Just a heads up, integer zip codes might not always be valid!

Wait, can you really optimize without changing the column?

Not sure about that, I’d go with option B instead.

I feel like using a view might be a good option, but I wonder if it would still be slow since the underlying data type remains char.

I practiced a similar question where creating a view was suggested, but I'm uncertain if typecasting to integer would really improve performance here.

I think altering the table to organize on zip_code could help, but I can't recall if that requires changing the column type.

I remember something about optimizing queries, but I'm not sure if creating a copy of the table is the best approach.

I'm feeling pretty confident about this one. The Auto Deployment feature could potentially make the indexes unreachable, so I'm going to go with C.

I'm a bit unsure about this one. Is it the 15-digit contact ID or the 18-digit contact ID? I'll need to double-check the details on that.

Hmm, I'm a bit unsure about this one. I know SOAP messages have an envelope, but I can't quite remember if the header and body are required or just common parts. I'll have to think this through carefully.
