    <p>I am getting 2 timestamps from the Oracle database start and end dates. They come in this format<code>yyyy-MM-dd HH:mm:ss.SSS</code></p> <p>Now I am getting another timestamp for comparison from a text file. It's in String format. Below is the code that I have written to extract the required info.</p> <pre><code> DateFormat f = new SimpleDateFormat("EEE MMM dd HH:mm:ss zz yyyy"); Date date = f.parse("Tue Aug 23 20:00:03 PDT 2011"); System.out.println("---date----" + f.format(date)); String originalDate = f.format(date); System.out.println("---originalDate----" + originalDate); DateFormat f2 = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS"); String dateParse = f2.format(date); System.out.println("---dateParse----"+dateParse); </code></pre> <p>The output that I am getting is a little strange and is very inconsistent. Below is sample ---date----Tue Aug 23 20:00:03 PDT 2011 ---originalDate----Tue Aug 23 20:00:03 PDT 2011 ---dateParse----2011-08-24 08:30:03.000</p> <p>In the above output I am interested in the ----dateparse--- value as I need this for comparison. Now if you see the values are varying in the ideal case both should be same value.</p> <p>The issue here is if the output varies with the timezone then how am I supposed to do comparison in the code from the data that is fetched from the database? </p> <p>I just need to see if --dateparse-- lies between the date ranges that I get from db. Will this code work properly independent of the timezone or there is some issue here. If the date is varying then my comparison can go wrong or is it the correct way with the above 2 outputs.</p> <p>Can you please let me know how I can resolve this issue.</p>

    1. COWhat is the time zone of the data in the database? (And is it *really* in a text field? You shouldn't need to parse the data coming out of the database...)

    2. COI agree with @Jon. You shoudn't have to parse a date from the Database as String. It should come as java.util.Date...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
