尝试执行以下代码时出现错误:

myQuery = queryNew("id,name,amount","Integer,Varchar,Integer", 
            [ 
                    {id=1,name="One",amount=15}, 
                    {id=2,name="Two",amount=18}, 
                    {id=3,name="Three",amount=32},
                    {id=4,name="Four",amount=27},
                    {id=5,name="Five",amount=43},
                    {id=6,name="Six",amount=71}
            ]);

get=myQuery.filter(function(obj){
   return (order by obj.name )
});
writeOutput("The filtered query is:")
writeDump(get);

错误显示“在第 16 行第 22 列找到无效的 CFML 构造”。

我知道上面的错误是因为 obj.name 作为返回参数的 order。但是我怎么能没有任何错误呢?谢谢你。

要做一个order by,你需要做sort()而不做filter()

<cfscript>
myQuery = queryNew("id,name,amount","Integer,Varchar,Integer", 
            [ 
                    {id=1,name="One",amount=15}, 
                    {id=2,name="Two",amount=18}, 
                    {id=3,name="Three",amount=32},
                    {id=4,name="Four",amount=27},
                    {id=5,name="Five",amount=43},
                    {id=6,name="Six",amount=71}
            ]);

myQuery.sort("name", "desc");
writeOutput("The filtered query is:")
writeDump(myQuery);
</cfscript>

编辑:无需引用get,只需引用查询本身。
