Types

type ParametersVisitor

type ParametersVisitor struct {
	// OrderedParameters are the passed named identifiers in the order that they have become numbered.
	// For example, if a query was SELECT * FROM tbl WHERE a = $a AND b = $b, the query would be rewritten
	// as SELECT * FROM tbl WHERE a = $1 AND b = $2, and OrderedParameters would be []string{"$a", "$b"}.
	OrderedParameters []string

	tree.Walker
	// contains filtered or unexported fields
}

ParametersVisitor visits the AST and replaces all bind parameters with numbered parameters.
