Variables ¶
var ( // ErrSyntax returns for sql syntax error. ErrSyntax = terror.ClassParser.New(codeErrSyntax, mysql.MySQLErrName[mysql.ErrSyntax]) // ErrParse returns for sql parse error. ErrParse = terror.ClassParser.New(codeErrParse, mysql.MySQLErrName[mysql.ErrParse]) // SpecFieldPattern special result field pattern SpecFieldPattern = regexp.MustCompile(`(\/\*!(M?[0-9]{5,6})?|\*\/)`) )
Functions ¶
func ParseErrorWith ¶
ParseErrorWith returns "You have a syntax error near..." error message compatible with mysql.
func TrimComment ¶
TrimComment trim comment for special comment code of MySQL.
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 ¶
func (parser *Parser) Parse(sql, charset, collation string) (stmt []ast.StmtNode, warns []error, err 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 ¶
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) AppendError ¶ added in v1.0.2
AppendError sets error into scanner. Scanner satisfies yyLexer interface which need this function.
func (*Scanner) EnableWindowFunc ¶ added in v1.0.2
func (s *Scanner) EnableWindowFunc()
EnableWindowFunc enables the scanner to recognize the keywords of window function.
func (*Scanner) Errorf ¶
Errorf tells scanner something is wrong. Scanner satisfies yyLexer interface which need this function.
func (*Scanner) GetSQLMode ¶
GetSQLMode return the SQL mode of scanner.
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.
