delete एक समय में केवल एक तालिका को संभाल सकता है, इसलिए आपको तीन कथनों की आवश्यकता होगी:
DELETE FROM upklist
WHERE session_id = (SELECT session_id
FROM usession
WHERE delete_session_id IS NULL
AND user_id = (SELECT user_id
FROM users
WHERE REGEXP_LIKE(USER_NAME,
'awpeople', 'i')));
DELETE FROM projshar
WHERE session_id = (SELECT session_id
FROM usession
WHERE delete_session_id IS NULL
AND user_id = (SELECT user_id
FROM users
WHERE REGEXP_LIKE(USER_NAME,
'awpeople', 'i')));
DELETE FROM usession
WHERE session_id = (SELECT session_id
FROM usession
WHERE delete_session_id IS NULL
AND user_id = (SELECT user_id
FROM users
WHERE REGEXP_LIKE(USER_NAME,
'awpeople', 'i')));
ध्यान दें कि चूंकि आंतरिक क्वेरी usersession . पर निर्भर करती है , आपको इसे अंतिम से हटा देना चाहिए ।
