Re: [PHP-DB] SELECT syntax
Or something like this?
SELECT * FROM `Bible_trivia` WHERE answer=`answer`;
Then match the results to trivia_answer_1 in php to see if correct.
if($trivia_answer_1 == $results) {
... do this
}
or a switch
switch ($results) {
case $trivia_answer_1:
... do this
case $trivia_answer_2
... do this

RE: [PHP-DB] SELECT syntax
Not terribly elegant, but this should work: SELECT `trivia_answer_1` AS `trivia_answer` FROM `Bible_trivia` WHERE `answer`=1 UNION SELECT `trivia_answer_2` AS `trivia_answer` FROM `Bible_trivia` WHERE `answer`=2 UNION SELECT `trivia_answer_3` AS `trivia_answer` FROM `Bible_trivia` WHERE `answer`=3 UNION SELECT `trivia_answer_4` AS `trivia_answer` FROM `Bible_trivia` WHERE `answer`=4; I have to say that it's likely that your design may not be the most optimal. What happens if you want 5 answers? Or 6?

Re: [PHP-DB] SELECT syntax
Hi In Oracle (and maybe others) you can use select case when answer=1 then trivia_answer_1 when answer=2 then trivia_answer_2 when answer=3 then trivia_answer_3 when answer=4 then trivia_answer_4 else null end answer from bible_trivia_table OR You can select all of them and process in PHP, should not be too hard to come up with a couple of lines of code to display only 1 variable based on the value of variable 5. Overhead should be pretty minimal as well You'll be writing something to display a value anyway Jack van Zanen - This e-mail and any attachments may contain confidential material for the sole use of the intended recipient.
