ios - How to search in firebase database? -


i'd make search bar, , if search word, i'd data include word on firebase.

i've implimented search bar , looking have write in func searchbarsearchbuttonclicked(_ searchbar: uisearchbar).

so far, have idea. uses "for" , "if" run code data.

for in (~) {     let defaultplace = dbref.child("posts/\(i)/age")     defaultplace.observe(.value) { (snap: firdatasnapshot) in          if ~ {             self.displayage.text = (snap.value! anyobject).description         }     } }

(↑ example. "~" something)

but i'm not sure if it's best way.

ios:

queryordered(bychild: "{field name}").querystarting(atvalue: "{value}")

replace {field name} , {value}

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
