sql server - How to get count and value using one t-sql statement? -

-

here trying get:-

select    column1,    count(column1),    count(column2) table1

i know query invalid. there way can values of column1 , count of column1 , count of column2.

the on clause modifies aggregate range allow query happen want

select    column1,    count(column1) on (),    count(column2) on () table1

edit:

above sql server 2005+

edit 2:

the cross join/count solution in sql server 2000 not reliable under load.

try multiple connections, note @@rowcount never equals t2.cnt in connection 2

--connection 1  set nocount on; drop table dbo.test_table; go create table dbo.test_table (     id_field uniqueidentifier not null default(newid()),     filler char(2000) not null default('a') ); go create unique clustered index idx_id_fld on dbo.test_table(id_field); go while 1 = 1 insert dbo.test_table default values;  --connection 2  select t2.cnt, t1.id_field, t1.filler dbo.test_table t1 cross join (select count(*) cnt dbo.test_table) t2 select @@rowcount  select t2.cnt, t1.id_field, t1.filler dbo.test_table t1 cross join (select count(*) cnt dbo.test_table) t2 select @@rowcount  select t2.cnt, t1.id_field, t1.filler dbo.test_table t1 cross join (select count(*) cnt dbo.test_table) t2 select @@rowcount

edit3: cyberkiwi stated test wrong. rubbish.

if forget @@rowcount, can see cnt different row count in ssms "grid mode"

now, use set transaction isolation level serializable , give correct results, if busy enough inconsistent results want run this?

use temp table ensure consistent dataset if running sql server 2000.
