SQL History null records

SQL Developer version 2.1.0.63, converted from 1.5.
Conversion worked great, history came over. Perfect.
When I run a query and it produces the first 50 records, it logs my command in history. When I scroll down and it retrieves the next 50 records, it inserts a null entry in history. Reviewed the SQLHistory.xml and confirmed that it is storing null in the file as seen below:
     <ROW>
          <SQL><![CDATA[null]]></SQL>
          <Connection><![CDATA[null]]></Connection>
          <TimeStamp><![CDATA[null]]></TimeStamp>
          <Type><![CDATA[null]]></Type>
          <Executed><![CDATA[null]]></Executed>
     </ROW>
I haven't seen anyone else post this, and I'm hoping I'm not the only one experiencing this.
Thanks for any help,
Mark

I ran into the same thing and to correct it I opened my SqlHistory.xml file and removed the following sections:
<ROW>
          <SQL><![CDATA[null]]></SQL>
          <Connection><![CDATA[null]]></Connection>
          <TimeStamp><![CDATA[null]]></TimeStamp>
          <Type><![CDATA[null]]></Type>
          <Executed><![CDATA[null]]></Executed>
     </ROW>
Once I removed all those I restarted sql-developer and it doesn't seem to be creating any more of those entries.

Exel to SQL DFTask loads some Null records

I have an SSIS package to import Excel data into SQL. When I look at Excel I dont see ANY Null rows. However when I run the SSIS package and check SQL, It loads some NULL RECORDS IN SQL. WHy is that It loads Null records in SQL, When i cannot see the Null
recs In Excel?

That's because the person who created the Excel file and added the data to it pressed the "Enter" key on some of the empty cells under that specific column. In excel, such a row might look like any other empty, non-data row but for SSIS, its an
actual data row except that it doesn't have any value. SSIS treats a missing data value as a DBNULL and that's what you saw.
There are multiple ways of fixing this.
1. Educate the creator of the excel to be more careful at the time of data entry.
2. Make that target column in the DB table as NOT NULL.
3. Handle such "empty" data values as exception inside your SSIS (using a data flow task and ignoring such rows).
4. Switch to using CSV file format instead of excel format.
5. All of the above :)
Hope this helps.
Cheers!

EA3/EA2 - SQL History Timestamp column

The formatting of the Timestamp column in the SQL History now uses the NLS Timestamp Format (yay!), but unfortunately does not cope with the seconds component of the format:
NLS Timestamp Format is DD-Mon-YYYY HH24:MI:SSXFF
Timestamp column in the SQL History displays as 25-Feb-2008 15:03:.
I assume from what has previously shown in the SQL History timestamp column (2/25/08 3:03 PM) that we do not record seconds in the SQL History timestamp. I don't really have a problem with that, but can we please trim the second and sub-second components from the format?
theFurryOne

Just to add, this specific problem has been fixed. Hiding of sec/mill-sec information is handled by ignoring 'S/F', '.X', ':X' fields . But keeping the bug open so that a more generic fix is made which will handle symbols like '#SSXFF' in time field.

EXEC SQL insert null date

Hello,
Could anyone please tell me how I can insert a null date into an oracle table dynamically? Here are my codes:
DATA: LV_KEY(10),
            LV_DATE TYPE D.
TRY.
EXEC SQL.
    INSERT INTO Z_ORACLE_TABLE
    ( KEY_FIELD, OPTION_DATE )
    VALUES
    ( :LV_KEY, TO_DATE( :LV_DATE, 'YYYYMMDD' ) )
ENDEXEC.
ENDTRY.
Somehow, Oracle gives an error if LV_DATE is initial ('00000000'), saying the date is not between -49xx to ....
I could have done the following but it is kind of dumb:
TRY.
IF :LV_DATE IS INITIAL.
    EXEC SQL.
      INSERT INTO Z_ORACLE_TABLE
      ( KEY_FIELD, OPTION_DATE )
      VALUES
      ( :LV_KEY, NULL )
    ENDEXEC.
ELSE.
    EXEC SQL.
      INSERT INTO Z_ORACLE_TABLE
      ( KEY_FIELD, OPTION_DATE )
      VALUES
      ( :LV_KEY, TO_DATE( :LV_DATE, 'YYYYMMDD' ) )
    ENDEXEC.
ENDTRY.
Thanks in advance for any suggestions.

Hi Sau Tong Calvin,
don't you mess up INITIAL ans NULL values.
In ABAP, every data type has an initial value. As opposed to other programming languages, all variables are set to their initial value before use, numeric fields get 0, TYPE N which is numeric character will take 0 in all places, strings are empty and character fields are space. ABAP date fields are type N technically, so will be '00000000'.
You can store as this using open SQL.
NULL value means there is nothing stored for this field - this may save disk space if only few records have values stored for the field. But it will make problems in a WHERE clause of selection because SPACE matches initial values but not NULL values and opposite.
I don't know too much about native EXEC SQL because I never needed in the last decade. Hopefully you can solve the task using ABAP open SQL.

Clemens

Fetching null records out of a function takes much longer than non-null

Hi,
We have a function that is called thousands of times on SQL. This function has a SELECT than can return one row at max.
We realized that when the SQL statement doesn't return any record, it takes 3x times longer in the fetch phase.
I made a simple test with three functions were each one was executed 1000 times. The first one has an extra outer join that guarantees that it always returns one record, a second one with an explicit cursor that can return 0 records and a third one with an implicit cursor that can also return 0 records.
Here is the sample test code:
DECLARE
-- Local variables here
CURSOR c IS
SELECT teste_vasco.teste_vasco1(epis.id_episode) as val
FROM episode epis
WHERE rownum <= 1000;
TYPE t_c IS TABLE OF c%ROWTYPE;
l_c t_c;
BEGIN
-- Test statements here
OPEN c;
FETCH c BULK COLLECT
INTO l_c;
CLOSE c;
          for i in l_c.first..l_c.last
          loop
          dbms_output.put_line(i || ' :' || l_c(i).val);
          end loop;
END;
The difference between the tests is that instead of calling the vasco1 function, vasco2 and vasco3 is called.

As you can see, in the first example the fetch time of the SELECT in the function vasco1 takes 0.02 seconds and 0.06 in the SELECT of the test script. This test returned 1000 non-null records.
In the tests 2 and 3, the fetch phase of the SELECT in the test script takes much more time - 0.27 seconds, despite the fetch of the SELECT in the functions (vasco2 and vasco3) took 0.00 seconds (as it only returned 1 row for the 1000 executions) and the only difference between them is the function that is called. Both test2 and test3 returned 999 null records and 1 non-null record.
How it's possible than a select null records takes much longer than selecting non-null records?
Hope you can understand the problem and thank you in advance for any help or suggestions.

Thank you for the replies...
But the thing is that the SELECT in the function is very fast and the fetch phase takes no time (0.00 second).
And, as you can see in the execution plan, there's no need for a full index scan...only a range scan is performed:
SELECT CS.DT_SET, CS.FLG_STAGE, CS.DT_WARN
FROM
CARE_STAGE CS WHERE CS.ID_EPISODE = :B1 AND CS.FLG_ACTIVE = 'Y'
call count cpu elapsed disk query current rows
Parse 1 0.00 0.00 0 0 0 0
Execute 1000 0.07 0.06 0 0 0 0
Fetch 1000 0.00 0.00 0 2001 0 1
total     2001      0.07       0.06          0       2001          0           1

1 INDEX RANGE SCAN CS_EPIS_FACT_FST_I (cr=2000 pr=0 pw=0 time=7951 us)(object id 688168)
But, the fetch phase of the SQL that calls the function that has this query takes 0,27 seconds.
As far as the contex switch, we are aware of that, but we can have modularity with this solution and the first function also have many context switching and is must faster.

Extract SQL history from 10046 trace files

Hi all,
I need to extract the complete sql history from sql trace files to "debug" a client application.
I know I can read the raw trc file and rebuild the sql history looking for the PARSING / EXEC / FETCH entries.
However, this is a very long and boring manual task: do you know if there is some free tool to automate this task?
thanks
Andrea

I agree that the 10046 trace captures everything. If I do read the raw trc file I see the DML. The problem is that tkprof's record does not record the DML (maybe it thinks that some DML is recursive sql and it gets misleaded... I am not sure) so I am looking for an alternate tool to process 10046 trace files

SQL History - purged

How does SQL Developer determine what SQL History records to retain or purge?
Over time most of the history is purged. I do have a few history records from last Spring though.
Why are some older history records saved and others purged?
I'm using version 3.0.04.
Todd

Hi Todd,
So I take it you already know about and use Tools|Preferences|Database|Worksheet|SQL History Limit, and your question pertains solely to the inner workings of respecting the history limit. It actually depends on the order java.io.File.list() retrieves the *history.xml files from (on WinXP) the C:\Documents and Settings\<user>\Application Data\SQL Developer\SqlHistory directory.
If you have old history in ...\SQL Developer\SqlHistory.xml to migrate, that could also be a factor.
Whenever the limit would be surpassed by adding new SQL (not already present in the list for the current connection), the entry at the end of list is removed and the associated xml file physically deleted from the directory. The new SQL is inserted at the top of the list and an associated xml file saved to the directory. If you execute enough new SQL during a session, all the old SQL will eventually get flushed out. So this means that, during a session, the replacement rule is LIFO on the loaded history then, if necessary, FIFO on new history.
Other options to remove old SQL:
1) Delete only the old *history.xml files (including any old SqlHistory.xml, if you have no pre-3.0 version that still relies on it).
2) Set the SQL History Limit to a low value then, after some history gets purged, back to the higher value.

Count NULL Records

Hi,
I am trying to count null records in the email field by using a running total. However, the running total is not calculating it correctly. I am using SQL Server and I have checked the database to make sure the cells are actually null and are not blank. What formula do I need to use to get the running total to work? I have tried isNull() and that didn't work. Here is my current formula:
{vwGenPatInfo.Patient_Email} = "" and
Next ({vwEncounterForms.Patient_ID}) <> {vwEncounterForms.Patient_ID}

1) Is this a running total field or did you create a manual running total?
2) Why are you comparing the next record?
3) Do you have "Convert NULL values to Default" turned on in your report or global options?

SQLException: Closed Connection, SQL state [null]; error code [17002]

Hello All,
I am supporting a Java 5 project on Tomcat. We've used Spring and Stored Procedure in the project.
Recently we deployed our application in a GoLive environment and have started seeing Timeout errors in log files. After around two days we also have to restart Tomcat as users are no more able to login to access the application.
Same application runs fine without any timeout issues on another environment.
The only difference between two environments is that the Go-Live env has a firewall between Tomcat and Database and the other environment hosts both Tomcat and Database on same machine (i.e. no firewall).
For GoLive env the only port open on firewall for JDBC connection is 1521 and is used in the connection string url for obtaining the connections.
When there is a Timeout error, the N/w admin guy observed that the JDBC connection was not attempted on 1521 port, but on some random port which is not open on firewall, due to which the Database server logs also do not show entry for this connection attempt as it gets blocked by the firewall.
I am not sure why a randam port should be used to connect when a specific port is mentioned in the connection url? Also what can be making this port switching?
Application uses Apache DBCP with Spring to obtain connections.
Has anyone experienced similar errors?
Any suggestions/help on this issue is greatly appreciated!
Many Thanks,
CD

REPORT ON PL/SQL TABLE OF RECORDS on 6i & 9i

HELLO ALL,
I Want to know if it is posible to build a report on pl/sql
table of records in developer 6i, or in 9i.
thanks

This should not happen. If you are not sure that your stored procedure is bug-free, you could generate and use stored procedures using my SQLPlusPlus and give it a try.
You can email me directly if your problem still not gets solved.

Quantity of SQL History shrinking

I've noticed since about Dec. 2006 or Jan. 2007 that the quantity of SQL History kept has varied greatly and generally shrunk. In the last five days it has shrunk from 21 days to 10 days. I currently only have 47 entries in SQL History. I estimate that I execute a minimum of 20 unique queries every business day, so a significant number of my queries over the last 10 days are missing from SQL History.
In addition, today I'm noticing that I only have entries from a single database connection in SQL History. I have executed queries against two database connections today and at least 4 others over the last week. But only one of those database connections is reflected.
I've counted the entries in "SqlHistory.xml" and it matches the number of entries I see in the SQL History dialog.
Any ideas on what is happening to my SQL History? I am aware of the bug that can wipe out all of the SQL History prior to the time when a second instance of SQL Developer is opened. In this case though, I still have 10 days of history and history for all but one database connection is missing.
SQL Developer 1.1.2.25
Oracle 10g Enterprise Edition 10.2.0.2.0 - 64bit (all databases I access are the same version)
Java 1.5.0_05
Windows XP Pro SP2
132gb free space on the drive which has both Windows installed and SQL Developer.
Pentium 4 3GHz
2GB Ram

Bill,
I assume this happened on htmldb.oracle.com. I bet one of our (necessary) cleanup jobs kicked in and purged some old statements.

Why does my history only record my last session,It stopped recording all of my history a few days ago.

Starting a few days ago my history only records my last browsing session.In other words it only records today's history.I am doing a research project and need all of my history.I uninstalled Firefox and loaded it again last night.When I checked today,yesterdays history is not there.So my history feature does not work,how do I restore this feature so that all of my history is recorded.I went into the settings and made sure that it is set to record all of my browsing history.The setting is correct.Would it be possible that I have a virus that is preventing this?
I would like to keep Firefox but if this cannot be fixed I will have to install another browser and I would not like to do this as I have been a Firefox user since 2005.

Make sure that you do not run Firefox in (permanent) Private Browsing mode and that you keep the history.
*https://support.mozilla.org/kb/Private+Browsing
*Tools > Options > Privacy: Use custom settings for history

SQL Developer SQL History no longer working 3.2.20.09.87

Hi guys, The SQL History (F8) option has started to no longer work within my copy of OSD.
it was working at one point but has gone away.
I have confirmed that "Enable Local History" is enabled and has been set for 30 days history and 50 max revisions
I have confirmed that I still have a SqlHistory.xml file located in my user\operator\AppData\Roaming\SQL Developer\ directory with entries in it (6933 rows of data)
This started to happen after I started to play with the Garbage Collection settings to reduce the memory footprint of OSD.
I have since restored all of my backed up delivered settings, rebooted and the SQL History will not show up again.
My snippets and custom reports are working and I can still see the log detail where I used to see log and sql history options at the bottom of OSD.
I'm using Windows 7 and can provide an OSD dump if it helps.
Thanks...
Tom

Hi Tom,
Be careful about which preference settings relate to the functionality in question.
1. Tools > Preferences > Environment > Local History > Enable relates to a worksheet's History tab when you File > Open
2. Tools > Preferences > Database > Worksheet > SQL History Limit relates to View > SQL History pane.
You do not say how you backed up and restored your settings during all your experimentation, but let's assume whatever you did was valid. Whenever some UI component mysteriously disappears, one thing I always check (usually just delete) is the windowinglayout.xml in system3.2.20.09.87\o.ide.11.1.1.4.37.59.48 of my user settings.
For example, I can use the SQL History pane's tab context menu to Float it, then adjust it's size by dragging it's edges down to a grey square a few pixels wide/high. Close SQL Developer, reopen, View > SQL History. Darn! Where did it go?
Hope this helps,
Gary

SQL History - returning wrong statement if history is sorted

I have searched the forum and not seen anything on this, but I have been getting the wrong SQL statement returned when I select Append/Replace.
I have statements going back to 12-Jan-06 (using 804 since 13-Jan-06, 796 since 12-Jan-06 and 715 last year), so I don't know if I have hit the aging limit or not (I think I counted 221 entries).
It seems to me that it works out the cursor position and then returns that statement number from the history - independently of resorting the history.
For example, if I sort from oldest to newest (based on timestamp) and then select the bottom statement (displays as newest) and Replace, I get the oldest statement in the worksheet. If I select the top statement (displays as oldest) and Replace, I get the newest statement in the worksheet.
This is further complicated by the fact that sorting on the Timestamp is doing an alpha-numeric sort, rather than a date sort. When sorting from oldest to newest, the bottom three timestamps are (in "oldest to newest" order) are:
1/23/06 10:58 AM
1/23/06 9:21 AM
1/23/06 9:31 AM
If I then remove the sorting, the statement returned is the correct one.

It was great to get the fix for the SQL History returning the right statement if sorted (we got it in v1184).
However v1215 still does a text sort on the TimeStamp column rather than a date sort, so 2PM comes before 9AM, etc.
Also, where is the format for the TimeStamp column coming from? As someone who doesn't live in the US and thinks that days should come before months in date formats (ie DD-Mon-YYYY), I am frustrated by yet another product that uses MM/DD/YY, despite my best efforts at telling it otherwise.

SQL History and timestamp order

Hi, I have SQL Developer 12.84 (4.0.0.12).
Sql history forces MM/DD/RR format in Timestamp instead of NLS format: DD.MM.YYYY HH24:MI:SS.
As a consequence the sort order fails.
Played with C:\Users\<user>\AppData\Roaming\SQL Developer\SqlHistory files but each new entry ignores manual date changes and writes timestamp in strange format.
Any idea?

Already identified by developer team as:
Bug 17740406 - SQL HISTORY TIMESTAMP NOT SORTED AS DATE FOR NON-US LOCALES
Info based on: https://forums.oracle.com/thread/2601066 (why new thread)
This is important drawback in SQL Developer 4 for non US users. BTW, still not fixed in build 13.30 (4.0.0.13)
