sys.syscacheobjects (Transact-SQL)
Applies to: 
SQL Server
Contains information about how the cache is used.
Important
This SQL Server 2000 system table is included as a view for backward compatibility. We recommend that you use the current SQL Server system views instead. To find the equivalent system view or views, see Mapping System Tables to System Views (Transact-SQL). This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
| Column name | Data type | Description |
|---|---|---|
| bucketid | int | Bucket ID. Value indicates a range from 0 through (directory size - 1). Directory size is the size of the hash table. |
| cacheobjtype | nvarchar(17) | Type of object in the cache: Compiled plan Executable plan Parse tree Cursor Extended stored procedure |
| objtype | nvarchar(8) | Type of object: Stored procedure Prepared statement Ad hoc query (Transact-SQL submitted as language events from the sqlcmd or osql utilities, instead of remote procedure calls) ReplProc (replication procedure) Trigger View Default User table System table Check Rule |
| objid | int | One of the main keys used for looking up an object in the cache. This is the object ID stored in sysobjects for database objects (procedures, views, triggers, and so on). For cache objects such as ad hoc or prepared SQL, objid is an internally generated value. |
| dbid | smallint | Database ID in which the cache object was compiled. |
| dbidexec | smallint | Database ID from which the query is executed. For most objects, dbidexec has the same value as dbid. For system views, dbidexec is the database ID from which the query is executed. For ad hoc queries, dbidexec is 0. This means dbidexec has the same value as dbid. |
| uid | smallint | Indicates the creator of the plan for ad hoc query plans and prepared plans. -2 = The batch submitted does not depend on implicit name resolution and can be shared among different users. This is the preferred method. Any other value represents the user ID of the user submitting the query in the database. Overflows or returns NULL if the number of users and roles exceeds 32,767. |
| refcounts | int | Number of other cache objects referencing this cache object. A count of 1 is the base. |
| usecounts | int | Number of times this cache object has been used since inception. |
| pagesused | int | Number of pages consumed by the cache object. |
| setopts | int | SET option settings that affect a compiled plan. These settings are part of the cache key. Changes to values in this column indicate users have modified SET options. These options include the following: ANSI_PADDING FORCEPLAN CONCAT_NULL_YIELDS_NULL ANSI_WARNINGS ANSI_NULLS QUOTED_IDENTIFIER ANSI_NULL_DFLT_ON ANSI_NULL_DFLT_OFF |
| langid | smallint | Language ID. ID of the language of the connection that created the cache object. |
| dateformat | smallint | Date format of the connection that created the cache object. |
| status | int | Indicates whether the cache object is a cursor plan. Currently, only the least significant bit is used. |
| lasttime | bigint | For backward compatibility only. Always returns 0. |
| maxexectime | bigint | For backward compatibility only. Always returns 0. |
| avgexectime | bigint | For backward compatibility only. Always returns 0. |
| lastreads | bigint | For backward compatibility only. Always returns 0. |
| lastwrites | bigint | For backward compatibility only. Always returns 0. |
| sqlbytes | int | Length in bytes of the procedure definition or batch submitted. |
| sql | nvarchar(3900) | Module definition or the first 3900 characters of the batch submitted. |
