sql - 为什么这个 MySQL Create Table 语句会失败？

Question

使用 mySQLAdmin 工具，我尝试创建一个表。该工具生成 SQL 语句，然后重新打印“无法创建表”，但没有其他线索表明它是什么错误!

在这里:

CREATE TABLE `C121535_vubridge`.`Products` (
  `pr_ID` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
  `pr_Name` VARCHAR(45) NOT NULL,
  `pr_Type` VARCHAR(2) NOT NULL COMMENT 'H=Hand Series V=VuBridge software E=Event Subs S=Sponsoring',
  `pr_AuthorID` INTEGER UNSIGNED COMMENT '= m_ID (for Bridge Hand Series',
  `pr_SponsorID` INTEGER UNSIGNED NOT NULL,
  `pr_DateCreation` DATETIME NOT NULL,
  `pr_Price` FLOAT NOT NULL,
  `pr_DescriptionText` TEXT,
  `pr_Description` VARCHAR(245),
  PRIMARY KEY (`pr_ID`),
  CONSTRAINT `FK_prAuthor` FOREIGN KEY `FK_prAuthor` (`pr_AuthorID`)
    REFERENCES `Members` (`m_ID`)
    ON DELETE SET NULL
    ON UPDATE NO ACTION,
  CONSTRAINT `FK_Sponsor` FOREIGN KEY `FK_Sponsor` (`pr_SponsorID`)
    REFERENCES `Members` (`m_ID`)
    ON DELETE SET NULL
    ON UPDATE NO ACTION
) ENGINE = InnoDB;

有人可以帮忙吗？

如果我省略外键引用，CREATE TABLE 对我有用:

CREATE TABLE `Products` (
 `pr_ID` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
 `pr_Name` VARCHAR(45) NOT NULL,
 `pr_Type` VARCHAR(2) NOT NULL COMMENT 'H=Hand Series V=VuBridge software E=Event Subs S=Sponsoring',
 `pr_AuthorID` INTEGER UNSIGNED COMMENT '= m_ID (for Bridge Hand Series',
 `pr_SponsorID` INTEGER UNSIGNED NOT NULL,
 `pr_DateCreation` DATETIME NOT NULL,
 `pr_Price` FLOAT NOT NULL,
 `pr_DescriptionText` TEXT,
 `pr_Description` VARCHAR(245),
 PRIMARY KEY (`pr_ID`)
)

...所以我倾向于相信 C121535_vubridge.MEMBERS 还不存在。 C121535_vubridge.MEMBERS 需要在运行 PRODUCTS 表的 CREATE TABLE 语句之前创建。
