Types

type FuncNode

type FuncNode struct {
	Param string
	Name  string
	Args  []Node
}

FuncNode represents a string function.

type ListNode

type ListNode struct {
	Nodes []Node
}

ListNode represents a list of nodes.

type Node

type Node interface {
	// contains filtered or unexported methods
}

Node is an element in the parse tree.

type TextNode

type TextNode struct {
	Value string
}

TextNode represents a string of text.

type Tree

type Tree struct {
	Root Node
	// contains filtered or unexported fields
}

Tree is the representation of a single parsed SQL statement.

func Parse

func Parse(buf string) (*Tree, error)

Parse parses the string and returns a Tree.

func (*Tree) Parse

func (t *Tree) Parse(buf string) (tree *Tree, err error)

Parse parses the string buffer to construct an ast representation for expansion.
