查询有什么问题？
What is wrong with the query?
我在 VB 中使用 asp.net 实现此查询，该查询的 objective 是整理 @yahoo.com 和 [= 以外的电子邮件数据14=]，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？
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%
