I see, Thanks

No. I remove store_result and use only fetch_result.
But it was mistake about interface changes, sorry.
I change all store_result calls (two times only in dbase.c) to
fetch_result with third parameter nrows=0.

As I found in fetch_result  code it counts number of rows returned by DB
and fetch only nrows. If nrows=0
it will return all rows fetched from DB

at line 368-369 (mysql/dbase.c):

if(nrows>0 && nrows<n)
                 n = nrows;
