This is the question to Project 3

1. Project 3 is about printing multiple records from DDI.LEDGER_VIEW using a PL/SQL LOOP

2. SPOOL your output to c:\CS4210\project3spool.txt

3. Set up a record variable in the DECLARE section using %ROWTYPE

4. SELECT all the fields in DDI.LEDGER_VIEW where ROOMNUM is 107

5. Use DBMS__OUTPUT.PUT_LINE to print the values for each field for each record.

6. Compile and run the procedure.

Here is the coding part so that so that you can do the question:
