mysql number of records in cursor without iterating?

Question

I am trying to write mysql procedure for below logic,

select id, fullname from users where fullname like concat(lastname, \' \', firstname, \' (\' , middlena         


        

Answer 1

Do a count before the cursor:

select count(*)
into @user_cnt
from users
where fullname like concat (
    lastname,
    ' ',
    firstname,
    ' (',
    middlename,
    '%'
    );

EDIT: If you want to do it after OPENING the cursor, try doing:

OPEN your_cursor;
select FOUND_ROWS() into user_cnt ;

Answer 2

Include SQL_CALC_FOUND_ROWS in your cursor select.Then on fetch use FOUND_ROWS(). It gives the number of records
