[python sqlite3查看数据库所有表(table)]

#coding:utf-8

import sqlite3

'''
sqlite3存在系统表sqlite_master,结构如下：
sqlite_master(
    type TEXT,      #类型:table-表,index-索引,view-视图
    name TEXT,      #名称:表名,索引名,视图名
    tbl_name TEXT,
    rootpage INTEGER,
    sql TEXT
    )
'''
#查看某数据库中所有表
def GetTables(db_file = 'main.db'):
    try:
        conn = sqlite3.connect(db_file)
        cur = conn.cursor()
        cur.execute("select name from sqlite_master where type='table' order by name")
        print cur.fetchall()
    except sqlite3.Error, e:
            print e
'''
#查看表结构
cur.execute("PRAGMA table_info(T_Person)")
print cur.fetchall()
'''

2."describe table"
两种方法
-
cursor.execute("PRAGMA table_info(tablename)")
print cursor.fetchall()
--
from sqlite3 import dbapi2 as sqlite
cur.execute("SELECT * FROM SomeTable")
col_name_list = [tuple[0] for tuple in cur.description]
