In Toad for Oracle 12.12 and prior, the Trace File Browser's "Statement Details" tab shows statements:
That last point is the main focus of this blog and the recent changes. Take a look at the screen shot below, and notice that the same statement is repeated several times.
The current display is nice in that, going from top down, you can see what happened, in the order it happened, in a session. But if these identical statements weren't right next to each other, you might not notice that the statement was repeated. Sometimes repeated statements will appear as the same cursor executed multiple times and sometimes they will be separate cursors, each executed one time. It would be nice to be able to see a summary of these identical statements, regardless of if they were the same cursor or separate cursors. So that's what's done for Toad 13 - beginning with 126.96.36.199.
In Toad 13, I've renamed "Statement Details" tab is to just "Statements", and I broke it out into two sub-tabs. The first tab is labeled "By Recursion". The "By Recursion" tab is what you've always seen in the Trace File Browser. The second tab "By SQL ID", adds an additional section at the top which summarizes each unique SQL Statement in the trace file. There are just a few columns in the top section. They are:
Of course, you can click the column header to sort by any of these columns.
Once you select a statement, the cursors for that statement are shown in the middle section (which has the same columns as the listing of the "By Recursion" tab, the same columns that you are used to in the Trace File Browser, except with the "SQL Text" column no longer visible by default, since it is just a repeat of whatever you've selected on top. The bottom section is what you are used to seeing at the bottom of Trace File Browser (SQL Statement, Explain Plan, Parses, Executions etc)
OK, enough talk. Here's the same file opened in the new Trace File Browser, with the same statement selected. See how it's listed only once in the top? The numbers you see in that row are totals over all of that statement's cursors. Each cursor for that statement is in the middle section, and whatever cursor you select in the middle is detailed in the bottom.
So it's not a huge change in terms of the look of the Trace File Browser, but hopefully it will give you a better understanding of your trace files.
Some other minor changes:
That's it for now. Let me know what you think!
