postgresql - Converting a returned SETOF into An Array in PL/PgSQL (specifically) -


i know there process of select array_agg(f) (select blah stuff) f, great in sql, when writing functions in pl/pgsql, there shorthand method??

i'm trying put json keys array can use @ length. like...

v_len := array_length( array_agg(json_object_keys(myjson)), 1);

instead of long, declare variable, select array_agg(f) ..., i've been doing. i've seem hundreds of implementations using same sql string, want cut down code, fingers going numb redundant typing.

what missing shorthand method?

you can use array(subselect) constructor

do $$ declare int[]; begin   := array(select * generate_series(1,10));   raise notice 'result: %', a; end; $$;

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() .
