SQL 2008 : Apply Compression to all Tables and Indexes

Apply Compression to all Tables and Indexes
(example uses Page Compression)

SELECT 'ALTER TABLE [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE);' FROM sys.objects where TYPE = 'u'
UNION
SELECT 'ALTER INDEX ALL ON [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE);' FROM sys.objects where TYPE = 'u'

Table Compression : List compressed / uncompressed objects

Table compression - List compressed objects (tables & indexes)

SELECT
SCHEMA_NAME(sys.objects.schema_id) AS [SchemaName]
,OBJECT_NAME(sys.objects.object_id) AS [ObjectName]
,[rows]
,[data_compression_desc]
,[index_id]
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

Table compression - List uncompressed objects (tables & indexes)
(Note the subtle difference in WHERE clause)

SELECT
SCHEMA_NAME(sys.objects.schema_id) AS [SchemaName]
,OBJECT_NAME(sys.objects.object_id) AS [ObjectName]
,[rows]
,[data_compression_desc]
,[index_id]
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

Table Compression Cheat

Creating a table with compression...

CREATE TABLE dbo.testtable (testcolumn1 char(1000), testcolumn2 int) WITH (DATA_COMPRESSION = PAGE);

Changing a table to take advantage of compression functionality...

ALTER TABLE dbo.testtable REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE); 

Want to implement table compression on all tables in a sql 2008 db?
Here's dynamic sql to build those commands...

page compression...

SELECT 'ALTER TABLE [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = PAGE);' FROM sys.objects where TYPE = 'u'

row compression...

SELECT 'ALTER TABLE [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = ROW);' FROM sys.objects where TYPE = 'u'

and to remove it again...

SELECT 'ALTER TABLE [' + SCHEMA_NAME(schema_id) + '].[' + NAME + '] REBUILD PARTITION = ALL WITH (DATA_COMPRESSION = NONE);' FROM sys.objects where TYPE = 'u'
