SQL & PL/SQL :: Result Be Only One Record With Max LICENSE_EXPIRE_DATE
Apr 13, 2010
i have this query
SELECT V.VEHICLE_CODE VEHICLE_CODE,MAX(L.LICENSE_EXPIRE_DATE) L_EXP_DATE
,L.LICENSE_PLACE
FROM VEHICLES V,VEHICLE_LICENSE L
WHERE V.VEHICLE_CODE = L.VEHICLE_CODE
and V.VEHICLE_CODE='14'
GROUP BY V.VEHICLE_CODE
,L.LICENSE_PLACE
that should result the max "LICENSE_EXPIRE_DATE" for this "VEHICLE_CODE" it gives me two record
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 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:
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).
I got a two tables, table the_table_1 consist of customers and the other one the_table_2 consist of channels.
And I need to get list of channels by contract which are an assigned to customers.
The select below give me a only assigned channels but I need to get a contract_key too from the_table_1.
select o.channel_name from the_table_2 o minus select o.channel_name from the_table_1 a, the_table_2 o where a.contract_key=237092201 and a.offer_channel_key=o.OFFER_CHANNEL_KEY
And the select under (after minus) gives a list of non assigned channels by contract_key:
select o.channel_name from the_table_1 a, the_table_2 o where a.contract_key=237092201 and a.offer_channel_key=o.OFFER_CHANNEL_KEY
I want to run below query to get the result set that I am after. But It takes long time even with the indexes...Here in IM_Mapping table is having 1.7 mio records and T_Extract table about 35000 records. All the other tables having below 1000 records

Middle EastThe table contains more than a million records, pivoting using a group by clause will have performance issues. Would it be possible to do this with Xquery or any other method?
I need to return the stored result in a record by ref cursor. In the below code I am displaying the result through DBMS_OUTPUT.PUT_LINE but i need to do it through ref cursor to display the result.

I need to write a query which will get me output: 233445, i.e. all the three rows concatenated. How can it be done? I want to do it through sql only and not to use PL/SQL. Is this possible?
I have the following data (columns IDx, STARTx and DURATION) and want to create the column RESULT. Example:
create table zTEST ( IDx number, STARTx number, DURATION number, RESULT number ); insert into zTEST (IDx, STARTx, DURATION, RESULT) values ( 1 , null , null , null );
[code]...
The logic behind the table is like this: when there is a Start-ID and a Duration, the field Result shall show the Start-ID for the next records (Duration period). Even if there is a new Start-ID in row 9, it is ignored since threre is already a current signal from row 6 which is still running.
select dem.NUM_PCE, memo.comment from demand dem, dem_comment memo where CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE) = memo.parentId (+) and memo.dateCreation = (select MAX(DEM_DATE_CREATION_MEMO) FROM dem_comment memo WHERE memo.parentId = CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE))
I should have a result with this request but there's nothing and the problem come from the fact that when the following condition is not met, there are no resulty even if there's an outer join
and memo.dateCreation = (select MAX(DEM_DATE_CREATION_MEMO) FROM dem_comment memo WHERE memo.parentId = CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE))
This condition makes Oracle ignores the outer join..I have tried to add this:
select dem.NUM_PCE, memo.comment from demand dem, dem_comment memo where CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE) = memo.parentId (+) and (memo.dateCreation = (select MAX(DEM_DATE_CREATION_MEMO) FROM dem_comment memo WHERE memo.parentId = CONCAT(dem.NUM_PCE,dem.NUM_DEMANDE)) or memo.dateCreation is null)
but there are too much records and the result is not consistent
For obscure test purposes I need to modify an existing SQL query to emit the rows N times instead once. I'm aware of the possibility to "UNION ALL" the query with itself to get the all rows twice.
But as I require the resulting rows to be emitted around ten to hundred times this approach doesn't seem sensible to me. Not to speak of the missing possibility to parametrize the number of "repetitions".
I have a sql query which fetch the data from 4 different tables. I want to write the output of that query into a excel or a CSV file without using TOad and all. Let me know is it possible via creating function or procedure.
i want that when i run above query every time bas_cod column should start with difference value. now it is starting from 1, i need when i run next time it should start with another number except 1,
i mean whenever i run above query,order of bas_cod must be change from last.
