Problem Use the attached script (see last page) to create the following Clinic database: patient medicine PNum INT(11) PName CHAR(50) Address CHAR (50) Gender CHAR (20) Age INT (11) prescription PNum INT(11) MedID INT(11) Quantity INT(11) Total DOUBLE MedID INT(11) MedName CHAR(50) Price DOUBLE PDate DATE Answer the following questions: 1. Add a constraint on medicine table, to prevent duplicating values for the MedName column. (15 points) 2. Add a constraint on prescription table, to set the MedID column as foreign key that points to MedlD column in the medicine table. (15 points) 3. Create a trigger "TRG_YourName" (example: TRG_Ahmed Naser) on table prescription, to calculate the Total column automatically if the user updates the Quantity (20 points) Note: Total=Quantity * Price if Quantity is less than 5, and Total=Quantity * Price X 0.8 otherwise 4. Create view "DetailsMar 17" to show PName, MedName and Total columns for all prescriptions issued during 05-March-2017 until 10-April-2017. (20 points) 5. Create a procedure "Pro1", that takes one string (P) as parameter and displays PName, Address and Gender of the patient whose PName equals to P. (10 points) 6. Create procedure GetPrescription" that takes one integer input (P) which represents Patient Number (PNum), and displays PNum, PName, MedName and PDate of all prescriptions issued for that Patient. (10 points) 7. Create procedure Income that takes the salary of an employee as input, and display the net income as output based on the following criteria: (10 points) Salary Income tax >=2000 10% >=1000 to 2000 5% =2000 10% >=1000 to 2000 5%
