SQL & PL/SQL :: Rows With Same Date - Count Date Only Once
Jan 18, 2011
I'm trying to run a script that will sum column values from a table using only a certain period of time in example below only January submissions. However, some of those rows have the same date and I want to have the latest time row of that day in the count.
We have a table with timestamp column and having millions of records.We want to create a materialized view or query, which can give count based
-on some group by columns from table and -group by on condition (if count > 1000) and -group by on condition (if timestamp range for that group is > 1hr)
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.
Example as needed: NoPendingDays = 23 (8+15)
I have attached Create table and Insert table values sample as SQL file.
I am trying to run the following queries in my database.
Q-1)select * from item where trunc(approval_date)='21-MAY-13' When Q-1 is executed it returned row that has approval_date of 21-MAY-13 from database. Q-2)select * from item where approval_date=to_date('21-MAY-13') When Q-2 is executed it says no rows selected.
I am trying to retrieve all rows with the date of May 23rd, 2008. Our data is stored with the date and time.
How do I format the where clause so that the time is taken off? I am still a newbie with oracle and what I have is this:
Select Distinct Table1.*, Table2.* from Table1, Table2 where Table1.file_name = Table2.file_name and Table1.downloaded_date = Table2.date_loaded and downloaded_date = '23/May/2008'
Of course, it's the last line not working because I don't know how to format it and no rows are retrieved when there are definately May 23rd rows stored in there.
I'm looking to see if there's a solution to my problem that I can use within the context of my business application interface into an Oracle RDMS. I have access to write custom SQL statements and functions, but I am NOT able to create stored procedures using the interface I have.
The challenge I am having is comparing date ranges. I have a table containing two columns labelled START TS TIME and END TS TIME, both of type 'Date'. I have figured out how to query each row against a given Next Session Start and Next Session End and determine if each row overlaps that row.
I need a procedure that will be recursive: that is, set Next Session Start and Next Session End to START TS TIME and END TS TIME of the first row, compare all rows against it, then set Next Session Start and Next Session End to the next row, compare all rows, ... for all rows in the table. I want to know what the maximum number of matches is (i.e. the most time periods that overlap).
If I could use a stored procedure I could complete this query easily. Is there other techniques (i.e. functions) available to leverage in order compare each row of date ranges against ALL rows in the same table?
Version : 4.1.1, I have a tabular form on a DB table. One of the columns is a date field. When the user hits the "add Row" button on the tabular form, I want the Date field to be defaulted to sysdate. Here is what I have tried so far,
1. Created a "hidden" item P1_SYSDATE and populated the default value with sysdate. After this, under the DB tabular report date field, I used default type - Item/application on this page and entered P1_sYSDATE
2. Instead of populating the default value of the P1_SYSDATE hidden item, I created a before regions process and added
:P1_SYSDATE := sysdate
and added P1_SYSDATE to default type of the tabular date field with default type as "ITem/application on this page.
I get the error
ORA-01790: expression must have same datatype as corresponding expression
I tried to_Char(sysdate,'dd-mon-yyyy') and then converting it back to to_date. still no luck.
When I run a query form the the Query Window in Visuial Studios 2012 all the date fields truncated to 'mm/dd/yyyy', but i need the full date returned. I am able to get full date from TO_char(MyDateField, 'yyyy-mm-dd hh24:mi:ss'), but if I do TO_DATE(MyDateField, 'yyyy-mm-dd hh24:mi:ss') it only returns 'mm/dd/yyyy'. I'm sure this is a simple setting in Visual studios but I cant find it to save my life. Is there there a way to have the full date returned by default?
Due to some business requirements a table field needs to change from date to timestamp in order to handle the millisecs.
1>When i alter the row , for a table with 150 million recs will there be a conversion. Is there a recommended way to convert the field. Mind you this field is used as a part of composite PK.
2> There is a interfacing application which connects and copies the data to its system and is using the date type, will that application be able to continue to work without any changes, if it does not care about the millisecs.
3> Will there be performance impact on an existing application that uses the date field to sort
I want to get top two rows based on ACCT_UNIT & order by status_date, if there is only one row on acct_unit, get one row. IF more than two rows available, want to get the top two rows based on status_date.
->Col1 with experience in years entered as an integer ->Col2 with current date
I need to add another column as a date value adn for that i need to subtract Currentdate-Col1 when i tried currentdate-Col1 it just subtracted the days i need the formula to subtract years and give a date
I have worked in DB2 and all u need to do there was add the keyword years at the end but in oracle the same does not work
I would like to inquire how do I code my select statement if my user enter a search date range(search startDt: 01/08/2012 and search endDt :30/09/2012) and I will like to retrieve only the 7records out from my table as shown below ?
Write a program to declare a date variable and assign it to the current system date. Depending on the day of the month the program should print the following:
If day is 1-10 then print "It is day<day number> of <month name>. It is early in the month". If day is 11-20 then print "It is day<day number> of <month name>. It is the middle of the month". If day is 21-31 then print "It is day<day number> of <month name>. It is nearly the end of the month".
For example, if the day is November 30, then print "It is day 30 of November. It is nearly the end of the month".
How can we partition a table based on date if it does not have a date column.
Actually I have to compare two tables on daily basis and fetch few rows from those two tables and enter it to a third table.But both these tables does not have a date column.
I am confused if i need to alter those tables and add date column or if there is some way in which i can compare the data from the two tables for that particular day only and not the whole table data.
My requirment is to find out the period names and transactions which are in valid date formats and are less than sysdate and the non date formats are adjustments made by different users for their transactions

I want to get data for month to date. For example, If I pass today or any day date as parameter then i should get data for that month(month of passing date) up to passing(parameter) date. As well as i have to get year to date.For example, If I pass today or any day date as parameter then i should get data for that financial year(year of passing date) up to passing(parameter) date. how to get month to date and year to date data.
A field named xxx_date is a text item which we have to enter manually so as to update a record in that particular date. This is a mandatory field without which we cannot continue the data entry..
I am getting this error while trying to update the record
FRM-40509 :Oracle error :unable to update record
I have kept the enabled = yes required=no data type=Date.. in the property pallet
I want to reset my date to this format: 12/31/2012 11:59:59 PM - see code below:
DECLARE v_latest_close DATE; BEGIN v_latest_close := TO_DATE ('12/31/2012 23:59:59 ','MM/DD/YYYY HH24:MI:SS'); DBMS_OUTPUT.PUT_LINE('The new date format is : '|| v_latest_close); END;
the code above displays only : 12/31/2012 instead of 12/31/2012 11:59:59 PM
