ADF - Access #table or Temp table used in Script task activity output to be used in Copy activity as source

Question

We have simple script consider the one below as an example.

Script:

create table #tableABC (
    col A varchar(10),
    col B varchar(10),
    col C varchar(10)
)

insert into #tableABC
    select 'A' ,'B', 'C'

The above script is considered as an SP and excepted in script task and it works. but we are unable to access the #table in the following copy activity

select * from #tableABC;

Answer 1

Azure data factory doesn't support automatic temporary table creation and we cannot set table name with ## as starting.

1. TempDB is the location where we can find the temporary tables. We cannot choose the temporary tables as datasets in ADF
