I created tables in MySQL Workbench as shown to make your diet healthier:

CREATE in TABLE command (  OrderID is NOT a null integer, OrderDato DEFAULT DATE null, Client ID INT DEFAULT null, LIMIT Ordre_pk PRIMARY KEY (OrdreID),  LIMIT Order_fk Foreign key (CustomerID) REFERENCES to customer (CustomerID))  ENGINE stands for InnoDB;

CREATE PRODUCT TABLE (  ProductID is NOT a null integer, Product Description VARCHAR(100) DEFAULT null, ProductColor VARCHAR(20) DEFAULT null, Null object STANDARD INT, LIMIT Product_pk KEY PRIMARY (ProductID))  ENGINE=InnoDB;

CREATE TABLE Orderlinje (  NOT int null command The product is NOT int null, Antall Beststilt INT DEFAULT null, LIMITATION Ordrelinje_pk PRIMARY KEY (order, product), KEY LIMITATION orderlinje_fk overseas (Order) LINKS Order (OrderID),  LIMIT Ordrelinje_fk1 FOREIGN KEY (Product) REFERENCES Product (ProductID))  ENGINE=InnoDB;

So when I try to insert values ​​into the ORDRELINJE table, my partner and I get:

Error code: 1452. Cannot add row to update child element: Outer strict secret failedvalues ​​(srdjank.Ordrelinje, CONSTRAINT Orderlinje_fk) . FOREIGN KEY (order) (orderID)) references Seen order

I posted this here in the thread, but it didn’t work.Am I missing something or do I have an idea, is there something to do?

In MySQL, Enter A Row From A Child Table Without A Table Containing The Row, Using The Parent Insert Table For

Example of row on top of child table without table with row linked to parent MySQL

1. Create a parent table P1 and a child table C1.

mysql> Create table p1(id key integer name key, OK, varchar(100));Query lines 0 (0 affected.09 create sec)mysql> table c1 (cid integer key pid predominant, foreign integer mandatory, references (pid) p1(id));Query strings ok, 0 affected (0.09s)

2. Inserting data from the parent table into the child table and subtracting errors in the child table, since there is no data in the parent table.

mysql> insert p1 dialog into OK, (1,'a');query affected 1 row second at (0.03.)mysql> when in addition p1(2, 'b');Query values ​​OK, I assigned the string sec(0,01.In )mysql> add values ​​c1(2,5);ERROR 1452 (23000): Cannot add child message to row: outer constraint 1 ("test" fails. LIMIT `c1_ibfk_1` `c1`, FOREIGN KEY (`pid`) `p1` references SET (`id`) )

mysql> FOREIGN_KEY_CHECKS 0;Query = OK, 0 rows affected (0.00 seconds)mysql> insert input values ​​c1(3,5);Request OK, line #1 (assigned 0.02s)mysql>SET FOREIGN_KEY_CHECKS implies 1;Query OK, affected (0.00 0 lines s)

4. After enabling foreign key validation, look for the new query error.

mysql> c1 values ​​everywhere (4.5);INSERT error 1452 (23000): unable to add update or child row: foreign technical constraint not (`test` works. CONSTRAINT `c1`, `c1_ibfk_1` KEY foreign (`pid`) refers to `p1` (`)) id` 

mysql> select 2 . from c1;+-----+------+| | PID ID |+-----+------+| | 3 a |+-----+------+1 row of pairs per set (0.00 seconds per solution)mysql>>p1;+----+------+| Login Setting |+----+------+| 1 | a || 2 | gymnasium |+----+------+2 lines in adjustment (0.00 Content="#da532c" sec)
