下面的 Python 程序显示了如何从前面创建的 COMPANY 表中获取并显示记录：

#!/usr/bin/python import sqlite3 conn = sqlite3.connect('test.db') c = conn.cursor() print "Opened database successfully"; cursor = c.execute("SELECT id, name, address, salary from COMPANY") for row in cursor: print "ID = ", row[0] print "NAME = ", row[1] print "ADDRESS = ", row[2] print "SALARY = ", row[3], "\n" print "Operation done successfully"; conn.close()

上述程序执行时，它会产生以下结果：

Opened database successfully ID = 1 NAME = Paul ADDRESS = California SALARY = 20000.0 ID = 2 NAME = Allen ADDRESS = Texas SALARY = 15000.0 ID = 3 NAME = Teddy ADDRESS = Norway SALARY = 20000.0 ID = 4 NAME = Mark ADDRESS = Rich-Mond SALARY = 65000.0 Operation done successfully UPDATE 操作

下面的 Python 代码显示了如何使用 UPDATE 语句来更新任何记录，然后从 COMPANY 表中获取并显示更新的记录：

#!/usr/bin/python import sqlite3 conn = sqlite3.connect('test.db') c = conn.cursor() print "Opened database successfully"; c.execute("UPDATE COMPANY set SALARY = 25000.00 where ID=1") conn.commit() print "Total number of rows updated :", conn.total_changes cursor = conn.execute("SELECT id, name, address, salary from COMPANY") for row in cursor: print "ID = ", row[0] print "NAME = ", row[1] print "ADDRESS = ", row[2] print "SALARY = ", row[3], "\n" print "Operation done successfully"; conn.close()

上述程序执行时，它会产生以下结果：

Opened database successfully Total number of rows updated : 1 ID = 1 NAME = Paul ADDRESS = California SALARY = 25000.0 ID = 2 NAME = Allen ADDRESS = Texas SALARY = 15000.0 ID = 3 NAME = Teddy ADDRESS = Norway SALARY = 20000.0 ID = 4 NAME = Mark ADDRESS = Rich-Mond SALARY = 65000.0 Operation done successfully DELETE 操作

下面的 Python 代码显示了如何使用 DELETE 语句删除任何记录，然后从 COMPANY 表中获取并显示剩余的记录：

#!/usr/bin/python import sqlite3 conn = sqlite3.connect('test.db') c = conn.cursor() print "Opened database successfully"; c.execute("DELETE from COMPANY where ID=2;") conn.commit() print "Total number of rows deleted :", conn.total_changes cursor = conn.execute("SELECT id, name, address, salary from COMPANY") for row in cursor: print "ID = ", row[0] print "NAME = ", row[1] print "ADDRESS = ", row[2] print "SALARY = ", row[3], "\n" print "Operation done successfully"; conn.close()

上述程序执行时，它会产生以下结果：

Opened database successfully Total number of rows deleted : 1 ID = 1 NAME = Paul ADDRESS = California SALARY = 20000.0 ID = 3 NAME = Teddy ADDRESS = Norway SALARY = 20000.0 ID = 4 NAME = Mark ADDRESS = Rich-Mond SALARY = 65000.0 Operation done successfully
