Shame on me. :-( Yes, the docs need much more work.

Please check the test source under .../ecpg/test.
How about this
if (cond) strcpy(query, "select count (*) from tpm");else strcpy(query, "select count (*) from tpm where col1 =
?");
exec sql prepare MM from :query;exec sql declare prep cursor for MM;
exec sql open prep using :cislo1;
exec sql whenever not found break;while (1){ exec sql fetch in cur into :cislo2;}
But speaking of this. It appears ecpg cannot do prepares without variables
at the moment. This is a bug. I just didn't see this so far.
