Hi, I know that select return a number of records, but i i use LIMIT i can't know how many row actualy is, because it's alway smaller than limit. Only solution I know for now is with 2 queryes. First query to get all the data, and than second with limit. But this is not something i want. -- bye, Uros mailto:uros@sir-mag.com Monday, May 13, 2002, 7:47:01 PM, you wrote: SL> On 5/12/02 3:22 PM, "Uros Gruber" <uros@sir-mag.com> wrote: >> Hi! >> >> Is it possible for example I have one db with 100.000 >> entries.
