請(qǐng)注意10,11,24行的代碼，是本條博客的精華，邏輯并不難，就是有些小語(yǔ)法問(wèn)題比較糾結(jié)，記錄一下。

補(bǔ)充：python + sqlite3 基本操作
連接數(shù)據(jù)庫(kù)
import sqlite3
# 連接數(shù)據(jù)庫(kù)(如果不存在則創(chuàng)建)
conn = sqlite3.connect('test.db')
print("Opened database successfully")
# 創(chuàng)建游標(biāo)
cursor = conn.cursor()
...
# 關(guān)閉游標(biāo)
cursor.close()
# 提交事物
conn.commit()
# 關(guān)閉連接
conn.close()
創(chuàng)建表
...
# 創(chuàng)建游標(biāo)
cursor = conn.cursor()
# 創(chuàng)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()
...
插入數(shù)據(jù)
...
# 創(chuàng)建游標(biāo)
cursor = conn.cursor()
# 插入數(shù)據(jù)
sql = "INSERT INTO Student(Name, Age) VALUES(\'love', 22)"
cursor.execute(sql)
# 插入數(shù)據(jù) 2
data = ('love2', 2221) # or ['love2', 2221]
sql = "INSERT INTO Student(Name, Age) VALUES(?, ?)"
cursor.execute(sql, data)
# 提交事物
conn.commit()
...
查詢數(shù)據(jù)
...
# 創(chuàng)建游標(biāo)
cursor = conn.cursor()
# 查詢數(shù)據(jù)
sql = "select * from Student"
values = cursor.execute(sql)
for i in values:
print(i)
# 查詢數(shù)據(jù) 2
sql = "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
# 設(shè)置起始值為1
update sqlite_sequence SET seq = 0 where name = '表名';
# 設(shè)置全部表起始值為默認(rèn)值
delete from sqlite_sequence where name='TableName'; --注意表名區(qū)分大小寫(xiě)
以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教。
