Example

Table

DatabaseID:ObjectID:IndexID

TAB: 5:261575970:1
 In this case, database ID 5 is the pubs sample database and object ID 261575970 is the titles table and 1 is the clustered index.

Page

DatabaseID:FileID:PageID

PAGE: 5:1:104
 In this case, database ID 5 is pubs, file ID 1 is the primary data file, and page 104 is a page belonging to the titles table.
To identify the object id that the page belongs to, use the DBCC PAGE (dbid, fileid, pageid, output_option) command, and look at the m_objId. For example:
DBCC TRACEON ( 3604 )
DBCC PAGE ( 5 , 1 , 104 , 3 )

Key

DatabaseID:Hobt_id (Hash value for index key)

KEY: 5:72057594044284928 (3300a4f361aa)

In this case, database ID 5 is Pubs, Hobt_ID 72057594044284928 corresponds to non clustered index_id 2 for object id 261575970 (titles table). Use the sys.partitions catalog view to associate the hobt_id to a particular index id and object id. There is no way
to unhash the index key hash to a specific index key value.

Row

DatabaseID:FileID:PageID:Slot(row)

RID: 5:1:104:3

In this case, database ID 5 is pubs , file ID 1 is the primary data file, page 104 is a page belonging to the titles table, and slot 3 indicates the row's position on the page.

Compile

DatabaseID:ObjectID [[COMPILE]]

TAB: 5:834102012 [[COMPILE]] This is not a table lock, but rather a compile lock on a stored procedure. Database ID 5 is pubs, object ID 834102012 is stored procedure usp_myprocedure. See Knowledge Base Article 263889
for more information on blocking caused by compile locks.
