interval(start: Token, end: Token): String
Get all the text which between the given start and end tokens.
Get all the text which between the given start and end tokens. When we need to extract everything between two tokens including all spaces we should use this method instead of defined a named Antlr4 rule for .*?, which somehow parse "a b" -> "ab" in some cases

toExprAlias(ctx: ParseTree): String
Normalizes the expression parser tree to a SQL string which will be used to generate the expression alias.
Normalizes the expression parser tree to a SQL string which will be used to generate the expression alias. In particular, it concatenates terminal nodes of the tree and upper casts keywords and numeric literals.
