用法:
executemany(sql, seq_of_parameters)
針對序列
seq_of_parameters
中找到的所有參數序列或映射執行參數化 SQL 命令。sqlite3
模塊還允許使用迭代器產生參數而不是序列。import sqlite3 class IterChars: def __init__(self): self.count = ord('a') def __iter__(self): return self def __next__(self): if self.count > ord('z'): raise StopIteration self.count += 1 return (chr(self.count - 1),) # this is a 1-tuple con = sqlite3.connect(":memory:") cur = con.cursor() cur.execute("create table characters(c)") theIter = IterChars() cur.executemany("insert into characters(c) values (?)", theIter) cur.execute("select c from characters") print(cur.fetchall()) con.close()
這是一個使用生成器的簡短示例:
import sqlite3 import string def char_generator(): for c in string.ascii_lowercase: yield (c,) con = sqlite3.connect(":memory:") cur = con.cursor() cur.execute("create table characters(c)") cur.executemany("insert into characters(c) values (?)", char_generator()) cur.execute("select c from characters") print(cur.fetchall()) con.close()
