我想比较一下
query filter {
_._1.asOf === // how to compare it with date part only?
}
此处_._1.asOf的类型为Rep[java.sql.Timestamp]。我想要做的是仅将此时间戳的日期部分与java.sql.Date.valueOf(dateString)进行比较。

if (txtNodeName.Text==String.Empty)
{
MessageBox.Show("Please enter the Node Name in Textbox");
txtNodeName.Focus();
}
else
{
string n = txtNodeName.Text;
if (treeView1.SelectedNode == null)
{
treeView1.Nodes.Add(n, n);
}
else
{
treeView1.SelectedNode.Nodes.Add(n, n);
}
}
}

是java.util.Timestamp的子类型，因此您可以使用java.util.Date，getDate，getMonth，然后将其值与输出值进行比较getYear使用相同的getter。
主动提醒你，Jodatime库在jvm上处理DateTime时，你可以使用这个：https://github.com/tototoshi/slick-joda-mapper作为sql timestamp和jodatime的mapper。
