Answer 1

If any of you still not able to DROP the table. Try this. You can able to see all the details by running this

SELECT
    TABLE_NAME,
    COLUMN_NAME,
    CONSTRAINT_NAME,
    REFERENCED_TABLE_NAME,
    REFERENCED_COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE REFERENCED_TABLE_NAME = 'ReferenceTableName'; <-- change only this

If you want to see just the constrains

SELECT
    CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE REFERENCED_TABLE_NAME = 'ReferenceTableName';
