OLEDB Provider Information Event Class

The OLEDB Provider Information event class occurs when a distributed query is run and collects information corresponding to the provider connection.

This event class contains all the properties that are collected from the remote provider by using various property sets, including the following:

  • DBPROPSET_DATASOURCEINFO

  • SQLPROPSET_OPTHINTS

  • DBPROPSET_SQLSERVERDATASOURCEINFO ( SQL Server only)

  • DBPROPSET_SQLSERVERDBINIT ( SQL Server only)

  • DBPROPSET_ROWSET

  • IDBInfo interface

    These properties, along with available metadata, are used by the query optimizer to choose the optimal execution plan for the query. This information is useful for tracing execution and analyzing OLE DB calls and events in distributed query profiler traces.

OLEDB Provider Information 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
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
EventClass int Type of event = 194. 27 No
EventSequence int Sequence of a given event within the request. 51 No
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
IsSystem int Indicates whether the event occurred on a system process or a user process. 1 = system, 0 = user. 60 Yes
LinkedServerName nvarchar Name of the linked server. 45 Yes
LoginName nvarchar Name of the login of the user (either SQL Server security login or the Windows login credentials in the form of DOMAIN\username). 11 Yes

NTUserName nvarchar Windows user name. 6 Yes
ProviderName nvarchar Name of the OLE DB provider. 46 Yes
RequestID int ID of the request containing the statement. 49 Yes
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
