I have a table like this:
create table1 (field1 int, field2 int default 5557, field3 int default 1337, field4 i
Just don't include the columns that you want to use the default value for in your insert statement. For instance:
INSERT INTO table1 (field1, field3) VALUES (5, 10);
...will take the default values for field2 and field4, and assign 5 to field1 and 10 to field3.
field2
field4
field1
field3
