Is there any good way to display username? in jsp

all the data queried in the database are stored in userid,. I want to display username on the page

do you have to cycle through the list every time to add a column of usernames, or is there a better way?

can't you query with a table and find out a username?

MySQL Query : SELECT * FROM `codeshelper`.`v9_news` WHERE status=99 AND catid='6' ORDER BY rand() LIMIT 5
MySQL Error : Disk full (/tmp/#sql-temptable-64f5-1bdc3aa-3063c.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")
