MySQL 创建日期维度时出现语法错误 table？

Question

我从网站复制了一些 MySQL 代码来创建日期维度 table，并且我尝试在 PhpMyAdmin 的 MySQL 实例上运行它，但我收到一个错误。代码如下：

CREATE TABLE IF NOT EXISTS datedim  (
    date_id INT NOT NULL auto_increment,
    fulldate date,
    dayofmonth int,
    dayofyear int,
    dayofweek int,
    dayname varchar(10),
    monthnumber int,
    monthname varchar(10),
    year    int,
    quarter tinyint,
    PRIMARY KEY(date_id)
) ENGINE=InnoDB AUTO_INCREMENT=1000;


delimiter //

DROP PROCEDURE IF EXISTS datedimbuild;
CREATE PROCEDURE datedimbuild (p_start_date DATE, p_end_date DATE)
BEGIN
    DECLARE v_full_date DATE;

    DELETE FROM datedim;

    SET v_full_date = p_start_date;
    WHILE v_full_date < p_end_date DO

        INSERT INTO datedim (
            fulldate ,
            dayofmonth ,
            dayofyear ,
            dayofweek ,
            dayname ,
            monthnumber,
            monthname,
            year,
            quarter
        ) VALUES (
            v_full_date,
            DAYOFMONTH(v_full_date),
            DAYOFYEAR(v_full_date),
            DAYOFWEEK(v_full_date),
            DAYNAME(v_full_date),
            MONTH(v_full_date),
            MONTHNAME(v_full_date),
            YEAR(v_full_date),
            QUARTER(v_full_date)
        );

        SET v_full_date = DATE_ADD(v_full_date, INTERVAL 1 DAY);
    END WHILE;
END;

它发布于 2009 年，所以不知道问题出在哪里（也许是定界符？）。

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'CREATE PROCEDURE datedimbuild (p_start_date DATE, p_end_date DATE) BEGIN D' at line 2

我尝试将 phpmyadmin sql 查询中的分隔符更改为 // 并删除 sql 代码中的分隔符行，但现在我得到：

2 errors were found during analysis.

Unexpected beginning of statement. (near "p_start_date" at position 415)
Unrecognized statement type. (near "DATE" at position 428)

Answer 1

您已将分隔符更改为 //，因此您需要使用 // 而不是 ;

两者都

delimiter //

DROP PROCEDURE IF EXISTS datedimbuild//
CREATE PROCEDURE datedimbuild (p_start_date DATE, p_end_date DATE)
BEGIN
  ...

或

DROP PROCEDURE IF EXISTS datedimbuild;

delimiter //
CREATE PROCEDURE datedimbuild (p_start_date DATE, p_end_date DATE)
BEGIN
  ...
