本文实例讲述了Python实现将sqlite数据库导出转成Excel(xls)表的方法。分享给大家供大家参考，具体如下：
1. 假设已经安装带有sliqte 库的Python环境
我的是Python2.5
2. 下载 python xls 写操作包(xlwt)并安装
下载地址: http://pypi.python.org/pypi/xlwt
3. 下面就是代码(db2xls.py)：

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]) |
4. 用法:

> python <path>/db2xls.py dbpath |
如果没错，会在数据库的目录下生成同名的xls文件
希望本文所述对大家Python程序设计有所帮助。
