Question

The code

   SELECT some_identifier_id INTO a_someid_id FROM "SOME_IDENTIFIER" SOME_IDT
  INNER JOIN "CASE" cse ON cse.customer_id = '1001'
  INNER JOIN "MEASURE" m ON m.case_id = cse.case_id
WHERE SOME_IDT.some_identifier_type_code = '430101';

Gives out an “missing keyword” error. Where the problem lies?

Answer 1

You can use INTO only when you execute the query in a PL/SQL program block (either anonymous, trigger, stored proc…).

An SQL query cannot contain an INTO clause, and it will give you this error.

-- Will fail
SELECT 1 INTO x FROM dual;

-- Will succeed
declare x int;
begin
   SELECT 1 INTO x FROM dual;
end;
