i have entity model of oracle data source on have no control. using model query particular view see volume price breaks given product: as can see, view has no primary key. here linq using: var db = getoracledatacontext(); var result = db.itempricebreaks_v.where(p => p.stockno == stockid).tolist(); this works degree, instead of returning 4 distinct records own quantities , pricing, returns 4 identical records, each pricing , quantities of first record ($4800, 0, 2). i have no control on view. there way can structure linq query can 4 distinct values? select fields care , use distinct(). example: var result = db.itempricebreaks_v .where(p => p.stockno == stockid) .select(p => p.price) .distinct() .tolist(); however, i'd recommend, along other commenters, primary key involved.

c - Create sysfs entry from kernel module -

-
i want pass string > 1024 chars module (filesystem). kernel parameters limited 1024 chars, someone recommended use sysfs instead. i tried include this example in super.c class create string 'filename' & string 'code' entry in sysfs module. static decl_subsys(myfs, null, null); struct myfs_attr { struct attribute attr; char *value; }; static struct myfs_attr fname = { .attr.name="filename", .attr.owner = this_module, .attr.mode = 0644, .value = "/my/test/path", }; static struct myfs_attr code = { .attr.name="code", .attr.owner = this_module, .attr.mode = 0644, .value = "0101", }; when compiling module lot of errors (line 41 decl_subsys): fs/myfs/super.c:41:26: error: expected ‘)’ before ‘(’ token fs/myfs/super.c:50:2: error: unknown field ‘owner’ specified in initializer fs/myfs/super.c:50:2: warning: initialization incompatible pointer type [enabled default] fs/myfs/s

javascript - forEach on a 'new Array' isn't doing what I expect -

i'm learning how use js higher-order functions (map, foreach, reduce, etc), , have stumbled confusion. i'm trying write simple 'range' function, can't seem populate output array. goal: range(1, 4) // [1, 2, 3, 4] i'm getting this: [undefined × 4] here code: function range(num1, num2) { var rangearr = new array((num2 + 1) - num1); return rangearr.map(function(e, i, arr) {return arr[i] = num1 + i}); } what missing here? far can tell problem appears have way i'm utilizing 'new array', beyond i'm lost. oh, , here's part confuses me. works fine: function bleck() { var blah = [1, 2, 3, 4]; var x = 'wtf'; return blah.map(function(e, i, arr) {return arr[i] = x}) } ["wtf", "wtf", "wtf", "wtf"] thanks!! the foreach method iterates on the indices of array . interestingly enough, when create new array via new array(n) , contains no indices @
