copied!<p>That's because you have no records in <code>BILLS</code> for <code>BILLDATE = '2013-09-02'</code> (I suppose that <code>WHERE BILLDATE >='08/01/2013' AND BILLDATE<='09/09/2013'</code> is a typo and you wanted to write <code>WHERE BILLDATE >='01/09/2013' AND BILLDATE<='03/09/2013'</code></p> <p>There're many DB specific methods to make your query, but I think if you have to do this types of query often, the best way to go is to create static <code>DATES</code> table, populate it with dates (from, for example <code>1900-01-01</code> till <code>3000-01-01</code>):</p> <pre><code>Date 1900-01-01 1900-01-02 1900-01-03 ... 2010-01-01 ... </code></pre> <p>and use it like:</p> <pre><code>select d.DATE, count(b.BILLDATE) as cnt from DATES as d left outer join BILLS as b on b.BILLDATE = d.DATE where d.DATE >='2013-09-01' and d.DATE <= '2013-09-03' group by d.DATE </code></pre> <p>Note also <a href="http://en.wikipedia.org/wiki/ISO_8601" rel="nofollow">ISO 8601</a> format for dates.</p> <p>If you don't care much about performance, you can use <a href="http://technet.microsoft.com/en-us/library/ms186243%28v=sql.105%29.aspx" rel="nofollow">recursive common table expression</a>:</p> <pre><code>with cte([Date]) as ( select convert(date, '20130901', 112) -- Start date union all select dateadd(dd, 1, [Date]) from cte where [Date] < '20130903' -- End date ) select c.[Date], count(b.BILLDATE) as cnt from cte as c left outer join BILLS as b on b.BILLDATE = d.DATE </code></pre>
