1062 Duplicate Entry Error Fix

[Loon 0]

What does that mean, in Layman's terms, enigma? I mean, I changed my sesskey back to varchar(32), no autoincrement, but I'm still getting at the bottom of the page - primarily when I go to login or create_account and then go to another page:

 

1062 - Duplicate entry 'd588ac8f1fffe6b3c490188a40eaafce' for key 1

 

insert into sessions values ('d588ac8f1fffe6b3c490188a40eaafce?osCAdminID=f3cdab335d59c0920155ebdb035fe1c4', '1156214611', 'cart|O:12:\"shoppingcart\":4:{s:8:\"contents\";a:0:{}s:5:\"total\";i:0;s:6:\"weight\";i:0;s:12:\"content_type\";b:0;}language|s:7:\"english\";languages_id|s:1:\"1\";currency|s:3:\"USD\";navigation|O:17:\"navigationhistory\":2:{s:4:\"path\";a:1:{i:0;a:4:{s:4:\"page\";s:18:\"create_account.php\";s:4:\"mode\";s:3:\"SSL\";s:3:\"get\";a:1:{s:6:\"osCsid\";s:76:\"d588ac8f1fffe6b3c490188a40eaafce?osCAdminID=f3cdab335d59c0920155ebdb035fe1c4\";}s:4:\"post\";a:0:{}}}s:8:\"snapshot\";a:0:{}}wishList|O:8:\"wishlist\":0:{}')

Can you help me out in regards to what to do?

 

I just ran into this problem - Duplicate Entry in the sessions table - after downloading my client's /includes/languages/english.php and /includes/languages/english/*.php files. The cart owner edits these files in the osC backend admin tool as they're his information regarding everything - shipping, etc.

 

Start with the page where you are getting the error (mine was on catalog_index.php) and go BACK to the page where the link is to the problem page. My link was on index.php. Now, hover over the link and check the URL that it's going to send you to. Does it have multiple session IDs in the URL? Appended to each other behind the URL to the page?

 

I'll put some spaces in but an example:

www . site . com/ catalog_index.php ? osCsid=b4a0b7ae7bfed16e797ddf0a3c56a940 ? osCAdminID=bf6255d450ad1a1e409bfcd189b3aa9d

 

Notice the TWO session IDs appended to each other (one osCsid and one osCAdminID). And the area between quotes, in red, in your example. I've seen 4 or 5 appended to each other. The only place I have this problem is in the languages files that my cart owner has edited himself. He copies links from his browser, while he's logged into the cart on one browser and into the admin area on another browser. Then he pastes those copied links into a language page (Yup, osCAdminID=xxxxxx.... and all) and saves it. Now it's a permanent part of the file and will always display, AND will always add the current users osCsid in there too so of course it's too long! or a duplicate or whatever.

 

Take your production languages files and go through them. A good text editor will find the pasted in ids in no time. This doesn't help with the other problems in this thread but I think it may be the answer to your example above.

I am using the contrib "FAST EASY CHECKOUT 3.2" and "HOW DID YOU HEAR ABOUT US? 1.5"

 

When I hit "continue" on my create_account3.php page, I get this error:

 

1062 - Duplicate entry '11' for key 1

insert into customers_info (customers_info_id, customers_info_date_of_last_logon, customers_info_number_of_logons, customers_info_date_account_created, customers_info_date_account_last_modified) values ('11', now(), '1', now(), now() )

but it does successfully writes the customer's info to the db

 

any ideas why this is happening or how to fix it?

Hi guys,

 

 

I have a similar problem and it must definitely be casued by a contribution so maybe if we all knew what mods were installed on everybody's osc's that are having these problems?

 

Here's mine:

 

I have SPPC installed (as well as PDFexport, CVV mod, MaxiDVD multiple images, Who's Online Enhancement, AutoThumbnail, Easy Populate, SEO Assistant, SEO URLs, to name a few) , and they are working properly except for one thing, when i try to copy a product, it gives me a 1062 - Duplicate entry '0-638' for key 1. This has only started happening after SPPC was installed...

 

When you hit the back button, the new product has been copied correctly and appears in the list.

 

Now, when you browse the product listing on the main site, the price is displayed correctly, but when you click into a product info page, the price appears as 0.00. However, when you add the product to your cart anyway, the price in the shopping cart appears correctly.

 

So, its just the product info page which seems to get affected by this problem. Would anyone have any idea why this is happening? Should i change something to INT instead of autoincrement in the DB or is there another way?

 

Thanks.

Just for the record, it seems using Paypal_IPN_v2.2 and Unique Order Number contribs will also get you 1062 Duplicate entry error. Customers might choose to use Paypal and leave without completing the order leaving an Order_ID of "0" in Order DB. The next customer that comes along and choses Paypal as their payment method won't be able to complete the order and will get to see the previous customer's name, contacts and shipping information.

 

Can't find any remedies for this issue yet.

After trying to resolve a Duplicate Entry 1062 Error for several hours, I finally figured out the problem. My client had purchased an SSL certificate and accidently typed in the wrong domain name to purchase it under. There was only one letter difference, but the wrong ssl domain was being recorded in the sessions table and not allowing the creation of accounts. I have disabled ssl forr now until the correct certificate is purchased. I don't think this is the problem for most, but maybe it will help someone.

I also get a duplicate entry error - when copying products.

I have a lot of contribs & hacks ...

I know only a little of sessions & databases, rely on guesswork mostly. So Im guessing it has something to do with the product descriptions. Mostly because Ive done a bit of messing around with short descriptions & the like. .. Although Key 1 probably means "products_id" in which case, yeah It needs to have a different ID... i guess.

After installing, I received the following error message on every page in the admin section. My error was ...

 

1062 - Duplicate entry 'c07c86415d6c4ccdc061a352de1fe702' for key 1

 

insert into sessions values ('c07c86415d6c4ccdc061a352de1fe7022032cd70', '1186804470', 'language|s:7:\"english\";languages_id|s:1:\"1\";selected_box|s:13:\"configuration\";')

 

 

I noticed the "duplicate entry" was a truncated version (32 char) of the value in the "insert into sessions values" SQL (40 char). It seems the "sesskey" column in "sessions" should be varchar(40) and not varchar(32). Running the following SQL against my database fixed this problem for me. Make sure you are in the correct database (MySQL catalog) for your osCommerce setup before running.

 

ALTER TABLE `sessions` MODIFY COLUMN `sesskey` VARCHAR(40) NOT NULL;

 

 

In general, the session key should be a unique, but random, identifier, and the total space of random identifiers should be sparsely populated with actively used identifiers at any given time. Auto-incremented integers are a bad idea because they are unique, but not random, and all the active ones are next to each other. It is easy to guess neighboring active session identifiers and impersonate another user.

Hello, I was also receiving a similar error, which after some thorough research I had found that when the function _sess_write was looking up the $key value (which should only be 32 char long) the $key value actually had the 32 char long key plus ?active= blah blah so, somewhere something was setting the key to be a key + some http variables, at any rate, i just added 2 lines to my _sess_write function:

 

	function _sess_write($key, $val) {
  global $SESS_LIFE;

  $expiry = time() + $SESS_LIFE;
  $value = $val;

  //trim off extra crap on key
  $key = substr($key, 0, 32);

  $check_query = tep_db_query("select count(*) as total from " . TABLE_SESSIONS . " where sesskey = '" . tep_db_input($key) . "'");
  $check = tep_db_fetch_array($check_query);

  if ($check['total'] > 0) {
	return tep_db_query("update " . TABLE_SESSIONS . " set expiry = '" . tep_db_input($expiry) . "', value = '" . tep_db_input($value) . "' where sesskey = '" . tep_db_input($key) . "'");
  } else {
	return tep_db_query("insert into " . TABLE_SESSIONS . " values ('" . tep_db_input($key) . "', '" . tep_db_input($expiry) . "', '" . tep_db_input($value) . "')");
  }
}

 

For those of you who dont know where to find that particular function, it is in the includes/functions/sessions.php file.

 

Hope this helps...

I met this problem when I used SSL.

My solution is changing the PHP code from

tep_redirect(URL);

to

echo '<html><head><meta http-equiv="refresh" content="0;URL=' . URL . '"></head></html>';

exit();

in login.php, create_account.php, and checkout_process.php.

 

Try it. It may work.

Folks! This is the solution you are looking for. If you change sesskey to INT you will always get a "duplicate entry for key 1" statement.

Just keep sesskey as a VARCHAR and then increase the size above 32 (I made mine 64) and make sure you turn off auto-increment as well.

 

Simple!

//trim off extra crap on key

$key = substr($key, 0, 32);

Thank you.

 

Your fix solved my duplicate entry error.

 

Now to solve the cookie vs. session problem that causes this situtation.

Hm i got the same problem but either didn't solve the Problem

Hi all. I've researched this to the hilt, and I want to post a fix to the error I've been getting all along, which I've finally put an end to. It's the ol' 1062 Duplicate Entry error, and I have a fix for all. Everybody seems to get these, eventually, but very few people post about 'em in here.

 

The Problem -- Duplicate Entry 1062 Errors:

I kept having a duplicate error report for sessions. It is a problem with sessions. I was having this error everytime I selected create_account, or wishlist_help.

 

The Fix:

1) Go to your phpmyadmin, and select the sessions table

 

2) Select sesskey

 

3) Click edit

 

4) It's probably set at the OSC default, which is varchar(32). This is a mistake! Change the type to INT, the length/values should stay at 32.

 

5) Scroll all the way across to where you see extras and select AUTOINCREMENT from the drop down box.

 

6) Hit save button

 

All 1062 Duplicate Enty errors will not be resolved. You won't get 'em again!

 

 

If I am correct, OsCommerce creates sessions id for every visit to your website, in case a visitor has cookies disabled. Somehow during configuration, the sessions table probably wasn't configured to autoincrement. This was a simple fix that you wouldn't even need to change any of the values for your test runs. Just fix the sesskey and you're good to go!

Hi all. I experienced the same problem yesterday. The log is below:

Using my phpmyadmin 2.11.9 I looked for the "sessions" configuration and noticed that the index value for the utilized space was corrupted and red colored.

I used the phpmyadmin optimizer. The index was dimensioned to 4,096 B, black colored, and the problem was solved.

 

Hope this can help you.

Hi all,

 

I had the following on a client's site that was running a clean OsC2.2 which I then added the SPPC mod to:

 

1062 - Duplicate entry '0-133' for key 1

 

insert into products_groups (customers_group_id, customers_group_price, products_id) values ('', '', '133')

 

[TEP STOP]

 

This error occured when the client tried to use the duplicate product function. After reading this thread about 10 times over along with a lot of other forums posts elsewhere on 1062s, I saw the pattern between everyone's error and worked out why my client was getting his.

 

As I understand a 1062 happens because somewhere in your database a field is not auto-incrementing when it should be. The error tells you which database table to look in (in the case I quote above it was products_groups). Try setting the first field (in this case customers_group_id) to auto-increment. This will then prevent the duplicate entries. I hope that helps those of you that are having trouble.

 

Happy OsC'ing,

I get the same error with products_to_categories.... I tried your "auto-increment" change, and that "moved" the error to the customer_group DB!

 

The error happens when I try to add a new, or update an existing product!

Thx 4 this fix, works fine.

 

If you have problems and cant use your mysqladmin/phpmysqladmin or other mysql server software corectly,

 

dump the sessions table with this code:

 

DROP TABLE IF EXISTS sessions;

 

CREATE TABLE sessions (
 sesskey int(32) NOT NULL auto_increment,
 expiry int(11) unsigned NOT NULL,
 value text NOT NULL,
 PRIMARY KEY (sesskey)
);

 

If you are done, delete the osc Cokkies in your browser, reload the side and WOW ... ^^

 

Best regards Peter

 

"Edit: one ask i have about this error: on the 2.2RC2a i dont get this error with this sessions table:

 

CREATE TABLE `sessions` (
 `sesskey` varchar(32) NOT NULL default '',
 `expiry` int(11) unsigned NOT NULL default '0',
 `value` text NOT NULL,
