• How to display the list item values both from 2 different tables?

  Hello world.

  I have a problem for the display of the data.

  There are 2 tables in the database.

  Table-1 has lc_value, lc_no, lc_dt, and vendor_code columns.

  Table-2 has vendor_code, $vendor_name & vendor_address.

  I created the form where I display data in list item 30 (tabular presentation - 30 records displayed).

  I need to display all values automatically at the same time in the form just by clicking on "Enter_Query" and "Execute_Query".

  It worked when the form had fields in a table in a single table.

  I created fields in a table for tables; then created the relationship between the tables by using the join (vendor_code).

  But when I run the form, click on "Enter_Query" and "Execute_Query", its does not work.

  Oracle9i Enterprise Edition Release 9.2.0.1.0 - Production.

  How can I do this?

  Help me.

  Thank you.

  Dear Bruno,

  Each provider code is to have a folder, then

  Why keep two tables?

  Why you want to update both the table at the same time?

  Master / detail means,.

  a master record depends on several detail records.

  Please, understand and try to build your form with single table.

  If you have already created 2 tables, then merge these into a single table.

  Or other wise keep table_1 as a database block and to vend_name as a data field (element of database in the palette of the property is set to 'no').

  Then go to the trigger of table_1 block post_query and write the following:

  Select vend_name in: vend_name from vendor_mst where vend_cd =: lc_vend_cd;

  In doing the above, the form will look as you wish but the change on the vend_name not to be saved because that is the point of no database.

  Other than vend_name all fields in table_1 will be recorded.

  Hope this will help.

• Process in two different tables in one page

  Hi all

  I have A form with a submit button, when I click on the button I want to send the data from two different tables. For example:

  REQ_ID: 221

  BOX_NUMBER: 2

  NOM_ELEMENT: APPLE

  COUNTRY_ORIGIN: USA

  I want to send all the information in table 1 and only REQ_ID and BOX_NUMBER in table 2.

  I tried to create processes two different which are:

  1. the usual process line DML for table 1 and;

  2. simple query 'Insert' SQL for table 2

  It seems fine, until I realized that when the user tries to update the BOX_NUMBER to 10 for example, only 1 table is updated and table 2 creates an another duplicate data instead of updating the old one! This also applies to my button Delete,.

  any idea to fix this problem?

  Thank you very much

  Vika

  Reread what you wrote and you would realize why 2nd table only "new lines".

  2. simple query "Insert into ' SQL for table 2

  If you need to UPDATE the table, then you must write a simple UPDATE statement.

  If you want to REMOVE from the table, then you must write a simple DELETE statement.

  I call this "DML DIY" - do it yourself DML

  (personally, I'd probably use MERGE for INSERT and UPDATE)

• Select values from the db1 table and insert into the DB2 table

  Hello
  
  I have three databases oracle running in three different machines. their ip address is different. among the DB can access databases. (means am able to select values and insert values into tables individually.)
  
  I need to extract data from the DB1 table (ip say DB1 is 10.10.10.10 and the user is DB1user and the table is DB1user_table) and insert the values into DB2 table (say ip DB2 is 11.11.11.11 and the user is DB2user and table DB2user_table) of DB3 that is to have access to the two IPs DB.
  
  How do I do this
  
  Edited by: Aemunathan on February 10, 2010 23:12

  Depending on the amount of data must be moved between DB1 and DB2, and the frequency at which this should happen, you might consider the SQL * COPY more control. I think it's very useful for one-off tasks little, so I can live within its limits of the data type. More http://download.oracle.com/docs/cd/E11882_01/server.112/e10823/apb.htm#i641251.

  Change some parameter of sqlplus session are almost mandatory in order to get decent transfer rates. Tuning ARRAYSIZE and COPYCOMMIT can make a huge difference in flow. LONG change may be necessary, too, depending on your data. The documentation offers these notes on use:

  To activate the copy of data between Oracle and databases non-Oracle, NUMBER of columns is replaced by DECIMAL columns in the destination table. Therefore, if you are copying between Oracle databases, a NUMBER column with no precision will become a DECIMAL column (38). When copying between Oracle databases, you must use SQL commands (CREATE TABLE AS and INSERTION), or you must make sure that your columns have a specified precision.

  SQL * the VALUE LONGER variable limits the length of the LONG column you are copying. If all LONG columns contain data exceeds the value of LONG, COPY truncates the data.

  SQL * Plus performs a validation at the end of each successful COPY. If you set the SQL * variable more COPYCOMMIT DEFINED to a value positive n, SQL * Plus performs a validation after copying all lots n of records. The SQL * Plus ARRAYSIZE variable SET determines the size of a batch.

  Some operating environments require that the service names be placed between double quotes.

  From a SQL * Plus term on DB3, can resemble the command to move all content from my_table in DB1 to the same table in DB2

  COPY from user1/pass1@DB1 to user2/pass2@DB2 -
  INSERT INTO my_table -
  USING select * from my_table
  

  Note the SQL code * more line-continuation character ' - '. It is used to escape the newline character in a SQL * Plus command if you do not have to type all on one line. I use it all the time with this command, but I can't locate the documentation on that right now. Maybe someone else can put their finger on it.

  There are other ways to accomplish what the command copy and it is not without its quirks and limitations, but I find that there is usefulness in an Oracle Toolbox.

• Select Max (Date) in two different tables...

  Dear all,

  I need the date of last update of two different tables, I mean max (date). We will update one table at a time. Updated once I need to take the last update.

  It can be either in table A table B.

  for example.

  Table A

  Date of the ID

  100 16/05/2014

  101 20/05/2014

  102, 22/05/2014

  Table B

  Date of the ID

  100 04/06/2014

  101, 26/05/2014

  102 21/05/2014

  I need the date of table B (101 26/05/2014) last updated date...

  Hello

  Another way, using much more GRAND:

  SELECT LARGER (max1, max2) x

  FROM (SELECT MAX (mydate) max1

  OF mytable_a

  )

  (SELECT MAX (myotherdate) max2

  OF mytable_b

  )

• Variable from PL/SQL table?

  Hello
  
  I need to process some data in PL/SQL.
  The first thing I would do, is to write a query that collects all the mydata from different tables in exactly one table on which I can make simple queries.
  
  What is the preferred way to do this?
  Temporary table, or view, or something else?
  
  I would preffer not not to create the physical table for this. I want to use only a PL/SQL variable.
  
  Thank you

  Hello

  Thanks for your advice, but I would still do it.
  Is it possible or not? (fully searchable custom table in a PL/SQL variable)

  Yes and no.
  Yes, it is possible to get all your data and put it in a PL/SQL 'table' (better known as an array or a collection, because they are not tables)
  No, you will not be able to 'interrogate' the data in this array/collection, simply because there isn't a table, and SQL will not work against it.

  You can do all kinds of PL/SQL code to process the data in the table or the collection to simulate what would do SQL, but it will be several times slower than that of SQL, and to be honest, no expert here is likely to give you code to do because it's just the wrong way to do things.

  If you can give a legitimate situation where you needed to load the data in a table or the collection in order to treat it, then of course someone can show you how to do this, but it is likely that most of the situations describe you would be better made using SQL tables from database etc..

• Select cursor for update: multiple columns of different tables

  Hello
  
  I have two tables test1 and test2. I want to udpate the column (DEPT_DSCR) from the TEST1 and TEST2 using select for update and current tables of the... with the cursor.
  
  I have a code drafted as follows:
  DECLARE
  v_mydept1 TEST1. TYPE % DEPT_CD;
  v_mydept2 TEST2. TYPE % DEPT_CD;
  CURSOR C1 IS SELECT TEST1. DEPT_CD, TEST2. DEPT_CD OF TEST1, TEST2 WHERE TEST1. DEPT_CD = TEST2. DEPT_CD AND TEST1. DEPT_CD IS 'AA' FOR THE UPDATE OF TEST1. DEPT_DSCR, TEST2. DEPT_DSCR;

  SETTING A DAY TEST2 SET DEPT_DSCR = 'PLSQL2' WHERE CURRENT OF C1.
  END LOOP;
  COMMIT;
  END;
  
  The code above when it is run, declares that it runs successfully. But it does not update the columns you want [DEPT_DSCR].
  
  It works only when we want to update one or more columns of the same table... i. e by providing these columns after ' to UPDATE THE.
  I don't know what exactly is the problem when you want to update several columns of different tables.
  
  Can someone help me on this?

• Display and update of fields in different tables on the same page.

  I am facing two problems...
  
  (1) I have a report on which I show several fields of 4 different tables. For each row of data, there is a link to change on the first column. By clicking on the link change, I show you a form where I want to show the respective data. On the link change, even if I send you the data in the report, they do not appear on the form (what edit link is clicked). Also, there is only room for 3 items to ship through the link change.
  How to display the data correctly on the form? Is there another way to use the link change?
  
  (2) on the form, how do I update the data from different tables?

  Hi Lisa,

  The text of presentation on the INSTEAD OF triggers is in: [http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_7004.htm#sthref7918]

  First of all, your SQL View contains a unique key so that your triggers and the two Apex know what is updated.

  Then, you can create instead of triggers for "instead of INSERT ON viewname", 'instead of UPDATE ON viewname' and 'DELETE ON viewname' on your SQL view. What do these triggers depends on what you need. In the trigger code, you refer to new data using: NEW.column_name and old data using: OLD.column_name (updates both: OLD and: NEW values).

  I'm not sure of the SEPARATE, the GROUP IN question. You would certainly have a unique key on each record. It could be that the DISTINCT or GROUP BY clause will have to be taken out of the SQL view and is part of the source of the region, so that the SQL view does nothing with the data other than to join several tables in a single "table" from the Primary Key/Foreign Key relationship.
