TkSQL allows you to edit the tables of PostgreSQL and MySQL databases. You can use it from the shell prompt, specifying the name of a table, or an SQL satement, or just the name of a database. It has filter capabilities which are very easy to use. Two views are possible (tables and form) and both views can coexist. TkSQL can edit a join of two tables (limited to the first of such tables). Totals and subtotals can be done quickly, and displayed inline with the data or in a separate window. Queries can be created in no time and all working conditions can be saved at once (comprising subtotals, relative time constraints, layout, etc.). It also provides basic tools for creating tables.
