Something like
Expand|Select|Wrap|Line Numbers
  1. UPDATE table_xx, table_yy 
  2. SET table_xx.count=table_yy.number 
  3. WHERE table_xx.id=table_yy.id;
where you update the column `count` in `table_xx` with the values from column `number` in table `table_yy` as long as columns `id` in both tables match?

Assuming that you have created a table_y with an auto-increment key:
Expand|Select|Wrap|Line Numbers
  1. insert table_y (name) select name from table_x;
