MySQL Error “Query was empty”

Question

$send_event = $db->query(sprintf("SELECT `bmembMember` FROM `bmembBusiness` = '%u' WHERE `bmembBusiness` = '%u' ORDER BY `bmembId` DESC", $bs['busId'])) OR die('Cron not run') ;
while($se=$db->fetch_row($send_event))
{
$text = "The {$bs['busName']} business went bankrupt\, all members have been made redundent." OR die('Cron not run');

Thanks

Answer 1

Your sprintf uses 2 values, but you only provide one. One isn't needed anyway and that line should be

$send_event = $db->query(sprintf("SELECT `bmembMember` FROM `bmembBusiness` WHERE `bmembBusiness` = '%u' ORDER BY `bmembId` DESC", $bs['busId'])) OR die('Cron not run') ;

Answer 2

修复应该修复查询的FROM子句。

 ...FROM `bmembBusiness` WHERE...

Answer 3

Highted area of query is wrong,

"SELECT bmembMember FROM bmembBusiness = '%u' WHERE bmembBusiness = '%u' ORDER BY bmembId DESC", $bs['busId'])

Try This Which should Fix the query :-

SELECT bmembMember FROM Table_name WHERE bmembBusiness Like '%u' ORDER BY bmembId DESC, abs(busId);
