type QuestionMarkExpr 

type QuestionMarkExpr struct {

type Scanner 

type Scanner struct {
}

Scanner represents state and options used for multiple calls to NormalizeQuery

func (*Scanner) NormalizeQuery 

func (n *Scanner) NormalizeQuery(q string) string

NormalizeQuery converts an sql statement into a normalized version (downcased, with all string/numeric literals replaced with ?). It most definitely does not validate that a query is syntactically correct.
