=== 錯誤 1170: 在鍵規格中使用 BLOB/TEXT 欄位且沒有鍵長 === | |||
情況 | |||
* 嘗試建立新表格時的 SQL 語法 | |||
<pre> | |||
DROP TABLE IF EXISTS `my_table`; | |||
/*!40101 SET @saved_cs_client = @@character_set_client */; | |||
/*!40101 SET character_set_client = utf8 */; | |||
CREATE TABLE `my_table` ( | |||
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, | |||
`title` varchar(500) COLLATE utf8mb4_unicode_ci DEFAULT NULL, | |||
`url` text COLLATE utf8mb4_unicode_ci NOT NULL, | |||
`status` tinyint(2) unsigned NOT NULL DEFAULT 1, | |||
PRIMARY KEY (`job_id`), | |||
UNIQUE KEY `url` (`url`) USING HASH | |||
) ENGINE=InnoDB AUTO_INCREMENT=3573 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci; | |||
/*!40101 SET character_set_client = @saved_cs_client */; | |||
</pre> | |||
解決方案：在鍵規格中使用 BLOB/TEXT 欄位並指定鍵長，例如 {{kbd | key=`url`(500)}} | |||
<pre> | |||
DROP TABLE IF EXISTS `my_table`; | |||
/*!40101 SET @saved_cs_client = @@character_set_client */; | |||
/*!40101 SET character_set_client = utf8 */; | |||
CREATE TABLE `my_table` ( | |||
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, | |||
`title` varchar(500) COLLATE utf8mb4_unicode_ci DEFAULT NULL, | |||
`url` text COLLATE utf8mb4_unicode_ci NOT NULL, | |||
`status` tinyint(2) unsigned NOT NULL DEFAULT 1, | |||
PRIMARY KEY (`id`), | |||
UNIQUE KEY `url` (`url`(500)) | |||
) ENGINE=InnoDB AUTO_INCREMENT=3573 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci; | |||
/*!40101 SET character_set_client = @saved_cs_client */; | |||
