Error 1061 (MYSQL Workbench) Multiplication of keys while creating an index
I cannot explain why I am getting error 1061 for duplicate keys when scanning when I have no clones. I looked at other Stackoverflow support articles on similar issues and most of them had this problem despite having the same name for several foreign methods. However, this does not apply to the mon dilemma.
In short, I used to create a whiteboard where books were linked to homework.Each book ID should have tasks that are associated only with a specific book.This is another plural relationship; H. There are many titles associated with the current problem. And a certain task will undoubtedly be associated with many books.
For many-to-many relationships, I have a table for x-task books that acts as an intermediary. This table has a unique primary key and two external buttons. One is the book table ID of the books table and the responsibility ID of the task table. Hence, both keys are foreign. This way I can associate many problems with several books, Each of which is recognized by its own unique identifier in the booksxtasks table.

What is the error code for SQL Server?
Sometimes when people all over the world try to restart “SQL Server Solutions”, we may receive the error “Windows could not stop the SQL Server service (MSSQLSERVER) on the local computer” along with a code error and description “Error 1061: Service. cannot receive control messages here at this time. “
I have also verified that all manufacturers respect any database limitations. There was no duplicate names. So where did our duplicate key error come from?
Why is MySQL creating table with two foreign keys fails?
ERROR: ERROR 1061 (42000): Duplicate key name “WarehouseMovements”. If I remove the foreign key constraints it works, but I definitely want product1 and product2 to actually point inward. The standard engine is InnoDB. What is wrong if the request is enabled?
I got this weird and valuable error while creating someone’s hands-on knowledge in A two-column “association” table.
Step (a) After creating the father and PC, I created the corresponding child table.
Step (b) Then e tried to change this with 2 definitions of FK.
Regardless of the order in which I might try them in step (b), I always buy the following error for an additional constraint
ERROR 1061 (42000): Duplicate address for key ‘cm_article_contents’
Create the cm_articles table
article_id bigint is less than zero,

Varchar (256) null,

Create a poker table cm_contents
non-zero content_id bigint,

Blob with zero content,
content_desc varchar (256) null,
display_seq bigint definitely sucks,
the default versioned character (1) ‘n’ is not zero,

Add FK 1 constraint:
Modify the cm_article_contents table
Add constraint cm_art_cont_1
Foreign key cm_article_contents (article_id) from refers to cm_articles (article_id);
Why is MySQL server not connecting to localhost?
I’m having trouble visiting MySQL when connecting using a localhost connection on the standard port 3306. I had issues like “Error 2003” and “Unable to connect to MySql server on localhost (10061) on the market.”
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: Creating a dining table with two foreign keys fails due to a duplicate name key error
When trying to create a new table, MySQL throws an error that I cannot explain.
CREATE TABLE products ( id INT NOT NULL, PRIMARY KEY (id));CREATE TABLE Transfer Warehouse ( NON-ZERO DATETIME working hours, 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 1061 (42000): Duplicate key name "WarehouseMovements" . If I remove foreign key constraints I am successful, but I want to help make sure product1 and product2 point to a dot.
CREATE TABLE products ( id INT NOT NULL, PRIMARY KEY (id));CREATE TABLE Transfer Warehouse ( DATETIME NOT NULL time, product1 INT NOT NULL, product2 INT NOT NULL, FOREIGN KEY IX_WarehouseMovements_product1 (product1) LINKS to products (id), FOREIGN KEY IX_WarehouseMovements_product2 (product2) LINKS Products (id));
This is a checklist or FK name, not a job name. See Create-table-external-keys. Documentation:
[LIMITATION. [symbol]]. FOREIGN. KEY[index_name]. (index_col_name, ....)REFERENCES tbl_name (index_col_name, ...)
index_name usually means foreign key identifier. If it helped, it will be ignored ifan index is explicitly defined to obtain a foreign key. Otherwise, ifMySQL and create the required index for the foreign key, it can be index_name forIndex name.
CREATE TABLE products ( id INT NOT NULL, PRIMARY KEY (id));CREATE TABLE Transfer Warehouse ( DATETIME NOT NULL time, 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));
