So my MySQL database is behaving a little bit wierd. This is my table:
Name shares id price indvprc
cat 2 4 81 0
goog 4 4 20 20
fb 4 9 20 20
I’m getting this #1062 error when I try to insert into the table. So I looked into it further and realized that when I try to insert values into the table, in which the name and shares values are the same, it will return the #1062 error. For example, If i inserted:
fb 4 6 20 20
It would return an error. But if i changed the shares number to 6, it would run fine. Is it because of one of my columns that could be unique, or is it just something with mysql?

You need to remove shares
as your PRIMARY KEY
OR UNIQUE_KEY

Use SHOW CREATE TABLE your-table-name
to see what column is your primary key.

- Make sure
PRIMARY KEY
was selectedAUTO_INCREMENT
. - Just enable Auto increment by :
ALTER TABLE [table name] AUTO_INCREMENT = 1
- When you execute the insert command you have to skip this key.

I solved it by changing the «lock» property from «shared» to «exclusive»:
ALTER TABLE `table`
CHANGE COLUMN `ID` `ID` INT(11) NOT NULL AUTO_INCREMENT COMMENT '' , LOCK = EXCLUSIVE;

What is the exact error message? #1062 means duplicate entry violating a primary key constraint for a column — which boils down to the point that you cannot have two of the same values in the column. The error message should tell you which of your columns is constrained, I’m guessing «shares».

Probably this is not the best of solution but doing the following will solve the problem
Step 1: Take a database dump using the following command
mysqldump -u root -p databaseName > databaseName.db
find the line
ENGINE=InnoDB AUTO_INCREMENT="*****" DEFAULT CHARSET=utf8;
Step 2: Change *******
to max id of your mysql table id. Save this value.
Step 3: again use
mysql -u root -p databaseName < databaseName.db
In my case i got this error when i added a manual entry to use to enter data into some other table. some how we have to set the value AUTO_INCREMENT
to max id using mysql command

Repair the database by your domain provider cpanel.
Or see if you didnt merged something in the phpMyAdmin

The DB I was importing had a conflict during the import due to the presence of a column both autoincrement and primary key.
The problem was that in the .sql file the table was chopped into multiple «INSERT INTO» and during the import these queries were executed all together.
MY SOLUTION was to deselect the «Run multiple queries in each execution» on Navicat and it worked perfectly

Do not mix SQLAlchemy commands with Python’s Try-Except. SQL will keep trying regardless, and the error will only show later in your program flow.

I had this error from mySQL using DataNucleus and a database created with UTF8 — the error was being caused by this annotation for a primary key:
@PrimaryKey
@Unique
@Persistent(valueStrategy = IdGeneratorStrategy.UUIDSTRING)
protected String id;
dropping the table and regenerating it with this fixed it.
@PrimaryKey
@Unique
@Persistent(valueStrategy = IdGeneratorStrategy.UUIDHEX)
protected String id;

Ошибка вида #1062 — Duplicate entry ‘1’ for key ‘PRIMARY’, может возникать при переносе на другой хостинг, у меня возникла, когда я переносил сайт на oscommerse…будем решать ее в этой статье…
Duplicate entry ‘1’ for key ‘PRIMARY’ — то есть вы пытаетесь создать то, что уже создано(в phpmyadmin). Обычно такая ошибка возникает, когда вы поверх уже установленной базы (БД) движка, пытаетесь сверху накинуть примерно такую же базу, но таблицы к примеру уже такие были созданы и поэтому вылазит такая ошибка.
Открываем файл БД в программе notepad++ и меняем INSERT INTO на REPLACE INTO. Теперь мы не будем создавать то, что уже есть, а будем перезаписывать. Теперь заливаем еще раз эту БД и ошибка должна исчезнуть.

Ответ MySQL:
#1062 — Duplicate entry ‘1’ for key ‘PRIMARY’
Так как в базах данных я полный чайник, пришлось копаться в интернете в поисках решения. На форумах довольно много записей от людей с подобной проблемой, но нигде нет четкого ответа – сделай вот так и так.
В общих чертах я проблему понял, но вот как ее решить было неясно. На всех форумах, где встречалось описание подобной ошибки, люди писали, что она возникает при попытке добавить записи из одной базы данных в уже существующую другую.
Но я импортировал базу данных в пустые таблицы, более того, таблицы создавались в процессе импорта.
Решил проблему с ошибкой «#1062 — Duplicate entry ‘1’ for key ‘PRIMARY’» следующим образом:
Заменил в таблицах базы данных команду INSERT INTO на REPLACE INTO. В тексте ошибки, который я привел выше вы можете посмотреть в каком месте таблицы располагаются эти слова (выделил жирным).
По умолчанию, с помощью директивы insert база пыталась вставить значения в таблицу, но почему-то, находила дублированный key ‘PRIMARY’ и не могла вставить данные (как она их находила, я так и не разобрался). Директива replace заставила базу заменять данные при совпадении значений, не обращая внимания на прошлые записи.
Заменить эту директиву можно открыв сам файл базы данных с помощью текстового редактора – эта команда стоит перед блоком каждой таблицы. Открываете базу данных в текстовом редакторе, например, Akelpad и меняете все команды INSERT INTO на REPLACE INTO.
В моем же случае, получилось сделать проще – я по новой сделал экспорт таблицы на старом хостинге и в настройках экспорта установил этот самый REPLACE вместо INSERT.
Duplicate Entry error is a very common error that has been experienced by users working with databases. Users have reported that the error has commonly occurred when using the SQL. The error appears when updating the tables. Furthermore, the error has occurred in several scenarios which include using Laravel, PHP, Atlassian, Joomla, and similar web development and databases. Now in this article, the objective is to give you important information regarding the error and to give you some methods by which you can fix the issue by yourself in no time. But before let’s go through its causes.
Causes of Duplicate Entry Error Problem Issue
While researching about the error and its possible solution we come up with some very common users that have been reported by the users. The Duplicate Entry error appears because of multiple reasons depending like if you are working with SQL possible the error comes because of the duplicate key, unique data field, or data type -upper limit. Also if the table indexes are corrupted then also the error seems to appear. However, the error also occurs due to mistakes in the codes or the way the user is updating or modifying the table.
- Duplicate key or entries
- Unique data field
- Data type -upper limit
- Table indexes are corrupted
- Mistakes in the codes
Similar Types of Duplicate Entry Error Problem Issue
- MySQL error 1062 duplicate entry ‘0’ for key ‘primary’
- MySQL for key ‘primary auto_increment
- #1062 – duplicate entry ‘1’ for key ‘primary’ PHPMyAdmin
- ‘0’ for key ‘primary Codeigniter
- Duplicate entry 255 for key ‘primary
- 82 for key primary
- Duplicate entry ‘4294967295’ for key ‘primary
- #1062 40 for key primary
In this section, we will try to cover some methods that you can try to resolve the Duplicate Entry Error. The following are the methods we will go through. Since we do not know the actual cause of the issue we will be giving you solutions according to the scenarios.
1. The Value Already Exist (Duplicate Value)
Now the #1062 – duplicate entry ‘1’ for key ‘primary’ Error may occur when the data or value which you are trying to insert already exists in the Primary key. Furthermore, it is important to know that the Primary key does not accept duplicate entries. To resolve this you can do the below steps.
- STEP 1. Put the Primary Key Colum as to be auto increment
- STEP 2. Use the below syntax
ALTER TABLE ‘table_name’ ADD ‘column_name’ INT NOT NULL AUTO_INCREMENT PRIMARY KEY;
**NOTE: You can ignore the Primary key column while inserting values.
Alternatively,
you can put NULL vale to Primary Key which in turn automatically generates sequence numbers.
2. Unique Data Filed
The error also appears when an existing table has been set to unique. So when you try to add any column the error appears. So the simple fix to this duplicate entry for key ‘primary’ issue is to create a new column but don’t set it to the Unique field. Insert whatever data you wish to insert and the set is as unique if you want to.
3. Data Limit Out Of Range
The error also appears when if you have been using the auto_increment function and the data exceeds the limit of auto_increment function the #1062 – duplicate entry ‘0’ for key ‘primary’ error appears. Suppose you have assigned the primary key column as something. And the limit of the auto_increment is set to a max of 127. Now when you enter a new record whose id is more than 127 the error will emerge. To fix this follow the steps.
- STEP 1. We can resolve the issue by modifying the index field. You may use any of the following signed/unsigned INT/ BIGINT
- STEP 2. Use the below command to increase the maximum range
ALTER TABLE ‘table_name’ MODIFY ‘column_name’ INT UNSIGNED NOT NULL AUTO_INCREMENT;
- STEP 3. Also if you want to retrieve the recently incremented value, the below command
mysql> SELECT LAST_INSERT_ID();
4. Creating a New Database & Importing
If you have tried the above methods and the duplicate entry 0 for key primary error still persists, try the below step to fix the issue.
- STEP 1. Firstly backup your database using the below command
mysqldump database_name > database_name.sql
- STEP 2. Once the backup is done, drop the database
DROP DATABASE database_name;
- STEP 3. Now recreate the database, by using the below command
CREATE DATABASE database_name;
- STEP 4. Now that you have created the database import using the below command
mysql database_name < database_name.sql;
- STEP 5. Now check if the duplicate entry ‘1’ for key ‘primary’ error still occurs
5. When Importing Table from Database in PHPmyadmin
The error has been seen when the user tries to import the exported tables in PHPMyAdmin the duplicate entry for key primary error seems to appear. Follow the steps to do it the right way.
- STEP 1. When you are exporting your SQL database in PHPMyAdmin, use the custom export method
- STEP 2. In the export, method choose Custom- display all possible options
- STEP 3. In the options instead of selecting any of the insert options, choose update
- STEP 4. Using this way will prevent any kind of duplicated inserts to get rid of remove duplicate entry in excel error.
6. Duplicate Username
One of the users has been facing the issue because the database does not allow duplicate usernames. So kindly make sure that the username is unique. To fix this how to remove the duplicate entry in excel issue follow the steps.
- STEP 1. In order to resolve the issue, you have to find find the duplicate usernames, which can be done using the following command
SELECT username FROM #__users GROUP BY username HAVING COUNT(*) > 1
**NOTE: Instead of #_ use the prefix for your tables.
- STEP 2. Fix the 1062 duplicate entry 1 for key primary issue
7. Other Troubleshooting Points
- Error in WordPress Database: So one the cause why this duplicate entry 1 for key primary error occurs is because of adswsc_DbInstall. It is comparing the unequal table names.
- Update the Program: Make sure that if you are using any database application it is updated to the latest version.
- Crosscheck the code: Make sure that the code is accurate and without errors
Conclusion:
In this troubleshooting, we have seen various methods that are the solution to fix Duplicate Entry Error. The error may appear due to multiple reasons and we have tried to cover most of them. Furthermore, we have also talked about the possible causes that lead to this error.
