The diff on this is larger than in actuality because phpcbf needs to be ran.

Merging #162 will clear that up.

I have a field with a backtick in a mysql database (absolutely insane, I know, not my choice) - and found that I was breaking out of the identifier name.

This improves the quoting of of identifiers across the board.

  • Common SQL specifies a quote is quoted by doubling the quote, so a"b is quoted as "a""b"
  • MySQL specifies that a single backtick becomes a double backtick, so a`b is quoted as `a``b`
  • MS-SQL when using brackets only wants you to quote the closing brackets, so a[b] is quoted as a[b]]]

I changed Sqlite to target CommonSQL as it matches the behaviour - see: https://www.sqlite.org/lang_keywords.html

More than happy to make any requested changes. Let me know

I removed the phpcbf run b/c it was noise
