insert的问题
页面放了一个panel，里面一个edit，一个button，然后在button的onclick事件里加了个函数，如下
function insertdb($sender, $params)
{
$this->Table1->Open();
$this->Table1->Append();
$this->Table1->ID=45;
$this->Table1->MINGCHENG=$this->Edit1->Text;
$this->Table1->SHIFOUZHUCE=2;
$this->Table1->Post();
$this->Table1->Close();
}
运行的时候出现问题，提示无法将null插入到'ID'中（这里我的ID为pk），错误如下：
Callstack #0 File: C:\test\unit4.php Line: 47（这里47行为$Unit4->loadResource(__FILE__);）
|_Callstack #1 File: D:\program files\CodeGear\Delphi for PHP\1.0\vcl\classes.inc.php Line: 1698
|_Callstack #2 File: D:\program files\CodeGear\Delphi for PHP\1.0\vcl\classes.inc.php Line: 1745

根据错误提示查看源码，发现dbtables.inc.php Line: 881之前有段代码，
if (is_array($this->_keyfields))
{
reset($this->_keyfields);
while(list($key, $fname)=each($this->_keyfields))
{
unset($this->fieldbuffer[$fname]);
}
}
}
（此为881行）$insertSQL = $this->Database->_connection->AutoExecute($this->TableName, $this->fieldbuffer, 'INSERT');
在这里将keyfield的值都销毁了，当然插不进去了，搞不懂为什么要加这段代码？往高手解惑
