Here you go, this will uppercase the preceding SQL keyword when you press Space:
keybinding:
{ "keys": [" "], "command": "upper_case_previous_item_and_insert_space",
"context":
[
{ "key": "selector", "operator": "equal", "operand": "source.sql", "match_all": true },
{ "key": "selection_empty", "operator": "equal", "operand": true, "match_all": true },
{ "key": "scope_before_cursor", "operator": "equal", "operand": "keyword", "match_all": true },
//{ "key": "preceding_text", "operator": "regex_match", "operand": "[a-z]+$", "match_all": true },
]
},

@addons_zz I just fixed a “small” bug, that would make ST hang if you are typing in a blank file 
i.e. open a new tab, set syntax to SQL and type select and press Space and it would make ST unresponsive - oops!
In other news, it is a shame that plugins can do that…

I released a new version 1.1:
"""
Automatically set all SQL keywords to upper case after the space keystroke.
Originally created by `kingkeith` on `https://forum.sublimetext.com/t/automatically-set-sql-keywords-to-upper-case/23760`.
Change log:
1.1 - Added multiple scopes support for the SQL's `support` scope on the `sublime.keymap` file.
1.0 - Initial release by `kingkeith`.
"""
import sublime
import sublime_plugin
class UpperCasePreviousItemAndInsertSpaceCommand( sublime_plugin.TextCommand ):
"""
Called each time the space is pressed to process the preceding keyword.
Set the space key bind to:

"context":

the normal way of specifying multiple scopes is just using a scope selector, i.e. in the keybindings:
{ "key": "scope_before_cursor", "operator": "equal", "operand": "keyword | support", "match_all": true },
that way, the plugin code doesn’t even have to change, and it doesn’t change the semantics of the operand such that an array is needed/expected by the plugin code.
