MySQL 查询从分隔符后返回子串?


使用 SUBSTRING() 返回分隔符后的值。我们首先创建一个表 -

mysql> create table DemoTable
-> (
-> Title text
-> );
Query OK, 0 rows affected (0.56 sec)

使用 insert 命令向表中插入一些记录 -

mysql> insert into DemoTable values('John is good in MySQL,Sam is good in MongoDB,Mike is good in Java');
Query OK, 1 row affected (0.19 sec)

使用 select 语句从表中显示所有记录 -

mysql> select *from DemoTable;

输出

这将产生以下输出 -

+-------------------------------------------------------------------+
| Title                                                             |
+-------------------------------------------------------------------+
| John is good in MySQL,Sam is good in MongoDB,Mike is good in Java |
+-------------------------------------------------------------------+
1 row in set (0.00 sec)

以下是返回分隔符后子串的查询。

mysql> select substring(Title, instr(Title, ',') + 1) as AfterDelimiter from DemoTable;

输出

这将产生以下输出 -

+---------------------------------------------+
| AfterDelimiter                              |
+---------------------------------------------+
| Sam is good in MongoDB,Mike is good in Java |
+---------------------------------------------+
1 row in set (0.03 sec)
