如何使用PHP在MySQL中查找丢失的日期?
echo "<tr> <th>Username</th><th>Date</th><th>Check In</th><th>Check Out</th> </tr>";
// get results1 from database
$result1 = mysql_query("SELECT * FROM attend WHERE user_name='ali' AND date BETW
我使用正则表达式搜索从文本文件中提取多行,并将结果赋值为字符串变量,假设为x。
我想逐行遍历字符串,就像处理打开的文本文件一样,但是python会遍历每个字符。
示例:
文本文件file.txt为:
ali ali ali
hello world
hello world
ali ali ali
我的代码是:
F = open(file.txt, 'r')
x = F.read()
y = re.search(r'ali.[\s\w+].', x, re.DOTALL)
for line in y:
print(line)
我正在尝试使用XCode版本12.0.1 (12A7300)构建AudioKit Cookbook,并收到以下错误: /Users/ali/Documents/Development/Cookbook/Cookbook/Cookbook/Recipes/Shaker.swift:13:30: Value of type 'CallbackLoop' has no member 'start'
/Users/ali/Documents/Development/Cookbook/Cookbook/Cookbook/Recipes/Shaker.swift:13:4
我有一个非常简单的存储过程,如下:
create or replace procedure WF_ALI is
ali number;
begin
ali :=2;
end;
以及如下所示的.NET代码:
GetDatabaseConnection();
sqlString = "WF_ALI";
command = new OracleCommand(sqlString, connection);
command.CommandType = System.Data.CommandType.StoredProcedure;
command.Parameters.Add("
我有一个由of4字段组成的数据库,例如:
name date Description Amount
Ali 05/04/2012 Salaries 2000$
Ali 08/04/2012 commission 100$
ALi 11/04/2012 Transport 100$
Ali 05/05/2012 Salaries 2000$
Ali 08/05/2012 commission 100$
ALi 11/05/2012
编辑:我非常抱歉造成的混乱,很明显我没有很好地解释,我需要将每个人每天的第一个和最后一个条目保存在我的csv中。
Basically what I have is:
3/4/2020 8:29 Ali
3/4/2020 8:35 Vlad
3/4/2020 11:47 Vlad
3/4/2020 11:47 Vlad
3/4/2020 11:49 Ali
3/4/2020 13:44 Vlad
3/4/2020 11:49 Ali
3/4/2020 14:15 Vlad
我写了这段代码来增加实例变量,但它不起作用,并说:
nil的未定义方法`+:NilClass (NoMethodError)
class Ali
@var1 = 2
def initialize
end
def getvar1
@var1 = @var1 + 2
return @var1
end
end
ali = Ali.new
puts ali.getvar1()
我想要更改以下内容:
% => \%
_ => \_
\ => \
例如:
1. ali% sdn bhd -> ali\% sdn bhd
2. ali_ sdn bhd -> ali\_ sdn bhd
3. ali\ sdn bhd -> ali\\ sdn bhd
下面是编写的代码:
<?php
$special_characters = array("%","_","\\");
$replace_special_characters = array("\\%","\\_
当我试图构建我的nextjs应用程序时,我会遇到这个错误。这个错误没有发生在我的应用程序的最后一个版本上,我没有使用任何配置文件,只是添加了几个动画库,当然,除了我编写的代码之外。
