    <p>In my android application, I use STRFTIME function to get data from SQLite by comparing different Date Strings. </p> <p>I set Promotion <code>StartDate</code> and <code>EndDate</code> to <code>2013-10-07</code> and <code>2013-12-31</code> respectively. Promotion exists when current DateTime is between <code>StartDate</code> and <code>EndDate</code>.</p> <p>The following is a complete list of valid strftime() substitutions:</p> <pre><code>%d day of month: 00 %f fractional seconds: SS.SSS %H hour: 00-24 %j day of year: 001-366 %J Julian day number %m month: 01-12 %M minute: 00-59 %s seconds since 1970-01-01 %S seconds: 00-59 %w day of week 0-6 with Sunday==0 %W week of year: 00-53 %Y year: 0000-9999= </code></pre> <p>And I use the following query to retrieve the data.</p> <pre><code>Select * From Sal_Promotion p, Sal_Promotion_CustomerTypeAndProduct pd Where p.Sal_PromotionID = d.Sal_PromotionID and strftime('%s','now') &gt;= strftime('%s',Sal_StartDate) and strftime('%s','now') = strftime('%s',Sal_EndDate) and Sal_CustomerTypeID = customerTypeID and p.Sal_PromotionID = promoID; </code></pre> <p>When I tested my application on 07 Oct 2013 morning 7 am, I get the following output.</p> <p><em><strong>Output:</em></strong> </p> <p>StartDate: 2013-10-07 00:00:00 (Value: 1381104000)</p> <p>EndDate: 2013-12-31 00:00:00 (Value: 1388448000)</p> <p>CurrentDateTime: 2013-10-07 07:00:00 (Value: 1381100400)</p> <p>CurrentDateTime value should be between StartDate and EndDate. But why the value is wrong? Current DateTime is 3600 seconds (1 hour) later than StartDate.</p> <p>My current city is Singapore (GMT+8:00). Is it because of time zone difference?</p> <p>Can someone point me out what is the problem?</p>

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.
