[Solved] SQL Rows into Columns

You cannot achieve this with transpose. rather try using natural full outer join

WITH T
    AS (SELECT
             P.*,
             ROW_NUMBER ( )
                 OVER (PARTITION BY PERSON, LEVELS ORDER BY LANGUAGE)
                 R
        FROM
             PROGRAMMER P)
SELECT
      PERSON,
      SENIOR,
      MID,
      JUNIOR
FROM
      (SELECT
            PERSON,
            R,
            LANGUAGE SENIOR
       FROM
            T
       WHERE
            LEVELS = 'SENIOR')
      NATURAL FULL OUTER JOIN (SELECT
                                PERSON,
                                R,
                                LANGUAGE MID
                          FROM
                                T
                          WHERE
                                LEVELS = 'MID')
      NATURAL FULL OUTER JOIN (SELECT
                                PERSON,
                                R,
                                LANGUAGE JUNIOR
                          FROM
                                T
                          WHERE
                                LEVELS = 'JUNIOR');

You get

PERSON          SENIOR               MID                  JUNIOR
