Question

我无法将存储过程从Firebird转换为MySQL。

这是我现有的Firebird代码：

CREATE OR ALTER PROCEDURE GET_EOMONTH (
    selectmonth integer,
    selectyear integer)
returns (
    lastdate timestamp)
as
declare variable vmonth integer;
declare variable vyear integer;
begin
  VMONTH = selectmonth+1;
  VYEAR = selectyear;
  if (VMONTH=13) then
    BEGIN
      vmonth = 1;
      vyear =  selectyear + 1;
    END


  LASTDATE = CAST(VMONTH || '/1/' || VYEAR AS DATE) - 1;
  /* Procedure Text */
  suspend;
end^

然后我将上面的代码修改为：

CREATE PROCEDURE GET_EOMONTH (
    selectmonth integer,
    selectyear integer)
returns (
    lastdate timestamp)
as
declare variable vmonth integer;
declare variable vyear integer;
begin
  VMONTH = selectmonth+1;
  VYEAR = selectyear;
  if (VMONTH=13) then
    BEGIN
      vmonth = 1;
      vyear =  selectyear + 1;
    END


  LASTDATE = CAST(VMONTH || '/1/' || VYEAR AS DATE) - 1;
  /* Procedure Text */
  suspend;
end

从上面的代码我得到以下错误：

您的SQL语法有错误;检查手册对应于您的MySQL服务器版本，以便使用正确的语法靠近＆＃39;（ lastdate timestamp）as declare variable vmonth integer＆＃39;在第4行* /

我再次修改了这个：

DELIMITER $$
CREATE PROCEDURE GET_EOMONTH (
    IN selectmonth INT,
    IN selectyear INT,
     OUT LASTDATE VARCHAR(100))
BEGIN
DECLARE VMONTH INT;
DECLARE VYEAR INT;
  SET VMONTH = selectmonth+1;
  SET VYEAR = selectyear;
  IF (VMONTH=13) THEN
    BEGIN
      SET VMONTH = 1;
      SET VYEAR =  selectyear + 1;
    END;
   END IF;
  SET LASTDATE = CAST(VMONTH || '/1/' || VYEAR AS DATE) - 1;
  SELECT @LASTDATE;
END
END$$

但是，错误说：

SQL错误（1064）：您的SQL语法中有错误;检查手册，对应右边的MySQL服务器版本要在＆＃39; END＆＃39;附近使用的语法在第19行

请建议。

现在我修改这样的代码：

DELIMITER $$
CREATE PROCEDURE GET_EOMONTH (
    IN selectmonth INT,
    IN selectyear INT,
     OUT LASTDATE VARCHAR(100))
BEGIN
DECLARE VMONTH INT;
DECLARE VYEAR INT;
  SET VMONTH = selectmonth+1;
  SET VYEAR = selectyear;
  IF (VMONTH=13) THEN
    BEGIN
      SET VMONTH = 1;
      SET VYEAR =  selectyear + 1;
    END;
   END IF;
  SET LASTDATE = str_to_date(CONCAT(VYEAR, "-", VMONTH, "-1"), '%y/%m/%d') -1;
  SELECT @LASTDATE;
END$$
DELIMITER ;

它有效。
