This column is populated with the values passed by the application rather than the displayed name of the program.|10|Yes| |**ClientProcessID**|**int**|ID assigned by the host computer to the process where the client application is running. This data column is populated if the client provides the client process ID.|9|Yes| |**ColumnPermissions**|**int**|Indicates whether a column permission was set. Parse the statement text to determine which permissions were applied. 1=Yes, 0=No.|44|Yes| |**DatabaseID**|**int**|ID of the database specified by the USE *database* statement or the default database if no USE *database* statement has been issued for a given instance. [!INCLUDE[ssSqlProfiler](../../includes/sssqlprofiler-md.md)] displays the name of the database if the **ServerName** data column is captured in the trace and the server is available. Determine the value for a database by using the DB_ID function.|3|Yes| |**DatabaseName**|**nvarchar**|Name of the database in which the user statement is running.|35|Yes| |**DBUserName**|**nvarchar**|Issuer's username in the database.|40|Yes| |**EventClass**|**int**|Type of event = 114.|27|No| |**EventSequence**|**int**|Sequence of a given event within the request.|51|No| |**HostName**|**nvarchar**|Name of the computer on which the client is running. This data column is populated if the client provides the host name. To determine the host name, use the HOST_NAME function.|8|Yes| |**IsSystem**|**int**|Indicates whether the event occurred on a system process or a user process. 1 = system, 0 = user.|60|Yes| |**LoginName**|**nvarchar**|Name of the login of the user (either the [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] security login or the [!INCLUDE[msCoName](../../includes/msconame-md.md)] Windows login credentials in the form of DOMAIN\username).|11|Yes| |**LoginSid**|**image**|Security identification number (SID) of the logged-in user. You can find this information in the **sys.server_principals** catalog view. Each SID is unique for each login in the server.|41|Yes| |**NTDomainName**|**nvarchar**|Windows domain to which the user belongs.|7|Yes| |**NTUserName**|**nvarchar**|Windows user name.|6|Yes| |**ObjectName**|**nvarchar**|Name of the object whose permissions are being checked.|34|Yes| |**ObjectType**|**int**|Value representing the type of the object involved in the event. This value corresponds to the type column in the **sys.objects** catalog view. For values, see [ObjectType Trace Event Column](../../relational-databases/event-classes/objecttype-trace-event-column.md).|28|Yes| |**OwnerName**|**nvarchar**|Database username of the object owner of the object being targeted.|37|Yes| |**ParentName**|**nvarchar**|Name of the schema that the object is within.|59|Yes| |**Permissions**|**bigint**|Integer value representing the type of permissions checked.

For example, if you connect to [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] using Login1 and execute a statement as Login2, **SessionLoginName** shows Login1 and **LoginName** shows Login2. This column displays both [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] and Windows logins.|64|Yes| |**SPID**|**int**|ID of the session on which the event occurred.|12|Yes| |**StartTime**|**datetime**|Time at which the event started, if available.|14|Yes| |**Success**|**int**|1 = success. 0 = failure.
