MySQL模式名称中是否匹配3个或多个“ a”？
以下是语法-
select * from yourTableName where yourColumnName like '%a%a%a%';
让我们首先创建一个-
mysql> create table DemoTable1393 -> ( -> CountryName varchar(40) -> );
使用insert在表中插入一些记录-
mysql> insert into DemoTable1393 values('andorra');
mysql> insert into DemoTable1393 values('australia');
mysql> insert into DemoTable1393 values('argentina');
mysql> insert into DemoTable1393 values('austria');使用选择显示表中的所有记录-
mysql> select * from DemoTable1393;
这将产生以下输出-
+-------------+ | CountryName | +-------------+ | andorra | | australia | | argentina | | austria | +-------------+ 4 rows in set (0.00 sec)
以下是查询以匹配列中的3个或更多“a”的模式-
mysql> select * from DemoTable1393 where CountryName like '%a%a%a%';
这将产生以下输出-
+-------------+ | CountryName | +-------------+ | australia | +-------------+ 1 row in set (0.00 sec)
