help formualting a query

I am having a hard time figuring out to do this, the SQL way. Doing in a
procedural way with a foreach would be deasy, but I suspect that a
properly formulated SQL query can achieve this.

I have a table that contains a  series of rows. Each row has a project key,
a start date, and an end date. There are multiple rows with different start
and end dates for each project.

I need to return something that contains, one row per project key, with the
min(star date) and max(end date) for ALL the records for that given
project.

Any suggestions?
