javascript autocompletion for DSL. (e.g.: SQL)

I want to give the user a web-page where he can type some simple SQL.

select * from myTable.

What I would like is to have the autocompletion area to help typing:

• sel

• [selECT]

• select * f

• [select * fROM]

• select * from

• [s开发者_JAVA技巧elect * fROM column1]
• [select * fROM column2]
• ...

Anybody can suggest if there is a nice open source library for this ?

I am not really interested in the SQL (I will have to parse a DSL) I am more interested on a powerful autocompletion text area widget.

This is a good jQuery auto-completion widget:

• jQuery/Autocomplete

Or, if you're more apt to hack something together yourself, Ordered list has an excellent write-up using a string matching algorithm ported from the excellent Quicksilver app (for the mac) :

• Live Search with Quicksilver Style

I have left this unanswered for a while. I am afraid it's fair to saythat there is not an autocompletion widget as described in my question.
