Hi All :
I've Delphi application, I would like to copy Data from one mysql table to another mysql table with the same structure. for loop its seems too slow. is there any query to do that

insert into table2 select * from table1;
I suggest you still do it in batches. For example if you have a numeric primary key:
insert into table2 select * from table1 where primary_key_column between 1 and 5000;
Then just have Delphi call that statement, changing 1 and 5000 to the next batch, and so on.
I am trying to do that but there is an error occurred
when i write the "select a.code, a.qty from master a where a.sn between 2610 and 2630"
its return the correct result. but in the insert statement there is an error
