How to concatenate varchar into a string in Redshift table
我有一个table如下:
create table #t1(a1 varchar(2))
insert into #t1 select 'AA'
insert into #t1 select 'BB'
我想要最终结果如下:我应该使用哪个聚合函数。
'AA,BB'
来自LISTAGG Function - Amazon Redshift:
select listagg(sellerid, ', ') within group (order by sellerid) from sales
where eventid = 4337;
listagg
----------------------------------------------------
380, 380, 1178, 1178, 1178, 2731, 8117, 12905, 32043
