查询有什么问题？

Question

我正在使用VB 中的asp.net 实现此查询，该查询的目的是整理除@yahoo.com 和@gmail.com 之外的电子邮件数据，它显示错误：

“@yahoo”和“@gmail”附近的语法不正确。

"select * from print_venue where not (email_id like %" & "@yahoo.com" & "%) AND (email_id like %" & "@gmail.com" & "%)"

上面的查询有什么问题？

Answer 1

您忘记了 like 语句周围的引号

"select * from print_venue 
where not (email_id like '%" & "@yahoo.com" & "%') 
AND (email_id like '%" & "@gmail.com" & "%')"

必须是

email_id like '%@yahoo.com%'

而不是

email_id like %@yahoo.com%
