我们可以通过单个MySQL查询获得记录“ Jone Deo”或“ Deo Jone”吗？
为此，您可以使用LIKE子句。让我们首先创建一个表-
mysql> create table DemoTable -> ( -> ClientName varchar(100) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable values('John Smith');
mysql> insert into DemoTable values('Smith John');
mysql> insert into DemoTable values('Jone Deo');
mysql> insert into DemoTable values('Deo Jone');
mysql> insert into DemoTable values('Chris Brown');使用select语句显示表中的所有记录-
mysql> select *from DemoTable;
输出结果
这将产生以下输出-
+-------------+ | ClientName | +-------------+ | John Smith | | Smith John | | Jone Deo | | Deo Jone | | Chris Brown | +-------------+ 5 rows in set (0.00 sec)
以下是在单个MySQL查询中获取记录“JoneDeo”或“DeoJone”的查询-
mysql> select *from DemoTable
-> where ClientName
-> LIKE
-> (SELECT SUBSTRING_INDEX("%Jone% %Deo%", " ", -1))
-> or
-> (SELECT SUBSTRING_INDEX("%Deo% %Jone%", " ", 1));输出结果
这将产生以下输出-
+------------+ | ClientName | +------------+ | Jone Deo | | Deo Jone | +------------+ 2 rows in set (0.00 sec)
