Need help with this SQL problem. Please as soon as possible. Thanks people of chegg.

• Run sqlplus iggy/oracle. (It is assumed that you have already run the LoadDB.sql script last week that built the required user and tables.)
• Type SPOOL c:\cis4210\M2spool.txt .
• Write a single SQL statement that lists all suppliers supplying only hammers using the difference operation (MINUS).

• When finished, stop the spooling and exit the program. (You may edit the spool file for clarity if you wish.)

Data is:

SQL> DESCRIBE iggy.part; Name Null? Type ----------------------------------------- -------- ---------------------------- PARTNAME NOT NULL VARCHAR2(32)

SQL> SELECT * FROM iggy.part;

PARTNAME -------------------------------- HAMMER NAIL

SQL> DESCRIBE iggy.supplier; Name Null? Type ----------------------------------------- -------- ---------------------------- SUPPLIERNAME NOT NULL VARCHAR2(32)
