conditional merge based on the date

Need help on a merge statement. I need to merge two dataset. But when the key match, I also need to cpmpared the date before I merege it.
See code below
drop table x1;

drop table y1;

select * from x1;

select * from y1;

create table x1 (id number,name varchar2(10),cdate date,status varchar2(1));

create table y1 (id number,name varchar2(10),cdate date,status varchar2(1));

insert into x1 select 1,'A',sysdate - 100,'Y' from dual;

insert into y1 select 1,'A',sysdate - 50,'N'  from dual ;--should change x1.status to y1.status  and x1.cdate to y1.cdate as y1.cdate > x1.cdate

insert into x1 select 2,'B',sysdate - 20,'Y' from dual;

insert into y1 select 2,'B',sysdate - 120,'N' from dual ;--should leave status in x1 alone

insert into y1 select 3,'c',sysdate - 10,'Y' from dual; --should do an insert on x1 

commit;

--how do I do a conditional merge (key=id,name)
-- based on the cdate. If y1.cdate >= x1.cdate then take the y1.status  and y1.cdate

--desire output
select * from x1
1     A     01/01/2012 10:54:35 AM     N
2     B     1/31/2012 10:54:37 AM     Y
3     C     1/31/2012 10:54:37 AM     Y

Hello

You can add a WHERE clause to the WHEN MATCHED THEN UPDATE section.

WHERE   x1.cdate  < y1.cdate

Thanks for posting the CREATE TABLE and INSERT statements; It is very useful. It would also help if you have validated your MERGE statement, even if it does not work perfectly.

  • How to plan the report filtered by dynamic date based on the date, the Agent is running

    Hello

    I have a question about account using OBIEE agent.

    If I run an agent today to deliver A report, can I me A report based on the date of last Monday or any dynamic dates?

    For example, say is today, December 18, 2013, and my agent is run according to how I put the calendar. Now the content of the delivery report one being delivered. Now A report has a date column, normally this column is filtered by the current date. But if it comes through the agents to different users, the data should be the previous Monday, so in this case, 9 December 2013. When this agent is run once again, declared December 27, 2013, then the report must be filtered by December 16, 2013, which is the previous Monday 27 dec.

    Something like this is possible in OBIEE 11 G?

    Thanks in advance.

    Yala,

    Not in a straightforward way

    (1) let the report through Agent with filter current Date

    (2) after he ran for the first time you can see IBOT name/last execution time (LAST_RUNTIME_TS) in S_NQ_JOB

    Create a variable reference 'last_run_agent' to aid in sql to get max (LAST_RUNTIME_TS)

    SELECT max (LAST_RUNTIME_TS) from s_nq_job, whose name = "AGENT_NAME;

    Change analysis with current date filter report and amend accordingly the condition of filter to filter on repository variable, newly created

    Thank you

  • Find (weekly) missing date ranges based on the Date of submission

    Nice day:

    I have a table that contains the data with a date of presentation of the report column.  If the requirements are that each employee must submit at least 1 weekly report beginning January 1, 2015, how can I find the weekly reports missing, based on the date of submission of reports.

    The ideas that I had:

    • Left join by partition by date (range between)
    • Create a date dimension view?

    Of course, I'm not sure how to approach this dilemma without creating a query of Monster.  Sometimes the simplest queries mistake me...

    Thank you, Aqua

    Here are the DDL for the table with the information from the presentation report (example):

  • Get the old value and the new value based on the date

    Hello

    I have a table called list created below with the rest of the insert statements.

    CREATE TABLE ROSTER
    (
    NUMBER OF ROSTER_EMPLOYEE_DEF_ID
    NUMBER OF EMPLOYE_ID
    NUMBER OF DEFINITION_REGION_CODE
    NUMBER OF DEFINITION_DISTRICT_CODE
    NUMBER OF DEFINITION_TERRITORY_CODE
    START_DATE DATE,
    END_DATE DATE
    )



    INSERT IN THE LIST
    (ROSTER_EMPLOYEE_DEF_ID, EMPLOYE_ID, DEFINITION_REGION_CODE, DEFINITION_DISTRICT_CODE, DEFINITION_TERRITORY_CODE, START_DATE, END_DATE)
    VALUES
    (1,299,222,333,444, 'JUNE 1, 2011', 30 JUNE 2011 "")

    INSERT IN THE LIST
    (ROSTER_EMPLOYEE_DEF_ID, EMPLOYE_ID, DEFINITION_REGION_CODE, DEFINITION_DISTRICT_CODE, DEFINITION_TERRITORY_CODE, START_DATE, END_DATE)
    VALUES
    (2,299,223,334,445, "1 JULY 2011', JULY 20, 2011" "")

    INSERT IN THE LIST
    (ROSTER_EMPLOYEE_DEF_ID, EMPLOYE_ID, DEFINITION_REGION_CODE, DEFINITION_DISTRICT_CODE, DEFINITION_TERRITORY_CODE, START_DATE, END_DATE)
    VALUES
    (3,299,224,335,446, 'AUGUST 1, 2011', AUGUST 30, 2011 "")

    INSERT IN THE LIST
    (ROSTER_EMPLOYEE_DEF_ID, EMPLOYE_ID, DEFINITION_REGION_CODE, DEFINITION_DISTRICT_CODE, DEFINITION_TERRITORY_CODE, START_DATE, END_DATE)
    VALUES
    (4,300,500,400,300, 'JUNE 1, 2011', JUNE 20, 2011 "")

    VALUES
    (5,300,501,401,301, "1 JULY 2011', JULY 20, 2011" "")


    In the table above we have columns like

    EMPLOYE_ID, DEFINITION_REGION_CODE, DEFINITION_DISTRICT_CODE, DEFINITION_TERRITORY_CODE, START_DATE, END_DATE

    The result I'm looking for the table above is based on the employe_id OF start_date AND end_date

    I need to get the OLD_DEFINITION_REGION_CODE and the NEW_DEFINITION_CODE
    Similarly, OLD_DEFINITION_REGION_CODE and the NEW_DEFINITION_REGION_CODE
    and OLD_DEFINITION_TERRITORY_CODE and the NEW_DEFINITION_TERRITORY_CODE


    I need to get a row of data for each employee saying old value and the new value

    for the employee 299 there are 3 records he puts the new record which is the latest date is to say beginning August 1, 2011 and end date of recordings old 30 August 2011
    beginning July 1, 2011 and July 20, 2011


    For the data in the table above, I need to get the data as below


    EMPLOYE_ID OLD_DEFINITION_REGION_CODE NEW_DEFINITION_CODE OLD_DEFINITION_REGION_CODE NEW_DEFINITION_REGION_CODE START_DATE END_DATE
    299 223 224 334 335 20 JULY 11 30 AUG 11
    300 500 501 400 401 20 JUNE 11 JULY 20, 11


    Please suggest me to get the result above, based on the data. Please let me know if my messages are not clear

  • Creating primary key based on the Date

    Hi all
    I am trying to create a unique ID for each record, based on the date that the record is created. Example, if the folder is created today, I want to the key is 20101130XX where XX is a sequential list of numbers e.g. 01, 02, 03 etc... in the case where more than one person creates a record today.

    If 3 people created record yesterday their unique ID would be

    2010112900
    2010112901
    2010112902

    and then comes the midnight and someone creates a new record, that it would be

    2010113000

    This is intended to give each record with a unique ID that will be used to reference the ticket.

    We are already using the date format, but currently users have to manually enter the id and who can create errors such as 2011112900 when it should have been 2010112900 then instead of 2010 they put 2011

    I'm not sure how to create a trigger to generate this type of unique identification number and would appreciate any help

    Thanks in advance

    Never said it was perfect, but then again, it is a rather sticky issue... Reset sequence work would be scheduled to run @ some point... You entered in tables past 24/7? I would say that system could be locked for those 5 minutes sequence is updated, or the table is locked to allow no access while the process is...

    To be honest, that is the question in the design of a key value that is dependent on outside data, as apposed to a surrogate key, which is generated System... Again, you could have at ONCE and have the surrogate for a key key REAL primary and date + sequence as a secondary key for the use of basic unit of carbon...

    Thank you

  • Conditional formatting depends on the date ranges

    Basically, I want to be able to enter a date in column A and a sum of money in the B column, depending on where the date in column A grave in a date range, I want the money in column B to copy to a corresponding column. Is this possible? The only questions I found on here deal in a conditional formatting with dates have to do with derivative.

    Thank you

    Julio

    I hope this help to clarify for you...

    It is not bringing conditional formatting.  Formatting conditional would change the format of a cell (or cells)... as the font, color, size, color cell background, or other formatting character is tics of a cell based on the contents of the cell

    You ask about including of the value of a cel another beach under certain conditions

    Here is an example:

    The first three rows are header lines.

    You must enter a valid date for the towing job.  Using the format "mm/dd/yyyy".

    C4 = IF (AND (DATEVALUE (A4) ≥DATEVALUE($B$1), DATEVALUE (A4) ≤DATEVALUE($B$2)), B4, "")

    It's shorthand dethrone select cell C4, and type (or copy and paste it here) the formula:

    = IF (AND (DATEVALUE (A4) ≥DATEVALUE($B$1), DATEVALUE (A4) ≤DATEVALUE($B$2)), B4, "")

    Select the cell C4, copy

    Select cells C4 at the end of the C column, paste

  • The smart Albums based on the date range cause app Crash Photos

    While I'm setting up a new Smart Album based on day of photos between 12/01/2015 and 31/12/2015 the Photos app closes with a crash. Cannot set the second date (the end date for this album). However, I can easily create a new Smart Album for next month (01/01/2016 and 01/31/2016). I create smart Albums, because the new Photos app does not like the old iPhoto does with my Photos from the photo gallery.

    How can I solve this? I don't have an album of December...? !

    You are in an area where the date format is different from the United States?  Earlier this year, we have seen small business issues have reported that rules for smart albums date range do not work with the primary language set to French or German.

    Try to change the primary system language to English with an English date format. Photos could be trying to read the 12/31/2015 as the 12th day of the month 31.

    Or use a different date based on 'before' rule and after.

  • Then the validation of a detail or form based on the date picker - upper effective Date?

    Hi, creates a BP custom with the effective date in field added to my details form or higher. Can I have a set of validation rules up for my top of or the form detailed such as the effective date cannot be greater than the current date? Thanks in advance.

    For the decimal amount, you need to change the formula type, the default value is a numerical formula, but you must choose the date difference. This is the online help:

    To create a date-difference formula

    1. Open the form that contains the field for which you want to create a formula. The form designer window opens.
    2. In the form designer window, select the date field that you want to create the formula. When the calculation is performed, this field appears as read-only on the form and will automatically update each time that the fields that make up the formula change.
    3. Click the formula button. A creation of the formula window opens.
    4. In the formula field Type, choose the difference in Date in the list. The window expands to show additional fields, as shown in the table below.
    5. Click OK to save your changes and close the window.

    In this area:

    Follow these steps:

    Last Date

    Click on the arrow down. uDesigner displays the list of all numeric fields on the form. In this list, choose the field that contains the later of the two dates that will be used in the calculation.

    Earliest date

    Click on the arrow down. In this list, choose the field that contains the first of the two dates that will be used in the calculation.

    Choose the calendar days to include all days of the week in the calculation. Choose the days of work to use only the working days of the week in the calculation.

  • Textarea conditional display based on the value of the checkbox.

    Hi all

    I have a question regarding the conditional display of an article based on the value of the checkbox.

    I have a checkbox in a region, which is a STATIC LOV:; Y and the text box in the same region. Now I want to show this textarea only if the check box is selected. ??

    Please suggest how to achieve this.

    Thank you

    DC

    Hello

    I guess that you are 4.2 Apex as you haven't shared the same.

    • Create a dynamic Action on change of box which should present the value of the checkbox and update the TextArea element.
    • Then continue as conditional Textarea with checkbox value.

  • Conditional display based on the value of line

    I have a report table with several lines on it.  I need to post a link to another page of user action if a value in the line corresponds to an attribute of the user's role, so they can act on the item.  Other display or update the document would not be able to run the link.

    The logic of nickname would go something like this:

    If user_role = role_this_line_item then

    display approval_link

    on the other

    Hide approval_link

    end if

    I know how to write pl/sql to return to the display of the correct state of true/false, but I can't find out how to reference the value on the display line.  I tried: role_this_line_item, role_this_line_item, #role_this_line_item # and none of them return one value other than false.  How to refer to an attribute on the current line of the decision to hide/show correct?

    Al Wondra says:

    I use V4.2.6 Apex in local installation of Oracle 11 g XE.  I tried with IE, Firefox and Chrome.  None has the conditional display.

    The report is a standard report created using the Apex report wizard.  I'm one of the columns (the ID of the line) changing to conditionally a link to a page to data entry.  I only need one line at a time to be the active link.  No line should have a link, if the user is not the role is required to perform this action.

    You have described my question exactly, it seems, that the conditional rendering is applied to the entire column.  I need that it is applied to specific lines.  Some lines (1) will be the active link.  All other lines does not display the link.  Is this possible?

    If you want the value of the ID to display for each row returned by the report, but only rendered as a link, if the condition is true? The values used in the State come "role_this_line_item" seems to be a value of a column in the report. "User_role" is also a column value?

    The simplest option is to modify the column attribute display as for the Standard report columnID column and conditionally generate the link in the report query:

    select
    ...
  , case
      when user_role = role_this_line_item
      then
        'where DATA_ENTRY is the 'data entry page' target number or alias of the page.

  • Basic conditional script based on the number of lines in a text layer?

    Just received help here to write a conditional script by using the font size of a text layer. Thank you all for this.

    The next hurdle is a conditional script using the number of lines in a text layer in the differential. Far as I can tell it not the layer details which specify the number of lines. Just '\r' for a return in the idTxt descriptor. Nothing seems to stand for a soft return as far as I can tell. I'll probably have to be able to count the lines with soft and hard returns.

    Any thoughts?

    I was playing around with this a bit and here is a small script to determine the number of rows. This is based on the self in the head, that I calculated to environ.108 times the size of the font.

    #target photoshop
app.preferences.rulerUnits = Units.POINTS;
var doc = activeDocument
var tL = doc.activeLayer
var h = tL.bounds[3]-tL.bounds[1]
var per = ((h/5)-(tL.textItem.size))/tL.textItem.size
var num = h/(tL.textItem.size *1.108)

alert(Math.round( num))

  • Avoiding the TRUNC as a condition of setting for the date of transaction

    I've never noticed this before, but tonight I have tested a query and made a trunc (mmt.transaction_date) between April 1, 2012"and 20 April 2012 ' in TOAD and I noticed it was taking a long time to run.

    If I remove the trunk and use mmt.transaction_date > = 1 April 2012 ' and mmt.transaction_date < 21 April 2012 "the query ran a lot faster and the explain command plan was also much better."

    Then I read that this truncing the date of the operation will be used the index on this field in the table when searching it.

    But if I change the setting so that the condition is set to add - it to the parameter, it does not work and maybe someone can help you. This is probably an obvious solution that I just think not.

    I created the discoverer as conditions:
    The operation date > =: Start Date of Transaction
    and
    The operation date < = (: Start Date of Transaction + 1).

    But I get an error "one of the arguments of the function has an invalid data type.

    Or maybe I'm wasting my time trying to avoid using the TRUNK on the date of the transaction?

    Kind regards
    Jerry

    Hello

    You should be OK with the condition:

    The transaction date > =: Start Date of Transaction and the Transaction Date< to_date(:transaction="" start="" date)="" +="">
