PHP pdo查询执行错误答案

【问题标题】：PHP pdo query execution errorPHP pdo查询执行错误
【发布时间】：2012-12-29 14:15:08
【问题描述】：

我使用 php 和 pdo 和 pdo_dblib 来执行长选择查询（在这种情况下）。如果我直接在 sql 中运行此查询，我会收到结果，但如果我从 php 运行它，我会收到

207 General SQL Server error: Check messages from the SQL Server [207] (severity 16) [(null)]

我使用debugDumpParams 来查看准备后的查询是什么，但它只转储查询中的前 500 个字符，这可能就是问题所在。这是一些配置参数还是一个错误？

操作系统：Slackware PHP：5.4.7 pdo_dblib - 我自己编译 freetds - 来自http://slackbuilds.org/

Is there a maxium to the output of PDO::debugDumpParams?

代码：

<?php
$dsn = 'dblib:host=XXXXXXXX;dbname=XXXXX';
$username='XXXXX';
$password='XXXXXXX';


$query = "select * from (
                select Row_Number() over (order by 
                order_status.id desc) as RowIndex,  
                order_status.id as ID,
                order_status.caller_type_id as CALLER_TYPE_ID,

                order_status.caller_contact_phone_id as CALLER_CONTACT_PHONE_ID,
                order_status.record_date as DATE,
                order_status.call_date as CALL_DATE,
                order_status.call_time as jueCALL_TIME,
                order_status.username as USERNAME,

                from order_status order_status
                inner join client_data client_data on client_data.id = order_status.caller_client_data_id

                inner join contact_phone on contact_phone.id = order_status.caller_contact_phone_id
             where 1=1 ) as Sub Where Sub.RowIndex >= ? and Sub.RowIndex < ?";


$db = new PDO($dsn, $username, $password);
$prepare = $db->prepare($query, array(PDO::ATTR_CURSOR => PDO::CURSOR_FWDONLY));
$bind = array(1, 11);
if (!$prepare->execute($bind)) {
    $prepare->debugDumpParams();
} else {
    echo "success";
}

输出：

                order_status.call_date as CALL_DATE,

【问题讨论】：

你是用var_dump输出debugDumpParams吗？
你能给我们看看代码吗？
在哪里使用 var_dump？ debugDumpParams 直接输出...
根据 Google 的说法，当 SQL Server 尝试使用不存在的列名时会出现 207 错误。
如果我在 tsql 中运行这个查询，我会收到结果，所以问题不在于不存在的列。

【解决方案1】：

在服务器上为 PDO 进程设置 TDSDUMP 环境变量。该日志将捕获您需要的缺失消息和详细信息。

【讨论】：

在 freetds.conf 中，我从 dump file = /tmp/freetds.log debug flags = 0x80 中删除 cmets，现在在尝试执行 php 脚本时收到 Segmentation fault。

【解决方案2】：

对于耽误您的时间，我深表歉意。我发现我的错误 - 在 MSSQL 中连接到 2 个不同的数据库。

附：如果我在 freetds 配置中启用转储文件，Segmentation fault 仍然会出现错误，但我仍然不知道如何设置 debugDumpParams 以输出超过 500 个字符 Is there a maxium to the output of PDO::debugDumpParams?
