I wish this help you I am looking for a solutions for my MySQL data copying related problem. I have a table TAB1 in a database DB1 that contains some data. Now I want some of these data rows to be migrated to another table TAB2 to some another database DB2.
code :
insert into db2.table2 (field1,field2,..,fieldN)
select field1,field2,..,fieldN from db1.table1
update 
db2.table2 as t2,
db1.table1 as t1
set 
t2.field1 = t1.field1,
t2.field2 = t1.field2,
t2.field3 = t1.field3
where t1.id = t2.id

fixed the issue. Will look into that further How to create table with existing table structure without iterate row by row like this in Oracle? in Advance. , If you are worried about iterating through the table:
code :
CREATE TABLE new_table
  AS (SELECT *
      FROM (select * old_table where rownum = 1) t
      WHERE 1=2
     );

wish of those help First of all you need to loop through all instances of selected rows and compare each row to the existing ones in results table.
I would do this in opposite process flow....collect an array of the values that already exist in results...then as you loop through the checked rows in main table compare that value to the array.
code :
$(function() {
  $(document).on("click", "#submit", function() {
    var $resBody = $('#results tbody'),
      // create array of rooms already in results
      existingRooms = $resBody.find('tr[data-room]').map(function() {
        return $(this).data('room')
      }).get();
    // log array for demo purposes
    console.log('existingRooms', JSON.stringify(existingRooms));
    
    // now loop through the selected checkboxes
    $("#schedule input:checked").each(function() {
      var $row = $(this).closest('tr'),
        room = $row.data('room');
      // is current room instance already in array?
      if ($.inArray(room, existingRooms) === -1) {
        $resBody.append($row.clone());
      } else {
        alert("Room " + room +' already selected');
      }
    });
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="schedule" class="table table-stripped table-bordered table-hover">
  <thead>
    <tr>
      <th></th>
      <th>time</th>
      <th>room</th>
      <th>presenter</th>
      <th>title</th>
      <th>detail</th>
    </tr>
  </thead>
  <tbody>
    <tr data-room="SE135">
      <td><input type="checkbox" value="yes"></td>
      <td>9:00am</td>
      <td class="room">SE135</td>
      <td>aaaaa</td>
      <td>aaaaaa</td>
      <td>aaaaaaaa</td>
    </tr>
    <tr data-room="SE145">
      <td><input type="checkbox" value="yes" checked></td>
      <td>9:00am</td>
      <td class="room">SE145</td>
      <td>aaaaab</td>
      <td>aaaaaa</td>
      <td>aaaaaaaa</td>
    </tr>
  </tbody>
</table>
<input id="submit" type="button" value="Submit">

<table id="results">
  <thead>
    <tr>
      <th></th>
      <th>time</th>
      <th>room</th>
      <th>presenter</th>
      <th>title</th>
      <th>detail</th>
    </tr>
  </thead>
  <tbody>

will help you I've come up with what appears to be a working solution:
Step 1: I use a SELECT INTO statement to back up the desired rows into a temporary table.
Select from a table and insert to another table and deleting it from the source table

seems to work fine Have a look at: MySQL Trigger - delete after update
What you want is to trigger a delete after your insert.
