deltasql 1.8.1 has search query management as new feature

deltasql is a database versioning software and a script collection management tool.

The newest release 1.8.1 easies life for users who do lot of searches among scripts.
When users do search, the query is stored and listed. Users can click on the lists
'Last 10 Searches', 'Top 10 Searches'. They can flag a query as favorite, if they think
they will use it more often. Queries are automatically named with the criteria used
but users can rename the search query at their wish.

People who use deltasql as script collection tool, or to store a log of all queries
they run in a day will find this feature very useful.

deltasql on a Raspberry Pi

In the forum, there are instructions on how to install deltasql server on a Raspberri Pi 3:
The Raspberry Pi consumes only about 5W of power, running it through the year means a lot of savings compared to a normal server which consumes about 500W of power.

This means deltasql server runs on the Apache and mySQL, which in turn run on an ARM microprocessor. In other words: it is possible to install deltasql also on your cell phone :-)

1.6.3: tools to create and manage SQL scripts

deltasql 1.6.3 ships with two new tools which help to create SQL scripts based on exported files in comma separated value format (.csv). They are useful when managing third party applications which require configuration via GUI, or generally when customers send data to be loaded into the managed application.

The two tools support creation of INSERT scripts, and of INSERT,UPDATE,DELETE scripts based on .csv exported from your SQL client. This in case your SQL client does not have an SQL export feature, or if you want to record configurations changes on big applications mantained and developed by a third party. In such case, you would export the db table before doing the changes as .csv, and after doing it. The provided tool will generate automatically an SQL script with the changes, the script can then be submitted to deltasql in the usual way.... read more

1.6.2: intelligent branch selection :-)

deltasql 1.6.2 ships with logic to select only the branches valid for a given project. This is used when submitting or editing scripts. When synchronizing, only valid tags/branches are shown in the synchronization form. The three listboxes of the synchronization form adapt dynamically, as done with the Freepascal deltaclient. The feature is achieved with AJAX technology. These two features help to reduce the amount of human errors when using deltasql in a complicated environment with many branches and tags.... read more
