Need help with the query to get the County

Hello

Oracle 10 g 2 10.2.0.3 - 64 bit

I want back the number of accounts with two different types of funds (say A and B). Some accounts hold only one of the two funds, and some support both. I want to get the counts like this:

  • account held funds - has only
  • accounts holding funds-B only
  • accounts holding the Fund-A and B funds

Here is what I started with but need assistance to meet the requirement above:

select 
count(distinct acct.bkoff_acct_no ) accounts_holding_fund_A
from xe_account acct,
        xec_tal_investment_mandate iman,
        xec_tal_asset_allocation alloc,
        xe_benchmark bmark,
        xe_benchmark_usage bu,
        xe_object_description xod,
        xec_asset_class cls
where iman.mandate_status_cd='A'
and cls.asset_class_cd = alloc.asset_class_cd
and iman.mandate_id = alloc.mandate_id
and acct.account_id = iman.object_id
and iman.object_type_cd = 'ACCT'
and iman.mandate_id = xod.object_id
and xod.field_nm='XEC_TAL_INVESTMENT_MANDATE.COMMENT_TXT'
and xod.language_cd = 'E'
and acct.acct_status_cd = 'O'
and bu.object_type_cd(+) = 'TMAA'
and bu.object_id(+) = alloc.asset_allocation_id
and bmark.benchmark_id(+) = bu.benchmark_id
and alloc.resp_txt like '%fund-A%'


And suppose that the Fund-B has resp_txt like ' % of Fund-B»

Please suggest.

Hello

Here is another way, it is easier to adapt to different jobs and different numbers of jobs:

WITH got_distinct_jobs AS

(

SELECT DISTINCT deptno, job

FROM scott.emp

WHERE job IN ("ANALYST", "CLERKS") - or what

)

got_job_list AS

(

SELECT LISTAGG (job, ",") THE Group (ORDER BY work) AS job_list

OF got_distinct_jobs

GROUP BY deptno

)

SELECT job_list

COUNT (*) AS num_departments

OF got_job_list

GROUP BY job_list

;

This shows all the combinations of the jobs listed in the WHERE clause of got_distinct_jobs.  You don't need to change anything else in the query.  There may be any number of jobs.

Output:

JOB_LIST NUM_DEPARTMENTS

------------------------------ ---------------

CLERK                                        2

ANALYST, CLERK 1

  • Hello need help with the opacity mask.

    Hello need help with the opacity mask. I hope someone out there can help

    I inherited a logo that appears to use a Logo of OM has a shape with a grad. This grad at first sight is not used in the Grad scheme and there is not editable.  Looking at the transparency palette I find an OM (pic1) output option. If I choose what the grad on separates it from the page of the form, that is from there I can change/remove as required (Note2).

    However, sometimes (he did no change), I'll be back to the same original form and output option is grayed out and is no longer available. Or I go to the similar shape that has the same treatment and I can't go out OM (pic3)

    The only difference is the thumbnail in the transparency palette, which is strong in pic1 and rated on pic3. What Miss me?    I'm not clear what the advantage is simply OM using the Grad palette to apply a grad in my form, but until I can get rid of OM who is there, I can't comfortably apply to the grad I want.

    The white gradient LHS I have no problem with. I choose fortunately only and each time get the possibility of release of OM.

    Screen Shot 2015-08-06 at 12.26.48.pngScreen Shot 2015-08-06 at 12.00.10.pngScreen Shot 2015-08-06 at 12.01.16.png

    The other thing weird. When I select the white gradient. Sometimes, the exit option is in the palette without going through the drop-down list (Fig 4).

    Other times seems not that OM has already been applied, because the palette gives me the ability to mask rather than liberation (5 photos). Until I go to the drop down and then I find Release is an option after all.

    What is the difference here?   Not much of a problem, because either way I can release OM to be able to change the grad.

    The file is passed through several hands and play anywhere to try to resolve issues, and many stops and save slot, so something along the line was of course done a logo and not the other because of the difference, but I can't for the life of me see what that.

    Dave,

    I've (mis) understanding the issues, you can account for the box to the right in the main palette transparency (called thumbnail) here.

    Illustrator help | Transparency and blending modes

    represents the masking objects.

    Some of your screenshots show no object mask, so it only is not really a mask even if do the opacity mask has been clicked and there seems to be one in the layers palette, wherever you look.

    I think that it is perhaps the issue.

  • I need help with the control of two .swf in third.

    Hi, thanks for reading!

    I need help with the control of two .swf in third.

    I have a problem when I need to use a .swf in a digital signage solution, but were advised by the Legal Department, it cannot be changed in any way, I can not also have the source file blah blah blah. I pulled the .swfs on their site and I decompiled to see what I was up against.

    The main SWF that I need control is HCIC.swf and the problem is that it starts with a preloader, which, after the loading stops on a framework that requires user input to (button) on a play button, until the film will proceed and replay.

    What I've done so far is to create a SWF container, HCIC_container.swf, which will serve as a target for the HCIC.swf and I would like to send actionscript in the file, I am not allowed to edit.

    I managed to get done with help from someone on another forum. It is my hope that the following script just start HCIC.swf a framework after the preloader and button play and just play through.

    var container: MovieClip = createEmptyMovieClip ("container", getNextHighestDepth());
    var mcLoader:MovieClipLoader = new MovieClipLoader();
    mcLoader.addListener (this);
    mcLoader.loadClip ("MCIC.swf", container);

    function onLoadInit(mc:MovieClip) {}
    mc.gotoAndPlay (14);
    }

    But unfortunately it does not solve my problem. Because there is a media - controller.swf, which is charged by HCIC.swf who has orders, including the play button to start HCIC.swf.

    Here is a link to a .zip with all 3 files .swf file and all 3 .fla files.

    http://www.axiscc.com/temp/HCIC.zip

    What I have to do is to automatically start the HCIC.swf file, bypassing the pre-loader and play button without having to edit it or in the media - controller.swf in any case. Thus, all scripts must be done in HCIC_container.swf.

    I know it is confusing and it is difficult to explain, but if you look at the files it must make sense.

    ActionScripting is far from my point hard, so I'm definitely over my head here.

    Thanks for your help.

    Got my solution on another forum.

    The link below is a guige to install a video card in your Pc.  In particular, it seems that you will have to perhaps specify the location of the new card in the bios and save this change before you install the new card - see step 4 in the guide on the link below.  If your new card fits into the PCI Express x 16 slot, you will need to define PCI Express in the bios and save the changes.

    Do not use the feature distribute the form. Instead of this, just put up a button "submit" and configure it to send email using any email address you want.

  • Making the ear of corn and need help with the ball.

    I do some corn on the COB for an illustration and I need help with the texture of the ball. I've been slowly making progress with gradient for kernels mesh, but I can't seem to recreate the look of the ball at all. I tried to recreate it in a rectangle by using the option in the menu object (1 row, 50 columns) gradient mesh and I'm trying with the fusion in object mode, but not lucky yet. Can someone help to put me on the right track to make the texture:

    I've been slowly making progress with gradient for kernels mesh, but I can't seem to recreate the look of the ball at all.

    Tank,

    You have published three images stylistically very different. The first is photographic and call probably (but not necessarily) for graduates of mesh. The other two are graphical treatments (and frankly, they're both rather flat; lack of depth).

    Illustration style extends the range of cartoonish in sketchy photo-realism and all the rest. The problem is you didn't show your own attempt so that anyone can have an idea of what you're trying to achieve the stylistic point of view.

    I just need to put in place so that the final step does not appear the whole box. The problem now is trying to make the style of the good brush to reproduce the effect...

    You seem to think you have to build a kind of linear construction and then find a way to reshape the shape of each part of the leaf. Yes, you pouvez approach it this way, but Illustrator users has often tend to be what aunt Molly would call "too clever by half."

    Not everything must be something semi intelligent auto or complex and tedious consruct involving brushes, envelopes, masks, etc, etc. Much can be accomplished by thinking that he just thanks to measure you draw directly economic paths and constructions, which take no more time (often less) and result in very tidy, simple files. Again, a lot depends on what you are trying to achieve the stylistic point of view. But here's an example that only took a few minutes to draw:

    If the above consists of:

    Three roads closed, 8 points each, with ordinary linear degrees

    Three mixtures of open path with three anchor points for each key path

    Six paths closed for shadows / highlights, with 19 points in total

    Mixtures being directly from the paths drawn comic forms, the spacing of the veins 'automatically' and intuitively follows the width from point of view of the worksheet.

    Rather than to build a boilerplate brush, colouring and the weight of each of the three main paths of the vein mixtures can be set individually at any time, simply directly by selecting the key path.

    Insert into user_tab_col_test (table_name, column_name, data_type) values ('table1', 'column1', 'varchar2')
    Insert into user_tab_col_test (table_name, column_name, data_type) values ('Column2', 'table1', 'varchar2')
    Insert into user_tab_col_test (table_name, column_name, data_type) values ("Column3", 'table1', 'varchar2')
    Insert into user_tab_col_test (table_name, column_name, data_type) values ('column4', 'table1', 'varchar2')
    Insert into user_tab_col_test (table_name, column_name, data_type) values ("column1", "table2", 'varchar2')
    Insert into user_tab_col_test (table_name, column_name, data_type) values ('table2', 'column2', 'varchar2')
    Insert into user_tab_col_test (table_name, column_name, data_type) values ('table2', "Column3", 'varchar2')
    Insert into user_tab_col_test (table_name, column_name, data_type) values ('table2', 'column4', 'varchar2')
    Commit;

    Create table all_cons_columns_test (varchar2 (30) from table_name, column_name varchar2 (30), constraint_name varchar2 (30))

    Insert into all_cons_columns_test (table_name, column_name, constraint_name) values ("table1", "column1", "primary")
    Insert into all_cons_columns_test (table_name, column_name, constraint_name) values ("table1", "column1", "secondary")
    Commit;

    This is my query and the current result:

    Select u.table_name, u.column_name, c.constraint_name
    Of user_tab_col_test u
    Outer join all_cons_columns_test c left
    On (u.table_name = c.table_name
    AND U.COLUMN_NAME = C.COLUMN_NAME
    AND C.CONSTRAINT_NAME IN ('main'))
    order of U.table_name, U.COLUMN_NAME;

    TABLE_NAME COLUMN_NAME, CONSTRAINT_NAME
    ------------------ --------------------- ----------------------------
    Table1 primary Column1
    Table1 Column2
    Table 1 Column3
    Table2 Column1
    Table2 Column2


    Three questions:
    (1) I don't want to return results where table_name = "table1". I can't get this to work.
    (2) is my proper request and this is the best way to return my desired results? For example, I want all of the columns of user_tab_col_test and I want to only display the constraint_name from all_cons_columns_test argument if the argument constraint_name = 'primary '.
    (3) will be the synatx be the same if I need to join a third table to all_cons_columns_test?

    Any advice/suggestions are appreciated-
    John

    Thanks for posting the CREATE TABLE and INSERT.
    It is more useful if you post the code that can be run without modification. You did not semicolons after INSERTION instructions.

    Three questions:
    (1) I don't want to return results where table_name = "table1". I can't get this to work.

    What have you tried? Post your best attempt.
    Here's one way:

    SELECT    u.table_name
    ,        u.column_name
    ,        c.constraint_name
    FROM             user_tab_col_test      u
    LEFT OUTER JOIN  all_cons_columns_test  c
                            ON    u.table_name     = c.table_name
                   AND   u.column_name     = c.column_name
                   AND   c.constraint_name IN ('primary')
    WHERE       u.table_name     = 'table1'          --  *****  NEW  *****
    ORDER BY  u.table_name
    ,            u.column_name
    ;
    

    You would not put this condition in the clause; who controls what is considered as a match between the tables, and "u LEFT OUTER JOIN c" means show all lines of u, even if they do not have a match in the c.

    (2) is my proper request and this is the best way to return my desired results? For example, I want all of the columns of user_tab_col_test and I want to only display the constraint_name from all_cons_columns_test argument if the argument constraint_name = 'primary '.

    Basically, this application is very well.
    It displays all the columns of user_tab_col_test; missing data_type. Just add u.data_type to the SELECT clause, or change the SELECT clause

    SELECT    u.*
    ,         c.constraint_name
    

    (3) will be the synatx be the same if I need to join a third table to all_cons_columns_test?

    Do you mean "" * add * one-third * column * to all_cons_columns_test '? "
    It depends on what results you want. Post new CREATE TABLE and INSERT and instructions the results you want new data.
    Most likely, the basic structure of what you've written will remain exactly the same.

  • Need help with the error of connection Internet "Reset local connection adapter".

    Original title: Need help with Internet connection.

    Hi, sometimes when I go to my office (HP 2009 m) I get a message that I am not connected to the internet (although I have no problem with the connection on my IPad).  When I click on solve internet connection Windows Network Diagnostics freezes when it gets to solve problems "the local connection adapter reset."   I have to turn off my computer by unplugging and then it works normally when she returns to the top. (Sorry if my explanation is difficult to decipher, I'm not very tech savvy) This could be the cause and how to fix it?  Thanks in advance.

    Well, I expected more of a response, but I'll wing it from here: your cable goes into a modem.  This modem can be a wireless modem/router, or simply a modem cable to your computer.

    Connection problem you might start by connecting the cable into the modem.  Ensure that it is well defined.  If everything looks good, then it is possible that there is a decline in cable service before he gets to the modem.  For example, the interface side of the House can be affected by a bad connection, for example water intrusion, or poor soil.  So you may want to check into that.  Then, there is always the possibility that your cable provider has lost his momentaily of transmission, and that the modem needs to be reset.  If this happens often, you must contact the cable provider.

    Modem, your computer can be connected by cable, so you will need to check how firmly the connection is.  Then, there is always the possibility that the modem is wrong.

    But if your connection is through a wireless modem/router, your connection may have lost because of a bad signal.  Once more..., the modem/router could go wrong.

    Edit has added:

    Looking back on what you said about the Ipad, I feel that you have a wireless modem/router.  It is possible that your connection to the desktop must be after you have used the Ipad.  For example, you may need to right-click on the monitor icon in the Systray to your desktop and open your network sharing Center.  Even if you can say that you are connected to the Internet, you may not.  Then... just ... simplement cliquer click on 'connect or disconnect', then find your network connection appropriate, right click on that and select disconnect, then immediately right-click the same but select Connect.


    Will be a new connection to the Internet.
