SELECT 'ALTER table '||OWNER|| '.'||table_NAME|| ' enable row movement ;'
FROM DBA_tables
WHERE OWNER= '&USER'

WHERE OWNER= '&USER'
union all
SELECT 'ALTER table '||OWNER|| '.'||table_NAME|| ' disable row movement ;'
FROM DBA_tables
WHERE OWNER= '&USER'
UNION ALL
SELECT 'ALTER INDEX '||OWNER|| '.'||INDEX_NAME|| ' shrink space ;'
FROM DBA_INDEXES
WHERE TABLE_OWNER= '&USER'
FROM DBA_tables
WHERE OWNER= '&USER'
union all
SELECT 'ALTER table '||OWNER|| '.'||table_NAME|| ' shrink space ;'
