Types

type Parser

type Parser struct {
	// contains filtered or unexported fields
}

Parser represents a parser instance. Some temporary objects are stored in it to reduce object allocation during Parse function.

func New

func New() *Parser

New returns a Parser object.

func (*Parser) Parse

func (parser *Parser) Parse(sql, charset, collation string) ([]ast.StmtNode, error)

Parse parses a query string to raw ast.StmtNode. If charset or collation is "", default charset and collation will be used.

func (*Parser) ParseOneStmt

func (parser *Parser) ParseOneStmt(sql, charset, collation string) (ast.StmtNode, error)

ParseOneStmt parses a query and returns an ast.StmtNode. The query must have one statement, otherwise ErrSyntax is returned.
