请问大家mysql查寻如何可以通过正则来查询一个特定的数字啊?
例如我想查询字段中带有115数字的列,却想排除1115或者11555555这种,mysql支持这种查询吗?

对比着mysql手册写了一下, 写的很丑, 没办法, 没找到\D, (|[^0-9X])也给我报错, 唉. mysql5.5.24

<code>mysql> select '115' regexp '^115$|^115[^0-9X]|[^0-9X]115$|[^0-9X]115[^0-9X]' res
ult;
+--------+
| result |
+--------+
|      1 |
+--------+
1 row in set (0.00 sec)

mysql> select '1150' regexp '^115$|^115[^0-9X]|[^0-9X]115$|[^0-9X]115[^0-9X]' re
sult;
+--------+
| result |
+--------+
|      0 |
+--------+
1 row in set (0.00 sec)

mysql> select '11150' regexp '^115$|^115[^0-9X]|[^0-9X]115$|[^0-9X]115[^0-9X]' r
esult;
+--------+
| result |
+--------+
|      0 |
+--------+
1 row in set (0.00 sec)

mysql> select 'a115a' regexp '^115$|^115[^0-9X]|[^0-9X]115$|[^0-9X]115[^0-9X]' r
esult;
+--------+
| result |
+--------+
|      1 |
+--------+
1 row in set (0.00 sec)
</code>

不支持,效率太低,需要自己处理。

支持,不过效率不高。
SELECT mm,mm REGEXP '.星号[^1]115[^5].星号$' FROM test.a;
