Overview ¶
Package sqllex is the SQL lexer shared by the plugin sandbox's table scope check and the organisation query scoper. It splits a statement into words, quoted identifiers, string literals and punctuation; it is not a parser.

Kind byte // 'w' word, 'q' quoted identifier, 's' string literal, 'p' punctuation
Text string // word: upper case; punctuation: the character
