php - 在mysql选择查询中忽略#,\,/,大写,$

Question

我在下拉列表中填充所有用户名。我想忽略包含任何这些#, \, /, uppercase,的用户名$。我正在执行此查询，但它仍然显示带有 的记录\，例如 ad\name。

select account_name from dba_account where CAST(account_name  AS BINARY) RLIKE '[a-z]' 
and account_name not like '%#%' and account_name not like '%$%' and account_name not like 
'%/%' limit 50;

有什么建议么？？？？

谢谢你...

您的查询

select account_name from dba_account where CAST(account_name  AS BINARY) RLIKE '[a-z]' and account_name not like '%#%' and account_name not like '%$%' and account_name not like '%/%' limit 50;

不包含排除反斜杠的逻辑。
