Question

----- MYSQL代码-----

CREATE DEFINER=`uativiza_v3`@`localhost` PROCEDURE `Procedure name`(IN p_processno INT)
BEGIN
  DECLARE EXIT HANDLER FOR SQLEXCEPTION 
  BEGIN
    CALL offline_logger (p_processno,'Exception caught -----Exception caught : RollingBack!') ;
    ROLLBACK ;
  END ;
  START TRANSACTION ;
        Insert into table1 select * from table2
 COMMIT ;
END$$

DELIMITER ;

-摘要如果在插入时发生任何异常，则上述过程调用offline_logger过程

以上代码我必须迁移到postgresql中。那么如何在PostgreSQL中处理Handler（Exception）

Answer 1

这将大致翻译为

CREATE PROCEDURE procedure_name(IN p_processno integer)
   LANGUAGE plpgsql AS
$$BEGIN
   INSERT INTO table1
      SELECT * FROM table2;
EXCEPTION
   WHEN OTHERS THEN
      CALL offline_logger(
              p_processno,
              'Exception caught -----Exception caught : RollingBack!'
           );
END;$$;

INSERT会在发生异常时自动回滚。

什么是EXIT HANDLER FOR SQLEXCEPTION（postgresql）的替代方法
