如何在单个 MySQL 查询中获取多行?
mysqlmysqli database
要在单个 MySQL 查询中获取多行，请使用 LIKE 运算符。让我们首先创建一个表 −
mysql> create table DemoTable1385 -> ( -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> Name varchar(20) -> ); Query OK, 0 rows affected (0.90 sec)
使用 insert 命令在表中插入一些记录 −
mysql> insert into DemoTable1385(Name) values('Chris Brown');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable1385(Name) values('Adam Smith');
Query OK, 1 row affected (0.22 sec)
mysql> insert into DemoTable1385(Name) values('Carol Taylor');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable1385(Name) values('John Doe');
Query OK, 1 row affected (0.48 sec)
mysql> insert into DemoTable1385(Name) values('John Smith');
Query OK, 1 row affected (0.14 sec)
使用 select 语句显示表中的所有记录 −
mysql> select * from DemoTable1385;
这将产生以下输出 −
+----+--------------+ | Id | Name | +----+--------------+ | 1 | Chris Brown | | 2 | Adam Smith | | 3 | Carol Taylor | | 4 | John Doe | | 5 | John Smith | +----+--------------+ 5 rows in set (0.00 sec)
这是在单个 MySQL 查询中获取多行的查询 −
mysql> select * from DemoTable1385 where Name LIKE '%Smith';
这将产生以下输出 −
+----+------------+ | Id | Name | +----+------------+ | 2 | Adam Smith | | 5 | John Smith | +----+------------+ 2 rows in set (0.00 sec)
