Pdo Error Information

If you want just the error message you can just do this: $arr = $stmt->errorInfo(); echo($arr[2]); Result: You have an error in your SQL syntax; check the manual that corresponds to Advice: this is just a demonstration. If for some reason you don't like this behavior and prefer the old style with strings and NULLs only, then you can use the following configuration option to override it:

try{ connection=$this->get_connection();//here i brought my connection string connection->setAttribute(PDO::ATTR_EMULATE_PREPARES,false); connection->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION); /** Do your works here.. //$statement=$connection->prepare($sql); //if you are using errorInfo use after prepare statement before execute.here in this method i am fetchAll() That's most interesting function, with most astonishing features. Just use for debugging purpose. More modes are coming soon. http://php.net/manual/en/pdo.errorinfo.php

Are there any historically significant examples? Should I boost his character level to match the rest of the group? A module (like a database layer) should not report its errors. When you enable that attribute, the prepare() is virtually a no-op.

Most of time it is used not to count anything, but as a mere flag - just to see if there was any data returned. Excellent piece if work :) Reply ↓ Leave a Reply Cancel reply Please use [code] and [/code] around any source code you wish to share. So my code does... $stmt = $dbh->prepare("Some SQL"); if (($stmt !== false) && $stmt->execute(...)) { $rows = $stmt->fetch(...); if ($rows !== false) { while ... So, let's begin: Connecting.

It doesn't matter which query you are running.

Unfortunately I've found one place where a null is returned when it should be false. :-( Reply ↓ sak on November 16, 2011 at 17:36 said: using exceptions for errors is Prepared statements and LIKE clause Despite PDO's overall ease of use, there are some gotchas anyway, and I am going to explain some. To give you an example, consider the query below (the correct tablename is country, so this SQL will fail): $db = new PDO('mysql:host=localhost;dbname=sakila', 'user', 'pass'); $sql = 'select * from countrt'; query becomes LIMIT '10', '10' which is invalid syntax that causes query to fail.

Finally, to get the query executed, you must run execute() method of this object, passing variables in it, in the form of array.

(Or do they?) Does the code terminate?

Add it to the answer please, so I can accept it. They are as follows:
#define SQLITE_OK 0 /* Successful result */
#define SQLITE_ERROR 1 /* SQL error or missing database */

Once I've finished developing and debugging an application database errors normally only happen in exceptional circumstances such as not being able to connect to the db. Following the mission of this site, this article will disprove various delusions and bad practices, while showing the right way instead. PDO is most likely configured to not throw exceptions. In this case, catch the exception, gather the required information, and re-throw another Exception.

Don't enable to show error messages to the public in a release version. PDO query fails but I can't see any errors. However, there is no such thing as "the displaying of a back trace"! see simplified example: $field1 = 'foo'; $field2 = 'bar'; $insert_QUERY = $db->prepare("INSERT INTO table bogus(field1, field2) VALUES (:field1, :field2)"); $insert_QUERY->bindParam(':field1', $field1); $insert_QUERY->bindParam(':field2', $field2); $insert_QUERY->execute(); $databaseErrors = $insert_QUERY->errorInfo(); if( !empty($databaseErrors) ){ $errorInfo

The connection has to be made only once! Words that are both anagrams and synonyms of each other sort command : -g versus -n flag I have a new guy joining the group. This feature would have been more useful if it was possible to execute a statement prepared in another PHP instance. The return status code for the more traditional non OO APIs and exceptions for the rest.

Although this feature is magnificent by itself, it doesn't make a big deal for the particular application, where only one database backend is used anyway. Of course, it all comes down to the definition of an 'exceptional circumstance'... The only way I have learned to fix it is to just copy and paste the SQL into phpmyadmin and look for the output. thanks –adeel iqbal Jan 27 '14 at 9:52 add a comment| up vote 13 down vote I'm using this without any additional settings: if (!$st->execute()) { print_r($st->errorInfo()); } share|improve this answer

The only two exceptions are phptherightway.com and hashphp.org, but they miss a lot of important information. Interviewee offered code samples from current employer -- should I accept? it shows detailed error message with error code.now i don't seem this answer is anything :/ why not delete it .. –aimme Aug 18 '15 at 20:26 Ah, you've Thus, a sole PDO instance has to be created and then used through whole script execution.

In fact, the list is overwhelmingly short: only string and numeric literals can be bound. Very handy when we are selecting only one field: //Gettingthenamebasedonid

Another frequently asked question is caused by the fact that mysql won't update the row, if new value is the same as old one. Please note that positional placeholders let you write shorter code, but are sensitive to the order of arguments (which have to be exactly the same as the order of the corresponding
