SQL Delta for MySQL (SDMY) is an easy to use schema and data compare tool for MySQL databases.
Compare your development database schema with your production schema by scanning for the slightest difference between the two. Then with just a few clicks and in no time generate a deployment script ready to synchronize your target database. SQL Delta can even run the deployment script.
The data compare function makes searching for data changes between MySQL tables simple and efficient. Just like Schema compare the Data compare can generate a deployment script for synchronizing your data.
Features in general
Includes Schema Compare, Data Compare plus Schema and Data View
Within a single application compare and sync the structure of two databases and compare the data from two databases. Plus SQL Delta can display the schema and data just like common database editors.
Supports MySQL Version 5.0 and higher
SQL Delta re-formats the source to match the target when comparing databases on different servers making the display more consistent
and generating less false positives compare results.
Execute multiple projects simultaneously
Run two or more projects side by side in separate tabs, whether it's two schema compare projects on completely separate servers
or a schema compare and data compare project on the same server.
Because each process is run in separate threads you can be reviewing or even running an
update script while waiting for other compare processes to complete.
Project elements shown in Tabs
From editing a project, to displaying the schema compare results and then displaying the schema update script.
Each process is shown in its own tab. The usability of the application is much simpler and consistent.
Even using touch is easier with the new interface.
Generates a single synchronize script ready for deployment
SQL Delta generates a single script including all of the selected objects and in the case of sub-selection can
automatically include dependent objects.
An example of dependent scripting is where only a single table difference has been selected for scripting and that table contains a Foreign Key. If the related table has changed then SQL Delta automatically includes update script for the related table to ensure any synchronizing script will deploy without errors.
Run change script from SQL Delta
There is no need to use another tool to run your update script, just click execute within SQL Delta
and the target database is updated.
Of course if you wish you can save the change scripts and use them in other tools,
perhaps you don't have immediate access to the remote server.
One or more filters can be applied to object loading.
An example is where a database has objects that are temporary (all begin with temp_) and not required to be compared.
Simply add a schema filter temp_ and these objects will not be loaded and compared.
The same can be done for columns within a table.
On Completion Events
Each project can execute a series of events once the initial project execution has completed.
The event could be to run another project, save a snapshot of the database schema,
run a report or execute the change script.
On Completion events are an easier way of defining tasks that were available only in command line processing.
Command line processing is still available however now uses On Completion events.
Built-in dependency management
SQL Delta uses both its own analysis of dependent items to determine object dependency for scripting.
Dependencies are important to reduce script failures and while these failures may not be catastrophic
(a second compare can be run and the database re-scripted) they do generally prevent a script from running in a single instance.
Perhaps a foreign key must be dropped before other changes are made or a function relies on a table.
SQL Delta without the html display is a single executable that less than 20mb.
There are no DLLs and no requirements to register COM, .NET or other services.
Subject to licensing, SQL Delta could be part of an in-house application without the complex installs and other requirements of other tools.
The html display for reports requires some third party DLLS.
