查询有什么问题？

Question

我在asp.net中使用VB实施此查询，该查询的目标是整理除@yahoo.com和@gmail.com以外的电子邮件数据，它显示错误：

＆＃39; @ yahoo＆＃39;附近的语法不正确和＆＃39; @ gmail＆＃34;。

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

上述查询有什么问题？

Answer 1

您忘记了like声明

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%
