Access SQL 查询缺少更多必需参数

在一个网络项目中，我尝试执行以下查询：

SELECT ItemName as Name,
       ItemPicture as Picture,
       ItemHeroModif as Assistance,
       ItemTroopModif as Charisma,
       HerbCost as Herbs,
       GemCost as Gems
FROM Item WHERE ItemId = @value0

通过断点，我可以看到我附加到@value0价值，2.

尽管如此，我还是收到以下错误：

没有为一个或多个必需参数给出值。

我知道这个错误通常是由于错误的 SQL 语法而产生的。我的做法有什么问题吗？

EDIT:

附件代码：

var madeForCommand = "SELECT ItemName as Name,ItemPicture as [Picture],ItemHeroModif as Assistance,ItemTroopModif as Charisma, HerbCost as Herbs, GemCost as Gems FROM Item WHERE ";
OleDbCommand command = new OleDbCommand();
for (int ii = 0; ii < items.Count; ii++)// items is a list of items with IDs I want to get from the query.
{
    madeForCommand += "ItemId =@value"+ii+" OR ";   
}
madeForCommand = madeForCommand.Substring(0, madeForCommand.Length - 4); // making sure I trim the final or; In the case I shown, it's just one item, so there are none at all.

后来：

OleDbCommand forOperations = new OleDbCommand(madeForCommand, _dbConnection); //_dbConnection is the connection to the database, it seems to work pretty well.
for (int ii = 0; ii < items.Count; ii++) 
{
    string attach = "@value" + ii;
    command.Parameters.AddWithValue(attach, items[ii].ID);
}

我相当确定items[ii].ID没问题，断点显示它等于 2 并且附件运行良好。

EDIT 2: 我已经按照 Krish 和 Hans 的建议编辑了代码，我得到以下查询，没有任何附件：

SELECT ItemName as [Name],ItemPicture as Picture,ItemHeroModif as Assistance,ItemTroopModif as Charisma, HerbCost as Herbs, GemCost as Gems FROM [Item] WHERE (ItemID in (2));

如果它改变了任何东西，我仍然会遇到同样的错误。

EDIT 3: 在 Access 中执行查询要求我为参数“ItemPicture”提供一个值...奇怪； ItemPicture 是一个列，不是吗？

Name, Item, and Picture are 问题词 http://allenbrowne.com/AppIssueBadWord.html在 Access 查询中。将它们括在方括号中：

SELECT ItemName as [Name], ItemPicture as [Picture], ItemHeroModif as Assistance, ItemTroopModif as Charisma, HerbCost as Herbs, GemCost as Gems
FROM [Item] WHERE ItemID in (2);

由于将这些名称括起来仍然会给您带来缺少参数的投诉，因此我要求您在 Access 的查询设计器中测试该查询。在这种情况下，Access 会显示一个参数输入框，其中还包含 Access 将其解释为参数的单词。

您报告了 Access 认为项目图片是一个参数。因此，通过在 Access 设计视图中检查该表，您发现实际的字段名称是项目图像URL.

SELECT ItemName as [Name], ItemImageURL as [Picture], ItemHeroModif as Assistance, ItemTroopModif as Charisma, HerbCost as Herbs, GemCost as Gems
FROM [Item] WHERE ItemID in (2);
