MS SQL Enterprise Manager allows descriptions to be stored with each coumn in table.  What is the SQL syntax to produce the same output as sp_columns but with the description included.

YOu have to use the function fn_listextendedproperty to get the properties.

There is an example in booksonline:

SELECT   *
FROM   ::fn_listextendedproperty (NULL, 'user', 'dbo', 'table', 'T1', 'column', default)


These are the parms:

fn_listextendedproperty (
    { default | [ @name = ] 'property_name' | NULL }
    , { default | [ @level0type = ] 'level0_object_type' | NULL }
    , { default | [ @level0name = ] 'level0_object_name' | NULL }
    , { default | [ @level1type = ] 'level1_object_type' | NULL }
    , { default | [ @level1name = ] 'level1_object_name' | NULL }
    , { default | [ @level2type = ] 'level2_object_type' | NULL }
    , { default | [ @level2name = ] 'level2_object_name' | NULL }
    )

something like this:

select c.COLUMN_NAME,
a.value ColumnDescription,
c.TABLE_CATALOG DatabaseName,
[TABLE_NAME], [COLUMN_DEFAULT], [IS_NULLABLE], [DATA_TYPE], [CHARACTER_MAXIMUM_LENGTH], [CHARACTER_OCTET_LENGTH], [NUMERIC_PRECISION], [NUMERIC_PRECISION_RADIX], [NUMERIC_SCALE], [DATETIME_PRECISION], [CHARACTER_SET_CATALOG], [CHARACTER_SET_SCHEMA], [CHARACTER_SET_NAME], [COLLATION_CATALOG], [COLLATION_SCHEMA], [COLLATION_NAME]

from sysproperties a
inner join
sysobjects b
on
a.id=b.id
inner join
syscolumns d
on b.id=d.id
inner join
INFORMATION_Schema.columns c

on d.name=c.COLUMN_NAME
where a.name='MS_Description' and b.name='YourTableName'

If you want to join it with all the stuff from sp_columns, I think you'll need to use a temp table to hold that info and then join to it, for example:


DECLARE @table SYSNAME
SET @table = N'sections'


IF OBJECT_ID('tempdb.dbo.#sp_columns') IS NOT NULL
      DROP TABLE #sp_columns
CREATE TABLE #sp_columns (
      TABLE_QUALIFIER sysname,
      TABLE_OWNER sysname,
      TABLE_NAME sysname,
      COLUMN_NAME sysname,
      DATA_TYPE smallint,
      TYPE_NAME varchar(13),
      [PRECISION] int,
      LENGTH int,
      SCALE smallint,
      RADIX smallint,
      NULLABLE smallint,
      REMARKS varchar(254),
      COLUMN_DEF nvarchar(4000),
      SQL_DATA_TYPE smallint,
      SQL_DATETIME_SUB smallint,
      CHAR_OCTET_LENGTH int,
      ORDINAL_POSITION int,
      IS_NULLABLE varchar(254),
      SS_DATA_TYPE tinyint
)

SET NOCOUNT ON
INSERT INTO #sp_columns
EXEC sp_columns @table
SET NOCOUNT OFF

SELECT spc.*, ext.value
FROM ::fn_listextendedproperty (NULL, 'user', 'dbo', 'table', 'T1', 'column', 'description') ext
RIGHT OUTER JOIN #sp_columns spc ON spc.column_name = ext.objname

try this one - just remove what you do not need in select:

select *
FROM (sysobjects INNER JOIN syscolumns
ON syscolumns.id = sysobjects.id) LEFT JOIN sysproperties
ON sysproperties.smallid = syscolumns.colid AND
sysproperties.id = syscolumns.id
left join
INFORMATION_Schema.columns c

on sysproperties.name=c.COLUMN_NAME
where sysproperties.name='MS_Description' --and b.name='table1'
and sysobjects.name = 'table1'
