Introduction While performing database integration tests, things went south, and I ended up with more than 15 (fifteen) temporary PostgreSQL test databases. I use OmniDB, an open-source application for managing databases. Version (3.0.2b) of OmniDB does not have an option for selecting and dropping multiple databases. To drop a database in OmniDB, you right-click on a database, select Drop Database from the context menu, run the query to drop the database, and finally close the query window.
Introduction Extensible Markup Language (XML) has been in existence for more than two decades. XML is a markup language for encoding documents in a format that is both human and machine readable. In XML, you define your own custom tags, elements and attributes to meet your specific needs. XML is case sensitive, allows comments and hierarchy is important. An XML file is a text file and can be opened with any text editor.
Introduction The DROP TABLE command in PostgreSQL removes a table definition, all data and indexes of a table from a database. DROP TABLE will fail if the table has other objects that depend on it like views and foreign key definitions. The command will also fail and display a table does not exist message if the table being dropped does not exist. PostgreSQL does not have a drop all tables command and you have to define your own way of performing this task.
