deciblelovechild Posted February 12, 2003 Share Posted February 12, 2003 hi i need some help with this, i\'ve done some research on this and the only thing i came up with is that dynamic sql is the only way to use a variable for table name. Is this true??? If so, how would you do that with the following code? $db = $_SESSION[\'User\']; $db = $db . \"_buddies\"; $online_query = \"select buddy_name from $db WHERE online= \'n\'\"; any help is truly appreciated. thanks in advance.... dlc Link to comment https://forums.phpfreaks.com/topic/146-i-need-to-use-a-variable-for-the-table-name-in-a-sql-query/ Share on other sites More sharing options...
metalblend Posted February 12, 2003 Share Posted February 12, 2003 That will work.. or you can do it the dirty way: [php:1:a9971eb821]$online_query = \"select buddy_name from \".$HTTP_SESSION_VARS[\'User\'].\"_buddies WHERE online= \'n\'\";[/php:1:a9971eb821] Hope that helps.

metalblend Posted February 13, 2003 Share Posted February 13, 2003 yes i\'m sure we all have used a variable in a query.. nothing fancy. see if there\'s an error in the query:[php:1:1527049cfd]$online_query = \"select buddy_name from \".$HTTP_SESSION_VARS[\'User\'].\"_buddies WHERE online= \'n\'\"; mysql_query($online_query) or die(\"Error : query failed.<br>MySQL said: <i>\".mysql_error().\"</i><br>rn\");[/php:1:1527049cfd] hope that helps.
