如何使用MySQL LIKE创建搜索系统并基于关键字显示结果？
要基于关键字显示结果，请按照以下语法使用LIKE运算符-
select *from yourTableName where yourColumnName LIKE '%yourValue%';
让我们首先创建一个表-
mysql> create table DemoTable812(Comments text);
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable812 values('Good Looking');
mysql> insert into DemoTable812 values('Awesome');
mysql> insert into DemoTable812 values('Looking Gorgeous');
mysql> insert into DemoTable812 values('Good Luck');
mysql> insert into DemoTable812 values('Have a nice day');使用select语句显示表中的所有记录-
mysql> select *from DemoTable812;
这将产生以下输出-
+------------------+ | Comments | +------------------+ | Good Looking | | Awesome | | Looking Gorgeous | | Good Luck | | Have a nice day | +------------------+ 5 rows in set (0.00 sec)
