Preparing “Data Dictionary” using SQL Query

Data dictionary is the required while documenting any project. So here is the query for preparing the data dictionary of any database.

SELECT [Table Name] = OBJECT_NAME(c.object_id)
,[Column Name] = c.name
,[Data Type] = t.name
,[Size] = c.max_length
,[Description] = isnull(ex.value,'') 
FROM sys.columns c 
LEFT OUTER JOIN sys.extended_properties ex ON (ex.major_id = c.object_id AND ex.minor_id = c.column_id AND ex.name = 'MS_Description') 
INNER JOIN sys.types t ON c.system_type_id = t.system_type_id 
WHERE OBJECTPROPERTY(c.object_id, 'IsMsShipped')=0 
AND OBJECT_NAME(c.object_id) in (select name from sys.tables where type= 'U') 
ORDER BY OBJECT_NAME(c.object_id), c.column_id

Just include the column of the table definition (if any other required - i.e. if you want to display whether the column is null/not null, just include the field from sys.objects table and so on).
