create table Employees
(
EmployeeID INT IDENTITY (1,1) PRIMARY KEY NOT NULL,
EmployeeName VARCHAR(255) NOT NULL,
EmployeeUsername VARCHAR(255) NOT NULL,
EmployeeEmail VARCHAR(255) NOT NULL,
GroupID INT FOREIGN KEY REFERENCES TypeOfGroup(GroupID),
Password VARCHAR(255) NOT NULL
);
create table TypeOfGroup
(
GroupID INT IDENTITY(1,1) PRIMARY KEY NOT NULL,
TypeGroup VARCHAR(255) NOT NULL,
Permission CHAR(1) NOT NULL
);
Question: I have a foreign key and wanted to make a connection with another table as I do this to insert into.
My foreign key is 'GROUPID'.
Try this...
insert into TypeOfGroup( TypeGroup, Permission) values ('hr', 1)
"this 1 is used for bit which is a data type in sql server 1 for true and 0 for false"
insert into Employees (EmployeeName, EmployeeUsername, EmployeeEmail,
GroupID, Password) values ('bruno', 'bruno', 'bruno#gmail.com', 1, 'urPassword')
and 1 in the 2nd query is primary of typeofgroup table.

I have some tables that will not be made when using the source command and I can't seem to find out what is wrong with them
I used MariaDB [cpt238]> source E:\database\create.sql
and got this

I have a problem.
I created a MySQL schema with the MySQL Workbench.
But there is a error message.
A comma or closing bracket was expected. (near "VISIBLE" at position 288)
Unexpected start of statement. (near "`ShopID`" at position 330)
Unrecognised statement type. (near "ASC" at position 339)
As I said I created the scheme via the MySQL workbench. But what is wrong ?
Note: PK = Primary Key; FK = Foreign Key.
Fact table:
Contaminants (TimeID (PK/FK), ShopID (PK/FK), FoodID (PK/FK), substance, quantityPerOunce)

The above three sqlite3 tables contain foreign keys. The problem is the deletion of a key in the upper table type. When I try do delete I get 'FOREIGN KEY constraint failed' Error. Deleting a from the lowest table object_user_owner before deleting a type works. I think sqlite does not check any recursive cascade constraints. Does anyone have experienced this too or is anything wrong with my design?

CONSTRAINT res_customer_type UNIQUE (CustomerID, CustomerType) REFERENCES Customer(CustomerID, CustomerType)

The last line keeps coming up as missing parenthesis (around the references line along the unique constraint). I'd like to specify the unique constraint to create a subtype table under customer.
P.S I'm using oracle sql, thanks
You use the Unique keyword where you should use the Foreign key keyword.
CONSTRAINT res_customer_type UNIQUE (CustomerID, CustomerType) REFERENCES Customer(CustomerID, CustomerType)
should be
CONSTRAINT res_customer_type FOREIGN KEY (CustomerID, CustomerType) REFERENCES Customer(CustomerID, CustomerType)
I am importing database and i got an error
1062 - Duplicate entry '1' for key PRIMARY.
i tried to upload table individually But it gives me error for those table which have at least one row.
i don't want to delete any record of any table.
here is one table which is giving error.

You do not need to specify the record id (with the exception of some circumstances when you need to keep the connection between records in different tables). Try using this query:
INSERT INTO wpbeta_aff_affiliates (name, email, from_date, thru_date, status, type) VALUES ('Direct', NULL, '2013-07-03', NULL, 'active', 'direct');
