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.
