我正在尝试连接到远程数据库。我确信远程数据库为我提供了所有的特权。但是当我尝试通过jdbc connection连接到远程mysql数据库时,我得到了这个错误。我的密码包含* and & symbol,我认为这是导致此error问题的原因。但我不知道如何escape those characters。请帮帮忙
java.sql.SQLException: Access denied for user 'myusername'@'myhost' (using password: YES)
"jdbc:mysql://myhost/mydb?use
我希望在不被jdbc驱动程序转换为本地时区的情况下将时间戳保存到数据库中。目前,只有MySQL和PostgreSQL对我来说很重要,但如果有独立于数据库的解决方案,我将不胜感激。
示例:
// i want that to be saved as 1970-01-01 00:00:00
TimeStamp ts = new java.sql.Timestamp(0);
// gets transformed to local time by jdbc driver (in my case to 1970-01-01 01:00:00)
st.setTimestamp(0, new java.
以下查询返回的行比在数据库中运行查询时多返回一行:
select distinct employeeId as facilityId,0 as numberOfRequests
from If_User
where role='Facility Staff'
and employeeId not in (select distinct facilityId
from IF_Request
where requestStatus='C'
