Question

I have a simple SQL Statement that works perfectly in SQL Server:

DECLARE @ID VARCHAR(10)
SET @ID = '12345'

SELECT *
FROM theTable 
WHERE ID = @ID

Can someone please tell me how to do this extremely basic thing in Oracle?

Answer 1

If your goal is to set the variables at the top of the script maybe this is your solution?

with IDS as (
    select 1234 from dual
    union all
    select 1235 from dual
)

select * from TABLE where TABLE.ID in (select * from IDS)
