我在mysql中有三条记录:
1。 a:7:{s:10:"state_name";s:11:"West Bengal";s:7:"city_id";a:40:{i:0;s:4:"1166";i:1;s:4:"1454";i:2;s:4:"1455";i:3;s:4:"1456";i:4;s:4:"1458";i:5;s:4:"1459";i:6;s:4:"1460";i:7;s:4:"1461";i:8;s:4:"1463";i:9;s:4:"1464";i:10;s:4:"1465";i:11;s:4:"1466";i:12;s:4:"1468";i:13;s:4:"1469";i:14;s:4:"1470";i:15;s:4:"1471";i:16;s:4:"1473";i:17;s:4:"1474";i:18;s:4:"1475";i:19;s:4:"1476";i:20;s:4:"1478";i:21;s:4:"1479";i:22;s:4:"1480";i:23;s:4:"1481";i:24;s:4:"1483";i:25;s:4:"1484";i:26;s:4:"1485";i:27;s:4:"1486";i:28;s:4:"1488";i:29;s:4:"1489";i:30;s:4:"1490";i:31;s:4:"1491";i:32;s:4:"1493";i:33;s:4:"1494";i:34;s:4:"1495";i:35;s:4:"1496";i:36;s:4:"1498";i:37;s:4:"1499";i:38;s:4:"1500";i:39;s:4:"1501";}s:6:"gender";s:4:"male";s:3:"age";s:0:"";s:12:"category_ids";s:2:"68";s:16:"product_type_ids";s:2:"30";s:18:"min_purchase_price";s:1:"0";}
2。 a:7:{s:10:"state_name";s:11:"West Bengal";s:7:"city_id";a:8:{i:0;s:4:"1465";i:1;s:4:"1466";i:2;s:4:"1467";i:3;s:4:"1471";i:4;s:4:"1475";i:5;s:4:"1476";i:6;s:4:"1478";i:7;s:4:"1479";}s:6:"gender";s:0:"";s:3:"age";s:4:"0-30";s:12:"category_ids";s:2:"58";s:16:"product_type_ids";s:0:"";s:18:"min_purchase_price";s:2:"50";}
3。 a:7:{s:10:"state_name";s:11:"West Bengal";s:7:"city_id";a:1:{i:0;s:4:"1475";}s:6:"gender";s:6:"female";s:3:"age";s:4:"0-30";s:12:"category_ids";s:2:"58";s:16:"product_type_ids";s:0:"";s:18:"min_purchase_price";s:3:"100";}
列名为conditions_serialized
。
现在我正在尝试编写一个sql查询来获取city_id
1475的所有记录。
我的代码就像:
SELECT `main_table`.*, `rule_coupons`.`code` FROM `salesrule` AS `main_table` LEFT JOIN `salesrule_coupon` AS `rule_coupons` ON main_table.rule_id = rule_coupons.rule_id AND rule_coupons.is_primary = 1 WHERE (conditions_serialized regexp 'city_id";a:[0-9]*:{.*(i:[0-9]*;s:[0-9]*:"1475";)}')
但是这只有2条记录显示第2和第3,而不是第一条。 你可以检查我的查询并纠正它为什么没有全部显示吗?
提前致谢。
答案 0 :(得分:0)
您正在明确寻找 1475
city_id";a:[0-9]*:{.*(i:[0-9]*;s:[0-9]*:"**1475**";)}
将其更改为此以从3条记录中获取记录。注意:从3到5位
city_id";a:[0-9]*:{.*(i:[0-9]*;s:[0-9]*:"\d{3,5}";)}
