如何在 MySQL 中搜索逗号分隔值表?
若要搜索逗号分隔值表,请使用 LIKE 运算符。我们首先创建一个表 -
mysql> create table DemoTable675(Value text); Query OK, 0 rows affected (0.55 sec)
使用 insert 命令向表中插入一些记录 -
mysql> insert into DemoTable675 values('10,56,49484,93993,211,4594'); Query OK, 1 row affected (0.28 sec) mysql> insert into DemoTable675 values('4,7,1,10,90,23'); Query OK, 1 row affected (0.41 sec) mysql> insert into DemoTable675 values('90,854,56,89,10'); Query OK, 1 row affected (0.21 sec) mysql> insert into DemoTable675 values('11,22,344,67,89'); Query OK, 1 row affected (0.10 sec)
使用 select 语句显示表中的所有记录 -
mysql> select *from DemoTable675;
这将产生以下输出 -
+----------------------------+ | Value | +----------------------------+ | 10,56,49484,93993,211,4594 | | 4,7,1,10,90,23 | | 90,854,56,89,10 | | 11,22,344,67,89 | +----------------------------+ 4 rows in set (0.00 sec)
以下是搜索逗号分隔值表的查询 -
mysql> select *from DemoTable675 WHERE Value LIKE '10,%' OR Value LIKE '%,10' OR Value LIKE '%,10,%' OR Value= '10';
这将产生以下输出 -
+----------------------------+ | Value | +----------------------------+ | 10,56,49484,93993,211,4594 | | 4,7,1,10,90,23 | | 90,854,56,89,10 | +----------------------------+ 3 rows in set (0.00 sec)
