如何过滤DateTime字符串，无sqlserver命令

// 假设DateTime字符串的格式为：YYYY-MM-DD HH:mm:ss
var dateTimeString = "2022-01-01 12:34:56";

// 将DateTime字符串转换为Date对象
var dateTimeParts = dateTimeString.split(/[- :]/);
var year = parseInt(dateTimeParts[0]);
var month = parseInt(dateTimeParts[1]) - 1;
var day = parseInt(dateTimeParts[2]);
var hour = parseInt(dateTimeParts[3]);
var minute = parseInt(dateTimeParts[4]);
var second = parseInt(dateTimeParts[5]);
var dateTime = new Date(year, month, day, hour, minute, second);

// 过滤DateTime字符串
var filteredYear = dateTime.getFullYear();
var filteredMonth = dateTime.getMonth() + 1;
var filteredDay = dateTime.getDate();
var filteredHour = dateTime.getHours();
var filteredMinute = dateTime.getMinutes();
var filteredSecond = dateTime.getSeconds();

// 输出过滤后的DateTime字符串
console.log(filteredYear + "-" + filteredMonth + "-" + filteredDay + " " + filteredHour + ":" + filteredMinute + ":" + filteredSecond);

from datetime import datetime

# 假设DateTime字符串的格式为：YYYY-MM-DD HH:mm:ss
dateTimeString = "2022-01-01 12:34:56"

# 将DateTime字符串转换为datetime对象
dateTime = datetime.strptime(dateTimeString, "%Y-%m-%d %H:%M:%S")

# 过滤DateTime字符串
filteredYear = dateTime.year
filteredMonth = dateTime.month
filteredDay = dateTime.day
filteredHour = dateTime.hour
filteredMinute = dateTime.minute
filteredSecond = dateTime.second

# 输出过滤后的DateTime字符串
print("{}-{}-{} {}:{}:{}".format(filteredYear, filteredMonth, filteredDay, filteredHour, filteredMinute, filteredSecond))
