Question

下面的SQL查询适用于CASE WHEN中的所有检查，接受某些电子邮件。每当我运行查询检查电子邮件时，它有时会工作，有时它不会。我做了一个RTRIM（LTRIM（m.Email）），这也不起作用。在比较电子邮件时，我需要做些什么吗？

exec BuildingPros.uspGetEmployees 1697,'Email','someone@somewhere.net'


alter proc BuildingPros.uspGetEmployees

@Where  VARCHAR(12) = NULL,
@Equals VARCHAR(25) = NULL

Answer 1

我怀疑它适用于长度短于26个字符且电子邮件长度为26个字符或更长的电子邮件。 VARCHAR(25)不足以发送电子邮件地址。
