SQL & PL/SQL :: Missing Values In Database?
Nov 22, 2012
i´ve got a table with colomns (time, value) ... for example:
time value
10:00 10
11:00 20
12:00 25
13:00 28
15:00 31
17:00 38
you can see, that the row 14:00 and 17:00 are missing. How i can create the missing values? The value should be the value from the last point. The result should be this:
time value
10:00 10
11:00 20
12:00 25
13:00 28
14:00 28
15:00 31
16:00 31
17:00 38
How can i do this ?

As data completeness, data consistency, data integrity are some of features of good quality data. What is best approach and best practice to deal with missing or null values in database? I am facing such type of situation. In a main table, there are several columns have null or missing values.
Get rid of null or missing values. Should I consult source documents from where data was fed into database to achieve maximum data completeness?

I performed a switchover test of my Exadata databases last night. Both databases are running 11.2.0.2 (BP7) on top of GI of the same version.I'm using Data Guard Broker to administer the Data Guard configuration.
I have, as you'd expect, the standby_file_management set to AUTO, so any file changes/additions/deletions that are made on Primary should be applied to Standby also.And they have been. Until last night.
When I had switched over to running Primary on the Standby site, I got this error message:
Tue Jun 04 22:27:12 2013
Errors in file /u01/app/oracle/diag/rdbms/exdw1pdg/exdw1pdg1/trace/exdw1pdg1_ora_26630.trc:
ORA-25153: Temporary Tablespace is Empty
I checked and my two temp tablespaces existed, but had no files in them. These files are 200Gb and 448Gb in size, so you'd think you'd notice them going missing. This wasn't by any means the first time we switched over (and, yes, I did create temp files for Standby when I built it and first switched over)
We've switched over to Standby multiple times and even ran a whole day's processing against it and haven't seen this. Ultimately, it wasn't a big deal, because I just created a tempfile for each of the tablespaces and off we went.Nothing in MOS seems to mention something like this. Basically, it looks like the switchover process decided to eat my tempfiles but keep my temp tablespace defintion. Odd.

We have a custom portal application that uses a bunch of application servers. Our connection pool max size is 1100. For the past two days, we had two incidents when the cpus reached the max limit and the db was not allowing connections to come thro' for 10 minute periods. The alert log does not have any entry and the listener log does not have any entry for that 10 minute period.

OS: Solaris
DB: Oracle 11.2.0.1 EE
Not Using ASM or RAC
I have a Production database that is in archivelog mode and a Standby DR server. Both servers (Prod, Standby) have exact same structure and db name/version.
We manually scp archive logs and recover them to a manual standby database via SQL Scripts "cron". (I.E. set autorecovery on; recover standby database;)
We recently got out of sync with our log files and have not been applying them to the standby. As part of Prod Maintenance, these log files were deleted and are not available anymore.
I've tried several ways to "rebuild" our standby database. I have tried to Shutdown prod, backup all the db files and scp them to standby, re-create standby controlfile and startup mount and recover standby. Every time I try to apply a new archive log via recover standby, these are the errors:
ORA-00279: change 211077622 generated at 1/27/2012 12:18:42 needed for thread 1
ORA-00289: suggestion : /oradump/arch/PROD/PROD_arch_1_69486_736618850.arc
ORA-00280: change 211077622 for thread 1 is in sequence #69486
ORA-00308: cannot open archived log '/oradump/arch/PROD/PROD_arch_1_69486_736618850.arc'
ORA-27037: unable to obtain file status
SVR4 Error: 2: No such file or directory
Additional information: 3
ORA-10879: error signaled in parallel recovery slave
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/oradevices/PROD/oraPRODsystem1.dbf'
When I check v$log_history, the new logs have not been applied. I've also tried the "Restore from incremental backup via SCN" method with same results. Is there a way to re-create the standby clean and ensure that the log chain that is currently broken gets fixed or reset? I would eventually like to get DataGuard in here, but that's not the case at the moment.

We have database with multiple fields containing NULL values and in many queries we have NVL function which in turn is suppressing the index usage when in fact it is really essential (selectying very few rows from massive data) instead of creating lot of Function based indexes (NVL) or composite indexes with (nullable_column, constant) I am thinking of settting a default value for most of the fields In that regard I have some queries :
Which approach is better - setting default value for the fields or updating the fields with default value and modyfing inserts to take care of future data? Though altering table and modifing column to set default value looks better considering it will take care of data inserted in the future, it will invalidate the subroutines.I understand in 10g both statement will generate lot of undo (though in 11g, I heard things changed for setting default value of a column) How to take care of all the queries which are using the criteria 'where column1 IS NULL' or 'where column1 IS NOT NULL'. It will be really difficult task to manually change each and every occurrence of such condition even using user_source.
Finally for numeric values say for ID field which starts from 1 onwards 2,3,4 etc, we can set 0 as sensible default so that the performance is not affected.
Is there such precaution for varchar2 field purely from performance point of view?

I have 3 tables in the Oracle database( emp, employee, emp1) which has following record values in it.
empidenamejob
7369, 'SMITH', 'CLERK'
I would like to list these 3 tables thru SQL/PLSQL, having the above record values combination. Also, the name of the columns could be different in all the tables i.e. name could be 'ename' in Emp table , and 'name' in Employee table. Is there way to do this in SQL or PLSQL ?

When I view Database Throughput Metric Data, e.g. Consistent Read Gets (per second) using "Real Time: 30 Second Refresh", it appears that timestamp are 5 hours behind the current time. This can be also observed by "Last Upload" timestamp from "All Metrics" view of the database instance for "Throughput" Metrics.
It was not like this for EM GC10.2.0.2. I'm wondering if anything changed in GC 11g.
I even tried to set low alarm thresholds for "Consistent Read Gets" metric, it doesn't seems to work on the timestamp of the realtime data.

Application Express ver. 4.1
I have created a form. Some of the elements are hidden such as updated_by and update_date. I have provided the default values for these attributes as pl/sql expression in the "default section" (Application->page->edit page item). I am using the Process Row process that is automatically created when a form is created.
The problem is when I click the update button, the updated_by and update_date is passed as null values which throws an error from the database.

I used Region, Process by to search the report which appears as shown above. Then I use Choose Auditors column to select my Auditor and copy paste it into the report under To be Audited By col. Is there a way to automate the process. I am here using a tabular form in APEX. My main aim is to assign auditors based on Region, not equal to Processed by.

I have a scenario where I have to get all the available dates of a resource. I am using the below query to get it.
Select Avail_Date AS MONTH
, Resource_Id
FROM res_tsk
, (SELECT Rownum - 1 + TRUNC (sysdate) avail_date
FROM Dual
[code].......
The result of this is:
Month Dates Resource_ID
12/3/10 0:00 NULL
12/4/10 0:00 NULL
12/5/10 0:00 NULL
12/6/10 0:00 100033868
As I am doing a outer join, if the resource is not available on a particular day the resource_id is coming as NULL as it is not available. Is there any way to populate this NULL resource_id with the original resource_id as the resource_id is same for all the result set.
I need the output to be
Month Dates Resource_ID
12/3/10 0:00 100033868
12/4/10 0:00 100033868
12/5/10 0:00 100033868

My scenario is to insert values into 'out' column by comparing 's' and 'IP' columns of temp table.The exact situation is at first need to go to ip column,take a value and then go to source column and check for the same value of ip which is taken previously.Then after corresponding ip of that source column should be inserted back in previous source column.
The situation is marked clearly in file which i am attaching with '--' comments at respective places.I am also pasting the code which i tried out,unfortunately it is giving error as exact fetch returns more than requested number of rows since there are duplicates in the table.I tried it using nested for loops.Also implemented using rowid,but it didnt work.
fixing the errors or if there is any new logic that can be implemented.
DECLARE
i_e NUMBER(10);
BEGIN
FOR cur_1 IN(SELECT IP from temp where IP IS NOT NULL)
LOOP
FOR cur_2 IN(SELECT IP from temp where s=cur_1.IP)

I have been looking at this now for a good 2 hours. It seems like a simple error but I just cant see it. I must of counted the brackets 20 times. I have run this code in SQL developer using actual values and it works fine.
If your wondering about the esig class it just runs the sql with a few other SQL statements. I have changed the code below to a SELECT * statement just so see if it was actually that statement that was the problem. The select worked so it must be this.
