求教mongo字段是索引数组怎么查询啊
SupplierIDS为1的所有数据用的thinkphp
mongodb中使用aggregate可以返回数组字段数组的指定索引的元素参考语句：{$match:{'duid':15}},{$project:{duid:1,"default":1}},{$unwind:"$default.styles"},{$match:{'default.styles.status':1}},{$group:{_id:"$_id","defaults":{$push:"$default.styles"}}}解释：1：过滤数据{$match:{'duid':15}}2：获取想要的列{$project:{duid:1,"default":1}}3：获取后数组字段{$unwind:"$default.styles"}4：条件查询数组元素{$match:{'default.styles.status':1}}5：分组后保存结果{$group:{_id:"$_id","defaults":{$push:"$default.styles"}}}数据结构如下：{"_id":ObjectId("55dad346ea23e7c11beefce5"),"duid":11.0,"default":{"style":"普通会诊","alias":"","money":"0","styles":[{"code":1,"style":"普通会诊","alias":"一般会诊","money":100,"status":1,"remark":"需要患者亲自来到医院"}{"code":6,"style":"夜间门诊","alias":"夜间门诊","money":100,"status":0,"remark":"夜间门诊"},{"code":7,"style":"其他门诊","alias":"其他门诊","money":10,"status":0,"remark":"其他门诊"}]}}
