SQL Server 2000 Useful Undocumented Stored Procedures

,

Introduction

In this article, I want to tell you about some useful undocumented

stored procedures shipped with SQL Server 2000.

sp_MSget_qualified_name

This stored procedure is used to get the qualified name for the given

object id.

Syntax

sp_MSget_qualified_name object_id, qualified_name

where

object_id
is the object id. object_id is int.
qualified_name
is the qualified name of the object. qualified_name is nvarchar(512).

This is the example to get the qualified name for the authors table

from the pubs database.

USE pubs

GO

declare @object_id int, @qualified_name nvarchar(512)

select @object_id = object_id('authors')

EXEC sp_MSget_qualified_name @object_id, @qualified_name output

select @qualified_name

GO

Here is the result set from my machine:

--------------------------------------

[dbo].[authors]

sp_MSdrop_object

This stored procedure is used to drop the object (it can be table,

view, stored procedure or trigger) for the given object id, object

name, and object owner. If object id, object name, and object owner

are not specified, then nothing will be dropped.

Syntax

sp_MSdrop_object [object_id] [,object_name] [,object_owner]

where

object_id
is the object id. object_id is int,

with a default of NULL.

object_name
is the name of the object. object_name is sysname,

with a default of NULL.

object_owner
is the object owner. object_owner is sysname,

with a default of NULL.

This is the example to drop the titleauthor table from the

pubs database.

USE pubs

GO

declare @object_id int

select @object_id = object_id('titleauthor')

EXEC sp_MSdrop_object @object_id

GO

sp_gettypestring

This stored procedure returns the type string for the given table id

and column id.

Syntax

sp_gettypestring tabid, colid, typestring

where

tabid
is the table id. tabid is int.
colid
is the column id. colid is int.
typestring
is the type string. It's output parameter.

typestring is nvarchar(255).

This is the example to get the type string for the column number 2

in the authors table, from the pubs database.

USE pubs

GO

declare @tabid int, @typestring nvarchar(255)

select @tabid = object_id('authors')

EXEC sp_gettypestring @tabid, 2, @typestring output

select @typestring

GO

Here is the result set from my machine:

-------------------------------

varchar(40)

sp_MSgettools_path

This stored procedure returns the path to the SQL Server 2000 tools

and utilities.

Syntax

sp_MSgettools_path install_path

where

install_path
is the installation path. It's output parameter.

install_path is nvarchar(260).

This is the example to get the path to the SQL Server 2000 tools

and utilities.

USE master

GO

declare @install_path NVARCHAR(260)

EXEC sp_MSgettools_path @install_path OUTPUT

select @install_path

GO

Here is the result set from my machine:

------------------------------------------------------------

C:\Program Files\Microsoft SQL Server\80\Tools

sp_MScheck_uid_owns_anything

This stored procedure returns the list of the object, owned by the

specified user.

Syntax

sp_MScheck_uid_owns_anything uid

where

uid
is the User ID, unique in this database. 1 is the database owner.

uid is smallint.

This is the example to get the list of the objects, owned by the

database owner in the pubs database.

USE pubs

GO

EXEC sp_MScheck_uid_owns_anything 1

GO

sp_columns_rowset

This stored procedure returns the complete columns description,

including the length, type, name, and so on.

Syntax

sp_columns_rowset table_name [, table_schema ] [, column_name]

where

table_name
is the table name. table_name is sysname.
table_schema
is the table schema. table_schema is sysname,

with a default of NULL.

column_name
is the column name. column_name is sysname,

with a default of NULL.

This is the example:

USE pubs

GO

EXEC sp_columns_rowset 'authors'

GO

sp_fixindex

This stored procedure can be used to fix a corruption in a system table

by recreate the index.

Syntax

sp_fixindex dbname, tabname, indid

where

dbname
is the database name. dbname is sysname.
tabname
is the system table name. tabname is sysname.
indid
is the index id value. indid is int

Note. Before using this stored procedure the database has to be

in single user mode.

See this link for more information:

"How can I fix a corruption in a system table?"

http://www.windows2000faq.com/Articles/Index.cfm?ArticleID=14051

This is the example:

USE pubs

GO

EXEC sp_fixindex pubs, sysindexes, 2

GO

sp_MSforeachdb

Sometimes, you need to perform the same actions for all databases.

You can make cursor for this purpose, but you can also use

sp_MSforeachdb stored procedure in this case.

You can use this stored procedure to check all databases with

DBCC CHECKDB statement:

EXEC sp_MSforeachdb @command1="print '?' DBCC CHECKDB ('?')"

sp_MSforeachtable

Sometimes, you need to perform the same actions for all tables in the

database. You can make cursor for this purpose, but you can also use

sp_MSforeachtable stored procedure in this case.

You can use this stored procedure to rebuild all indexes in your

database. Try to schedule it to execute when your server is not

very hard work.

EXEC sp_MSforeachtable @command1="print '?' DBCC DBREINDEX ('?')"

sp_MShelpcolumns

This stored procedure returns the complete schema for a table, including

the length, type, name, and whether a column is computed.

Syntax

sp_MShelpcolumns tablename [, flags] [, orderby] [, flags2]

where

tablename
is the table name. tablename is nvarchar(517).
flags
flags is int, with a default of 0.
orderby
orderby is nvarchar(10), with a default of NULL.
flags
flags2 is int, with a default of 0.

To get the full columns description for the authors table in the

pubs database, run:

USE pubs

GO

EXEC sp_MShelpcolumns 'authors'

GO

sp_MShelpindex

This stored procedure returns information about name, status, fill

factor, index columns names, and about used file group for the given

table.

Syntax

sp_MShelpindex tablename [, indexname] [, flags]

where

tablename
is the table name. tablename is nvarchar(517).
indexname
is the index name. indexname is nvarchar(258),

with a default of NULL.

flags
flags is int, with a default of NULL.

To get the indexes description for the authors table in the

pubs database, run:

USE pubs

GO

EXEC sp_MShelpindex 'authors'

GO

sp_MShelptype

This stored procedure returns many useful information about system

data types and about user data types.

Syntax

sp_MShelptype [typename] [, flags]

where

typename
is the type name. typename is nvarchar(517),

with a default of NULL.

flags
flags is nvarchar(10), with a default of NULL.

To get information about all built-in and user defined data types

in the pubs database, run:

USE pubs

GO

EXEC sp_MShelptype

GO

sp_MSindexspace

This stored procedure returns the size in kb, which the indexes in

the particular table use.

Syntax

sp_MSindexspace tablename [, index_name]

where

tablename
is the table name. tablename is nvarchar(517).
index_name
is the index name. index_name is nvarchar(258),

with a default of NULL.

To determine the space used by the indexes from the authors table

in the pubs database, run:

USE pubs

GO

EXEC sp_MSindexspace 'authors'

GO

sp_MSkilldb

This stored procedure sets database to suspect and let dbcc dbrepair

to kill it. You should run this sp from the context of the master

database. Use it very carefully.

Syntax

sp_MSkilldb dbname

where

dbname
is the database name. dbname is nvarchar(258).

To kill the pubs database, run:

USE master

GO

EXEC sp_MSkilldb 'pubs'

the table and index use.

Syntax

sp_MStablespace name [, id]

where

name
is the table name. name is nvarchar(517).
id
id is int, with a default of NULL.

To determine the space used by the authors table in the pubs database,

run:

GO

EXEC sp_MStablespace 'authors'

GO

Here is the result set from my machine:

Rows        DataSpaceUsed IndexSpaceUsed

----------- ------------- --------------

23 8 32

sp_tempdbspace

This stored procedure can be used to get the total size and the space

used by the tempdb database. You should execute sp_tempdbspace without

parameters.

Syntax

sp_tempdbspace

This is the example:

EXEC sp_tempdbspace

Here is the result set from my machine:

database_name database_size           spaceused

------------- ----------------------- -----------------------------

tempdb 9.750000 .562500

sp_who2

This stored procedure returns information about current SQL Server 2000

users and processes as sp_who, but provides more detailed information.

sp_who2 returns CPUTime, DiskIO, LastBatch and ProgramName in addition

to sp_who.

Syntax

sp_who [loginame]

where

loginame
the user's login name. If not specified, the procedure

reports on all active users of SQL Server.

This example returns information for the 'sa' login:
