sql - Getting the value of no grouping column -

-
i know basics in sql programming , know how apply tricks in sql server in order result set, don't know tricks in oracle. i have these columns: col1 col2 col3 and wrote query select col1, max(col3) mx3 mytable group col1 and need value of col2 in same row found max value of col3, know trick solve problem? a couple of different ways this: in both cases i'm treating initial query either common table expression or inline view , joining base table added column. trick here inner join eliminates records not in max query. select a.*, mytable inner join (select col1 , max( col3 ) mx3 mytable group col1) b on a.col1=b.col1 , b.mx3 = a.col3 or with cte (select col1 , max( col3 ) mx3 mytable group col1) select a.* mytable inner join cte on a.col1 = b.col1 , a.col3= cte.mx3

-
i'm trying update database maintained , deployed using database project ( .sqlproj ) in visual studio 2012. easier sql server management studio, in case have deploy using dacpac. what correct way change column not nullable, using dacpac , without risking data loss? a nullable column added table. need publish update sets column not null , sets default. because there rows in table, update fails. there setting 'allow data loss' isn't option , update should not result in data loss. here's simple example shows problem: create table [dbo].[hello] ( [id] int identity(100,1) not null primary key, [hellostring] nvarchar(50) null , [language] nchar(2) not null ) now publish database , add rows, @ least 1 row should have null hellostring. change table definition be: create table [dbo].[hello] ( [id] int identity(100,1) not null primary key, [hellostring] nvarchar(50) not null default 'hello' , [language] nchar(2) not null )

ecmascript 6 - Is it possible to destructure an object and generate a new object in a single statement? -

-
this question has answer here: create subset object, consisting of of properties of existing object [duplicate] 1 answer const {name, slug, description, parent} = cat; const sanecat = {name, slug, description, parent}; in first expression, define 4 constants destructuring messy object. in second expression, combine them new object. in single step without duplicating list of interesting fields, because first expression doesn't define object, seems impossible. really? close clojurian win! i have tried following without success. ecmascript compiler fair game, don't have option of using clojurescript. const sanecat = {name, slug, description, parent} = cat; // name not defined const {...sanecat} = {name, slug, description} = cat; // name not defined const sanecat = ({name, slug, description, parent} = cat); // name not defined const sanecat = ({name, slug,
