I am trying to get a record count of this table and i get 2 different output , select count(*) shows 68560 and after updating the stats the NUM_ROWS shows 68323, why the difference .
SQL> select count(*) from dcepcd;
COUNT(*)
----------
68560
SQL> select num_rows from dba_tables where table_name='DCEPCD';
NUM_ROWS
----------
68323
Detail table will look like below:
Product_id issue_date action_date Force_date
1 10/10/2012 10/10/2012 10/10/2012
2 10/10/2012 10/10/2012 10/10/2012
3 10/10/2012 13/10/2012 15/10/2012
[code]....
Need the data like
Issue_date count_action_date count_Force_date (diff(action_date,force_date) 1 2 3 4 5 6(days since over)
10/10/2012 3 4 1 4 2 1 0 0
How to get the data like this? automatically how to get 123.... and how to calculate the difference by which day the count of difference is going?
When we execute select count(*) from table_name it returns the number of rows.
What does count(1) do? What does 1 signifies over here? Is this same as count(*) as it gives the same result on execution?
difference between count(1) and count(*). As i know count(*) will give number of rows irrespective of null and count(1) will not count the null.My Oracle version is 10 g.

SELECT COUNT(*) FROM APP.Big_table; Number of record--222653402
This is a big table to get the it's taking 8 minutes time, so that I tried the following SQL to get the count quickly.
SELECT num_rows FROM all_tables WHERE table_NAME='BIG_TABLE'
and owner='APP'; --Number of records 237213998
But I got the different count for the two SQLs. Why there is a difference in the count. Which one is correct.

Find the date difference. I need to find that how many days the task is pending, if ACT_NAME field switching from 'SET PENDING%' to 'RESUME PENDING%' by using ACTIONTAKENDATETEXT field in the History table.

View 3 Replies View RelatedWe are trying insert records from a select query in to temporary table, some of the records is missing in the temporary table. The select statement is having multiple joins and union all which it little complex query. In simple terms the script contains 2 part 1st Part Insert in to temporary table 2nd part Select query with multiple joins, inline sub queries, unions and group by classes and conditions Eg. If we execute select statement alone it returns some count for example => 60000 After inserting into the temp table, in temp table the count is around 42000 why is the difference?
It is simple bulk inserts... insert in to temp table select * from xxx. also, there is no commit in between. The problem is all the records populated by the select statement are not inserted in to temp table. some records are not inserted.
Also, we had some other observation. It only happens in its 2nd execution and not its first run. Hope there might be some cache problem
Even, we also did not believe that. We are wondering. In TOAD, we tested however at times it happens. In application jar file, after "insert in to temp select * from xxx" we take the i. record count of temp table and ii. record count of "select * from xxx" separately but both doesn't match. Match only at 1st time.
i have two tables one as test_master and other one limit master.
test master table structure
ct_id ct_a ct_b ct_C ct_d ct_e...... etc
1 -- -- -- -- --
1 -- -- -- -- --
2 -- -- -- -- --
limit master structure
limit_id ct_a_limit ct_b_limit ct_c_limit ct_d_limit ct_e_limt ..... etc
1 -- -- -- -- -- -- -- --
2 -- -- -- -- -- -- -- --
ct_id and limit_id is match column used for mapping.
now i want the total count of no of records in test_master in which test_master column value not exceed limit master column limit value if any one column exceeds its limit then the same row will be in my count criteria.
how to achieve the same using sql/oracle query.

I have created a sql loader control file to load a delimeter file in a table.
The file gets loaded into the table properly, however the commit is happening for every 64 records.
My aim is to rise the commit count by 1000 records.
Our application has a homepage that displays results of several SQL statements that are defined as reports. One report in particular should only display a custom message when Count of Invoices having a particular status > 0, and not the actual invoice count itself.
I have gotten the layout to not display the count but I need to be able to display a custom message that says "Problem Invoices exist. Please see Invoices Report for more information." I've looked over the Report Attributes definition page but I cannot find how to display this custom message.

I have a fairly standard Purchase Order form which contains pre-loaded data (been uploaded from an XML file).When the Purchase Order is processed, the form updates a Price History table only if the Price on the PO_Details changes.The code for updating the price history table is contained in a PRE_UPDATE trigger on the PO_Details Data Block.
No other data changes on the PO_Details table.I now want to change this so that the Price History table is updated even if the price does not change i.e I want to create a history record for each record on the PO_Details irrespective of whether it was updated or not.
Is there an alternative trigger that I can move my code to (ie move it from PRE_UPDATE) to some other trigger that is fired for each PO_Details record even if there is no change.
I have the following case to solve:
Example Table:

Using 11gR2, windows 7 client machine. I need to update the table missing_volume (below), where I need to calculate the estimated_missing column. The calculation of estimated_missing column for current month needs previous month numbers (as commented inside the code below). I want the output like the first table. Notice the records start from January, hence estimated_missing for January can't be calculated, but for the the rest of the months it can be done by simply changing 'yr' and 'mnth' (commented inside the code towards the end).
yr mnth location volume actual_missing expected_missing estimated_missing

[Code]....
The code does calculate correct number for 'estimated_missing' as I run the code for each month, but the problem is while updating the current month it also erases the record for previous month. E.g. as can be seen below, after I updated April the column only has the record for April, previous month record is gone, similarly updating March removed February, etc. I can't understand why it's happening!! Here is the output I get:
