是使用一个表格来存放当前和归档的记录最好，还是分别使用一个表格来存放归档和当前的记录？

这个问题的答案取决于具体的需求和数据量。下面给出两种解决方法的代码示例：

1. 使用一个表格存放当前和归档的记录：

import sqlite3

# 创建数据库连接
conn = sqlite3.connect('records.db')
cursor = conn.cursor()

# 创建表格
cursor.execute('''
    CREATE TABLE IF NOT EXISTS records (
        id INTEGER PRIMARY KEY,
        name TEXT,
        status TEXT
    )
''')

# 插入当前记录
cursor.execute('INSERT INTO records (name, status) VALUES (?, ?)', ('Record 1', 'Current'))
cursor.execute('INSERT INTO records (name, status) VALUES (?, ?)', ('Record 2', 'Current'))

# 插入归档记录
cursor.execute('INSERT INTO records (name, status) VALUES (?, ?)', ('Record 3', 'Archived'))
cursor.execute('INSERT INTO records (name, status) VALUES (?, ?)', ('Record 4', 'Archived'))

# 查询当前记录
cursor.execute('SELECT * FROM records WHERE status = ?', ('Current',))
current_records = cursor.fetchall()
for record in current_records:
    print(record)

# 查询归档记录
cursor.execute('SELECT * FROM records WHERE status = ?', ('Archived',))
archived_records = cursor.fetchall()
for record in archived_records:
    print(record)

# 关闭数据库连接
conn.close()

2. 分别使用一个表格存放归档和当前的记录：

import sqlite3

# 创建数据库连接
conn = sqlite3.connect('records.db')
cursor = conn.cursor()

# 创建当前记录表格
cursor.execute('''
    CREATE TABLE IF NOT EXISTS current_records (
        id INTEGER PRIMARY KEY,
        name TEXT,
        status TEXT
    )
''')

# 创建归档记录表格
cursor.execute('''
    CREATE TABLE IF NOT EXISTS archived_records (
        id INTEGER PRIMARY KEY,
        name TEXT,
        status TEXT
    )
''')

# 插入当前记录
cursor.execute('INSERT INTO current_records (name, status) VALUES (?, ?)', ('Record 1', 'Current'))
cursor.execute('INSERT INTO current_records (name, status) VALUES (?, ?)', ('Record 2', 'Current'))

# 插入归档记录
cursor.execute('INSERT INTO archived_records (name, status) VALUES (?, ?)', ('Record 3', 'Archived'))
cursor.execute('INSERT INTO archived_records (name, status) VALUES (?, ?)', ('Record 4', 'Archived'))

# 查询当前记录
cursor.execute('SELECT * FROM current_records')
current_records = cursor.fetchall()
for record in current_records:
    print(record)

# 查询归档记录
cursor.execute('SELECT * FROM archived_records')
archived_records = cursor.fetchall()
for record in archived_records:
    print(record)

# 关闭数据库连接
conn.close()

根据具体需求选择合适的方法。如果当前记录和归档记录的结构和字段完全相同，并且数据量不大，使用一个表格存放当前和归档的记录可能更方便。如果当前记录和归档记录的结构不同，或者数据量较大，分别使用两个表格存放归档和当前的记录可能更合适。
