对于grails应用程序,我需要找到一个对象列表,其中"attr"是动态字符串列表中的一个.实际的HQL查询更复杂,但我需要帮助的是这个:
def result = MyObject.executeQuery("select o from MyObject as o where o.attr in :list",
[list: aListOfStrings])

这显然不是正确的语法,Grails将它作为"意外令牌"抛回给我,作为:list参数.
这在HQL中是否可行?我并不特别想在代码库的这一部分使用Criteria.
What is the best way to wait for multiple asynchronous callback functions to finish in Java before continuing. Specifically I'm using GWT with AsyncCallback, but I think this is a generic problem. Here's what I have now, but surely there is cleaner way...
AjaxLoader.loadApi("books", "0", new Runnable(){
public void run() {

I also read that it is possible to do it using the 4.0 framework, but have yet to find any supporting evidence.
So my question, is it possible to perform SOUNDEX via a LINQ to SQL Query?

My RegEx replaces spaces with hyphens. But when a user types "Hi there" (multiple spaces) the slug ends up as "Hi-----there". When really it should be "Hi-there".
Should I create the regular expression so that it only replaces a space when there is a character either side?
Or is there an easier way to do this?
