Data Compression

Syntax:-
=================

USE [student]
GO
Select
'ALTER TABLE ['+B.Name+'].['+ A.Name+ '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE)'
from sys.objects A INNER JOIN
sys.schemas B on A.Schema_id=B.Schema_id
where type = 'U' and A.name not like 'dtproperties'

ALTER TABLE [dbo].[Category] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE)

For All Tables :-
===============
EXEC sp_MSforeachtable @command1 = 'alter table ? REBUILD WITH (DATA_COMPRESSION = PAGE);'


To Verify:-
========

SELECT
SCHEMA_NAME(sys.objects.schema_id) AS [SchemaName]
,OBJECT_NAME(sys.objects.object_id) AS [ObjectName]
,[rows]
,[data_compression_desc]
,[index_id] as [IndexID_on_Table]
FROM sys.partitions
INNER JOIN sys.objects
ON sys.partitions.object_id = sys.objects.object_id
WHERE data_compression > 0
AND SCHEMA_NAME(sys.objects.schema_id) <> 'SYS'
ORDER BY SchemaName, ObjectName
