sql = ' SELECT ' name ' from test where ' sort ' = '%s '
exsql = sql% (' python ')
Count = Cur.execute (exsql)
For row in cur:

print ' cursor move to top: '
Cur.scroll (0, ' absolute ')

row = Cur.fetchone ()
While row isn't None:
Print row
row = Cur.fetchone ()

print ' cursor move to top: '
Cur.scroll (0, ' absolute ')

many = Cur.fetchmany (count)
Print many

Def deletedb ():
sql = ' Delete from test where ' sort ' = '%s '
exsql = sql% (' python ')
Cur.execute (Exsql)
Conn.commit ()
Return ' Delete Success '
