i have been trying connect rabbitmq when broker in shutdown state. far have:

    com.rabbitmq.client.connectionfactory factory = new      com.rabbitmq.client.connectionfactory();     factory.sethost("localhost");     factory.setport(5672);     factory.setautomaticrecoveryenabled(true);     factory.setnetworkrecoveryinterval(100000);      factory.setconnectiontimeout(100000);     factory.sethandshaketimeout(100000);      return factory.newconnection();

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

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() .
