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)
