Merging keys in concourse YAML files -


how can merge keys in concourse? var file has key value pairs like

cf-api-app: api- cf-dispatcher-app: dispatcher- cf-space: test

in pipeline want pass param task should like

pcf_api_app_name: ((cf-api-app))-((cf-space)) pcf_dispatcher_app_name: ((cf-dispatcher-app))-((cf-space))

so task can param based on environment, , like

pcf_api_app_name: api-test pcf_dispatcher_app_name: dispatcher-test

but guess somehow, not take combination expected , unable evaluate it.

i tried using anchor in config.yml can merge keys in config file instead of pipeline still not work. 

aliases: &environ test  cf-api-app: api-*environ (fails) cf-dispatcher-app: dispatcher-*environ (fails) cf-space: *environ (works)

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() .
