Select the first choice to join

Hello

I have a problem in the application.

Requirement:

the user has options to select the brand and the user interface element.

mark and point are from two different tables.

Neither brand nor element is mandatory.

ELEMENTS
item_idNom_elementitem_brandbrand_id
1bikeHonda11
1bikeTVS12
1bikeBailey13
2carHonda11
2carToyota14
3carSuzuki15
1bikeSuzuki15

BRAND
brand_idbrand_name
11Honda
12TVS
13Bailey
14Toyota
15

Suzuki

MY_TABLE
IDbrand_iditem_id
21(null)(null)
2211(null)
23(null)1
24111

SQL

Select my.id, my.brand_id, b.brand_name, my.item_id, i.item_name

from my_table my, mark b, points i

where my.brand_id = b.brand_id (+)

and

My.item_id = i.item_id (+)

order of my.id;

I want to display the details of my table with id brand and name brand... and item id, item name...

but the sql above gives double for the name of the item while that no brand is selected... and also a few duplicates while giving the id brand and point.

If anyone can help with the query.

This issue will be triggered in the sql forum.

  • Select the first 20 days of the month for a given date

    Hi gurus,

    Please let me know to select the first 20 dates for a date supplied by using a parameter.

    For ex -.

    Suppose I provided a date by using a parameter - January 13, 2012

    The query should return me - 01-Jan-2012, January 2, 2012... January 20, 2012

    or if I get home on 23 March 2012

    The query should return me - 01-Mar-2012, March 2, 2012... 20 March 2012

    Thanks in advance.

    Hello

    Here's one way:

    VARIABLE  target_date     VARCHAR2 (11)
    EXEC     :target_date := '13-Jan-2012';
    
    SELECT      TO_DATE ( SUBSTR (:target_date, 4)
                , 'Mon-YYYY'
               ) + LEVEL - 1     AS a_date
    FROM     dual
    CONNECT BY     LEVEL     <= 20
    ;
    

    Note that this does not take account the part of: target_date that represents the day of the month. When you use TO_DATE without giving a date of the month, it defaults to the 1st of the month.

  • It is possible to select more than one layer by selecting the first and the last layers?

    I frequently get Illustrator files which are individual objects such as the paths on separate layers that can be grouped together to make the shorter layers. I find that I have to change click on each individual layer to select it to finally bring together them. Sometimes, I have 25 or so layers that I need to select. Is there a way to select the first and the last layer in the layers palette and have Illustrator select all the layers in the meantime?

    Don't know about the selection of layers of first/last, but to select several consecutive layers in the layers palette...

    Option-click on (Mac) on a layer to select it and, with the option always pressed key, drag to the bottom of the list - DO NOT slip on as logical target icons you like.  When you drag to the bottom of the list of layers, the icons of the target will become selected.

    Shift + Option-click allows you to ignore the layers and continue to select consecutive additional layers on the bottom of the palette.

    Note: Drag slowly or some layers would not choose.

    Strange, I know.  It took me years to come across this.

  • Click event does not work for the first choice of object field index

    Hello

                    });
    //
                }
    

    Please help me...

    Here it happens little differently. I explain the requirement properly. Suppose that the I am A screen where I have the ObjectChoiceField. I added a choice of X. Now, when I am pressing on the field of choice and selection, it must pass on the screen (B) but that the choice of the field is choice (X) only one, it is not mobile. Now if, after the addition of the choice of two X and Y, if I select go, it's going to screen B. But when again, the field of choice has 2 options X and Y with X as the default selection. There is therefore no chance for me to choose the X.

    Therefore, I have added a Select called default choice. Now, if X is added, field of choice is the choice of towing display: Select and X. And while choosing X, it moves on the screen B.

    Hopefully now, it is good for understanding.

    And can help me please to this: http://supportforums.blackberry.com/t5/Java-Development/How-to-on-the-Camera-Flash-for-a-long-time-l...

  • How can I select the first date (at least) and the corresponding date of two different tables source?

    I have 2 tables, INVOICE and INVOICE_REFNUM similar to below. I'm writing a query that withdrawing the first date (less) for a single record remaining the two tables. Each table records the receipt of invoices, but according to the source of the received invoice some may reside in INVOICE_REFNUM and others the INVOICE table. I also use DECODE on the topic of INVOICE_SOURCE, when the date less is taken from the INVOICE table that contains that field, so if the date is in the field INVOICE_REFNUM DECODE is not necessary. Example:

    INVOICE (table)

    INVOICE_GID INVOICE_SOURCE INSERT_DATE

    ABC. AVRT123 I HAVE 11/03/2012-15:49:32

    ABC. CNWY234 G 12/03/2012 14:07:30

    ABC. UPGF678 M 15/03/2012 20:21:54

    INVOICE_REFNUM (table)

    INVOICE_GID INVOICE_REFNUM_QUAL INVOICE_REFNUM_VALUE INSERT_DATE

    ABC. AVRT123 SOURCE ACS 11/03/2012 14:49:32

    ABC. CNWY234 SOURCE CSA 12/03/2012 13:07:30

    ABC. UPGF678 SOURCE ACS 15/03/2012 21:21:54

    My decode statement is: DECODE ("INVOICE_SOURCE, 'I', 'IDE', 'G', ' Auto-Pay", ', 'Manual')

    If I were to write a query on these two tables, the output will resemble the following:

    INVOICE_GID INVOICE_SOURCE INSERT_DATE

    ABC. AVRT123 ACS 11/03/2012 14:49:32

    ABC. CNWY234 ACS 12/03/2012 13:07:30

    ABC. UPGF678 Manual 15/03/2012 20:21:54

    I worked on it for 2 days, and I was able to pull a date by using the following SQL code, but cannot determine how to extract the corresponding source:

    SELECT THE LEAST (GLOGOWNER. INVOICE_REFNUM. INSERT_DATE, GLOGOWNER. THE INVOICE. INSERT_DATE) AS 'DATE OF THE INVOICE.

    GLOGOWNER. THE INVOICE. INVOICE_GID,

    DECODE (GLOGOWNER. THE INVOICE. INVOICE_SOURCE, 'I', 'IDE', 'G', 'Auto-Pay', ', 'Manual').

    GLOGOWNER. INVOICE_REFNUM. INVOICE_REFNUM_VALUE

    OF GLOGOWNER. INVOICE

    LEFT JOIN GLOGOWNER. INVOICE_REFNUM

    ON GLOGOWNER. THE INVOICE. INVOICE_GID = GLOGOWNER. INVOICE_REFNUM. INVOICE_GID

    WHERE GLOGOWNER. INVOICE_REFNUM. INVOICE_REFNUM_VALUE = "ACS."

    AND GLOGOWNER. INVOICE_REFNUM. INVOICE_REFNUM_QUAL_GID = 'SOURCE '.

    AND GLOGOWNER. THE INVOICE. INVOICE_TYPE = 'I '.

    ORDER OF GLOGOWNER. THE INVOICE. INVOICE_GID

    Any help is greatly appreciated!

    Hello

    Is that what you want?

    SELECT i.invoice_gid

    CASE

    WHEN ir.insert_date<= i.insert_date ="" then ="">

    WHEN i.invoice_souce = 'I' and THEN 'EDI '.

    WHEN i.invoice_souce = 'G' THEN 'debit '.

    WHEN i.invoice_souce = am' THEN 'manual '.

    END AS invoice_source

    , The LEAST (i.insert_date, ir.insert_date) AS insert_date

    I have the Bill OF

    JOIN invoice_refnum ON i.invoice_gid = ir.invoice_gid ir

    WHERE ir.invoice_refnum_value = 'ACS '.

    AND ir.invoice_refnum_qual_gid = 'SOURCE '.

    AND i.invoice_type = 'I '.

    ORDER BY i.invoice_gid

    ;

    There is no reason to do an outer join if you only want the lines with specific values anyway.

    What happens if the 2 tables have exactly the same invoice_date?  The query above takes the invoice_source of invoice_refnum in this case, but that can easily be changed.

    Or the other of the insert_dates can be NULL?

    I hope that answers your question.

    Otherwise, thank you post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also after the results you want from these data (otherwise what you have already posted).

    Explain, using specific examples, how you get these results from these data.

    Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  • Close the startpoint and endpoint without selecting the first

    Hi guys,.

    I'm working on an image of polygon which means I have created hundreds and hundreds of small triangles with the path tool.

    Now, I have wondered if it is possible to create two lines of the triangle in hand and close the last third line of triangles in shortcut.

    There may be a shortcut (or almost) to connect the beginning and the end of a path? I know I can do it by clicking on cmd + J, but I first select the points which is more work than simply connecting them to the hand. It would be perfect if there's any way to close it without selecting it first, so that I can do an 'action' out of it with a shortcut!

    Any ideas?

  • How to select the first item in an array in a loop FOR

    Hello.

    I use Labview 8.5

    In my application, I have a loop 'for' where I read some values from a device. (strings and digital)

    As you know Labview 'stores' values up to what the loop 'for' is completed, and then they come out in a table.

    Ok.

    I want to just use the first element for strings and digital and then do something with it, like to compare (for digital)

    For strings, I used successfully 'Split 1 D Array' and choose 'everything first subarray'. Good.

    Now for digital that works too, but the result is an element, array type too. I need to be digital (decimal) is not no table type, because I need to compare (greater than 0). Then use a case...

    So, table of an element in a digital decimal? Or the table at the first decimal element. How?

    I tried also with the subset of the table. Even think. Labview won't let me compare a table 1 d with 0. It makes sense, but how to convert, to have the first decimal element?

    Try to use the 'Index Array' function. If you do not connect to the terminal of the index value, it will return the first elelemnt in the table. If wire you an index, it will return the value specified.

  • When I select the first line number I get a little gray box pop up. This looks like a changer of glyph. How to disable this option?

    Above is the example. I don't know what happened (my fault or updated) to activate it, but I can't find anything to delete it. It's not useful because it does not work for numbers later in the line, only the first issue.

    You can disable this option in advanced Type preferences, the bottom section.

  • Select the first value in the list of values when running in poplist

    Hello
    IM using forms 6i. I filled the poplist by request. But what I need, I want to choose the first value in the list of values when running...

    That is to say, during execution, the poplist should have chosen its first value in the list of values.

    What to do...

    Concerning
    Sery

    WHEN CREATING a RECORD of the block of the list item or after the filling of the list item, you can write

    : my_list_item: = GET_GROUP_CHAR_CELL ('my_list_item', 1); / * If the data type of the item in your list is character.*.

    Here, instead of 1, you can give any clue... 1: value to the first list item position
