[Tutor] A little example for MySql

I hadn't used the MySql bindings before, so I created a little example
that I thought was clearer than the one included with Andy Dustman's MySql
bindings for python. You may need to change the db, user and pass though.

import MySQLdb
import traceback
import sys

def tryordie(stmt):
	global cursor
	
	try:
		cursor.execute(stmt)
	except:
		print
		traceback.print_exc()
		mydb.close()
		sys.exit()


# begin main program here

try:
	mydb = MySQLdb.Connect(db='test', user='foo', passwd='bar')
	cursor = mydb.cursor()
except:
	print "\n\n"
	traceback.print_exc()
	sys.exit()
	
# try and create the table, but if it doesn't exist, don't harf

stmt = "CREATE TABLE COLORS (COLOR varchar(32) DEFAULT '' NOT NULL)"
try:
	cursor.execute(stmt)
except:
	pass

stmt = "DELETE FROM COLORS"
tryordie(stmt)

stmt = "INSERT INTO COLORS VALUES ('red')"
tryordie(stmt)

stmt = "INSERT INTO COLORS VALUES ('blue')"
tryordie(stmt)

stmt = "INSERT INTO COLORS VALUES ('yellow')"
tryordie(stmt)

# grand finale test

stmt = "select * from COLORS"
tryordie(stmt)
try:
	resultSet = cursor.fetchall()
	
	for i in xrange(0, len(resultSet)):
		print "Color number",i,"is", resultSet[i][0]
	
except:
	pass

mydb.close()
