That is true. The last syntax has the limitation of being one row at a time, though. And I'm not sure it is supported on all RDBMSs. I think it was originally an Oracle extension to standard SQL that other vendors now support for compatibility. I'm looking at the draft SQL 2003 document, 5WD-02-Foundation-2003-09.pdf, section 14.8 and it looks like it's a non-standard syntax. Still, it's worth knowing about... and as I always say, use it if it makes sense to.

I'll also note that there are 2 ways to do an insert:

INSERT into apples (field1,field2....) select.....

and

INSERT into apples (field1,field2....) VALUES (....

are similar in syntax, and then there's

INSERT INTO Image set field1="foo",field2="bar",field3=12345;

Folks may feel more comfortable with the latter syntax, because they don't have to count which field they're on.

Interesting points. I've been sort of learning as I've gone along and looking at some code I wrote I've got a few blind inserts. I can see why it could easily become a problem when you change something in the database if it isn't specified in the code.

Thanks!
