全文搜索後，MySQL查詢鎖

Question

• MySQL的引擎：InnoDB的
• MySQL版本：31年6月5日

1.Run第一簡單的查詢

SELECT o.id 
FROM tbl_oper o 
WHERE o.id_oper_tip = 8 AND o.id_oper_naim = 6; 

結果：7行

2.R在同一個表未進行全文搜索

SELECT 
    o.id, 
    MATCH(o.full_text_search) AGAINST('7930' IN BOOLEAN MODE) 'match' 
FROM tbl_oper o 
WHERE 0 < MATCH(o.full_text_search) AGAINST('7930' IN BOOLEAN MODE) 

結果：6行（不管）

3.重複第一個查詢，結果：0行，但全文搜索還是回到6行

4.Queries沒有 「AND」 關鍵字正常工作：

SELECT o.id 
FROM tbl_oper o 
WHERE o.id_oper_tip = 8 

7行

個

SELECT o.id 
FROM tbl_oper o 
WHERE o.id_oper_naim = 6 

500+行

5，第一次查詢只能重啓後正常工作。爲什麼？

相同的結果查詢是從IDE，貝殼，PHP應用程序內

爲tbl_oper創建語句運行：

CREATE TABLE 'tbl_oper' (
    'id'    INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, 
    'id_oper_naim'  INT(10) UNSIGNED   DEFAULT NULL,

Answer 1

您是否嘗試修復表？

Answer 2

I還原型數據庫1個表，9行，3個索引。這是最小的設置重複錯誤; 沒有外鍵，只有索引。

CREATE TABLE `operations` (
    `id` int(10) unsigned NOT NULL AUTO_INCREMENT, 
    `name_id` int(10) unsigned DEFAULT NULL, 
    `type_id` int(10) unsigned DEFAULT NULL, 
    `description` text, 
    PRIMARY KEY (`id`), 
    KEY `name_id_idx` (`name_id`), 
    KEY `type_id_idx` (`type_id`), 
    FULLTEXT KEY `ft_idx` (`description`) 
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8 


id | name_id | type_id | description 
---+---------+---------+------------ 
1 | 2  | 3  | "hello world" 
2 | 3  | 1  | "pascal" 
3 | 3  | 1  | "geeen apple" 
4 | 6  | 8  | "deep hell" 
5 | 5  | 1  | NULL 
6 | 3  | 1  | NULL 
7 | 2  | 3  | NULL 
8 | 3  | 4  | NULL 
9 | 6  | 8  | NULL 

第一次查詢的工作，如果：

• 服務器重啓
• 重新編制任何索引
• 仍然單一行name_id = 6和type_id = 8

在版本5.6.31上檢查此錯誤5.6.34

升級到5.7.16解決了問題;
