Types

type Kind 

type Kind uint8

Kind classifies a Tok. 

const (
	Text   Kind = iota // copied verbatim
	Param              // a positional '?'
	Named              // an @name; Text is the name
	Dollar             // a native $n; Text is the digits
)

type Tok 

type Tok struct {
	Kind Kind
	Text string
}

Tok is one token of a scanned fragment.

func Scan 

func Scan(sql string, d *dialect.Dialect) (toks []Tok, err error)

Scan splits sql into verbatim text and placeholders. A '?' or '@name' inside a string literal, quoted identifier, comment or PostgreSQL dollar-quoted string is text, as are the PostgreSQL operators ?| ?& @? @@ and @>. "??" yields a literal '?'. A native $n outside those is a Dollar token on every dialect, so the caller can bind it on PostgreSQL and reject it elsewhere.
