Join them; it only takes a minute: mysql error Sign up how to display MySql error in php up vote 14 down vote favorite In PHP, I am trying to execute a long MySql query that depends on the user input. However, my query fails with the following message, "Query Failed". Actually I have printed this message whenever the query fails but I am having hard time looking for the reason php sql insert behind this failure. Unfortunately, I couldn't find it because the error is not specified on the web page. My question is, is there any way to display the error message that caused the failure on the web page. Thank you. Here's my code, $from= "Findings"; $where=""; if($service!= null) { $from = $from . ", ServiceType_Lookup"; $where= "Findings.ServiceType_ID= ServiceType_Lookup.ServiceType_ID AND ServiceType_Name= ". $service; if($keyword!= null) $where= $where . " AND "; } if( $keyword != null) { $where= $where . "Finding_ID LIKE '%$keyword%' OR ServiceType_ID LIKE '%$keyword%' OR Title LIKE '%$keyword%' OR RootCause_ID LIKE '%$keyword%' OR RiskRating_ID LIKE '%$keyword%' OR Impact_ID LIKE '%$keyword%' OR Efforts_ID LIKE '%$keyword%' OR Likelihood_ID LIKE '%$keyword%' OR Finding LIKE '%$keyword%' OR Implication LIKE '%$keyword%' OR Recommendation LIKE '%$keyword%' OR Report_ID LIKE '%$keyword%'"; } $query = "SELECT Finding_ID, ServiceType_ID, Title, RootCause_ID, RiskRating_ID, Impact_ID, Efforts_ID, Likelihood_ID, Finding, Implication, Recommendation, Report_ID FROM ".$from . " WHERE " . $where; echo "wala 2eshiq"; $this->result = $this->db_link->query($query); if (!$this->result) { printf("Query failed: %s\n", mysqli_connect_error()); exit; } $r = mysqli_query($this->db_link, $query); if($r==false) printf("error: %s\n", mysqli_errno($this->db_link)); php mysql share|improve this question asked Sep 1 '12 at 12:16 Tra

I just noticed that some inserts/records were NOT, or never created in the database. I would like to write a retry routine that if the insert fails to retry 3 times and then error out to the user. Just so you can see my code for the DB and the insert so you can see that I am NOT nuts... mysql_connect($hostname,$username, $password) or die(mysql_error()); mysql_select_db($dbname) or die(mysql_error()); Here is my insert code: $query = "INSERT INTO contacts VALUES ('','$name','$address','$city','$state','$zip','$phone','$email_address','$arrive','$depart','$room','$found','$promocode','$message','$datetimestamp','$ip')"; mysql_query($query); mysql_close(); I started out with an IF statement then into a loop but got lost. @Jay: So something like this: $conn = new mysqli($hostname, $username, $password, $dbname); // check connection if (mysqli_connect_errno()) { exit('Connect failed: '. mysqli_connect_error()); } $query = "INSERT INTO contacts VALUES ('','$name','$address','$city','$state','$zip','$phone','$email_address','$arrive','$depart','$room','$found','$promocode','$message','$datetimestamp','$ip')"; // Performs the $query on the server to insert the values if ($conn->query($qu
