要搜索以逗号分隔的列表，请使用MySQL find_in_set()。这里不需要为此使用正则表达式。语法如下-select*fromyourTableNamewherefind_in_set(anyValue,yourColumnName);
让我们创建一个表-mysql>createtabledemo17
−>(
−>idintnotnullauto_incrementprimarykey,
−>first_namevarchar(50),
−>valuetext
−>);
借助insert命令将一些记录插入表中-mysql>insertintodemo17(first_name,value)values('John','50');
mysql>insertintodemo17(first_name,value)values('David','');
mysql>insertintodemo17(first_name,value)values('Adam','50,89');
mysql>insertintodemo17(first_name,value)values('Adam','49,89,43');
使用select语句显示表中的记录-mysql>select*fromdemo17;
这将产生以下输出-+----+------------+----------+
|id|first_name|value|
+----+------------+----------+
|1|John|50|
|2|David||
|3|Adam|50,89|
|4|Adam|49,89,43|
+----+------------+----------+
4rowsinset(0.00sec)
以下是查找字符串和下一个字符的查询-mysql>select*fromdemo17wherefind_in_set(50,value);
这将产生以下输出-+----+------------+-------+
|id|first_name|value|
+----+------------+-------+
|1|John|50|
|3|Adam|50,89|
+----+------------+-------+
2rowsinset(0.00sec)
