I was thinking along the same lines with both of your statements here.

I keep hearing this same old mantras: 

1.   Dynamic construction = SQL injection.

Cr*p! ( if you'll pardon my french)

Dynamic construction = SQL injection IF AND ONLY IF:

a.  You take text input from your user as part of the construction
b.  You do not sanitize the text.

There's no way that you are exposed to SQL injection if you base your
SQL statement on 
such the current content of OptionBoxes, ListLimited ComboBoxes,
selections in Listboxes 
etc,ect.

2. Dynaic SQL isn't optimised.

Big deal!

Design your indexes properly and what's the real performance difference
between:

"myProcedure Param1, Param2, Param3"
and
"Select ,,,,,, from myTable where .. Param1 and .... Param2 ,,,, and
Param3
order by ....."
