I have problem with adding foreign key in SQL Server 2012
create table Predracun
(
PredracunID int not null identity(1,1),
Iznos nvarchar(255),
Datum date,
Opis nvarchar(255)
)
create table Racun
(
RacunID int not null identity (1,1),
Sifra nvarchar(255),
BrojRacuna nvarchar(255)
)
create table Prijem
(
PrijemID int not null identity (1,1),
Datum date,
Opis nvarchar(255)
)
alter table Prijem
add constraint FK_PrijemPredracun
foreign key (PredracunID)
references Predracun (PredracunID)
added on this way
and I got error msg
Msg 1769, Level 16, State 1, Line 1 Foreign key 'FK_UredjajPrijem' references invalid column 'PrijemID' in referencing table 'Uredjaj'. Msg 1750, Level 16, State 0, Line 1 Could not create constraint. See previous errors.
The column PredracunID does not exist in table prijem. Therefore it can't be used as a foreign key.
Use below scripts:
CREATE TABLE Predracun
(
PredracunID int not null identity(1,1),
Iznos nvarchar(255),
Datum date,
Opis nvarchar(255)
PRIMARY KEY CLUSTERED
(
[PredracunID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
create table Racun
(
RacunID int not null identity (1,1),
Sifra nvarchar(255),
BrojRacuna nvarchar(255)
)
create table Prijem
(
PrijemID int not null identity (1,1),
PredracunID int,
Datum date,
Opis nvarchar(255)
)
alter table Prijem
add constraint FK_PrijemPredracun
foreign key (PredracunID)
references Predracun (PredracunID)
Note: Foreign key can be created only on either primary key column or unique key column from reference table. You were missing two things in your script.
