आप इसे स्थानान्तरण के साथ प्राप्त नहीं कर सकते। इसके बजाय natural full outer join
. का उपयोग करने का प्रयास करें
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');
आपको मिलता है
PERSON SENIOR MID JUNIOR
