Left join with three-table join query
I am trying to create a query that left me speechless. Most of the query is simple enough, but I have a problem I do not know how to solve.
Background:
We have stock stored in i_action.
We have the attributes available for each type of action. The attributes available for each action are described in shared_action_attribute. Each type of action can have three attributes or none at all.
We have the values stored for the attributes in i_attribute_value.
An example says:
We have a transfer action (action_code B4). The action of B4 entry into i_action records the fact that the transfer took place and the date at which he spoke. The attributes available for a transfer action are the function code receiver, the receiving unit number and the reason of transfer code. These types of attributes available and their order are stored in shared_action_attribute. The actual values of the attributes for a specific action of transfer are stored in i_attribute_value.
Now i_action and i_attribute_value can be connected directly in action_seq in i_action and ia_action_seq in i_attribute_value. A left join on these two tables provides results for all actions (including actions that have no attributes) and assign values (see Query 1 below).
There are two questions. First of all, I want only the first two attributes. To specify the attributes of the first two, I also i_attribute_value a link to shared_action_attribute (which is where the order is stored). I can build a simple query (without the left join) which connects the three tables, but then shares without attributes would be excluded from my result (see Query 2 below).
The second problem is that I'd actually a row returned for each action with first_attribute and second_attribute in the form of columns instead of two lines.
The final query will be used to create a materialized view.
Here are the tables and examples of what is stored in the:

It's my current query as well as its results. Most are select simple but only one column is filled using the function analytic last_value (thank you guys). The last column in the view sub stores the value of the attribute. What I want is to replace this single column with two columns named first_attribute and second_attribute and eliminate all other attributes.

Thank you very much!Hello
You can use an alias for column (such as staff_seq) in the ORDER BY. Unfortunately, it's the only place where you can use it in the same query, where it was defined.
You can use it anywhere in the super-requetes, however, so you can still work around this problem in assigning the aliases in a subquery and GROUP BY (or other) in a Super query, like this:WITH ungrouped_data AS ( SELECT ia.action_seq, ia.action_date, ia.action_code, NVL (LAST_VALUE (CASE WHEN ia.action_code = 'G1' AND sactatt_sat_type = 'SS' THEN VALUE WHEN ia.action_code IN ('A0', 'A1') THEN '67089' END IGNORE NULLS ) OVER (PARTITION BY ia.ici_charge_inquiry_seq ORDER BY ia.action_date, ia.action_seq), '67089' )staff_seq, (CASE WHEN display_order = '1' THEN VALUE END) first_attribute, (CASE WHEN display_order = '2' THEN VALUE END) second_attribute FROM i_action ia LEFT JOIN i_attribute_value iav ON iav.ia_action_seq = ia.action_seq LEFT JOIN shared_action_attribute ON sactatt_sact_code = sact_code AND sactatt_sat_type = sat_type WHERE ia.deleted = 'A' ) SELECT action_seq , action_date , action_code , staff_seq , MIN (first_attribute) AS first_attribute , MIN (second_attribute) AS second_attribute FROM ungrouped_data GROUP BY action_seq , action_date , action_code , staff_seq ;There are other alternatives for special cases, but none of them work in this particular case.

I use Oracle 10 g. I am familiar with free joins, but that alone will not do the job. Thank you!Hello

A self-join 2-way would work for lines have no parent, or lines which are directly related to their final ancestor (such as the oid = 4), but not for what anyone further.
A 3-way self-join would work to a level more away from the last row, but no more. That would be enough with the small set of sample data that you posted, but it won't work if you have added a new rank parent_id = 10.
An N - way self-join would work for up to N + 1 levels, but no more.You need something that can go to any number of levels, such as CONNECT BY:

On sober reflection, I think that a request from top down, as one below, would be more effective than a motion up and down, like the one above:
SELECT oid , CONNECT_BY_ROOT parent_oid AS final_parent FROM a START WITH parent_oid = oid CONNECT BY parent_oid = PRIOR oid AND oid != PRIOR oid ; -
Hello
I'm having a problem with the left join query, when I join table a two table based on column task1 I get duplicate in table1.task1, table1.price.
Table1. Task1 Table1. Price table2. Task1 table2. Resource table2. Price 001 100 001 A 50 001 100 001 B 250 How can I make a request to get a result as below.
Table1. Task1 Table1. Price table2.Task2 table2. Resource table2. Price 001 100 001 A 50 001 B 250 Thank you.
Note that your query uses an inner join. Your original question mentioned a join left, generally interpreted as meaning a left OUTER join.
Anyway, according to Frank, you can use the BREAK command in SQL * Plus for the goal sought through formatting. You can also use an analytical function as Roger suggests. I think ROW_NUMBER() might do the trick, but we must be clear about the criteria for partitioning and ordering the results, for example
WITH table1 AS ( SELECT '001' AS task1 , 100 AS price FROM dual ), table2 AS ( SELECT '001' AS task1 , 'A' AS resources , 50 AS price FROM dual UNION ALL SELECT '001' AS task1 , 'B' AS resources , 250 AS price FROM dual ) SELECT DECODE(ROW_NUMBER() OVER (PARTITION BY t1.task1, t1.price ORDER BY t2.resources, t2.price),1,t1.task1) AS task1_alt , DECODE(ROW_NUMBER() OVER (PARTITION BY t1.task1, t1.price ORDER BY t2.resources, t2.price),1,t1.price) AS price_alt , t2.task1 AS task_with_resource , t2.resources , t2.price FROM table1 t1 INNER JOIN table2 t2 ON t1.task1 = t2.task1 ORDER BY t1.task1, t1.price, t2.resources, t2.price; -
Hey everybody!
I have some difficulty in trying to create a SQL query.
I have the following tables:
-Table Products: Product list
CREATE TABLE (PRODUCTS)
PRODUCT_ID INTEGER NOT NULL,
KEY ("PRODUCT_ID") PRIMARY CONSTRAINT 'PK_PRODUCTS '.
);
-Orders table: Decreed this product
CREATE TABLE ORDERS)
ORDER_ID INTEGER NOT NULL,
PRODUCT_ID INTEGER NOT NULL, / * FK PRODUCTS (PRODUCT_ID) * /.
KEY ("ID_PEDIDO") PRIMARY CONSTRAINT 'PK_ORDERS '.
);
-Orders_Approval table: register when an order is approved
CREATE TABLE ORDERS_APPROVAL)
ORDER_ID INTEGER NOT NULL, / * FK ORDERS (ORDER_ID) * /.
APPROVAL_DATE DATE NOT NULL,
USER_ID INTEGER,
KEY("ORDER_ID","APPROVAL_DATE") PRIMARY CONSTRAINT 'PK_ORDERS_APPROVAL '.
);
-Table Orders_ApprovalData: Register more details on the amenities of the order
CREATE TABLE ORDERS_APPROVAL_DETAILS)
APPROVALDET_ID INTEGER NOT NULL,
ORDER_ID INTEGER NOT NULL, / * FK ORDERS_APPROVAL (ORDER_ID) * /.
APPROVAL_DATE DATE NOT NULL, / * FK ORDERS_APPROVAL (APPROVAL_DATE) * /.
KEY ("APPROVALDET_ID") PRIMARY CONSTRAINT 'PK_ORDERS_APPROVAL_DETAILS '.
);
The thing is that an order may OU cannot be approved. Thus, there could be no record of an order in ORDERS_APPROVAL.
In addition, an order can have more than one approval.

I need to create a query that returns the data in all tables, but for orders with more than one certification,
the query must return only the last record. It is also necessary return orders that have not yet been approved.
My first query looked like this:
SELECT
*
Of
ORD IN ORDERS,
PRODUCT PROD,
ORDERS_APPROVAL ORDAPPROV,
ORDERS_APPROVAL_DETAILS ORDAPPDET
WHERE
PROD. PRODUCT_ID = DSB. PRODUCT_ID
AND ORDAPPROV. ORDER_ID (+) IS DSB. ORDER_ID
AND ORDAPPDET. ORDER_ID (+) IS ORDAPPROV. ORDER_ID
AND ORDAPPDET. DATA_APPROVAL_DATE (+) IS ORDAPPROV. APPROVAL_DATE
PS: I use the Oracle 8 syntax because it's the server I'll use. In addition, I can't change the design of database.
This query returns the data in table all. Because I used LEFT JOIN "(+)" to join the table orders_approval with the orders table, I am able to see even the orders with no approval.
But this way, I see also two approvals for order 27 (with the data above, this order was approved twice). I need to reach my paintings in the last approval for each order is but should be a left join so I can see the orders with no approval.
I tried this way:
SELECT
*
Of
ORD IN ORDERS,
PRODUCT PROD,
ORDERS_APPROVAL ORDAPPROV,
ORDERS_APPROVAL_DETAILS ORDAPPDET
WHERE
PROD. PRODUCT_ID = DSB. PRODUCT_ID
AND ORDAPPROV. ORDER_ID (+) IS DSB. ORDER_ID
--Also added the line below
AND ORDAPPROV. APPROVAL_DATE = (SELECT MAX (APPROVAL_DATE) OF ORDERS_APPROVAL WHERE THE ORDER_ID = ORDAPPROV. ORDER_ID)
AND ORDAPPDET. ORDER_ID (+) IS ORDAPPROV. ORDER_ID
AND ORDAPPDET. DATA_APPROVAL_DATE (+) IS ORDAPPROV. APPROVAL_DATE
But in this way, as I am specifying I want only records with approval equal to date at the latest for each order, I do not see the order without approval.
I tried again, with a left join like this:
SELECT
*
Of
ORD IN ORDERS,
PRODUCT PROD,
ORDERS_APPROVAL ORDAPPROV,
ORDERS_APPROVAL_DETAILS ORDAPPDET
WHERE
PROD. PRODUCT_ID = DSB. PRODUCT_ID
AND ORDAPPROV. ORDER_ID (+) IS DSB. ORDER_ID
--Also added the line below
AND ORDAPPROV. APPROVAL_DATE (+) = (SELECT MAX (APPROVAL_DATE) OF ORDERS_APPROVAL WHERE THE ORDER_ID = ORDAPPROV. ORDER_ID)
AND ORDAPPDET. ORDER_ID (+) IS ORDAPPROV. ORDER_ID
AND ORDAPPDET. DATA_APPROVAL_DATE (+) IS ORDAPPROV. APPROVAL_DATE
But I get a syntax error. Oracle said that it is not possible to do a join with a subquery.
If anyone knows how I can bring all this data?
Thanks in advance.

Welcome to the forum!
A scalar, such as subquery
(SELECT MAX(APPROVAL_DATE) FROM ORDERS_APPROVAL WHERE ORDER_ID=ORDAPPROV.ORDER_ID)is allowed in a WHERE clause, but not as a condition of outer join, as you discovered.
A workaround is the query expression so that it is not part of the outer join condition, which invlove in May (as in this case), adding another subquery. In the following query, the table of orders_approval in your original OF Division is replaced with online view, which uses the exact same scalar subquery in the WHERE clause. The online display will only contain one line per order_id (assuming that there is no link with for last approval_date).
SELECT * FROM orders ord, products prod, ( -- Begin in-line view ORDAPPROV of last approval_date only SELECT * -- or list the columns needed in main query FROM orders_approval oa WHERE approval_date = ( SELECT MAX (approval_date) FROM orders_approval WHERE order_id = oa.order_id ) ) ordapprov, orders_approval_details ordappdet WHERE prod.product_id = ord.product_id AND ordapprov.order_id (+) = ord.order_id AND ordappdet.order_id (+) = ordapprov.order_id AND ordappdet.approval_date (+) = ordapprov.approval_date ;Thank you for including CREATE TBAL statements; It is very useful.
You want to be even more useful in the future? Post INSERT statements for the sample data. That will make it easier for people to respond and easier for them to test their ideas. -
Having trouble getting my head around that, so would appreciate any help.
I run the query below, which includes a join. If I run this query through Navicat (for those who don't know, a MySQL GUI) - I get the expected result.
I also have a similar query running on the site elsewhere with success, so I am struggling to understand why it does not work.
The request is;
< name cfquery = "getwatched" datasource = "#datasource #" >
SELECT r.retailer_name, r.id, r.shortname, d.id, d.merchant_id, d.user_id, d.e_updates
OF cc_watchlists d
LEFT JOIN merchant r
ON d.merchant_id = r.id
WHERE d.user_id = #SESSION. Auth.ID #.
ORDER BY r.retailer_name ASC

and the exit;

< TD > < a href = "page.cfm? for = #shortname #" > #retailer_name # < /a > < /dt >
< / cfoutput >
Error States;
coldfusion.runtime.UndefinedVariableException: Variable SHORTNAME is undefined.
I would appreciate any help!Make a
the entire query just before the line which is the slightest error, and
Make sure that it contains what you think that it contains.--

That IS NULL is done by replacing the NOT EXISTS operator with an outer join?
DB version: 10 gr 2
An example of searchoracle.target.com
The query that contains a NOT EXISTS operator
is replaced by an equivalent outer join querySELECT M.ModulId, M.Modul FROM MODULE M WHERE NOT EXISTS ( SELECT PROJEKTMODUL.IdModul FROM PROJEKTMODUL WHERE M.ModulId = PROJEKTMODUL.IdModul AND PROJEKTMODUL.IdProjekt = 23 )
I do not understand whatselect distinct M.ModulId , M.Modul from MODULE M left outer join PROJEKTMODUL on M.ModulId = PROJEKTMODUL.IdModul and PROJEKTMODUL.IdProjekt = 23 where PROJEKTMODUL.IdProjekt is null
fact in the above rewritten query.PROJEKTMODUL.IdProjekt is nullHe is to perform an anti-jointure. As far as I know Oracle (starting with version 10g - I thought that release 1) rewritten a Join Anti that resembles your second query of your request NOT EXISTS and NOT IN.
Look at the results of the query without the predicate IS NULL and see what records (from this set) must be selected to show the same results as the first query. Areas of interest match the predicate IS NULL.

Join query not received from WLC
Hi all
I am in the process of autonomous update 1242 (MIC) APs belongs to an external client to make them a part of the existing lwapp based infrastructure.
I have seen successful negotiations of discovery. Then AP sends the join query, but the WLC debugging does not receive the product.
1. the capture of wireshark packages indicates that Discovery & jOin process use identical to each phased ports: it will be exclude firewalls.
2. no duplicate IPs
3 controllers are not exhausted with APs
4 DHCP option 43 is set up and could see it in action when I do a debug dhcp
Another interesting observation is that I couldn't see any CERT on autonomous before conveting to lwapp APs when I have HS crypto pki certificates
Please refer to the attachment for debugging output.
Any help is very appreciated.
see you soon,

Basically, I think, your outer join is ruined by the subquery correlated in the WHERE clause:
R.ToDate = (Select MAX(ToDate) from R r2
Since you joined outside R to A tell you the database to give you the lines of A for which R.ToDate is null * AND * meets your requirement: and this is not possible. Tom Kyte gave the classic explanation for this kind of problem long ago on AskTom: http://asktom.oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:4963137609733 ("ask yourself this - how a row in T2 (EMP in your example) the MISSING two (composed due to the outer join) AND have a column that corresponds to something?") It cannot be").

Thank you very much...MERGE into emp trg using(Select distinct b.ename ename,a.empno empno from emp a, emp_status b where a.empno=b.empno) src on (trg.empno=src.empno) when matched then update SET trg.name = src.ename; -
I just installed Firefox 5. Unfortunately, F-Secure "Application Control" now repeatedly appears "Change the Application" messages in an endless chain. It will not accept my attempts to 'Allow' the new version of Firefox. Since Firefox 5 is not compatible with F-Secure, I want to go back to my previous version of Firefox. I am very disappointed that you put me for all this trouble. How can I remove Firefox 5 and revert to the previous version of Firefox?
good new update for firefox 5 was released today

Tree view on the left of the Explorer of Windows 7 not synchronized with the file on the right.
1. create a shortcut to a folder.
2. click on the shortcut.
3 explore opens with the contents of the folder in the right pane, but the tree left is not synchronized with the location on the right. You must navigate on the left tree to get to the location of the folder on the right side. In the XP folder as this is done automatically.The whole point (I thought) shortcuts to specific locations in the directory structure was to avoid having to navigate several lower levels from the root of a tree...
Any way to configure the behavior of XP?
Thank you.
Hi Rptrevor,
· How you used to synchronize folders in Windows Explorer?
Follow the steps below to solve the problem:
a. right click on an empty space in the left pane (folder), you get a menu with two options
b. 'show all files' and 'Developing in the current folder'.
c. believing that the empty space is a bit complicated and the options are sticky (it's the same thing than to go through the 'Folder Options' dialog box).
I hope this helps.

My Ipad mini will not connect with my wifi at home. Other devices are connecting with the wifi at home. I turned the mini ipad market a few times and nothing. He recognizes wifi but when I touch the password, it continues to request the password. Help! It was working fine earlier in the day.
What has happened with your iPad since earlier today, when it worked? updated App or iOS? nothing at all
If your iPhone, iPad or iPod touch connects to a Wi - Fi - Apple Support network

Bug with an outer join, or & Analytics function (or rownum)
Hello
Seems to be a combination of an outer join, OR and rownum confuses the CBO.
First request is without rownum, the second is with rownum.
The second query expects 203 t lines and never ends. It should behave the same as query 1, with 24 M lines.
Remove the GOLD clause query 2 allows him to behave as a query 1, with 24 M lines.
We never saw it? Is there a solution?

Your question is compounded because of the join condition that forces a level of nested loops, which means that the table should be fully analysed once for each line of conduct rowsource. You can either transform the join in an equijoin and allow a hash to run, or you join could materialize the subquery once.
Allow the hash join:
SELECT count (*)
Message FROM
LEFT JOIN (SELECT hi.message_id, hi.update_dt
ROWNUM
OF message_hist salvation) PM ON (i.message_id = h.message_id
AND i.update_dt = h.update_dt)
LEFT JOIN (SELECT hi.message_id, hi.update_dt
ROWNUM
OF message_hist salvation) h2 ON (i.message_id = h2.message_id
AND h2.update_dt<>
AND h2.update_dt <> i.update_dt)

You may need to change the first condition to make sure that you select the correct subquery.
-edit
Not able to view a plan but you can invade the second join condition select and then the result of a subquery with a predicate according to your requirement. This should delay the or rating and leave only an equijoin (although rowsource return may be slightly larger than the opposite).
-Second edition, it did not work exactly when I tried it.
A hybrid of the previous two plans with a slight modification of how he was imitating the GOLD:

ROWNUM Clotilde

COALESCE(h.message_id,h2.message_id) message_id

Clotilde COALESCE (h.rown, h2.rown)
Message FROM
LEFT JOIN: ON (i.message_id = h.message_id
AND i.update_dt = h.update_dt)
LEFT JOIN: h2 WE (DECODE(h.message_id,,i.message_id) = h2.message_id - only try this if previous join returned NULL
