Hi Suzanne,
When you say:
insert into table_2 select * from table_1
alls fine. All the records and fields will get
copied.
But when you say:
insert into table_2 select fieldname_1 from table_1
you are just selecting fieldname_1 from table_1
while
table_2 consists of fieldname_2 also.
So the correct sql statement will be:
insert into table_2(fieldname_1) select fieldname_1
from table_1;
The fieldname_2 will get its default value and if it
is an autoincrement field then the value will be
incremented and auotmatically inserted.
Hope this will clear your doubt.
