I would like to connect to dashDB from the .py program on Bluemix.

dsn='sqldb'# ODBC User Dataset SQLDB definition required
usr = 'dash013754'
psw = 'XXXXXXXXXX'
try:
    conn=ibm_db.connect(dsn,usr,psw)
except:     
    print "no connection:", ibm_db.conn_errormsg()
else:
    print "The connection was successful" 

def selectSQLDB():
    now=datetime.datetime.today()
        print now
    sql="SELECT NAME FROM SYSIBM.SYTABLES"
    stmt = ibm_db.prepare(conn,sql)
    body="body of Tweet"
    ibm_db.bind_param(stmt,1,body)
    try:
        ibm_db.execute(stmt)        
#       stmt=ibm_db.exec_immediate(conn,sql)     
    except:
        print "Transaction couldn't be completed:", ibm_db.stmt_errormsg()
        print stmt
        print sql
    else:
        print "Transaction complete."
