func (*Parser) Cast ¶

func (p *Parser) Cast(arg, typeName string) string

Cast returns a type cast expression. SQLite uses CAST(expr AS type) syntax.

func (*Parser) CommentSyntax ¶

func (p *Parser) CommentSyntax() source.CommentSyntax

func (*Parser) IsReservedKeyword ¶

func (p *Parser) IsReservedKeyword(s string) bool

IsReservedKeyword reports whether s is a keyword in SQLite; see https://sqlite.org/lang_keywords.html. The table lives in meyer, which transcribes it from SQLite's own aKeywordTable.

func (*Parser) Param ¶

func (p *Parser) Param(n int, numbered bool) string

Param returns the parameter placeholder for the given number. SQLite takes both a bare ? (the next index) and an explicit ?N, and they are not interchangeable — reordered ?N parameters bind by their numbers — so the one the author wrote is the one printed.

func (*Parser) Parse ¶

func (p *Parser) Parse(r io.Reader) ([]ast.Statement, error)

func (*Parser) ParseFile ¶

func (p *Parser) ParseFile(r io.Reader) (*ast.File, error)

ParseFile parses like Parse and also carries the file's comments, taken from the trivia meyer's single lexer pass produces alongside the tokens.

func (*Parser) QuoteIdent ¶

func (p *Parser) QuoteIdent(s string) string

QuoteIdent quotes an identifier when printing it bare would change what it names: the parser folds unquoted identifiers to lower case, so any name that is not already a plain lower-case identifier — or that collides with a keyword — only survives a parse round-trip inside double quotes.

func (*Parser) TypeName ¶

func (p *Parser) TypeName(ns, name string) string

TypeName returns the SQL type name for the given namespace and name.
