Progress Report: Online Index Operation Event Class Data Columns
| Data column name | Data type | Description | Column ID | Filterable |
|---|---|---|---|---|
| ApplicationName | nvarchar | Name of the client application that created the connection to an instance of SQL Server. This column is populated with the values passed by the application rather than the displayed name of the program. | 10 | Yes |
| BigintData1 | bigint | Number of rows inserted. | 52 | Yes |
| BigintData2 | bigint | 0 = serial plan; otherwise, the thread ID during parallel execution. | 53 | 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 |
| 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. SQL Server Profiler 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 |
| Duration | bigint | Amount of time (in microseconds) taken by the event. | 13 | Yes |
| EndTime | datetime | Time at which the online index operation completed. | 15 | Yes |
| EventClass | int | Type of event = 190. | 27 | No |
| EventSequence | int | Sequence of a given event within the request. | 51 | No |
| EventSubClass | int | Type of event subclass. 1=Start 2=Stage 1 execution begin 3=Stage 1 execution end 4=Stage 2 execution begin 5=Stage 2 execution end 6=Inserted row count 7=Done Stage 1 refers to the base object (clustered index or heap), or if the index operation involves one nonclustered index only. Stage 2 is used when an index build operation involves both the original rebuild plus additional nonclustered indexes. For example, if an object has a clustered index and several nonclustered indexes, 'rebuild all' would rebuild all indexes. The base object (the clustered index) is rebuilt in stage 1, and then all the nonclustered indexes are rebuilt in stage 2. |
21 | Yes |
| GroupID | int | ID of the workload group where the SQL Trace event fires. | 66 | Yes |
| 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 |
| IndexID | int | ID for the index on the object affected by the event. | 24 | 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 SQL Server security login or the Microsoft 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 |
| ObjectID | int | System-assigned ID of the object. | 22 | Yes |
| ObjectName | nvarchar | Name of the object being referenced. | 34 | Yes |
| PartitionId | bigint | The ID of the partition being built. | 65 | Yes |
| PartitionNumber | int | The ordinary number of the partition being built. | 25 | Yes |
| ServerName | nvarchar | Name of the instance of SQL Server being traced. | 26 | No |
| SessionLoginName | nvarchar | Login name of the user who originated the session. For example, if you connect to SQL Server using Login1 and execute a statement as Login2, SessionLoginName shows Login1 and LoginName shows Login2. This column displays both SQL Server 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. | 14 | Yes |
| TransactionID | bigint | System-assigned ID of the transaction. | 4 | Yes |
