Takahashi-san,

> EXEC SQL EXECUTE test_prep (2);

Could you please also verify for me if this works correctly if you use
a variable instead of the const? As in:

EXEC SQL BEGIN DECLARE SECTION;
int i=2;
EXEC SQL END DECLARE SECTION;
...
EXEC SQL EXECUTE test_prep (:i);

I guess the problem is that constants in this subtree are move to the
output literally instead treated as parameters.

Thanks.

Michael
