AQueryx is Interactive Query Tool which helps you to manipulate your SQL data easily. It can be used to view, search and modify your data using SQL commands, export data into text files (CSV, HTML, 'insert into ...' strings, fixed length text) and run long SQL scripts (e.g. conversions, imports). It uses XTG Grid component to display the result sets which gives you the ability to browse and search and order the results very easily. AQueryx has many comfortable features like table list view, three script and result panes which can be switched very easily, fast command execution by hitting Ctrl+Enter and more. It uses ODBC connectivity.
