select语句的循环结果引发错误

Question

    <?php
include 'config.php';
$query = sqlsrv_query($conn1, "SELECT * FROM dnmembership.[dbo].DNAuth a JOIN dnworld.[dbo] Characters b ON a.CharacterID = b.CharacterID where a.CertifyingStep = 2");

while($row = sqlsrv_fetch_array($query,SQLSRV_FETCH_ASSOC)){
echo $row['CharacterName']. '<br/>';
}
?>

此代码遇到以下错误代码：警告：sqlsrv_fetch_array（）期望参数1为资源，第5行的C：\\ xampp \\ htdocs \\ usersonline.php中给出的布尔值

有人知道为什么吗？

Answer 1

您缺少[dbo]和Characters之间的句点（ . ）：

SELECT * 
FROM   dnmembership.[dbo].DNAuth a 
JOIN   dnworld.[dbo].Characters b ON a.CharacterID = b.CharacterID 
------------- Here -^
WHERE  a.CertifyingStep = 2
