Database Errors - Duplicate Entries - How Did You Hear About Us Mod

When I have "How did you hear about us" mod installed, I get this wierd error when I create a new account:

1062 Duplicate entry '765' for key 1
in:
[insert into customers_info (customers_info_id, customers_info_number_of_logons, customers_info_date_account_created, customers_info_source_id) values ('765', '0', now(), '1')]

I ran the SQL patch that came with the mod, I ran it via "phpMyAdmin" and it gave an error as soon as I did, it said:

**Error

SQL query:

ALTER TABLE customers_info ADD customers_info_source_id int NOT NULL AFTER customers_info_date_account_last_modified;

MySQL said: Documentation
#1060 - Duplicate column name 'customers_info_source_id' **

Here is the SQL patch that I applied:

DROP TABLE IF EXISTS sources;
CREATE TABLE sources (
  sources_id int NOT NULL auto_increment,
  sources_name varchar(64) NOT NULL,
  PRIMARY KEY (sources_id),
  KEY IDX_SOURCES_NAME (sources_name)
);

INSERT INTO sources VALUES (1, 'Google');
INSERT INTO sources VALUES (2, 'Yahoo!');
INSERT INTO sources VALUES (3, 'AOL');
INSERT INTO sources VALUES (4, 'MSN');
INSERT INTO sources VALUES (5, 'ZenCart');

DROP TABLE IF EXISTS sources_other;
CREATE TABLE sources_other (
  customers_id int NOT NULL default '0',
  sources_other_name varchar(64) NOT NULL,
  PRIMARY KEY (customers_id)
);

ALTER TABLE customers_info ADD customers_info_source_id int NOT NULL AFTER customers_info_date_account_last_modified;


INSERT INTO configuration (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, set_function, date_added) VALUES ('Display "Other" Referral option', 'DISPLAY_REFERRAL_OTHER', 'true', 'Display "Other - please specify" with text box in referral source in account creation', '1', '22', 'zen_cfg_select_option(array(\'true\', \'false\'), ', now());
INSERT INTO configuration (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, set_function, date_added) VALUES ('Require Referral', 'REFERRAL_REQUIRED', 'true', 'Require the Referral Source in account creation', '5', '6', 'zen_cfg_select_option(array(\'true\', \'false\'), ', now());

So, could anyone please be so kind as to tell me how to reverse this SQL patch? More to the point, why after running the patch do I get the 1062 Duplicate entry '765' for key 1 error?

I too am receiving this error after i've just installed this mod, however mine is "1062 Duplicate entry '1' for key 'PRIMARY'"
I receive it when i try and create an account

Couldnt edit my post but i've found a fix.

In /includes/modules/create_account.php (you may have this file in YOUR_TEMPLATE folder) i believe either by lack of instruction or concentration there was a block of code which i needed to delete.

Around line 329 you should have code that looks like this:

//rmh referral start
$query_insert= "insert into " . TABLE_CUSTOMERS_INFO . " (customers_info_id, customers_info_number_of_logons, customers_info_date_account_created, customers_info_source_id) values ('" . (int)$_SESSION['customer_id'] . "', '0', now(), '". (int)$source . "')";

$sql = "insert into " . TABLE_CUSTOMERS_INFO . "
                      (customers_info_id, customers_info_number_of_logons,
                       customers_info_date_account_created, customers_info_date_of_last_logon)
          values ('" . (int)$_SESSION['customer_id'] . "', '1', now(), now())"; 
  $db->Execute($query_insert);

$db->Execute($sql);

If you delete:

$sql = "insert into " . TABLE_CUSTOMERS_INFO . "
(customers_info_id, customers_info_number_of_logons,
customers_info_date_account_created, customers_info_date_of_last_logon)
values ('" . (int)$_SESSION['customer_id'] . "', '1', now(), now())";
It should work for you. If you examine the code you can see that the data is being inserted to the database twice.

Hope this helps people

Hi yeah, I meant to add a response to this last nigth but I was too tired by the tme I'd solved it. Like you, it turned out that another modification in my create_account.php was writing to the same table. In my case it was the 'COWA' mod. I just deleted the duplicate lines from the file and voila, the new mod worked perfectly.
