這篇文章主要介紹了Python實作將sqlite資料庫匯出轉成Excel(xls)表的方法,結合實例形式分析了Python針對sqlite資料庫的連接、讀取及使用寫入操作包(xlwt)產生Excel表的相關實作技巧,需要的朋友可以參考下
#本文實例講述了Python實作將sqlite資料庫匯出轉成Excel(xls)表的方法。分享給大家供大家參考，具體如下：
#1. 假設已經安裝有sliqte 函式庫的Python環境
我的是Python2.5
2. 下載python xls 寫入操作包(xlwt)並安裝
3.下面就是程式碼(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
如果沒錯，會在資料庫的目錄下產生同名的xls檔案
以上是Python中如何將sqlite匯出後轉成Excel(xls)表的範例詳解的詳細內容。更多資訊請關注PHP中文網其他相關文章！
