To subject table I add a record:

Now, I want to create a table: questionsinexam
CREATE TABLE `test`.`questionsinexam` (

Why I'm getting this error?
Thanks.
This constraint is definitely wrong:
CONSTRAINT `idExamSubject`
FOREIGN KEY (`idExamSubject`)
REFERENCES `test`.`exam` (`subjectID`)
ON DELETE NO ACTION
ON UPDATE NO ACTION,
Perhaps you intend:
CONSTRAINT `idExamSubject`
FOREIGN KEY (`idExamSubject`)
REFERENCES `test`.`subject` (`subjectID`)
ON DELETE NO ACTION
ON UPDATE NO ACTION,
Be sure that you create the target tables before you create the foreign key constraint. The referred to table needs to exist first (so the engine can validate types on the columns used for the foreign key).

Im getting the following error when i try to execute the last create query for the borrowedby table.
Error Code: 1822. Failed to add the foreign key constraint. Missing index for constraint 'holding_fk_1' in the referenced table 'holding'
have you tried to split the double foreign key? like this:
CONSTRAINT `holding_fk_1` FOREIGN KEY (`BookID`) REFERENCES `holding` (`BookID`) ON DELETE RESTRICT,
CONSTRAINT `holding_fk_1` FOREIGN KEY (`BranchID`) REFERENCES `holding` (`BranchID`) ON DELETE RESTRICT
what dms are you using? could be that you need to use another syntax to reference two foreign key at one or could be that it's not supported.
As said in the answer, just by changing order can fix it.
"Your code fails in Mysql 8.0.12 but runs fine in 8.0.22 As a workaround reverse the order of the columns: CONSTRAINT holding_fk_1 FOREIGN KEY (BranchID,BookID) REFERENCES holding (BranchID,BookID) ON DELETE RESTRICT, –

So I am very new to MySQL but I would like to think I that grasp a decent bit of it so far. I am struggling with the creation of the table PROJECT. I'm almost positive after my own research that it has something to do with my keys in the table. But I do not understand where the problem is or how to fix it.
The SQL queries below creates all tables for the project. I'm not sure of the problem because I only get the error code for the project for now. Any insight and advice on what causes this and how to rectify this in the code would be greatly appreciated.

Your problem lies essentially in the fact that you are trying to create a constraint to a non key column (because the referenced table has a double key).
In your table project you have:
CONSTRAINT `plocation`
FOREIGN KEY (`plocation`)
REFERENCES `dept_locations` (`dlocation`)
ON DELETE NO ACTION
ON UPDATE NO ACTION
dept_locations.dlocation is not a key ALONE (primary key), therefore the reason you are not able to create that constraint.
You need to make the constraint for both keys from the referenced table like this:
CONSTRAINT `plocation`
FOREIGN KEY (`pnumber`, `plocation`)
REFERENCES `dept_locations` (`dnumber`, `dlocation`)
ON DELETE NO ACTION
ON UPDATE NO ACTION
In this case you won't need the first constraint dnum as it is already referenced in dept_locations table.
Also note that you tables department and employee will not be created because one reference the other so you need to create the tables first without the constraints then apply the constraints like:
ALTER TABLE `employee` add
CONSTRAINT `dno`
FOREIGN KEY (`dno`)
REFERENCES `department` (`dnumber`)
ON DELETE NO ACTION
ON UPDATE NO ACTION;
Same for the department table and its constraint to employee
Normally you get the Error 1005 when it unable to create the foreign keys. When you are creating a foreign key constraint the parent table should be available in the database.
In your case 'employee' table has a FK to 'department' table but you are trying to create the 'employee' table before creating the 'department' table. Also the 'department' table has a FK back to 'employee' table. Therefore you are not able to create the 'department' table first. To solve this you may create the 'department' table first without FK to 'employee' table. Then create the 'employee' table and then alter the 'department' table with FK.
Here is the modified code for first two tables and follow the same pattern for rest if you get the same error.
CREATE TABLE IF NOT EXISTS `ebrasi1db`.`department` (
`dnumber` INT(11) NOT NULL,
`dname` VARCHAR(45) NULL DEFAULT NULL,

If I run this code all work well, but if uncomment last constraint, I got the following error:

It sounds like you may already have a constraint with that name on a different table in the database. Try changing the name of that constraint to something like "fk_transfer_component_id" and see if you still get the error.
