qub is a SQL editor that keeps the query at the centre of the window and everything else a keystroke away. It connects to PostgreSQL, MySQL/MariaDB, SQLite, Oracle, Firebird and ODBC at the same time, with passwords kept in the OS credential store rather than on disk.
The same result set opens as a grid, a chart, a per-column profile, a pivot table, a query plan, a set of data-quality checks or a diff against an earlier run. Completion knows the columns of the tables actually in scope, queries take named and positional parameters, and exports go out as CSV, TSV, JSON, Excel, Markdown or SQL INSERTs without being truncated to what the grid happens to be showing.
