MySQL Workbench 6.2: Usability improvements and more

Direct Schema Tree Action Buttons

The schema tree in the SQL Editor now has some very convenient buttons for accessing the most used functions for each object type:

  • Table or Schema Inspector
  • Object structure editor
  • Table data browser/editor
  • Call Stored Procedure or Function

Format Note Objects in Diagrams

Note objects in diagrams can now be resized and have its contents automatically rearranged. You can also change style attributes like font, background color and text color.

MySQL Workbench 6.2: New Migration Source and Sync Feature

MS Access Migration

MS Access support was added to the Migration Wizard in MySQL Workbench 6.2, joining MS SQL Server, Sybase ASE, Sybase SQL Anywhere, PostgreSQL, SQLite and “Generic ODBC” as migration sources. You can read more about it in How-To: Guide to Database Migration from MS Access using MySQL Workbench.

Include Model Scripts in Forward Engineering and Synchronization

Workbench modeling has always supported attaching SQL script files to the model, usually for documentation/organization purposes. You can now include these attachments to the output script when performing forward engineering or synchronization.

MySQL Workbench 6.0: Model Synchronization Improvements

In MySQL Workbench 6.0, three longstanding issues related to model synchronization were addressed. In this post, we’ll cover how these issues can happen, the underlying cause and how to resolve them.

Model Synchronization

When you synchronize a model to a database, Workbench performs the following steps:

  1. Retrieve and reverse engineer the target schema from the database, to an internal representation that can be worked on by Workbench
  2. Compare the schema from the model with the corresponding schema from the database, object by object
  3. For each difference found, perform the corresponding action needed to change either the source or the target object, so they’re both looking the same. This may mean creating, altering or dropping objects in the database or updating the model to match the database. Because some of these actions can be destructive (such as when a table or column needs to be …

MySQL Workbench 6.0: What’s New

With the first beta of MySQL Workbench 6.0 just released, we’ll go through the list of improvements we’ve made since 5.2.47

New Home Screen

The Home screen went through a renovation and now has a modernized look. As part of the SQL Editor and Administration GUI unification, there’s now a single list for MySQL connections. Recently opened model files and other major features are also accessible from it.

You can organize different connections into “folders” by right clicking on a connection and selecting “Move to Group…” in the context menu.

New server connections can be added by clicking the + button next to the MySQL Connections heading. By clicking the Configure Remote Management… button in the new connection setup dialog, you can add server management capabilities to the connection. As before, SSH access with “sudo” is needed for remote management.

Know your data – and your numeric types.

Numeric types in MySQL have two varieties: - “precise” types such as INTEGER and DECIMAL; - the IEEE-standard floating point types FLOAT and DOUBLE. As a rule of thumb, the first group are for exact, “counted” quantities. The INTEGER types represent whole numbers, and DECIMAL represents “fixed point” decimal, with a preset number of places after the decimal point. Various widths of INTEGER are available in MySQL, from 8-bit TINYINT to 64-bit BIGINT. Calculations with integer types are fast, as they usually correspond to hardware register sizes. DECIMAL is commonly used for quantities like decimal currency where the number of digits of precision is known and fixed. For example, exactly counting pennies in two decimal digits. Computation with DECIMAL is slower than other types, but this is unlikely to impact most applications. In the other category are FLOAT and DOUBLE, which are the 32 and 64-bit IEEE standard types, which are usually …
