以下是带有动态数组的 MySQL LIKE 查询MySQL 限制范围无法显示前 3 行?
mysqlmysqli database
以下是仅显示范围内设置 LIMIT 的前 3 行的语法 −
select *from yourTableName limit yourStartIndex,yourEndIndex;
首先我们创建一个表 −
mysql> create table demo67 −> ( −> id int, −> user_name varchar(40), −> user_country_name varchar(20) −> ); Query OK, 0 rows affected (0.72 sec)
使用 insert 命令向表中插入一些记录 −
mysql> insert into demo67 values(10,'John','US'); Query OK, 1 row affected (0.19 sec) mysql> insert into demo67 values(1001,'David','AUS'); Query OK, 1 row affected (0.14 sec) mysql> insert into demo67 values(101,'Mike','UK'); Query OK, 1 row affected (0.09 sec) mysql> insert into demo67 values(102,'Carol','AUS'); Query OK, 1 row affected (0.11 sec) mysql> insert into demo67 values(110,'Chris','US'); Query OK, 1 row affected (0.36 sec) mysql> insert into demo67 values(105,'David','AUS'); Query OK, 1 row affected (0.08 sec)
使用 select 语句显示表中的记录 −
mysql> select *from demo67;
这将产生以下输出 −
+------+-----------+-------------------+ | id | user_name | user_country_name | +------+-----------+-------------------+ | 10 | John | US | | 1001 | David | AUS | | 101 | Mike | UK | | 102 | Carol | AUS | | 110 | Chris | US | | 105 | David | AUS | +------+-----------+-------------------+ 6 rows in set (0.00 sec)
这是 MySQL 限制显示前三行的查询 −
mysql> select *from demo67 limit 0,3;
这将产生以下输出 −
+------+-----------+-------------------+ | id | user_name | user_country_name | +------+-----------+-------------------+ | 10 | John | US | | 1001 | David | AUS | | 101 | Mike | UK | +------+-----------+-------------------+ 3 rows in set (0.00 sec)
