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.
