Question

$マッチ集約式の内部で許可されていません$

」$マッチ集約式Iが実行

の内部で許可されていないところ$次のクエリ

var query = { $and : [ 
    {"order.orderstatus" : "F"}, 
    {"partsupp.supplier.nation.name" : { $regex : '^SAUDI ARABIA'} }, 
    {$where : "this.receiptdate > this.commitdate"} 
]}; 

var multisupp = { 
    $where : function() { 
     return db.lineitems.findOne({ $and : [ 
      { "order.orderkey" : this.order.orderkey }, 
      { "partsupp.supplier.suppkey" : { "$ne" : this.partsupp.supplier.suppkey} } 
     ]}) != null; 
    } 
}; 

var onlyfail = { 
    $where : function() { 
     return db.lineitems.findOne({ $and : [ 
      { "order.orderkey" : this.order.orderkey }, 
      { "partsupp.supplier.suppkey" : { "$ne" : this.partsupp.supplier.suppkey} }, 
      { $where : "this.receiptdate > this.commitdate" } 
      ]}) == null; 
    } 
}; 

res = db.lineitems.aggregate([ 
    { $match : query}, 
    { $match : multisupp}, 
    { $match : onlyfail}, 
    { $project : { 
     _id : 0, 
     s_name : "$partsupp.supplier.name" } }, 
    { $group : { 
     _id : "$s_name", 
     numwait : { $sum : 1} } }, 
    { $sort : { numwait : -1, _id : 1} } 
]); 

そしてこれはコレクションスキーマです。 （このコレクションは、巨大なスキーマを持っていますが、私はその問題のために重要ではないと思います）

誰かがそれを解決するために私を助けることができますか？ありがとうございました。

Answer 1

エラーが示すように、集約クエリ内に$whereを含めることはできません。

var query = { $and : [ 
    {"order.orderstatus" : "F"}, 
    {"partsupp.supplier.nation.name" : { $regex : '^SAUDI ARABIA'} }, 
    {receiptdate : { $gt : commitdate} 
]};
