Python实现将sqlite数据库导出转成Excel(xls)表的方法

import sqlite3 as sqlitefrom 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, table, where)  else:    query = 'select %s from %s ' % (col, table)  cur.execute(query)  return cur.fetchall()def sqlite_to_workbook(cur, table, 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, colx, 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', 'tbl_name', '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])
