PHP PDO MySQL IN (?,?,?

由 空扰寡人 提交于 2020-02-20 05:32:46
问题 I want to write a MySQL statement like: SELECT * FROM someTable WHERE someId IN (value1, value2, value3, ...) The trick here is that I do not know ahead of time how many values there will be in the IN(). Obviously I know I can generate the query on the go with string manipulations, however since this will run in a loop, I was wondering if I could do it with a PDO PreparedStatement. Something like: $query = $PDO->prepare('SELECT * FROM someTable WHERE someId IN (:idList)'); $query->bindValue('

How can I get outside foreach loop value in this situation?

问题 I am trying to call all the value from a foreach loop from mysql data, and use there value input into another mysql select statement. Look at my code below. It only can gather one value. I was thinking to use the first foreach loop include the whole section, however, since foreach value is individual, and I need explode array for the PDO prepare. So, at last, I want to know a way to get all value from the outside foreach loop. Appreciate. //mysql connection code, remove because it is not

php连接数据库有MySQLi和PDO两种方法 以下以PDO为例 一、创建数据库表(students) 二、连接数据库(db.php) $dsn:数据库连接服务器，数据库名称 $db_user：登录数据库名称 $db_pass：登录数据库密码 1 <?php 2 $dsn="mysql:dbname=phpsql;host=localhost;charset=utf8"; 3 $db_user='root'; 4 $db_pass='123456'; 5 try{ 6 $pdo=new PDO($dsn,$db_user,$db_pass); 7 $pdo->exec('set names utf8'); 8 }catch(PDOException $e){ 9 echo '数据库连接失败'.$e->getMessage(); 10 } 11 ?> 三、显示数据列表(list.php) 1 <?php 2 require_once 'db.php'; 3 $sql = 'select * from students'; 4 $query = $pdo->query($sql); 5 echo "<table border='1'>"; 6 echo "<tr><td>id</td><td>number</td><td>name</td><td>操作</td><td>删除</td><

Installing PDO-drivers for PostgreSQL on Mac (using Zend for eclipse)

由 余生长醉 提交于 2020-02-10 02:09:04
问题 How can I get PDO to work on my mac (os x 10.5)? I'm using the built in php and php in Zend/Eclipse. Can't seem to find useful drivers for it at all. 回答1: I had to install the PDO_PGSQL driver recently on Leopard, and I ran across a multitude of problems. In my search for answers, I stumbled across this question. Now I have it successfully installed, and so, even though this question is quite old, I hope that what I've found can help others (like myself) who will undoubtedly run into similar

问题 I looked over PHPDelusions website few times before asking this, as well as used Google but I still can't seem to get the code to work, or find a solution that remotely mirrors my question in general. I made a super simple PHP7 script for managing Receipts. The fields are simple. id (int 12), amount (varchar 8), category (int 2), date (date) The problem I'm facing is I'm trying to Count the Total Amount of money based on Categories . So let's say Category = 1 would count all Amounts with that
