You can do it this way:
<pre class="lang-sql prettyprint-override"><code>-- SAMPLE DATA
WITH
 tbl AS
 (
 Select 'A' &quot;A_TYPE&quot;, 1 &quot;SUBSCRIPTION_ID&quot;, To_Date('10.10.2022', 'dd.mm.yyyy') &quot;ACTIVE_DATE&quot;, Null &quot;INACTIVE_DATE&quot; From Dual Union All
 Select 'A' &quot;A_TYPE&quot;, 2 &quot;SUBSCRIPTION_ID&quot;, To_Date('11.10.2022', 'dd.mm.yyyy') &quot;ACTIVE_DATE&quot;, To_Date('14.10.2022', 'dd.mm.yyyy') &quot;INACTIVE_DATE&quot; From Dual Union All
 Select 'A' &quot;A_TYPE&quot;, 3 &quot;SUBSCRIPTION_ID&quot;, To_Date('12.10.2022', 'dd.mm.yyyy') &quot;ACTIVE_DATE&quot;, To_Date('14.10.2022', 'dd.mm.yyyy') &quot;INACTIVE_DATE&quot; From Dual Union All
 Select 'B' &quot;A_TYPE&quot;, 4 &quot;SUBSCRIPTION_ID&quot;, To_Date('13.10.2022', 'dd.mm.yyyy') &quot;ACTIVE_DATE&quot;, Null &quot;INACTIVE_DATE&quot; From Dual Union All
 Select 'B' &quot;A_TYPE&quot;, 5 &quot;SUBSCRIPTION_ID&quot;, To_Date('14.10.2022', 'dd.mm.yyyy') &quot;ACTIVE_DATE&quot;, To_Date('18.10.2022', 'dd.mm.yyyy') &quot;INACTIVE_DATE&quot; From Dual Union All
 Select 'B' &quot;A_TYPE&quot;, 6 &quot;SUBSCRIPTION_ID&quot;, To_Date('15.10.2022', 'dd.mm.yyyy') &quot;ACTIVE_DATE&quot;, Null &quot;INACTIVE_DATE&quot; From Dual 
 ),
</code></pre>
CTE To generate the dates for A_TYPE:
Here you can define range starting date (09.10.2022) and how many days you want the range to last (LEVEL &lt;= 11)
<pre class="lang-sql prettyprint-override"><code> dates AS
 (
 Select Distinct
 t.A_TYPE &quot;A_TYPE&quot;,
 d.RANGE_DATE &quot;RANGE_DATE&quot;
 From 
 (Select To_Date('09.10.2022', 'dd.mm.yyyy') + LEVEL - 1 &quot;RANGE_DATE&quot; From dual Connect By LEVEL &lt;= 11) d
 Left Join
 tbl t ON(1 = 1)
 Order By 
 t.A_TYPE,
 d.RANGE_DATE
 )
</code></pre>
And main SQL:
<pre class="lang-sql prettyprint-override"><code>SELECT
 d.A_TYPE &quot;A_TYPE&quot;,
 d.RANGE_DATE &quot;RANGE_DATE&quot;,
 (Select Count(*) From tbl Where A_TYPE = d.A_TYPE And ACTIVE_DATE &lt;= d.RANGE_DATE And Nvl(INACTIVE_DATE, To_Date('11.10.2062', 'dd.mm.yyyy')) &gt; d.RANGE_DATE) &quot;ACTIVE_COUNT&quot;
FROM
 dates d
</code></pre>
This is the result:
<pre class="lang-sql prettyprint-override"><code>/*

I have a table showing subscriptions with a column for active date and a column for inactive date. I need a query which counts the number of active subscriptions for each specific date in a date range.
I'm struggling to add in a row for each date in my date range so that I can then compare with the other date columns in my table.
Example of my table
<a href="https://i.stack.imgur.com/nRSFw.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/nRSFw.png" alt="enter image description here" /></a>
Example of the result I need
<a href="https://i.stack.imgur.com/5Vgg2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5Vgg2.png" alt="enter image description here" /></a>
