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 --------------------------------------------------------------------------------------------------------------------------------- 2013 January loc1 48037 24 57 2013 February loc1 47960 3660 53 24 2013 March loc1 55007 78 57 28 2013 April loc1 54345 72 58 77The code:
UPDATE missing_volume g
[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:
yr mnth location volume actual_missing expected_missing estimated_missing --------------------------------------------------------------------------------------------------------------------------------- 2013 January loc1 48037 24 57 2013 February loc1 47960 3660 53 2013 March loc1 55007 78 57 2013 April loc1 54345 72 58 77
why it's happening (I mean where is the flaw in the code) and how to get the desired output (first table).
How to achieve "Prev_Value" column as shown below without using ORACLE analytic functions
I have records stored in table for various categories and based on ID / Name / Office / Product / Category combination I want to achieve previous value column through efficient SQL query
I take a select into a cursor and process it record by record.I have to do sum based on a column and display row by row by using dbms_output.put_line .... So the sum has to happen based on a column. Based on the column value i need to display the cumulative sum as well.
Example:-
col1 col2 amount DL AADD 25 DL BBCC 10 DL BBRR 15
Sum value for DL ----- 50
TX ADED 20 TX EDWW 60
Sum value for TX ----- 80
All the above data should be displayed using DBMS_OUTPUT.PUT_LINE in a pl/sql code. I use cursor to take the values from the table but the problem i face is .... I am not able to display the sum based in the col1 values.
Since i use the cursor .. i took the col1 values in to a variable and checked every time old_variable = new_variable if yes then continue the sum else display the sum value.
once i get the above check satisfied i am loosing a new col1 row in the check. The next loop only run for the new col1 values -1( which is used in the check loop).So is there any better way to get the solution or is there a facility to store the previous loop values in a cursor ? so that i dont have to loose that one row of data.
I am not able to come up with proper loop so which can identify that the col1 has changed and you have to display the sum value.
I have a stat table that got info like login_date,user_id etc.For a specific user, i have a requirement based on the no of days difference between the current login date and last login date.
For example, Tom logged in on June 4th 2013. His previous login was May 31. So no_of_days_difference is 5 days.How to programmatically get this for each user inside a pl-sql sub block.
Practicing in VM. My question is, I deleted the physical files of the database on Sunday but I'm having physical files backup on Friday. firstly i done restore, Performing incomplete recovery , I'm getting error like "Cannot open Archive log"
On Saturday, I changed path of archive log but I'm not aware of archive previous path location. How can we find previous path location of archive log?
I am creating a record with the items - S_No, Product_Name, Selling_Qty, Price.
Checking the total qty (Tot_Qty) from the purchase stock - table1 and already sold out qty (Sold_Qty) of the product from table2.
Consider the following values: Tot_Qty = 200; Sold_Qty = 50;
Now i create a first record of the form as follows: here on selecting the Product_name from LOV, will display the Selling_Qty item - which can be edited (Selling_Qty = Tot_Qty - Sold_Qty) and its price.
Note: [value given within () are displayed automatically after selecting the prod]
My prob is, when i am entering next record, it displays the same 150 as qty, which have to be 100. After selecting the product from LOV, it should calculate & validate as shown below: which means, previous record value of Selling_Qty also have to be subtracted and displayed.
I have a sub query (already dervived from several other tables) that has a list of children in with the date they started their course (tableofchildren). Child IDs may be duplicated in this query but each record will have unique start dates per child ID.
I have a second sub query which lists workers involved with the children in the first query (tableofworkers). A worker may be responsible for more than one child but has the unique child in the record to identify involvement with the child.
I need to join these queries together to return the child's record with the WorkerName and the AllocatedStartDate of the worker who was most recently involved with the child prior to the date (EnteredCourseDate) the child started their course (OutputWanted) - the worker associated with the child when they started their course.
A couple of points - I need to deploy this into another reporting application that doesn't support cursors etc or the 'With' operator. Also, I tend to join tables/queries in the Where clause so if it's possible that way that would be great.
We want to find out difference of data for some tables between current day & previous day. We can use query with minus operation but it will take lot of time since table size is in range from 200 to 500 GB. We have to do this exercise every day.
I have a table where there is no sequence maintained and there is no time stamp column to track the inserted record.How do I find the latest inserted record in the table.
We have data as below in the table. I need the to display the records in the order based on number of NULL values and position for each record.
provide a simple query using case in ORDER BY clause.
ID CLASS NAME DIST_ID DIST_NAME 0 NULL KIRAN 0 AP 0 C1213 NULL 0 AP 0 NULL NULL 0 AP NULL C1234 NULL 0 AP 0 NULL NULL 0 AP NULL NULL NULL NULL NULL 0 C123 RAJESH 0 AP NULL C123 RAVI NULL AP
We have to give the rank based on NULL values and NULL value column position.Let us assume column positions as
1 2 3 4 5 ID CLASS NAME DIST_ID DIST_NAME
for the following three records number of NULL values are same. but positions are different.
0 NULL NULL 0 AP NULL C1234 NULL 0 AP 0 NULL NULL 0 AP NULL C123 RAVI NULL AP
Based on the column positions the ranks as 2*2+3*3=13 1*1+3*3=10 2*2+3*3=13 1*1+4*4=17
Which is having high rank (greatest number) that record should come last . The record which is having all values that should come first. The record which is having all NULL values should come last. The out put I want as
ID CLASS NAME DIST_ID DIST_NAME 0 C123 RAJESH 0 AP 0 NULL KIRAN 0 AP 0 C1213 NULL 0 AP NULL C1234 NULL 0 AP 0 NULL NULL 0 AP 0 NULL NULL 0 AP NULL C123 RAVI NULL AP NULL NULL NULL NULL NULL
I have a table which is getting populated from a source. I dont have a time-stamp column in the table. Is there anyway to find the time when a record was inserted into the table?
i have form have one multi record block and sing record block. In multi record block having an item namely Excise_value. I want to find the sum of total Excise_Value for all the record. How to accomplish this.
PS: I want to use the Formula/summary property in forms
How to get the previous value of row with calling function to add value in SELECT statement for the row value.
Consider the example Table A1 having column a with values 1,NULL,NULL,NULL
SELECT CASE WHEN a IS NULL THEN (prev_row_value+function_return_Value) ELSE a END as A from A1
And my result-set should be like
a ---------------------- 1 1+(Return Value Of Function) Prev_Row_Value+(Return Value Of Function) Prev_Row_Value+(Return Value Of Function) Below is sample code but doesn't fulfill my criteria
I am loading data file using SQL Loader in TOAD 10.5.1.3 in Oracle 10g using the control file below and loading data into 2 tables post1.thead and post1.tdetl. THEAD contains item level transaction and TDETL is detail level when a transaction has a discount or promo attached to for that item. When the
LOAD DATA APPEND INTO TABLE post1.thead WHEN (1:5) = 'THEAD' TRAILING NULLCOLS (file_type POSITION(1:5)CHAR,
[code]....
A particular THEAD value may have 0, 1 or many TDETL corresponding values.below is a sample data file. When the position 21 in the TTAIL has a value of 1 or 2, then we know that there is a promo or discount applicable to the ITEM (THEAD).
What I want to acheive is to accurately reflect a TDETL to its corresponding THEAD, as both THEAD and TDETL are loaded into separate tables. How can we have the 2 records correlated?
I have a table which contains the multiple records for single ID No. Now i have to select single record which contains the latest date. here is the structure Name
Null Type ------ ---- ------------ ID_P NUMBER NAME_P VARCHAR2(12) DATE_P TIMESTAMP(6) Records---------------------1 loosi 22-AUG-13 01.27.48.000000000 PM1 nammi 26-AUG-13 01.28.10.000000000 PM2 kk 22-AUG-13 01.28.26.000000000 PM2 thej 26-AUG-13 01.28.42.000000000 PM
now i have to select below 2 rows how can write select qurie for this?
I need to get data from a table in which dates is equal from previous month. The dates in this table has a formula DD-MMM-YY (CRE_DTTM is the name for date column).
I've already achieve getting data from the previous month by using this formula:
My problem now is what if the current month is for example JAN 2011.. I need to get the data from DEC 2010. How can I query the previous year in this case?
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 need to create a query that returns record by record a field qty_progr with the cumulate qty considering previous records. The result should be the following:
