I don’t understand why I keep getting your 1061 error for duplicate keys in search engines when I have no duplicates. I’ve looked at other Stackoverflow articles on quite a few questions, most of them and got this problem when they had the same name for several different foreign keys. However, this does not apply to my whole case.

In short, I created a spreadsheet and task related accounts.Each book.id has several tasks associated with that particular post.This is a many-to-many relationship, meaning that there are several books associated with a specific task. And having a specific task, the ability to associate with many books.

So, between these many relationships, I have a table of x task books that can mediate. This table has its own primary key and two unusual keys. One is the workbook ID of the workbook tables and the username of the task table task. Hence, these are all foreign keys. In this way, I can link multiple tasks to multiple logs, such asEach is identified by its own pending ID in the booksxtasks table.

Run SQL script on server ERROR: 1061: error in duplicate key name ‘FK Tasks_TaskID_idx’ SQL code: CREATE INDEX `FK Tasks_TaskID_idx` ON` mydb`.`BooksxTasks` (` Tasks_TaskID` ASC)

  CREATE TABLE IF `mydb` does not exist. `BooksxTasks` (  `BooksxTasksID` INT UNSIGNED NOT NULL AUTO_INCREMENT,  `Books_BookID` INT UNSIGNED NOT NULL,  Tasks_TaskID TINYINT (2) NOT SIGNED NOT NULL,  PRIMARY KEY (`booksxtasksid`), RESTRICTION `FK Tasks_TaskID`    FOREIGN KEY (`Tasks_TaskID`)    REFERENCES `mydb`.`Tasks` (` TaskID`)    WITHOUT DELETE ACTION    WITHOUT UPDATE ACTION,  RESTRICTION `FK Books_BooksID`    FOREIGN KEY (`Books_BookID`)    REFERENCES `mydb`.`Books` (` BookID`)    WITHOUT DELETE ACTION    WITHOUT UPDATE ACTION)ENGINE = InnoDB;CREATE INDEX `FK Tasks_TaskID_idx` ON` mydb`.`BooksxTasks` (` Tasks_TaskID` ASC);CREATE INDEX `FK Books_BooksID_idx` mydb` in` BooksxTasks` (`Books_BookID` ASC); 

I also saw that all names were given subject to all constraints in the dataset. There were no duplicate names. So where did this double key error come from?

I got this error while creating foreign keys for a 2-column “association” table.

Step ( ) After creating both parents with PK, I created a child table.
Step (b) Then I tried to change it with two definitions of fk.

Regardless of the order in which I shot in step (b), I still get multiple consecutive errors in the second step.

ERROR 1061 (42000): Duplicate key name cm_article_contents

Create cm_articles tables
(
non-zero bigint article_id,
article_type_id bigint is not zero,
varchar (512) null header,
web_title varchar (128) null,
zero bridge varchar (256),
null varchar (256) notes,
Description varchar (512) null,
owner_id bigint null,
The start_dt timestamp is behind zero current_timestamp,
timestamp null end_dt,
Primary key (article_id)
);

Create table cm_contents
(
content_id bigint as opposed to null,
content_type_id bigint null,
Blob with zero content,
content_desc varchar (256) null,
non-zero bigint display_seq,
versioned symbol (1) non-zero expiration,
Primary key (content_id)
);

Add FK 1 constraint:
================
Change chair cm_article_contents
Add constraint cm_art_cont_1
The foreign key cm_article_contents (article_id) refers to cm_articles (article_id);

Add FK 2 constraint:
================
Modify the cm_article_contents table
Add constraint cm_art_cont_2
The foreign key cm_article_contents (content_id) refers to cm_contents (content_id);

MySQL: “Duplicate key name” error occurs when creating craps table with two foreign keys

Although MySQL is reporting an error on my website when creating a new table, which I cannot explain.

  CREATE TABLE products (    id INT NOT NULL,    PRIMARY KEY (id));CREATE TABLE Transfer Warehouse (    Season DATE TIME NOT ANNOTATION,    product1 INT NOT NULL,    product2 INT NOT NULL,    FOREIGN WAREHOUSE KEY TRAFFIC (product1) LINKS Products (id),    FOREIGN WAREHOUSE KEY MOVEMENT (product2) REFERENCES Products (id)); 

Error ERROR 1061 (42000): Duplicate key name "WarehouseMovements" . If I remove all foreign key constraints I succeed, but I want to make sure product1 and product2 are indeed pointing somewhere.

  CREATE TABLE products (    id INT NOT NULL,    PRIMARY KEY (id));CREATE TABLE Transfer Warehouse (    precious time NON-ZERO DATETIME,    product1 INT NOT NULL,    product2 INT NOT NULL,    INOCOUNTRY KEY IX_WarehouseMovements_product1 (product1) LINKS to products (id),    FOREIGN KEY IX_WarehouseMovements_product2 (product2) LINKS Products (id)); 

This is the index or FK name, not the table name. To create foreign keys for a table, see the documentation:

  [LIMITATION [character]] FOREIGN KEY[index_name] (index_col_name, ...)REFERENCES tbl_name (index_col_name, ...) 

index_name specifies the identifier for the foreign key. If specified, this fact will be ignored ifthe index for the unknown key is explicitly defined. Otherwise, ifMySQL allows index for foreign key, application uses index for index_nameIndex name.

  CREATE TABLE products (    id INT NOT NULL,    PRIMARY KEY (id));CREATE TABLE Transfer Warehouse (    evening TIME TIME IS NOT UP-TO-DATE,    product1 INT NOT NULL,    product2 INT NOT NULL,    RESTRICTION fk_product_1 FOREIGN KEY (product1) LINKS to products (id),    RESTRICTION fk_product_2 FOREIGN KEY (product2) LINKS to products (id)); 

  ALTER TABLE `cca_orders`ADD LIMITATION `item_id`FOREIGN KEY (`item_id`)` joshi_textile_db`Links. `cca_items_master` (` id`)DELETEON limit RESTRICTION UPDATED  I;
