请注意10,11,24行的代码，是本条博客的精华，逻辑并不难，就是有些小语法问题比较纠结，记录一下。

import json import sqlite3import reimport argparsedef Get(db_file): conn = sqlite3.connect(db_file) cur = conn.cursor() print("5555555") value1=(60)# this is must be () cur.execute("select * from exception where AGV_ID=(%s)" %(value1)) #cursor.execute("insert into exception values('%s', '%s','%s' ) " %(start_time ,ID ,infomation)) result= cur.fetchall() print("result:",result) for i in result: print(i) print("******************************888") def get_agv_id(db_file): try: conn = sqlite3.connect(db_file) cur = conn.cursor() cur.execute("select * from exception where AGV_ID=51") #print( cur.fetchall()) result= cur.fetchall() for i in result: print(i) except sqlite3.Error,e: print(e) if __name__ == '__main__': parser = argparse.ArgumentParser(description='check the information of db') #parser.add_argument('-h', '--help', help='Statistics for abnormal information') parser.add_argument('-n', '--name', help=' the db of name ') args = vars(parser.parse_args()) db_name = args['name'] print("db_name:",db_name) conn = sqlite3.connect('db_name') cursor = conn.cursor() Get('fitkits.db') get_agv_id('fitkits.db') conn.commit() conn.close() print('DONE!') print("666")

补充：python + sqlite3 基本操作

连接数据库

import sqlite3 # 连接数据库(如果不存在则创建)conn = sqlite3.connect('test.db')print("Opened database successfully") # 创建游标cursor = conn.cursor() ... # 关闭游标cursor.close()# 提交事物conn.commit()# 关闭连接conn.close()

创建表

...# 创建游标cursor = conn.cursor() # 创建表sql = 'CREATE TABLE Student(id integer PRIMARY KEY autoincrement, Name varchar(30), Age integer)'cursor.execute(sql) # 提交事物conn.commit()...

插入数据

...# 创建游标cursor = conn.cursor() # 插入数据sql = "INSERT INTO Student(Name, Age) VALUES(\'love\', 22)"cursor.execute(sql) # 插入数据 2data = ('love2', 2221) # or ['love2', 2221]sql = "INSERT INTO Student(Name, Age) VALUES(?, ?)"cursor.execute(sql, data) # 提交事物conn.commit()...

查询数据

...# 创建游标cursor = conn.cursor() # 查询数据sql = "select * from Student"values = cursor.execute(sql)for i in values: print(i) # 查询数据 2sql = "select * from Student where id=?"values = cursor.execute(sql, (1,))for i in values: print('id:', i[0]) print('name:', i[1]) print('age:', i[2]) # 提交事物conn.commit()...

其他操作

自增字段起始位置

# 设置起始值为1update sqlite_sequence SET seq = 0 where name = '表名';# 设置全部表起始值为默认值delete from sqlite_sequence where name='TableName'; --注意表名区分大小写

以上为个人经验，希望能给大家一个参考，也希望大家多多支持。如有错误或未考虑完全的地方，望不吝赐教。
