Main topic: How to determine this date is a day, please help. Servers: R9lu (fish in late swimming) Credit value: 100 Forum: Java JSP / servlet / javabean problem points: 20 replies: 13 Posted: 2004-8-24 16:30:06 There are two small problems
1. What is the value of the date type (04-8-24 0: 0: 0: 0) from a result set, how to save him to a variable
2. How do you get the date of the day if you save your dates into a character.
The ultimate goal hopes to get this date is the day of the week. Even the novice, please help solve it.

The worst method in the world:
<% @ Page ContentType = "Text / HTML; Charset = GB2312" Language = "Java" Import = "java.sql. *" ErrorPage = ""%>
<% @ Page Import = "java.util. *"%>
No title document </ Title></p>
<p></ hEAD></p>
<p><body></p>
<p><%</p>
<p>Java.util.date Date = new java.util.date (104, 8, 24, 0, 0);</p>
<p>Out.println (Date.getDay ());</p>
<p>%></p>
<p></ body></p>

<p>For example, in SQL Server: SELECT datepart (weekday, '2004-8-23')</p>

<p>But the getday () method is only Date type data, and my date value is obtained from a result set, how to save this dates value into a variable and still DATE.</p>
<p>I am using String RundateStr = ParentBean.getstring ("Rundate");</p>
<p>Can only save it into a string type</p>
