"Count" from Toad table menu return 0 records, bug

damir.vadas_250 · September 28, 2016, 1:31am

Hi,
Toad 12.9.0.71 x64
Oracle client 11.2.0.3.0 x64
Oracle DB 12.1.0.2.0 - x64

Situation real (from SQLPlus)

SQL*Plus: Release 11.2.0.3.0 Production on Wed Sep 28 10:23:09 2016

Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options

10:23:10 >
10:23:10 >SELECT /*+ PARALLEL(4) / count() from RTX_STAGING;

COUNT(*)

64437857

Elapsed: 00:00:19.47
10:23:29 >

And from the Toad, shows 0 records (have checked,refreshed several times...)

SQL spool shows:

Session: Q383211[A1_FAS]@FMS
Timestamp: 10:33:27.926
select count(*) from "A1_FAS"."RTX_STAGING"
Error: ORA-08103: object no longer exists

What i know is that another session in background are dropping partitions (a lot and very often!) and this somehow reflects on Toad execution.
But, Oracle SqlPlus* works OK!

Hope this helps,
Damir

I just did a google search on that error code and found that it’s not uncommon to get an ORA-08103 when SELECTing from a table that is undergoing partition maintenance. I don’t know of any way to avoid that error in Toad. Remember, it’s Oracle that runs the SQL and returns the error. Toad is just the messenger.

I noticed that in SQLPlus you included the parallel hint. If you run Toad’s query in SQLPlus, do you get the error in SQL*Plus? What about when you the query with the parallel hint in Toad’s Editor?

One thing I will add though - is that if Toad is getting the error, it should show it instead of “0 records”. I’ll take a look at that.

Hi John,

Sorry was on some meeting and later test this case more properly…

Problem is persistent (not TOad related!) if while query runs other session drop partition which is in plan (and invalidate index) then oracle has report an error even in SQLPlus.

I just tried this:

in SQL*PLus: create table X as select * from dba_tables;
in Toad: go to table X in the schema browser, go to the data tab.
in SQL*Plus: drop table X purge;
in Toad, right-click in the grid and choose “record count”.
It gives me the “table or view does not exist” (which is a different error than yours, but it should lead to the same result for record count), THEN I get the “record count: 0” dialog.

I have made a change so that the “Record count: 0” dialog will not be shown in this case. Did you ever see the error message?

Posted 2 times today and still toad forum delete all mine posts…crazy…

Let us try 3rd time:

It is partitoned table and other sessions are dropping partitions a lot in background. So when oracle start to count using PK, it get an error. here is part of the trace:

Hope this helps now and forum will leave mine post now…

John,
maybe you didn’t noticed from mine first post:

Toad “SQL spool” shows this:

Session: Q383211[A1_FAS]@FMS
Timestamp: 10:33:27.926
select count(*) from “A1_FAS”.“RTX_STAGING”
Error: ORA-08103: object no longer exists

And thi serror is in the trace as well … but this is partition level …not the whole table.

JohnDorlon · September 28, 2016, 12:24pm

I did get that message earlier by email. I don’t know why it didn’t stick in the forum.

Please see my last reply: I saw error message followed by “record count: 0”. Did you ever see the error message in Toad? Next beta will only show error message.

JohnDorlon · September 28, 2016, 12:26pm

I did see that. You should see an error message no matter which one it is. I dropped the table just because it’s easier.

damir.vadas_250 · September 28, 2016, 12:33pm

No error as shown on the screen shot
