siqqel is a simple and lightweight framework which allows you to execute MySQL queries directly from your browser (by transforming them into JSON calls to a backend script), displaying the results of your queries within the structure of the calling HTML document. To issue a query and have its results displayed in a table of your HTML document, you simply put an SQL statement into the "sql" attribute of a <table> element and it will be executed when you open the HTML document in your browser. Your browser will wrap the SQL statement into a JSON call, and this call will be issued to a backend script on your server, which in turn issues the statement against your database server and returns the result set back to your browser. Your browser will display the result set in the according table. If you hover your mouse over the table, a "reload" icon will be displayed, allowing you to re-issue the SQL statement without the need to reload the whole page.
