SQL Log File Schema

Important

PDH support for ODBC SQL databases may be altered or unavailable in the future.

Applications can use PDH APIs read and write performance counter data in compatible ODBC SQL databases and then perform further processing through SQL queries. This section describes the SQL schema used to store performance counters. You can use this information to create custom views and reports. The schema consists of the following three tables:

• CounterData
• CounterDetails
• DisplayToID

Note

PDH support for ODBC SQL databases only works with ODBC SQL drivers that support Bulk Copy (BCP) Extensions.
