View and Add Charts

SQL Inspector > View and Add Charts

When you first select an Inspector in the SQL Inspector window, one chart group showing the CPU time displays in the top pane with the following:

Statistics

Select the statistic to display on the chart from the drop-down field.

No. of Top Consumption SQLs and Percentage of Total Consumption sliders

These two sliders work in conjunction with each other. If you select the number of SQL statements and Transact-SQL using the No. of Top Consumption SQLs slider, the Percentage of Total Consumption slider is adjusted to show the percentage of the SQL statements that correspond to the number of selected SQL.

If you select the Percentage of Total Consumption, the corresponding number of SQL is shown in the No. of Top Consumption SQL's slider.

The SQL statements and Transact-SQL that are shown in the statistics pane are determined by the statistics that is selected for each chart and by the selection of the AND or OR criteria for joining the SQL statements based on the selected statistics.

Add another chart

Multiple charts are used to narrow or increase the number of SQL statements and statistics that can be viewed.

To add another chart

  1. Click image\B_AddChart.gif.

  2. Select the statistic from the field at the top of the chart.

  3. Adjust the No. of Top Consumption SQLs or Percentage slider.

Select the SQL Filtering Criteria

Two options are provided at the left of the window for toggling the filtering criteria for displaying SQL statements and Transact-SQL.

Show SQL Satisfying All Charts

The SQL statements can be selected for display using the AND operator to require that all SQL statements must be in the No. of Top Consumption SQLs for each charted performance statistic.

To select only those SQL statements in all charts

Click image\B_AND.gif.

Show SQL Satisfying Any Chart

The SQL statements are selected for display using the OR operator to allow any SQL statement in the No. of Top Consumption SQLs for each charted performance statistic.

To select all SQL statements from all charts

Click image\B_OR.gif.

View the SQL text

SQL Inspector > Scan Inspected SQL

The SQL statements that you have filtered in the Statistic pane of the SQL Inspector window can be scanned in the SQL Scanner to classify the SQL statements to help identify which SQL statements are likely to be causing performance problems.

To scan the SQL statements currently showing in the Statistics pane

If the SQL Scanner window is not opened then the Group Manager window opens so you can first select or create a group. Once you open the group, the scanning starts automatically.

Sum Statistics for a Stored Procedure

SQL Inspector > Sum Statistics for a Stored Procedure

In the SQL Inspector, when you have extracted the SQL statements from the monitoring tables, the SQL statements may have been executed in a stored procedure. You can tell whether or not the SQL statement was executed in a store procedure by looking at the SQL text. If the SQL statement was executed in a stored procedure, the whole procedure will be displayed as the SQL text.

You have the option to display the statistics for each SQL statement in a stored procedure individually or to display the statistics as a sum of the SQL statement executed in the entire procedure.

To toggle between display the statistics for each SQL statement or to sum all SQL statements in a stored procedure

Click Sum Statistics for a Stored Procedure image\B_SumProcedure.gif.

When you are displaying the statistics for the individual SQL statements, the line number column will be shown in the statistics grid. This number indicates the line in the stored procedure where the text of the SQL statement begins. This column is not displayed when you are displaying the statistics for the entire procedure.
