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 (*Parser) Parse ¶
Parse parses a query string to raw ast.StmtNode. If charset or collation is "", default charset and collation will be used.
func (*Parser) ParseOneStmt ¶
ParseOneStmt parses a query and returns an ast.StmtNode. The query must have one statement, otherwise ErrSyntax is returned.
func (*Parser) SetSQLMode ¶
SetSQLMode sets the SQL mode for parser.
type Scanner ¶
type Scanner struct {
// contains filtered or unexported fields
}
Scanner implements the yyLexer interface.
func (*Scanner) Errorf ¶
Errorf tells scanner something is wrong. Scanner satisfies yyLexer interface which need this function.
func (*Scanner) Lex ¶
Lex returns a token and store the token value in v. Scanner satisfies yyLexer interface. 0 and invalid are special token id this function would return: return 0 tells parser that scanner meets EOF, return invalid tells parser that scanner meets illegal character.
func (*Scanner) SetSQLMode ¶
SetSQLMode sets the SQL mode for scanner.
