    Cool. The Word template is what I've been looking for. I built an aspx app to display table columns in a grid, but could not figure out how to get our doc pages in SharePoint to embed that output.

    For a particular table, I wanted the column attributes as well as the description info, so used something like this:

    SELECT C.ColumnName, DataType, Length, NullsAllowed, DefaultValue, Description FROM


    DATA_TYPE AS DataType,


    IS_NULLABLE AS NullsAllowed,

    COLUMN_DEFAULT AS DefaultValue

    FROM Information_Schema.Columns

    WHERE Table_Name = @Table) AS C


    (SELECT objname AS ColumnName, value AS Description

    FROM fn_listextendedproperty (Default, 'schema', 'dbo', 'table', @Table, 'column', default)

    WHERE name = 'MS_Description') AS D

    ON C.ColumnName COLLATE Latin1_General_CI_AS = D.ColumnName

    Nice one cjs - shows how much you can do with this - and in so many ways - when you try!

    Great article/ series! Makes me want to start documenting my databases! 😛 (Yea, I'm way behind on that)

    Your first image depicting the sys.extended_properties view looks different from mine. I'm running SS2008R2, and my columns match your article description (ie major_id, minor_id, name, value), but your image has column names of PropertyType, SchemaName, TableName, etc). Was that the wrong image, or did you join the sys.extended_properties view to other system views?

    Hi Patrick,

    Thanks for the feedback, and you are quite right, this is the wrong image. I'll try & correct, but it might be a day or two...

    All the best,

    An excellent set of articles. Does anyone know how to return the extended properties of Database Roles in the same way?

    Apply with:

    EXEC sys.sp_addextendedproperty





    Query with:

    SELECT *

    FROM sys.extended_properties AS xp

    INNER JOIN sys.database_principals AS dp

    ON xp.major_id = dp.principal_id

    AND xp.class_desc = 'DATABASE_PRINCIPAL'
