Inserting value from other table in query

[Michael T. Babcock]

I want to do:

SELECT @Rate:=Rate FROM Project WHERE ProjectID = 'x';
INSERT INTO BillingTime (Start, End, ProjectID, Rate) values (a, b, x, @Rate);

... but I'm sure its doable in a single query, even if I have multiple values to query, is it?

INSERT INTO BillingTime (Start, End, ProjectID, Rate) SELECT a, b, x, Rate FROM Project where ProjectID = x;

... but this doesn't work if I want to query values from multiple tables.
