使用 php 和 sql server 处理 null 和 bit 字段

【问题标题】：working with null and bit fields with php and sql server使用 php 和 sql server 处理 null 和 bit 字段
【发布时间】：2013-06-20 05:03:44
【问题描述】：

我将使用 this 的值：

$HEA_LivingWill  = $_POST['HEA_LivingWill'] == 'on'  ? true : false;

更新 sql server 表中的 bit 字段。

请注意上面的代码是php。

我想$_POST['HEA_LivingWill'] 的值可以是'on'、null，或者任何与“on”相反的值

从 php 中的常规变量处理 bit sql server 字段的正确方法是什么？

请注意，当我执行update mytable set my field =$HEA_LivingWill 之类的 sql 语句时，查询甚至不会通过。它没有给我一条错误消息，而且我知道查询没有执行，因为我使用 sql server profiler/

请注意，我也尝试让$HEA_LivingWill = $_POST['HEA_LivingWill'] == 'on' ? 1:0; 收到相同的结果。

如果你感兴趣，下面是从 php 运行的插入语句：

 $create_info = mssql_query("INSERT INTO

 ,'$HEA_MOST'

我确定我遗漏了一些细节，请让我知道我还能提供什么。

请注意$_POST[] variables 是从上一页抓取的。这里是entire first page 这些变量的来源。

如果您想查看执行INSERT, here it is.的页面的完整源代码

我确实放了：

or var_dump($create_info);

而不是or die(...);

虽然没有出错，但也没有执行任何操作

我也试过放置

,1,1,1,1,1            
 )") or die ("Error - No record creation");

代替：

 ,$HEA_LivingWill          
 ,$HEA_Medical_Power_Attorney
 ,$HEA_POLST 
 ,$HEA_MOST                  
 ,$HEA_DNR  )") or die ("Error - No record creation");

结果没有变化。记录不受影响

【问题讨论】：

  • $HEA_LivingWill = $_POST['HEA_LivingWill'] = 'on' ? true : false; 你不应该使用== 'on'吗？
  • 这是一个很好的观点，但是仍然得到相同的结果
  • 您的“更新语句”实际上是一个插入语句。再说一遍，您是要更新还是插入？
  • 道歉我的意思是插入
  • 请为Health 发布您的数据库结构。我还计算了 63 个列名，它们匹配。

【解决方案1】：

请尝试插入：

$create_info = mssql_query("INSERT INTO 
Health 
(RES_ID, HEA_LastUser, HEA_DateStamp, HEA_Vision, HEA_Hearing, HEA_Mobility, HEA_Falls, HEA_Food, HEA_FoodPref, HEA_FoodDetails, HEA_Insect, HEA_InsectDetails, HEA_Driver, HEA_Make, HEA_Model, HEA_Year, HEA_Color, HEA_Plate, HEA_ParkArea, HEA_Care, HEA_Height, HEA_Weight, HEA_History1, HEA_History2, HEA_History3, HEA_History4, HEA_History5, HEA_History6, HEA_History7, HEA_History8, HEA_History9, HEA_History10, HEA_History11, HEA_History12, HEA_History13, HEA_History14, HEA_History15, HEA_History16, HEA_OtherIll, HEA_HistoryDetails, HEA_HospName, HEA_HospPhone, HEA_PhyName1, HEA_PhyAddress1, HEA_PhyPhone1, HEA_PhyFax1, HEA_PhyEmail1, HEA_PhySpecialty1, HEA_PhyName2, HEA_PhyAddress2, HEA_PhyPhone2, HEA_PhyFax2, HEA_PhyEmail2, HEA_PhySpecialty2, HEA_OtherAll, HEA_OtherDetails, HEA_Pendant, HEA_Storage

,HEA_LivingWill            
,HEA_Medical_Power_Attorney
,HEA_POLST                 
,HEA_MOST                  
,HEA_DNR     )              

VALUES 
($RES_ID, $USR_ID, '$HEA_DateStamp',$HEA_Vision, $HEA_Hearing, $HEA_Mobility, $HEA_Falls, '$HEA_Food', $HEA_FoodPref, '$HEA_FoodDetails', '$HEA_Insect', '$HEA_InsectDetails', '$HEA_Driver', '$HEA_Make', '$HEA_Model', '$HEA_Year', '$HEA_Color', '$HEA_Plate', '$HEA_ParkArea', $HEA_Care, '$HEA_Height', '$HEA_Weight', '$HEA_History1', '$HEA_History2', '$HEA_History3', '$HEA_History4', '$HEA_History5', '$HEA_History6', '$HEA_History7', '$HEA_History8', '$HEA_History9', '$HEA_History10', '$HEA_History11', '$HEA_History12', '$HEA_History13', '$HEA_History14', '$HEA_History15', '$HEA_History16', '$HEA_OtherIll', '$HEA_HistoryDetails', '$HEA_HospName', '$HEA_HospPhone', '$HEA_PhyName1', '$HEA_PhyAddress1', '$HEA_PhyPhone1', '$HEA_PhyFax1', '$HEA_PhyEmail1', '$HEA_PhySpecialty1', '$HEA_PhyName2', '$HEA_PhyAddress2', '$HEA_PhyPhone2', '$HEA_PhyFax2', '$HEA_PhyEmail2', '$HEA_PhySpecialty2', '$HEA_OtherAll', '$HEA_OtherDetails', '$HEA_Pendant', '$HEA_Storage' 

,$HEA_LivingWill          
,$HEA_Medical_Power_Attorney
,$HEA_POLST                 
,$HEA_MOST                  
,$HEA_DNR                
)") or die ("Error - No record creation");

如果还是不行，请在查询后发var_dump($create_info)。

【讨论】：

  • @Артём Царионов，你试过这个吗？
  • 非常感谢，你改了什么？我现在就试试
  • 对于这个声明我得到了错误 - 没有创建记录
  • 至少这应该证明您的原始查询虽然没有按预期执行...如果您运行原始查询并执行var_dump($create_info)，其中有什么？
  • 我做了这样的查询............ ,$HEA_MOST ,$HEA_DNR )") 或 var_dump($create_info); （你可以在最后看到我放 var_dump 而不是“或死”，转储没有显示任何内容，应该这样吗？
【解决方案2】： 
$HEA_LivingWill  = ($_POST['HEA_LivingWill'] =='on')  ? 1 : 0;

您需要将 False/True 值转换为 0/1。 SQL Server 不会为您执行此隐式转换。

【讨论】：

  • 删除插入语句中'$HEA_LivingWill'周围的单冒号
  • 根据帖子，他试过$HEA_LivingWill = $_POST['HEA_LivingWill'] = 'on' ? 1:0; 不一样。
  • pastebin.com/TvXKCaBX 此代码显示了首先填充的变量
  • 我还贴出了整个站点有插入查询的源代码
  • @DynamicDeveloper 那么你怎么看？还有其他建议吗？
