Ask HN: Best Interactive Environment for SQL?

What's, for you, the best interactive environment for crafting SQL queries around here?

Things I'm wondering about:

* basic syntax help / autoindent

* red underline for indicating errors

* function autocomplete

* table and field autocomplete

* partial results streaming

* progress indicators

* table exploration (looking at a table catalog etc.)

* "workbench" where you can save multiple queries

* link to visualization tools

* link off to more powerful statistical analysis tools
