sqlite - Python's sqlite3 module not consolidating my database changes -

-


attempting populate database latlon weather data future consultation. doing via sqlite3 python module.

at moment, able create table (a resulting .db file visible after program execution). able consult rows after insertion, i'm sure cursor.execute lines working.

unfortunately, after program execution, upon consulting database "select * table" statement, nothing appears (even though same command worked beforehand, while program executed). in fact, when dumping sqlite3 file, create statement.

what wrong? no errors or warnings.

the code itself:

#!/usr/bin/python import sys import numpy netcdf4 import dataset import sqlite3  # config variables. n = 0 e = -30 s = -30 w = -60  ncfile = sys.argv[1]; ncdata = dataset(ncfile,'r',format='netcdf4')  sst = ncdata.variables['sea_surface_temperature'] lat = ncdata.variables['lat'] lon = ncdata.variables['lon']  # data reshaping. lat = lat[:] lon = lon[:] sst = sst[:]  c_lat = numpy.argwhere((lat <= n) & (lat >= s)) c_lon = numpy.argwhere((lon <= e) & (lon >= w))  conn = sqlite3.connect('sst.db') c = conn.cursor()  # create database table. c.execute("""create table current(lat real, lon real, sst real)""")  sqlite3.register_adapter(numpy.float64, float) sqlite3.register_adapter(numpy.float32, float) lati in c_lat:     loni in c_lon:         latn = lati[0]         lonn = loni[0]         lat_db = lat[latn]         lon_db = lon[lonn]         sst_db = sst[0,lonn][latn]          values = (lat_db,lon_db,sst_db)         if type(sst_db) != numpy.float64:             continue          c.execute("insert current values(?,?,?)",values)  # test if data inserted. (it is!) c.execute("select * current") print c.fetchall()

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
