Equivalent of DUAL table in OTBI

Question

Hello,

Is there a way to select from DUAL table in OTBI?

Like if I have a query on a subject area that gets me values and I want to add a fixed value to the results by doing a union with Dual table, or equivalent in OTBI.

Thank you

No but you can add a union to select a constant from a subject area that you know will only return 1 row.

(select all 0 as s_0, "presentation table"."presentation column" as s from "subject area" ) 
union all 
(select all 0 as s_0, 'xx' as s from "subject area" )

for example i added the 1999 row "from dual"

SELECT 
  saw_0,
  saw_1,
  saw_2
 FROM ((SELECT 
  cast("Time"."Year" as character) saw_0,
  "Query Execution"."Success Flag" saw_1,
  "Facts - Usage Metrics"."Report Count" saw_2
 FROM "OTBI Usage Real Time"
) UNION (SELECT 
  '1999' saw_0,
  'U' saw_1,
  99 saw_2
 FROM "OTBI Usage Real Time"
)) t1 ORDER BY saw_0, saw_1
