If you want to insert all the columns then   insert into def select   from abc    here the number of columns in def should be equal to abc   if you want to insert the subsets of columns then   insert into def  col1 col2  col3   select scol1 scol2 scol3 from abc     if you want to insert some hardcorded values then   insert into def  col1  col2 col3  select  hardcoded value  scol2  scol3 from abc

With MySQL if you are inserting into a table that has a auto increment primary key and you want to use a built-in MySQL function such as NOW   then you can do something like this   INSERT INTO course payment  SELECT NULL  order id  payment gateway  total amt  charge amt  refund amt  NOW   FROM orders ORDER BY order id DESC LIMIT 10

If you you want to copy a sub-set of the source table you can do   INSERT INTO def  field 1  field 2  field3   SELECT other field 1  other field 2  other field 3 from  abc    or to copy ALL fields from the source table to destination table you can do more simply   INSERT INTO def  SELECT   from  abc
