在MySQL数据库中快速搜索字符串？

使用FULLTEXT搜索来快速搜索字符串。让我们首先创建一个表-

mysql> create table DemoTable1554
   -> (
   -> Title text
   -> );

这是创建全文本搜索的查询-

mysql> create fulltext index faster_title on DemoTable1554(Title);
Records: 0  Duplicates: 0  Warnings: 1

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable1554 values('John is working on MySQL database');
mysql> insert into DemoTable1554 values('Adam Smith is working on Java language');
mysql> insert into DemoTable1554 values('John smith is working on Python Language');

使用select语句显示表中的所有记录-

mysql> select * from DemoTable1554;

这将产生以下输出-

+------------------------------------------+
| Title                                    |
+------------------------------------------+
| John is working on MySQL database        |
| Adam Smith is working on Java language   |
| John smith is working on Python Language |
+------------------------------------------+
3 rows in set (0.00 sec)

以下是在MySQL数据库中快速搜索字符串的查询。在这里，我们正在搜索字符串“language”-

mysql> select * from DemoTable1554 where match(Title) against('language' in boolean mode);

这将产生以下输出-

+------------------------------------------+
| Title                                    |
+------------------------------------------+
| Adam Smith is working on Java language   |
| John smith is working on Python Language |
+------------------------------------------+
2 rows in set (0.00 sec)
