Hi,

How can I select data from table into an existing table. I've redesigned
some tables and thus want my data to be copied from the old table to the new
one. Since the column order, names (and the number of columns) is not equal
i thought of using:

select column1,column2 into newtable from oldtable

THis however leads to an error that states that the table exists already.
Deleting the table is no option for me since I want the data to be in the
table with the new structure.

INSERT INTO newtable (SELECT column1, column2 FROM oldtable);

INSERT INTO newtable ( col1, col2 ) SELECT cola, colb FROM oldtable

Try insert into newtable select * from oldtable;

See insert syntax for more details..
