Degree of Parallelism (7.0 Insert) Event Class

The Degree of Parallelism (7.0 Insert) event class occurs each time SQL Server executes a SELECT, INSERT, UPDATE, or DELETE statement.

When this event class is included in a trace, the amount of entailed overhead may significantly impede performance if these events occur frequently. To minimize overhead incurred, limit use of this event class to traces that briefly monitor specific problems.

Degree of Parallelism (7.0 Insert) 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

BinaryData

image

Number of CPUs used to complete the process based on the following values:

  • 0x00000000, indicates a serial plan running in serial.
  • 0x01000000, indicates a parallel plan running in serial.
  • >= 0x02000000 indicates a parallel plan running in parallel.

2

No

ID assigned by the host computer to the process where the client application is running. This data column is populated if the client process ID is provided by the client.

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

Event Class

int

Type of Event = 28.

27

No

EventSequence

int

Sequence of a given event within the request.

51

No

EventSubClass

int

Indicates the statement executed, based on the following values:

1=Select

2=Insert

3=Update

4=Delete

21

No
