【Python】将sqlite数据库 转成 Excel(xls) 表

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 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   /db2xls.py    dbpath

        如果没错，会在数据库的目录下生成同名的xls文件
