title: How to use alter table drop columns for columns present in a list?
body: <p>I have a list of all column names to be dropped from multiple tables in a schema, but not all the column names in the list have it's presence in all the tables.</p>
  <p>For the schema and the table name I have can I in a single query do a check if the columns match the column names in the list just drop that</p>
  <p>Say the column list to drop is</p>
  <pre><code>Drop_col = ['AB',' BC', FG', 'TR']
  </code></pre>
  <p>But my TABLE1 has only  'BC', 'TR' in the column list</p>
  <pre><code>Query =  ALTER TABLE SCHEMA_NAME.TABLE1 DROP COLUMN IN ({Drop}).format (Drop = Drop_col)
  </code></pre>
  <p>Something Like this?? or any other suggestions ??</p>
