import MySQLdb 

# Open database connection 

db = MySQLdb.connect("localhost","testuser","test123","TESTDB" ) 

# prepare a cursor object using cursor() method 

cursor = db.cursor() 

# Prepare SQL query to INSERT a record into the database. 

sql = "SELECT * FROM EMPLOYEE / 

 WHERE INCOME %d" % (1000) 

try: 

 # Execute the SQL command 

 cursor.execute(sql) 

 # Fetch all the rows in a list of lists. 

 results = cursor.fetchall() 

 for row in results: 

 fname = row[0] 

 lname = row[1] 

 age = row[2] 

 sex = row[3] 

 income = row[4] 

 # Now print fetched result 

 print "fname=%s,lname=%s,age=%d,sex=%s,income=%d" % /
