Oracle SQLDeveloper Autocomplete in Lowercase (How about Uppercase)

I'm using SQL Developer 2.1 (EA) from http://www.oracle.com/technology/software/products/sql/index21_EA1.html

.. which IMHO is much better than the 'current' version that I believe you're using. In the 2.1 version you can goto Tools > Preferences > Database > SQL Formatter > Oracle Formatting and hit 'Edit' to alter the behaviour of capitalisation effects.

It is my understanding, however, that in a Worksheet this will not 'autoformat' .. it only does this in procedures, packages, views, and triggers. (So you'll have to highligh, right-click, Format to do this in a worksheet).

I'm using SQL Developer 3.1.07 and you can change the case of the autocompleted table names by going to Tools > Preferences > Code Editor > Completion Insight there is an option for 'Change case as you type'.

For those using SQL Developer version 19.1.0.x, you can adjust upper-/lower-case identifiers and keywords in Tools -> Preferences -> Code Editor -> Format
