我正在尝试在一页上显示 3 个表格。

我使用了 3 个不同的查询,但第二个查询时出现错误。我假设这不是语法错误,但也可能是。如果您需要更多详细信息,请告诉我。

代码,

<?php
session_start();
if ($_SESSION['loggedin'] != "YES")
{
header("location:index.php?problem=notLoggedIn");
}
$name = $_SESSION['username'];
?>
<html>
<div style="width: 80%; margin-left:auto; margin-right:auto;">
<div style="float: right;">Welcome <? print($name); ?></div>
<?php
//Connect to MSSQL Server
$myServer = ".\MSSQLSERVER2008";
$myUser = "admin";
$myPass = "password";
$myDB = "database";

//connection to the server
$dbhandle = mssql_connect($myServer, $myUser, $myPass)
or die("Couldn't connect to SQL Server on $myServer");

//select a database to work with
$selected = mssql_select_db($myDB, $dbhandle)
or die("Couldn't open database $myDB");

$result = mssql_query("SELECT *
FROM table1
INNER JOIN table4
ON table1.user_id=table4.user_id;");
if(!$result){
//echo 'Failed to receive data. Please try again, or contact support.';
}
else{
//echo 'Successfully received data.';
//$results = mssql_query($result);
//var_dump($results);
}
?>

<style>
select {
-webkit-appearance: none;
-moz-appearance: none;
text-indent: 1px;
text-overflow: '';

select::-ms-expand {
display: none;
}

td a:link {
color: white;
}

td a:visited {
color: white;
}

td a:active {
color: white;

</style>

</html>

错误如下:

Parse error: syntax error, unexpected T_VARIABLE

对于此行:

$result2 = mssql_query("SELECT *

最佳答案

$result2 查询中的 JOIN 子句包含“ON tale2.user_id=table4.user_id; ”。我假设你的意思是 table2.user_id 而不是 tale2.user_id ?事实上,这不仅仅是一个假设,因为您是从 table2 而不是 tale2 中进行选择。 (我会将此作为评论包含在内,但还没有声誉级别。)
