如何使用SUBSTRING_INDEX在MySQL中拆分字符串？
让我们首先创建一个表-
mysql> create table DemoTable1465 -> ( -> Name varchar(40) -> );
使用插入命令在表中插入一些记录-
mysql> insert into DemoTable1465 values('Chris Brown');
mysql> insert into DemoTable1465 values('David Miller');
mysql> insert into DemoTable1465 values('John Doe');使用select语句显示表中的所有记录-
mysql> select * from DemoTable1465;
这将产生以下输出-
+--------------+ | Name | +--------------+ | Chris Brown | | David Miller | | John Doe | +--------------+ 3 rows in set (0.00 sec)
以下是使用SUBSTRING_INDEX()在MySQL中拆分字符串的查询。在这里，我们拆分名字和姓氏字符串-
mysql> select -> substring_index(substring_index(Name, ' ', 1), ' ', -1) as StudentFirstName, -> substring_index(substring_index(Name, ' ', 3), ' ', -1) AS StudentLastName -> from DemoTable1465;
这将产生以下输出-
+------------------+-----------------+ | StudentFirstName | StudentLastName | +------------------+-----------------+ | Chris | Brown | | David | Miller | | John | Doe | +------------------+-----------------+ 3 rows in set (0.00 sec)
