-line as well when doing a ‘silent install’. In addition to command-line this has been tested with a number of 3rd party softwares used by corporations for managing a centralized software repository and for centralized software management.

Changes as compared to MySQL GUI 12.4.3 include:

Features:

* Added command-line syntax for applying registration details when doing a ‘silent install’. You may refer …

SQLyog is a professional-grade GUI tool for the MySQL RDBMS. SQLyog is available for the Windows operating system starting from Windows XP/Windows 2003 to Windows 8/Server 2008 R2. It will also work under Linux, Unix and Mac OS X using the Wine environment. Moreover, a subset of SQLyog Enterprise/Ultimate functionalities are available with the free SQLyog Job Agent (SJA) for Linux as a native Linux utility. This makes it possible to specify and test ‘scheduled jobs’ on a Windows environment and port execution parameters seamlessly to a Linux environment.

Why Use a Database Administration Tool

Database administration tools provide a GUI/Web interface to automate database tasks like querying tables, find and replace operations, and any other task that you might want to run on a database. With respect to MySQL, it offers the free MySQL Workbench. Although it’s far more …

This maintenance release of SQLyog, MySQL GUI introduces a new feature – REGEX search in Object Browser – and adds a few bug fixes.

Changes as compared to MySQL GUI 12.4.1 include:

Important notice:

* The tunneler file for HTTP-tunnel has been updated with this release and must be replaced on the server.  Earlier HTTP-tunnel required PCRE-support in the server-side PHP-environment. Now it does not.

Features:

* Search function in Object Browser now supports regular expressions.

Bug Fixes:

* Fixed a rare connection failure using SSH-tunnel to specific BSD systems.
* Removed unnecessary virtual column check for older servers with no support for this.
* Fixed a crash when a …

This release introduces a new major feature – ‘read-only’ connections – as well as Kerberos authentication support and a few bug fixes.

Changes as compared to MySQL GUI 12.3.3 include:

Features:

* Added an option for defining a connection as ‘read-only’.  There is a checkbox in the connection settings and when checked the title bar will inform user about the ‘read-only’ state. In ‘read-only’ state statements that write cannot be executed. For more details please see note at the bottom.
* Added support for the MariaDB auth_gssapi (Kerberos) plugin. This plugin is available with the latest 3.0 (alpha) Connector/C from MariaDB. But there seems to  be a huge popular demand for this already, and we have backported it to the 2.3 connector version we use in SQLyog.  Note that support …

This release fixes two rare crashes and also we have upgraded the (MariaDB) C-connector to latest version (2.3.1). Most important this solves an issue when connecting to Amazon RDS using SSL. This was not possible before.

Changes as compared to MySQL GUI 12.2.5 include:

Bug Fixes:

* SQLyog was not able to connect to RDS instances using SSL encryption. Attempting to do so returned the error “Failed to connect to MySQL: SSL connection error: certificate verify failed”.
* After having a connection open for very long time, SQLyog could crash when closing this connection.
* Corrupted connection information in the ‘session restore’-database could cause a crash. We had one reproducible report of this, but please note that there is no indication that SQLyog itself caused the corruption. It may be due to a hardware error, for …

With SQLyog MySQL GUI 12.2.5, JSON comes to SQLyog. This is a new and major thing.  Also, Foreign Key management with NDB tables was added and the user- filter was improved in the User Manager. Additionally, some non-critical GUI bugs were fixed.

Changes as compared to MySQL GUI 12.2.4 include:

Features:

* Added basic support for the JSON datatype as of MySQL 5.7.8+ and MySQL Cluster 7.5.2+. The datatype is now available in the CREATE/ALTER TABLE dialog and JSON data will open in the BLOB-viewer. In the BLOB-viewer we have added validation that content is valid JSON. Also JSON-related keywords and functions are recognized in syntax highlighting and autocomplete. Also please see note at the bottom.
* SQLyog GUI now supports Foreign Key constraints between NDB tables for MySQL Cluster 7.3+.
* It is now possible to filter the users based on a string in the …

MySQL 5.6 proposes improved partition maintenance through "partition exchange". Even if not yet available, dbi services performed some tests on the MySQL Community Edition5.6.2 m5 release (still under Development).

MySQL Workbench provides several necessary tools in order to manage a MySQL environment. MySQL Workbench 5.2 is available for Windows, Mac and Linux platforms, it encapsulates three main functionalities:

1.    SQL Development: Allows connecting to existing databases and run SQL Queries, SQL scripts, edit data and manage database objects. This functionality replaces the ones previously provided by the Query Browser stand-alone application.

2.    Data Modeling: Helps to create and manage models, allows forward & reverse engineering and provides capability to compare and synchronize schemas

3.    Server Administration: Helps to configure a database server, to setup user accounts and browse status variables and server logs

Let’s have a look deeper in each of those features:
