为什么我的 SQL Server 查询失败? [英] Why is my SQL Server query failing?

问题描述

 connect();
 $arr = mssql_fetch_assoc(mssql_query("SELECT Applications.ProductName,
        Applications.ProductVersion, Applications.ProductSize, 
        Applications.Description, Applications.ProductKey, Applications.ProductKeyID,
        Applications.AutomatedInstaller, Applications.AutomatedInstallerName,
        Applications.ISO, Applications.ISOName, Applications.Internet,
        Applications.InternetURL, Applications.DatePublished, Applications.LicenseID,
        Applications.InstallationGuide, Vendors.VendorName
FROM Applications
INNER JOIN Vendors ON Applications.VendorID = Vendors.VendorID
WHERE ApplicationID = ".$ApplicationID));

$query1 = mssql_query("SELECT Issues.AppID, Issues.KnownIssues
      FROM Issues 
      WHERE Issues.AppID=".$ApplicationID);   
$issues = mssql_fetch_assoc($query1);
$query2 = mssql_query("SELECT ApplicationInfo.AppID,
               ApplicationInfo.Support_Status, ApplicationInfo.UD_Training,
               ApplicationInfo.AtomicTraining, ApplicationInfo.VendorURL
   FROM  ApplicationInfo
   WHERE ApplicationInfo.AppID = ".$ApplicationID);
$row = mssql_fetch_assoc($query2);
function connect(){
 $connect =  mssql_connect(DBSERVER, DBO, DBPW) or 
        die("Unable to connect to server");
 $selected = mssql_select_db(DBNAME, $connect) or 
        die("Unable to connect to database");
 return $connect;
}

上面是代码.第一个 query/fetch_assoc 工作得很好，但是接下来的 2 个查询失败了，我不知道为什么.这是从 php 显示的错误语句:

Above is the code. The first query/fetch_assoc works perfectly fine, however the next 2 queries fail and I cannot figure out why. Here is the error statement that shows up from php:

该错误显然集中在查询未执行这一事实上.在我的数据库中，我有一个名为 Issues 的表和一个名为 ApplicationInfo 的表，所以我不确定为什么它告诉我它们是无效对象.

The error clearly centers around the fact that the query is not executing. In my database I have a table called Issues and a table called ApplicationInfo so I am unsure why it is telling me that they are invalid objects.

推荐答案

检查您查询的数据库或架构是否正确.

Check that you're querying the right database or schema.

software.software_dbo.ApplicationInfo 表示:

• 名为software的数据库
• 一个名为 software_dbo 的架构 - 可能是这个问题.可能是 SQL Server 上的 dbo.
• 一个名为 ApplicationInfo
的视图/表

• a database named software
• a schema named software_dbo - likely this is the problem. Likely is dbo on your SQL Server.
• a view/table named ApplicationInfo

也许检查一下 DBO 的值，以及其他参数，在这个语句中:$connect = mssql_connect(DBSERVER, DBO, DBPW)

Perhaps check what the value of DBO, amongst the other arguments, is in this statement: $connect = mssql_connect(DBSERVER, DBO, DBPW)
