@davidwang88, thanks for the PR! We actually pull this grammar from https://github.com/Microsoft/vscode-mssql. If you make the PR there and the maintainers merge it then I can pull it into VS Code when I next update the language extensions. Otherwise the change will just overwritten when I update the grammar from https://github.com/Microsoft/vscode-mssql 😅

Hi! I forked the "vscode-mssql" project, and checked the content of file "syntaxes\SQL.plist" in it.
Then I checked "resources\app\extensions\sql\package.json" in "vscode" project, and found it seems that the content of file "resources\app\extensions\sql\language-configuration.json" is built and edited by human being instead of generated by script.

In fact, The comment lines at the bottom of "resources\app\extensions\sql\language-configuration.json" reveals it had beed edited by developer.
