Question

我用ROW和PAGE方法压缩了我的表。在压缩类型向导中，它显示正确的状态。但是，当我尝试从sys.partitions读取状态时，会将某些表保留为NONE。令人困惑的是，状态在2个视图中是不同的。

我已经尝试过多次将其更改为“无”，然后再次尝试将其压缩，但是没有运气。

SELECT DISTINCT
    s.name AS schma,
    t.name,
    p.rows,
    p.data_compression_desc,
    'ALTER TABLE [' +s.name+ '].['+t.name+'] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = ROW)' 

FROM sys.tables t
LEFT JOIN sys.indexes i
ON t.object_id = i.object_id
JOIN sys.schemas s
ON t.schema_id = s.schema_id
LEFT JOIN sys.partitions p
ON i.index_id = p.index_id
    AND t.object_id = p.object_id
WHERE t.type = 'U' 
  AND p.data_compression_desc = 'NONE'
ORDER BY p.rows DESC```

How could I ensure about the method of compression.

压缩类型显示ROW，而在sys.partitions中则显示NONE
