title: Is it possible to apply the dynamic data masking on already encrypted column in same table
body: <p>I was implemented the Always Encrypted and Dynamic data masking concepts in my azure SQL database on two different tables.</p>
  <p>But I have doubt like “Is it possible to apply the dynamic data masking on already encrypted column in same table”.</p>
  <p>I tried the above scenario it gives error like “The data type of column 'SSN' does not support data masking function 'partial'.”.</p>
  <p>I run the below query for applying the masking on already encrypted column.</p>
  <pre><code>ALTER TABLE [dbo].[CustomerTables]
  ALTER COLUMN [SSN] ADD MASKED WITH (FUNCTION = 'partial(0,&quot;XXX-XX-&quot;,4)');
  </code></pre>
  <p>Is it possible to apply the dynamic data masking on already encrypted column in same table?</p>
