Function Trace Profiler Results - Database Structure

Applies to AQTime 8.81, last modified on January 18, 2022

The Function Trace profiler results are stored in a number of tables within the specified database. The contents of most of these tables correspond to the contents of AQTime panels in which the profiling results are stored. This topic describes the structure of the database that stores the exported Function Trace profiler results.

The database consists of the following tables:

The relationship between the mentioned tables are illustrated in the image below. This relationship is similar to the relationship of the data in AQTime’s Explorer, Report and Details panels that hold the Function Trace profiler results.

The top-level table of the database is INSTANCES. It stores the list of exported result sets. Each exported result set has a unique identifier contained in the INST_ID field. All other tables of the database also have INST_ID fields. The values stored in these fields indicate which result set a specific table item belongs.

The profiling results in the Explorer panel are organized into two categories, Call Trace and Routines. The Function Trace profiling information displayed in AQTime’s Report panel for these categories, is stored in the FUNCTION_TRACE_PROFILER_CALL_TRACE and FUNCTION_TRACE_PROFILER_META_ROUTINES tables, respectively. The profiling results displayed in AQTime’s Details panel for each category depends on which item of the Report panel is selected. That is why the tables storing the information displayed in the Details panel have a special PARENT_ID field that specifies the Report panel item to which a specific record relates.

Note: The ID and REC_ID columns of the FUNCTION_TRACE_PROFILER_xxxx tables are not key columns. They may contain repetitive values. In queries you should use these values along with the INST_ID value (the result set identifier).

Below is detailed information about the tables.
