# This file is used by Sublime Text 3 to parse code using the SQL syntax. 
# 
# Below is unchanged from the default, except for a few modifications:
#   - Adjusted regex for alias (... AS Foo) to match the alias name as keyword.other.alias-name.sql
#   - Fixed regex for table/column name when the name is wraped in backticks or an asterisk (e.g. Foo.`Bar` or Foo.*)
