This is kind of interesting ...
$query="SELECT * FROM quiettimequotation WHERE used = 0 ORDER BY RAND()
LIMIT 1";
works;
$query="SELECT * FROM bibleverses WHERE 'used' = 0 ORDER BY RAND() LIMIT 1";
doesn't! Having the ' around used makes that select command fail --- but
the UPDATE command requires it!
Thanks for those of you who responded to my question below. I am creating a
mailing list for my web site that I am wanting each entry which is randomly
selected from the database to only be used once and not be available again
until the entire list has been used. I needed the UPDATE command to change
the used column all back to 0 again once the last entry had been selected
from the database. I think I like programming mySQL stuff :) Ron
