Working with Database Calls view - ANTS Performance Profiler

In ANTS Performance Profiler 7.3 Professional, the Database Calls view shows performance data for all the database calls your application made during the time period you have selected.

If a call was made multiple times, it is still shown only once in Database Calls view, with timing and hit count data aggregated from each instance of the call.

Note that database call performance data is not recorded when profiling in sampling mode.

app_dbcall_view

The following data is shown for each database call, for the time period you have selected:

Query: The first line of the database query (excluding any initial blank lines). To view the full query text, move the mouse over the row.
Time to first result (ms): The time taken (in milliseconds) until the query returned its first result.

Where a call was made multiple times, Time to first result shows the sum of the time to return a first result taken by all instances of the call.

Hit count: The number of times the call was made.

When a query is selected, a green highlight on the timeline shows the period when the call was running. Source code for the selected query is shown below the list of queries, in SQL Source View.

Linking back to your code

To find out which of your code's methods ran a particular SQL query:

In Database Calls view, select the query.
A icon appears on the right-hand side of the Query column.
Click on the icon.
The display switches to Performance view, displaying the call tree, with the SQL query selected.

You can scroll up the call tree to locate the query's .NET parent, and browse its timings to determine whether the problem lies in the way the query is called.

For more information on understanding .NET method timings, see Working with the call tree.
