Oracle/PL-SQl：将查询结果传递给另一个更新

Question

Hi I am trying to update using PL/SQL based on one query result store the result and send this result to Update query but getting

ORA-06550: line 2, column 24: PLS-00103: Encountered the symbol "end-of-file" when expecting one of the following: := ( ; not null range default character

Table:

    create table person(id number(10),stat char(1));
    insert into person(id,stat)values(123,'Y');
    insert into person(id,stat)values(123,'Y');
    insert into person(id,stat)values(345,'Y');
    commit;

Query:

DECLARE
  deptid  person.id%TYPE;
BEGIN
  SELECT id INTO deptid 
     FROM person WHERE id = 345;
  IF SQL%FOUND THEN 
    Update person set stat='N' where id=deptid;
    commit;
    DBMS_OUTPUT.PUT_LINE('Dept Id: ' || deptid ||);
  END IF;
END;
/

What am i doing wrong here?

Answer 1

Use a RETURNING clause in the UPDATE :

DECLARE
  deptid  person.id%TYPE;
BEGIN
  UPDATE person
  SET    stat = 'N'
  WHERE  id = 123
  RETURNING MAX(id) INTO deptid;
  
  DBMS_OUTPUT.PUT_LINE('Dept Id: ' || deptid);
END;
/

Which, for your test data:

create table person(id,stat) AS
SELECT 123, 'Y' FROM DUAL UNION ALL
SELECT 123, 'Y' FROM DUAL UNION ALL
SELECT 345, 'Y' FROM DUAL;

Then the PL/SQL block outputs:

Dept Id: 123

And the table contains the values:

\n ID | STAT\n--: |  :--- \n123 |  N    \n123 |  N    \n345 |Y   \n

If you really want to use a SELECT statement then you need to make sure it only returns a single row:

DECLARE
  deptid  person.id%TYPE;
BEGIN
  SELECT id
  INTO   deptid
  FROM   person
  WHERE  id = 123
  AND    ROWNUM = 1; -- FETCH FIRST ROW ONLY; 

  UPDATE person
  SET    stat = 'N'
  WHERE  id = deptid;
  
  DBMS_OUTPUT.PUT_LINE('Dept Id: ' || deptid);
EXCEPTION
  WHEN NO_DATA_FOUND THEN
    DBMS_OUTPUT.PUT_LINE( 'No Dept Id!' );
END;

Answer 2

Query that you posted as example has an error which cause code to fail. Please remove extra pipes after deptid and before ')' in dbms_output command.

DBMS_OUTPUT.PUT_LINE('Dept Id: ' || deptid);
