krispykreme Posted January 17, 2008 Share Posted January 17, 2008 Not sure if these are related but I have a messaging system for my users which is done to the following... mysql_query("INSERT INTO message (src,dest,msg,time,inbox,crew,title,date) VALUES ('$id','$msgtoid','$msg','$time','inbox','$crw[0]','$title','$date');"); $event="You have recieved a message from <a href=profile.php?pid=$user>$pmp[0]</a>. The subject of the message is <a href=messages.php>$title</a>."; mysql_query("INSERT INTO newsfeed (userid,event,time) VALUES ('$id','$event','$time');"); sometimes the insert into message doesnt work it seems but the message title and such will show up in the news feed also my tables constantly have a *overhead* that appears like every 12 hours and stays like that till i *optimize* the table, right now a smaller table has a over head and is seen below... Space usage Type Usage Data 107,433 B Index 30,720 B Overhead 4,023 B Effective 134,130 B Total 138,153 B Optimize table is overhead bad? I cant find much documentation about it and would having a overhead make it have spotty inserts into tables? also if my database is very query intensive and information is constantly changing in some tables should i not use MyISAM? Thanks for your time as I'm very confused, the database is live and gets 300k+ page views and each page view has at least 2 query statements involved Link to comment https://forums.phpfreaks.com/topic/86398-solved-overhead-insert-not-always-inserting/ Share on other sites More sharing options...
fenway Posted January 17, 2008 Share Posted January 17, 2008 Overhead in the result of "holes" from deleting records. As for your inserts, they can't just fail and not report and error... unless you're not checking.

krispykreme Posted January 17, 2008 Author Share Posted January 17, 2008 thanks for the reply i personally dont know if there was an error since it has never happend to me but i guess i can turn on the error logs and that would keep track?

fenway Posted January 17, 2008 Share Posted January 17, 2008 You keep turn on logging, of course... but your script can also handle this.

krispykreme Posted January 18, 2008 Author Share Posted January 18, 2008 it happens to my users sometimes i guess for instance the message will show up in the news feed but not in the messages i search the messages table and it doesnt exist, but the newsfeed inserted it fine Link to comment https://forums.phpfreaks.com/topic/86398-solved-overhead-insert-not-always-inserting/#findComment-442912 Share on other sites More sharing options...
fenway Posted January 18, 2008 Share Posted January 18, 2008 How are messages / newfeeds related? Link to comment https://forums.phpfreaks.com/topic/86398-solved-overhead-insert-not-always-inserting/#findComment-442995 Share on other sites More sharing options...
krispykreme Posted January 18, 2008 Author Share Posted January 18, 2008 mysql_query("INSERT INTO message (src,dest,msg,time,inbox,crew,title,date) VALUES ('$id','$msgtoid','$msg','$time','inbox','$crw[0]','$title','$date');"); $event="You have recieved a message"; mysql_query("INSERT INTO newsfeed (userid,event,time) VALUES ('$id','$event','$time');"); they are both triggered one after another seeing how newsfeed insert is after the message insert so if a newsfeed insert was instructed, a message insert should of happend right before that, like i said before all the messages i send work and insert, but some people in the database seem to have issues Link to comment https://forums.phpfreaks.com/topic/86398-solved-overhead-insert-not-always-inserting/#findComment-443005 Share on other sites More sharing options...
fenway Posted January 18, 2008 Share Posted January 18, 2008 I would add a custom error handler, log all of the info, watch it for a while... this shouldn't happen without a proper DB warning.

krispykreme Posted January 19, 2008 Author Share Posted January 19, 2008 i think i found it while messing around whenever someone put a ' in the message it would stop it because i wasnt doing $title = mysql_real_escape_string($title); $msg = mysql_real_escape_string($msg); however i put that in there and i can now put the ' things and it goes through with that statement always something simple ; P Link to comment https://forums.phpfreaks.com/topic/86398-solved-overhead-insert-not-always-inserting/#findComment-443710 Share on other sites More sharing options...
