Programmers and DBAs looking for a way to run ad hoc SQL statements against DB2/400, SQL Server, MySQL, and PostgreSQL databases may want to check out a new tool from Stonewall Technologies called iHOC Query. The Windows-based program was initially developed with iSeries users in mind, but was quickly adapted to support other databases as well. The GUI makes switching between different database connections as simple as choosing a server from a drop-down box. Users can run SQL statements, filter their results, generate statistics with a built-in statistics generator, and export results in a variety of formats, including comma- and tab-delineated files, as a Microsoft DataSet XML file, or in the MySQL dump file format. iSeries users are also treated to an extra iHOC Query feature called the Database Explorer, which enables users to see the catalog structure of the database. Version 1.0.2131.14788 may include unspecified updates, enhancements, or bug fixes.
