1.java.sql.date and Java.util.Date

Java.sql.Date is inherited from Java.util.Date and assumes that dates1 (java.sql.Date) is assigned to Dates2 (java.util.Date)

Dates2=new java.sql.Date (Dates1.gettime ()) can be performed by the following conversions;

2. The difference between the methods in Preparestament Settimestamp () and setdate () and getdate (), Gettimestamp () in resultset:

Gettimestamp (), Settimestamp () will get/set "date + Time" in the database, or it can be said to be a timestamp

GetDate (), setDate () ignores time, only gets/sets the "date" in which

To encounter a problem like this

When hibernate is applied, the Qurey object Qurey

Problem:

Query Query =ses.createquery (HQL);
Query. setDate ("EndTime", Newdate ());
At this time, the new Date () is truncated for seconds.

Workaround:

Java code
Query Query =ses.createquery (HQL);
Query. Settimestamp ("EndTime", Newdate ());

Summary: 1. If the datetime type is displayed in the database, use query. Settimestamp("EndTime", newdate can be solved ()); This problem can be set time to hour and seconds
