title: if-statement with Parameter Query
body: <p>Please provide me with the SQL to copy and paste in order to have my if-statement prompt the user to input the <code>want_date</code>, but if the user just clicks "OK", then the default value will be the current date.</p>
  
  <pre><code>INSERT INTO tbl_New_part_ID_input ( want_date )
  SELECT [please input want date or just click ok to use todays current date] AS Expr1;
  </code></pre>
  
  <p>Thank you very much.</p>
