問題描述

這是我的表:

DROP TABLE IF EXISTS `tbl_comments`;
CREATE TABLE IF NOT EXISTS `tbl_comments` (
  `id` int(11) NOT NULL auto_increment,
  `topic_id` int(11) NOT NULL,
  `user_id` int(11) NOT NULL,
  `text` text NOT NULL,
  `create_dt` datetime NOT NULL,
  `update_dt` timestamp NULL default CURRENT_TIMESTAMP,
  PRIMARY KEY  (`id`),
  KEY `topic_id_2` (`topic_id`),
  KEY `user_id` (`user_id`),
  CONSTRAINT `tbl_comments_ibfk_2` FOREIGN KEY (`user_id`) REFERENCES `tbl_users` (`id`),
  CONSTRAINT `tbl_comments_ibfk_1` FOREIGN KEY (`topic_id`) REFERENCES `tbl_topics` (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;


DROP TABLE IF EXISTS `tbl_users`;
CREATE TABLE IF NOT EXISTS `tbl_users` (

  PRIMARY KEY  (`id`),
  UNIQUE KEY `user_username` (`username`),
  UNIQUE KEY `user_email` (`email`)
) ENGINE=InnoDB AUTO_INCREMENT=14 DEFAULT CHARSET=utf8;


DROP TABLE IF EXISTS `tbl_topics`;
CREATE TABLE IF NOT EXISTS `tbl_topics` (
  `id` int(11) NOT NULL auto_increment,

現(xiàn)在我嘗試導(dǎo)入時出現(xiàn)錯誤:#1005 - 無法創(chuàng)建表 'kobeco_yii.tbl_comments' (errno: 150)(詳細(xì)信息:Percona-XtraDB，支持事務(wù)、行級鎖定和外鍵)

now i have the error when i try to import: #1005 - Can't create table 'kobeco_yii.tbl_comments' (errno: 150) (Details: Percona-XtraDB, Supports transactions, row-level locking, and foreign keys )

推薦答案

您正在嘗試在其他表之前創(chuàng)建 tbl_comments.tbl_comments 需要表 tbl_users 和 tbl_topics 用于外鍵約束.

You're trying to create tbl_comments before your other tables. tbl_comments requires tables tbl_users and tbl_topics for foreign key constraints.

嘗試將 tbl_comments 的 CREATE TABLE 移到其他下方.

Try moving the CREATE TABLE for tbl_comments to below the others.
