更新我的Gridview搜索框以使用LIKE而不是＆＃39; =或null＆＃39;

Question

我目前有一个gridview，顶部有文本框，用户可以留空（在这种情况下会返回表中的所有记录），或者用户可以提供与表中相应字段中信息的完全匹配。将结果限制为仅限于那些记录的文本框具有在相应字段中具有文本框内容的那些行。我有14个这样的文本框，它们的任意组合都可以填充或保留未使用状态，为用户需要的记录创建一个过滤器。

但我想把它带到下一步。而不是要求完全匹配＆＃39;我宁愿做一个喜欢。基本上，如果我提供单词dog，我希望select有效地作为％dog％运行。我尝试了几种不同的方法来解决这个问题，但我似乎无法做任何事情。所以我想我会把我的代码放在这里，然后屏幕截图显示我所拥有的内容，看看是否有人建议如何实现这一目标。

我的aspx页面看起来像这样：

希望有人有一些见解，因为我希望能够对这些文本框实现LIKE。

Answer 1

在where子句中需要IS NULL OR LIKE。

SelectCommand="SELECT AssetID, ..., AssetOperStatus 
FROM cmdbv_Assets_CInTrac 
WHERE (@AssetID IS NULL OR AssetID LIKE '%' + @AssetID + '%') AND 
...
(@AssetStatus IS NULL OR AssetStatus LIKE '%' + @AssetStatus + '%')"

来自胜利： （RTRIM（LTRIM（ISNULL（@AssetID，''）））=''或AssetID LIKE'％'+ @AssetID +'％'）
