MySQL 中包含“The”的文本字符串操作
可以使用 ORDER BY TRIM()。我们首先创建一个表 -
mysql> create table DemoTable -> ( -> Title text -> ); Query OK, 0 rows affected (1.09 sec)
使用插入命令在表中插入一些记录 -
mysql> insert into DemoTable values('MongoDB is a no SQL database'); Query OK, 1 row affected (0.18 sec) mysql> insert into DemoTable values('The MySQL is a relational database'); Query OK, 1 row affected (0.22 sec) mysql> insert into DemoTable values('The Java language is good'); Query OK, 1 row affected (0.35 sec) mysql> insert into DemoTable values('Python is good language'); Query OK, 1 row affected (0.17 sec)
使用 select 语句显示表中的所有记录 -
mysql> select *from DemoTable;
这将产生以下输出 -
+----------------------------------+ | Title | +----------------------------------+ | MongoDB is a no SQL database | |The MySQL is a relational database| | The Java language is good | | Python is good language | +----------------------------------+ 4 rows in set (0.00 sec)
以下是包含“The ”的文本字符串操作的查询 -
mysql> select *from DemoTable -> order by trim(leading 'The ' from Title);
这将产生以下输出 -
+----------------------------------+ | Title | +----------------------------------+ | The Java language is good | | MongoDB is a no SQL database | |The MySQL is a relational database| | Python is good language | +----------------------------------+ 4 rows in set (0.00 sec)
