当连接oracle用pdo 执行insert时会报以下错误 ：
:(
SQLSTATE[IM001]: Driver does not support this function: driver does not support lastInsertId()
错误位置
FILE: /www/test/ThinkPHP/Library/Think/Db/Driver/Oracle.class.php 　LINE: 87
TRACE
#0 /www/test/ThinkPHP/Library/Think/Db/Driver/Oracle.class.php(87): PDO->lastInsertId()

oracle是不支持lastinsertid()的

以下是网上找到的解决方案：        $this->bind = $this->bind ? $this->bind : $bind;  //新增
        foreach ($this->bind as $key => $val) {
            if(is_array($val)){
                $this->PDOStatement->bindValue($key, $val[0], $val[1]);
            }else{
                $this->PDOStatement->bindValue($key, $val);
            }
        }
        $this->bind =   array();        
        $result    =    $this->PDOStatement->execute();
        $this->debug(false);
        if ( false === $result) {
            $this->error();
            return false;
        } else {
            $this->numRows = $this->PDOStatement->rowCount();
            if($flag || preg_match("/^\s*(INSERT\s+INTO|REPLACE\s+INTO)\s+/i", $str)) {
                // $this->lastInsID = $this->_linkID->lastInsertId();
                $this->lastInsID = $this->lastInsertId($this->table); //修改
            }
            return $this->numRows;
        }
