• Select random from the tables

  Another problem of mine, I hope we can clear the air:
  I have 4-5 tables with different products, these products have a price. In another table, I have just a column with a value (my money). What I have to do, he chooses one product from each table and the sum of all should not be greater than my money? A randomization but how?

  Hello

  You can create the source of the page as a SQL something like element:

  WITH X AS (
  SELECT ROWNUM RR, DRINKS.NAME || ' ' || DRINKS.PRICE || ' ' || F1.PRODUCT || ' ' || F1.PRICE || ' ' || F2.PRODUCT || ' ' || F2.PRICE || ' ' || DESERT.PRODUCT || ' ' || DESERT.PRICE OUTPUT

• read in select data from another table

  Hello world.

  IM Oracle11GR2 database.

  I m facing the following problem:

  I have 2 tables.

  In the first picture, I have a few articles and 3 of these items then come.

  (A) point Varchar2

  (B) Item Varchar2.

  (C) point digital and this point is the id of a record in the other table.

  If the digital point > 0 then points A and B must be read in the second table

  In the second table, I have 3 Articles.

  (A) the id of the record.

  B & C point are also point varchar2 and must be read in the first table, point C is > 0.

  I'm looking for the way that when I write a normal selection in the first picture he gives me the point B & C of the second table if C point in the first table is > 0.

  I thought to solve this problem with a trigger or something similar.

  Any idea is welcome.

  Regards to everyone.

  You don't need a trigger for this. A simple select statement should do. Something like that? I got your if condition perfectly.

  SELECT CASE WHEN (T1. C > 0) THEN (SELECT T2. B OF THE T2 WHERE T1. C = T2. (A) T1 OTHERWISE. END A,

  BOX WHEN (T1. C > 0) THEN (SELECT T2. C FROM T2 WHERE T1. C = T2. (A) T1 OTHERWISE. B END HAVE B,

  T1. C

  FROM T1;

  Look at the following example. Check if it fills your scenario.

  -BEGINNING OF THE SAMPLE DATA

  WITH T1 AS)

  SELECT 'A' A, 'B' B, 1 C OF DOUBLE UNION ALL

  SELECT 'C', ', 2 DOUBLE UNION ALL

  SELECT 'DF', 'G', THE DOUBLE 0),

  () AS T2

  SELECT 1, 'X' B 'Y' C DOUBLE UNION ALL

  SELECT 2, 'Z', 'BB' OF THE DOUBLE)

  -END OF THE SAMPLE DATA

  SELECT CASE WHEN (T1. C > 0) THEN (SELECT T2. B OF THE T2 WHERE T1. C = T2. (A) T1 OTHERWISE. END A,

  BOX WHEN (T1. C > 0) THEN (SELECT T2. C FROM T2 WHERE T1. C = T2. (A) T1 OTHERWISE. B END HAVE B,

  T1. C

  FROM T1;

  OUTPUT:

  A  B           C

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

  X Y 1 - since c > 0 A and B values in table 2 are replaced

  Z BB 2 - since c > 0 A and B values in table 2 are replaced

  DF G 0 - since c = 0, there is even value in table 1

• Form check synchronize on Popup to the selected record from the table

  I'm trying to recreate what I did on the portals of the OAS in Weblogic/ADF. I have JDeveloper 11.1.1.2.0. What I do seems to be a little different than the tutorials: I need something like the tutorial master-detail, but instead the details appearing on the same page, it should appear in a popup. I managed to build the part table/popup. But when the popup appears, it displays the wrong record. Here are the steps I used to create this page:
  
  After you create the ADF Fusion Middleware project:
  
  1 create templates for the tables I need.
  2. create the JSF Page.
  3 drop panelCollection on the page.
  4. remove my data to see in panelCollection control and choose the Table read-only ADF. Select the sorting and selection options.
  5 change table properties: selected = DisplayRow, EditingMode = clickToEdit
  6 drag the Popup on the page.
  7. remove my data from view in popup control and choose the form of the ADF. Select the send option.
  8 drop showPopupBehavior on the page. Name of the popup. The value triggerType to the 'selection '. (triggerType "click" works, too)
  9 deploy.
  
  The table is displayed. I click on a line. The pop-up window appears. The form of popup displays the first record in the table. I click on any line.

• Create the form for selecting data in multiple tables

  Hello

  I'm getting APEX for the first time and I just read 2 days dev Application Express guide

  I tried to play and I can't create a report with the form that select data from several tables

  What I want to achieve is a report we'll say 'USERS' makes MANAGER_ID ID, NAME, with a form that allows me to create, delete, change users

  The problem is that, once the report with the form created, if I click on create (to create a user) it will ask me for id, name, and manager_id

  I need a water drop down which allows me to select managers in the table manager instead of manually insert Director id

  How do I do that?

  Thank you!

• expdp + query option to export from several tables with the same condition

  Hello
  
  We want to export a subset of data only from databases to another. Both on AIX.
  
  Source/testdatabase 11.2.0.3 (non partitioned tables)
  Target productiion 11.2.0.3 database (separate tables)
  
  Tables of same names of columns but diffrenet structures a partitioning index and traget so only want to import content
  
  Each source datbaase hascolumn seq number table and want only to extract the last months of data.
  
  
  

  TABLES:table1,table2...
  DUMPFILE=dump_dir
  CONTENT=data_only
  QUERY= table1:"WHERE seq_num >100 "

  want to use expdp but not sure how to make sure that all tables have the seq_num WHERE > 100 condition, if let table1: go out and have just
  QUERY = "WHERE seq_num > 100"this condition would apply to all tables that we want."
  
  
  I'm assuming that can also use impdp CONTENT = data_only?
  
  Any ideas/thoughts?
  
  Thank you

  QUERY = "WHERE seq_num > 100"this condition would apply to all tables that we want."

  Yes, it will work for all tables, but ensure that all exported table must include this column.

  QUERY
  Default: no
  Goal
  Allows you to filter the data that is exported by specifying a clause of a SQL SELECT statement, which is applied to all tables in the work of export or a specific table.

  The query_clause is usually a WHERE clause for the selection of refined lines, but could be any SQL clause. For example, an ORDER BY clause can be used to accelerate a migration from a table in a heap in a table held in index. * If a [schema]. table_name is not provided, the query is applied to (and must be valid for) all tables in the export job.*

• DB connectivity Kit: syntax error in a SELECTION of data from joined tables

  Hello everyone

  I'm putting in labview a SQL query on joined tables.

  As an example I take a database to store the data of basketball 2on2 matches, which tables are

  corresponds to (matchId, Thomas, teamB)

  teams (teamId,PlayerAname, PlayerBname, nationality)

  nationalities (NatId, natName)

  To get an array of result with the game as well as the names of player as well as their nationality, I use this query on MySQL (which works on command line interface)

  SELECT MatchID,
  T1. PlayerAName, t1. PlayerBName, n1.natName,
  T2. PlayerAName, t2. PlayerBName, n2.natName
  MATCHES m
  INNER JOIN teams t1 ON t1.teamID = m.teamA
  INNER JOIN teams t2 ON t2.teamID = m.teamB
  INNER JOIN nationalities L1 ON n1.natID = t1.nationality
  INNER JOIN nationalities n2 ON n2.natID = t2.nationality

  When I put it in labview, using the block 'select data', I get a syntax error as shown in the attached screenshot.

  

  Am I something mistanking using the JOIN examples statements or aliases?

  Thanks in advance!

  The select VI is designed to be a simple way to select from a table. I doubt that he can do joins (and would not certainly need the 'FROM', even if it can). What you can do instead calls the query execute VI and give him the complete SQL query. I don't remember if it returns the data in the recordset object, so you must do so separately.

  I wonder you can not create a report by selecting from multiple tables?

  If you can please I need your help.

  Thank you

  You can, but in this case, it might be easier to build your report tables that are joined Oracle views and then build your report out of the newly built sight...

  Or wrap a selection around your selection with joins, and then make the where clause on the external selection...

  Thank you

  The following is correct?
  
  (I am connected to a local database)

  I think, that you can create dblink wihtout any problem yet, it's a PROD. After your selection, you can drop dblink

• Update with select table from another table

  Hallo,
  
  I'd like to update table b with a mapping a table codes.
  
  one has:
  
  town_id, town_code, town_name
  
  b town_code, town_id, town_population, town_zip_code...
  
  Table a has all the details - town_id, town_code and town_name and acts as the mapping between town_id and town_code
  
  In table b, town_code is null. I want to update the column b.town_code with town_code table where a.town_id = b.town_id.
  
  How the update query will look like?
  
  I tried
  UPDATE B SET town_code = (SELECT A.town_code FROM A, B WHERE A.town_id = B.town_id)
  
  and I get the error "einreihig subquery returns several lines.
  
  You will appreciate your assistance

  OK, now I see where you went wrong.

  It's your query:

  UPDATE TOWN_INFO
  SET TOWN_CODE=(SELECT B.TOWN_CODE FROM TOWN_MAPP B, TOWN_INFO C
  WHERE B.TOWN_ID=B.TOWN_ID)
  /
  

  You have added an additional TOWN_INFO table reference in your subquery. You really wanted to refer to the TOWN_INFO in your UPDATE statement for that to be a CORRELATED subquery. Delete this reference as I did below.

  Here's the correct query:

  UPDATE  TOWN_INFO TI
  SET     TOWN_CODE = (
                          SELECT  TOWN_CODE
                          FROM    TOWN_MAPP TM
                          WHERE   TI.TOWN_ID = TM.TOWN_ID

  Hello
  
  I have a question where I'm supposed to retrieve the address of an account id-based billing. However, the table of billing may not have an address. There is a table of addresses that always has an address for an account. If the billing address exists, it should be used, so I can't use the address table. Is it possible in a select statement to query to the billing address and if it does not exist, use the address table.

  SELECT * FROM accounts a, b billings WHERE a.accountid = b.accountid

  Any help will be greatly appreciated.

  I think you need to explain more clearly if

  -you only have a couple of "billing" columns which is empty and in this case, you want to use the columns from the table 'accounts '.

  - or you have a join with another table that doesn't return data, for example a foreign key "address_id" "billing" is zero and therefore the join to other tables 'address' will return all the data

  In the first case, you have already been provided with some examples here, how to use NVL or similar functions to achieve, even if the first post first evaluates the information of 'accounts' and if it is white using information from "billing". According to your description you need the other way around. The second post a subquery recursive useless in my opinion.

  In the latter case, you should probably use an "outer" join so that the data in your table "bills" are returned, even if the join to another table is not at all the lines.

  SELECT
  NVL(AD1.ADDRESS_ATTR1, AD2.ADDRESS_ATTR1) as ADDRESS_ATTR1,
  NVL(AD1.ADDRESS_ATTR2, AD2.ADDRESS_ATTR2) as ADDRESS_ATTR2,
  NVL(AD1.ADDRESS_STREET, AD2.ADDRESS_STREET) as ADDRESS_STREET,
  ...
  FROM accounts a
  INNER JOIN billings b
  ON a.accountid = b.accountid
  LEFT OUTER JOIN address ad1
  ON b.address_id = ad1.address_id
  INNER JOIN address ad2
  ON a.address_id = ad2.address_id;
  

  In this way you pick up the address stored in the "invoices" table, if it existed, otherwise you pick up the address assigned to the "accounts" table I used an inner for the second address join join because you said that the account always has an assigned address.

  Kind regards
