How to Get Error Details From MySQL Stored Procedure - php

Question

I am calling a mysql stored procedure using PDO in PHP
try {
$conn = new PDO("mysql:host=$host_db; dbname=$name_db", $user_db, $pass_db);
$stmt = $conn->prepare('CALL sp_user(?,?,#user_id,#product_id)');
$stmt->execute(array("user2", "product2"));
$stmt->setFetchMode(PDO::FETCH_COLUMN, 0);
$errors = $stmt->errorInfo();
if($errors){
echo $errors[2];
}else{
/*Do rest*/
}
}catch(PDOException $e) {
echo "Error : ".$e->getMessage();
}
that return below error because the name of the field in insert query was given wrong
Unknown column 'name1' in 'field list'
So i want to know if this is possible to get detailed error information something like:-
Unknown column 'Tablename.name1' in the 'field list';
that could tell me what column of which table is Unknown.

while creating the pdo connection, pass options like error mode and encoding:
The PDO system consists of 3 classes: PDO, PDOStatement & PDOException. The PDOException class is what you need for error handling.
Here is an example:
try
{
// use the appropriate values …
$pdo = new PDO($dsn, $login, $password);
// any occurring errors wil be thrown as PDOException
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$ps = $pdo->prepare("SELECT `name` FROM `fruits` WHERE `type` = ?");
$ps->bindValue(1, $_GET['type']);
$ps->execute();
$ps->setFetchMode(PDO::FETCH_COLUMN, 0);
$text = "";
foreach ($ps as $row)
{
$text .= $row . "<br>";
}
// a function or method would use a return instead
echo $text;
} catch (Exception $e) {
// apologise
echo '<p class="error">Oops, we have encountered a problem, but we will deal with it. Promised.</p>';
// notify admin
send_error_mail($e->getMessage());
}
// any code that follows here will be executed

I found this to be helpful for me. "error_log" prints to the php error log but you can replace with whatever way you'd like to display the error.
} catch (PDOException $ex){
error_log("MYSQL_ERROR"); //This reminds me what kind of error this actually is
error_log($ex->getTraceAsString()); // will show the php file line (and parameter
// values) so you can figure out which
// query/values caused it
error_log($ex->getMessage()); // will show the actual MYSQL query error
// e.g. constraint issue
}
p.s. I know this is a bit late but maybe it can help someone.
