这篇文章主要介绍了Python实现将sqlite数据库导出转成Excel(xls)表的方法,结合实例形式分析了Python针对sqlite数据库的连接、读取及使用写操作包(xlwt)生成Excel表的相关实现技巧,需要的朋友可以参考下
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
3. 下面就是代码(db2xls.py):
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, 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
