CREATE PROCEDURE spInsertEmployee 
(
IN Employee_Name nvarchar(20), 
IN Employee_Surname nvarchar(20), 
IN Department_Name nvarchar(20)
)
BEGIN
declare Department_Id INT;

select Id into Department_Id from tblDepartment WHERE tblDepartment.Department_Name=Department_Name;
insert into tblVeri(Employee_Name,Employee_Surname,Department_Id)     VALUES(Employee_Name,Employee_Surname,Department_Id);

END;
