Python实现将sqlite数据库导出转成Excel(xls)表的方法

import sqlite3 as sqlite
from xlwt import *
#MASTER_COLS = ['rowid','type','name','tbl_name','rootpage','sql']
def sqlite_get_col_names(cur,table):
  query = 'select * from %s' % table
  cur.execute(query)
  return [tuple[0] for tuple in cur.description]
def sqlite_query(cur,table,col = '*',where = ''):
  if where != '':
    query = 'select %s from %s where %s' % (col,where)
  else:
    query = 'select %s from %s ' % (col,table)
  cur.execute(query)
  return cur.fetchall()
def sqlite_to_workbook(cur,workbook):
  ws = workbook.add_sheet(table)
  print 'create table %s.' % table
  for colx,heading in enumerate(sqlite_get_col_names(cur,table)):
      ws.write(0,colx,heading)
  for rowy,row in enumerate(sqlite_query(cur,table)):
    for colx,text in enumerate(row):
      ws.write(rowy+ 1,text)
def main(dbpath):
  xlspath = dbpath[0:dbpath.rfind('.')] + '.xls'
  print "<%s> --> <%s>"% (dbpath,xlspath)
  db = sqlite.connect(dbpath)
  cur = db.cursor()
  w = Workbook()
  for tbl_name in [row[0] for row in sqlite_query(cur,'sqlite_master','type = 'table'')]:
    sqlite_to_workbook(cur,tbl_name,w)
  cur.close()
  db.close()
  if tbl_name !=[]: w.save(xlspath)
if __name__ == "__main__":
  # arg == database path
  main(sys.argv[1])

> python  <path>/db2xls.py  dbpath
