  1. Hi, I want to make a select from mysql to show some data in page. To show a table with data from mysql but limited to only 5 and this to show total number of rows. I'm thinking to make two selects. SELECT count(*) FROM table1 and after that to use mysql_num_rows to count total number in that table. Then another SELECT name,prename FROM table1 LIMIT 1, 5 to show only first 5 rows. It's there a way to use only one select insted of two but having the same results ? Thanks
