Question

我已经为此搜索过高低，我无法绕过它。我有一个表单来搜索Permit Applications。输入您的许可证号码，它针对3个单独的SQL Server视图运行3个查询。查询在同一个if语句中几乎完全相同，但最后一个查询失败。我已经执行了var_dump($query_insp_history)复制输出并直接在SSMS中运行新查询，它运行正常。是否有其他错误检查可以提供除sqlsrv_fetch_array() expects parameter 1 to be resource, boolean given以外的更多详细信息？我相信我的参数设置正确，如果结构不同，请告诉我。

// Application Inspection History Section是给我问题的部分。我只是无法弄清楚出现它的设置与其他两个查询的设置方式相同。我在这行代码while($row = sqlsrv_fetch_array($sql_insp_history, SQLSRV_FETCH_ASSOC)){

收到错误

var_dump($sql_insp_history);
返回
bool(false)

var_dump($query_insp_history);
返回
string(81) "SELECT * FROM my.dbo.vw_Permit_App_Insp_History WHERE (LTRIM(APNO) = '123456')"再次，将其复制到SSMS中正确运行...

提前谢谢。

这是我的代码。

Answer 1

如果

According to its documentation, sqlsrv_query()在成功时收到错误或声明资源，则返回false。

你必须养成检查SQL操作中的错误的习惯，否则你永远不会知道你停在哪附近，弗罗斯特先生。

你想要这样的东西：

$sql_permit_info = sqlsrv_query($conn, $query_permit_info);  
if ($sql_permit_info === false) {
    die( print_r( sqlsrv_errors(), true));
} 
while ($row= sqlsrv_fetch_array($sql_permit_info, SQLSRV_FETCH_ASSOC)) {

Answer 2

我正在使用的视图中的某些内容必须不正确。我将原始SELECT语句从视图中删除并插入到我的$sql_permint_info中，现在一切正常。

sqlsrv_fetch_array（）期望参数1是资源，给定布尔值
