PHP致命错误：未捕获com_异常-插入VFP9数据库

PHP致命错误：未捕获com_异常：源：ADODB.Connection
说明：参数类型错误、超出可接受范围或相互冲突。在C:\inetpub\wwwroot\sonreceive\api\create\u test.php:66中 堆栈跟踪：

C:\inetpub\wwwroot\sonreceive\api\create\u test.php（66）：com->prepare（'INSERT-INTO-SON…'））

C:\inetpub\wwwroot\sonreceive\api\create\u test.php（35）：create（）

{main} 在第66行的C:\inetpub\wwwroot\sonreceive\api\create\u test.php中抛出

这是php文件create_test.php中的错误消息：

根据这条消息，我认为问题在于INSERT查询，但没有任何线索，因为INSERT语句似乎没有问题

我在这个论坛和其他网站上看过类似的“未捕获的com_例外”帖子，但它们并不完全属于这种类型。有人遇到过类似的情况吗

错误实际上是由以下原因引起的：

在字符字段的INSERT语句的VALUES子句中，不将php变量括在引号中

数字字段的情况正好相反

请注意，提供给INSERT语句的值来自解码的JSON字符串。请参阅下面的工作代码

您是否确认所提供的值实际上是其各自字段的正确类型。VFP对此非常严格。您是否尝试过减少语句并只传递部分字段以找出导致错误的原因？谢谢您的建议。是的，值的类型是正确的，但是在减少语句并用空字符串填充值时，我发现INSERT语句无法识别PHP变量（$variablename）。因此出现了uncaught com_execption:syntax error。仍然需要找到一种方法让INSERT语句接受VALUES子句中的PHP变量。
