Question

MySQL引擎：InnoDB
MySql版本：5.6.31

1.运行第一个简单查询

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

结果：7行

2.在同一张桌子上运行全文搜索

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)

结果：6行（无论如何）

3.重复第一个查询，结果：0行，但全文搜索仍然返回6行

4.没有＆＃34; AND＆＃34;关键字正常工作：

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

7行

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

500+行

5.第一个查询仅在重启后才有效。为什么呢？

从IDE，shell，php-app

运行查询时的结果相同

为tbl_oper创建语句：

CREATE TABLE 'tbl_oper' (
    'id'                INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
    'id_oper_naim'      INT(10) UNSIGNED          DEFAULT NULL,
    'id_oper_tip'       INT(10) UNSIGNED          DEFAULT NULL,
    'num'               VARCHAR(20)               DEFAULT NULL,

Answer 1

你试过修表吗？

Answer 2

我将数据库缩减为1个表，9行，3个索引。这是重复bug的最小设置; 没有外键，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

首先查询工作如果：

服务器重启
重新索引任何索引
仍然是单行name_id = 6和type_id = 8

在版本5.6.31,5.6.34

上检查了此错误

升级到5.7.16已解决问题;

全文搜索后MySql查询锁定
