SELECT wm_concat(COLUMN_NAME) from (
SELECT OWNER
,TABLE_NAME
,COLUMN_ID
,COLUMN_NAME
,DATA_TYPE
,DATA_LENGTH
FROM DBA_TAB_COLUMNS
WHERE OWNER='BUAABHXG'
AND TABLE_NAME='UUFS_XSXX_XJB' ) A WHERE A.COLUMN_NAME IN (SELECT COLUMN_NAME
FROM DBA_TAB_COLUMNS
WHERE OWNER='UUFNEWXG'
AND TABLE_NAME='UUFS_XSXX_XJB')
