Remi, if Cost1 is NULL you function will always return NULL.

IF @Cost2 < @ReturnValue OR @ReturnValue IS NULL

will fix it.

What do you mean "precise"?

There is no such thing in math. There is only number of precise figures.

Float has 53 precise figures, decimal precision depends on it's value. 25 as...

No, it does not.

But in composite index it's better to have strongest restriction first.

In your case index (address_id, address_type) will be used much more likely then (address_type, address_id).

Of course, it...

What you are trying to store in DECIMAL(38,6) what cannot be stored in FLOAT?

And better create index on this computed column. Clustered, if possible.

Clustered index is the best option for selecting range of data.

T2.Data,T2.ID,T1.Data

2,1,5

2,2,5

2,3,NULL

And on this...
