BLOCK BASED ON TWO TABLES

I've created a block based on two tables.
Querying records works fine.
However, when I try to amend a column in the master table I get an error message 'Record has already been updated by another user.'
I have set the dml target property to to the master table and set the primary key on the correct columns.
What else could there be??!!

Block1 will be----- enter_query Sku :123 then from dropdown select Level 1 which will show data like this
in two different rows.
Sku       : 123       Price : $100        Qty : 10   (Primary)
Sub Sku   : 345       Price : $110        Qty : 8   (Level 1)then from dropdown selected Level 2 which will show data like this in two different rows.
Sku       : 123       Price : $100        Qty : 10   (Primary)
Sub Sku   : 456       Price : $90         Qty : 12 (Level 2)There are two more blocks which will display more information based on either Level 1 is selected or Level2 selected.

One block based on two table when update/insert result in FRM-40654

Hi,
I ahve a multi line block based on two tables.
Customers - AFCUSTOMER
Maintenance - AFMAINT
Some customers exist when maintenance doesnt so in my where clause i have
AFCUSTOMER.CUSTID=AFMAINT.MAINT_CUSTID(+) AND AFCUSTOMER.CUSTBRANCHID=1 AND AFCUSTOMER.CUSTSTATUSID=2
I have primary key set as the AFMAINT table primary key and have set DML data targetr name as AFMAINT.
I am displaying customer name (from AFCUSTOMER) and type of payment (from AFMAINT) on screen and i want to change the type of payment which then uses pre update trigger to fil in the primary key of AFMAINT.
Querying works fine and displays all records. But when i try to insert a record into the AFMAINT table by changing the type of payment list item i get FRM-40654 Record updated by another user. I have checked and block status is QUERY right before the list item is changed.
Any ideas on where i am going wrong.

But when i try to insert a record into the AFMAINT table by changing the type of payment list item i get FRM-40654 Record updated by another userWhen you start editing a record which is already stores in the database forms "rereads" the record from the database and check id all values in the database are the same as in the form. If there is some difference, forms assumes that someone else changed the record after you did the query.
The main causes for that are:
-Some database-trigger which changes the value of a column which is included in the form
-numeric column with a higher precision in forms, than in the database
-a block based on a view or "select from clause" which does not return the same values as inserted/updated through forms.
I guess you run into the third issue. Check all the values in the forms-items after your dml and compare them to the values saved to the database, there will be some difference. If you find it, correct the error, if one, or re-read the data in the POST-UPDATE-trigger.

Detail tabular form based on two tables

db11gxe , apex 4.0 , firefox 24 ,
hi all ,
i have a master detail form based on two tables , the detail form ofcourse based on one table , the problem is i want to include a column of another
table into the tabular form , so i have changed the query of the tabular form and included the column in it correctly ,
but the problem is about saving data , i can not save the data , i think
because the "mru" process is based on one table , that is because i face an error talking about "mru" process when i try to save the data ,
Error in mru internal routine: ORA-20001: no data found in tabular form Unable to process update.
so
what should i do to save the data ? should i create another "mru" process based on the other table or what ?
thanks

Anything beyond "simple" requires that you do it yourself. I believe that what you want is "beyond simple"
As far as I know, you can only use the 'mru' on one table.
(I could be wrong)
If the conditions are right, you might be able to simplify things such that you can use the 'mru'.
ie CREATE VIEW on the two tables.
However, you need to understand how Oracle treats DML operations on views, what type of views can be updated, etc., etc.
If just creating the view doesn't work, creating an INSTEAD OF trigger on the view come to mind...
(lol) - at that point, you have already started down the 'dark path' of creating your own 'MRU'
personal note: triggers have a really baaaddd habit of hiding code from other developers. you are better off, in the long run, creating your own 'mru'..
ie a package with procedures to handle INSERT, UPDATE, and DELETES

Does adding a field to a table affect a data block based on the table?

If I make a change to a table like adding a field does it affect data data blocks based on the table?

The other place I have seen where adding a new column to a table causes problems is when a programmer codes: Select * from table.
If that is coded in a form, the form will need to be recompiled before it will work properly.

Can I create a view based on two tables that have the same column name?

I have two tables A and B. Each table has 50+ columns.
I want to create a view that includes all the columns in A and all the columns in B. I created a view with a select statement that says
Select A.*, B.*
From A, B
where A.id = B.id
It returns an error because in each table I have a column that keeps track if a record has been changed called Modified_By. That's where it chokes up on I figure. I would like to write the view without explicitly writing each column name from A and B as part of the select statement. The actual select statement works fine and only bombs when trying to turn the select statement into a view.

You will have to type the full column list at least once. You can save a few keystrokes (i.e. alias. on every column) by providing the column names to the CREATE part instead of in the SELECT part. Something like:
SQL> desc t
Name                                      Null?    Type
ID                                                 NUMBER
NAME                                               VARCHAR2(10)
SQL> desc t1
Name                                      Null?    Type
T_ID                                               NUMBER
LOC_ID                                             NUMBER
NAME                                               VARCHAR2(15)
SQL> CREATE VIEW t_v (id, t_name, t_id, loc_id, t1_name) AS
2 SELECT t.*, t1.*
3 FROM t, t1
4 WHERE t.id = t1.t_id;
View created.HTH

Defining a Recordset Set based on two tables

I am having difficulty displaying records for a "membership"
page. I have set up a simple database in PHPMyAdmin with two main
tables: instructors and membership. Instructors are given a
temporary username and password to enter a restricted area. If they
decide to become a member, they go to a page with a
Pre-registration
form and fill that in. If their credentials check out, they are
sent a registration form.
The pre-registration form populates the instructors table.
I set up three pages in the Admin area: Contact_info,
Addresses, and Membership.
The Contact_info has the instructors' email and phone
numbers. This is based on some of the fields in the instructors
table. This page works fine.
The Addresses page also is populated fields from the
Instructors table and also works well.
The membership page is not working. I want this page to
display fields from the Instructors and the Membership tables.
Here's the SQL statement that I am using in the Recordset
dialog box in DW:
SELECT instructors.instructor_id, instructors.first_name,
instructors.last_name, membership.instructor_id,
membership.username, membership.pwd, membership.type
FROM instructors INNER JOIN membership ON
instructors.instructor_id = membership.instructor_id
ORDER BY instructors.last_name
It seems to me to be correct but its not displaying any
records. I don't know if the sql statement is bad or I have my
instructor_id field in my Membership table set up incorrectly in
PHPMyAdmin. I don't know how to indicate that its a foreign field
or how to relate it to the other table, other than indication the
relationship with sql. By the way, did I mention that I am new to
php and sql?
I appreciate any help.

Just and idea.
Try to create one dimension like this:
Id
type
Category
1
juice
drink
2
milk
drink
3
alcohol
drink
4
beer
liquor
5
wine
liquor
Hope this helps.

Hi
You need to append every article number after each select is performed
is this an intermal table ZOXE1D0041 with header line ? if yes
then do this way
select WLK1~ARTNR
into ZZARTICLE
from WLK1 INNER JOIN T001W
ON WLK1FILIA = T001WKUNNR
where WLK1~PFLKN NE 'P' AND
WLK1~PFLKN NE 'S' AND
WLK1~QUELL NE '2'.
ZOXE1D0041-ZZLISTARTICLE = ZZARTICLE.
Append ZOXE1D0041. " <edited>
endselect.
then ZOXE1D0041 will have all article numbers.

Question - View with a join based on two unequal strings.

Hello -
First my apologies for the likely novice question.
I'm creating a view based on two tables as such:
SELECT *
FROM table1 LEFT OUTER JOIN table2 ON table1.string = table2.string AND table1.number = table2.number
Problem: table1.string looks like "A00A01%%%" and table2.string looks like "A1" (which would correspond to "A00A01%%%".
Question: Can I create the join based on the 4th and 6th character of the string = the other string, or should I create a view with a formula creating a new field and then create a second view? (Note: creating or changing the field in the original table is not an option).
Thank you.

Hi,
Yes, you can do that. Join conditions don't have to be as simple as "ON a.col1 = b.col2"; they can involve functions, like CONCAT and SUBSTR.
For example:
FROM            table1
LEFT OUTER JOIN table2
ON              SUBSTR (table1.string, 4, 1)
                ||
                SUBSTR (table1.string, 6, 1) = table2.string
...The query might be faster if you create a function-based index on the join condition from table1. This does not require changing table1 itself. (For a LEFT OUTER JOIN, like this, it probably won't matter.)

Data Blocks Based on Stored Procedures

Is it possible to to create a data block based on a stored procedure, and create a dynamic list as a drop down box?
I have a form that runs successfully that has a data block based on a stored procedure. I add my trigger to create and populate the record group. Then in the Property Palette, when I change ITEM TYPE from TEXT ITEM to LIST ITEM, I receive the following runtime error:
FRM-40350: Query caused no records to be retrived.
Note: the tlist/list item runs successfully on a data block based on a table.

1) go to the block property to remove the same item column, then re-add the item; Since the property may remember the old text type;
make sure the record value for the list tiem from stored procedure is among the list elements!
Last sort is to do:
2) you may re-create your gui based on the table by setting the list type this time, then set the block property to be based on the stored procedure.

Joining Two Tables by Database View

HI There,
I'm trying to join two tables BNKA and LFBK to get the Bank details according to the requirement.
Now, I wanted to go head and create a Generic datasource and bring the fields from these two tables by Vew.
Can someone please explain me step by step to create the database view?
One more thing, do we need to have anything in common between two tables BNKA and LFBK ?
I really appreciate if someone can guide me through step by step method to create Database Table view?
Thanks
Madhuri

Hi Madhuri,
With out having common fields, we can not create data base view based on two tables.
1) goto SE11
2) select data base view and give the name and create.
3) in left side give the tables names
4) In left side define the relation
check the below article

Two Tables in a Single Block!

Is that possible two tables in a single forms block.
actually we can assign one database table in a block
but i like to know is there any possibilities of having 2 tables in a
block?

Stalin,
Yes, this is possible. Essentially, you are performing a join on the tables in your block which means you have to fully qualify each column in the block so Forms knows which column belongs to which table. For detailed information take a look at the Oracle White Paper: Basing a Forms Data Block on a Join. This works quite well and the tables your block is based on is fully updatable, whereas if you were to create a view and base your block on the view, most likely your view would not be updatable.
Hope this helps,

Spliting a table in to two table based on the groups in SSRS

Hi,
I am trying to a split a rows accross two tables based on a group.
So far I have added a list and added a row group and grouped it using lineof business
Inside my list i have two identical tables so i can display the data
for the first table i have set the row visibility as follows: where LineOfbusiness1 is the groupname of my list group
=RowNumber(Nothing) >= (IIf(CountRows("LineOfBusiness1")\2 = 1, CountRows("LineOfBusiness1")/2, (CountRows("LineOfBusiness1")/2)+1))
and for the second table in the i have set the row visibility as follows
=RowNumber(Nothing)< (IIf(CountRows("LineOfBusiness1")\2 = 1,CountRows("LineOfBusiness1")/2, (CountRows("LineOfBusiness1")/2)+1))
this set up works fine for the first group but it doesnt display the data the way i want for the subsequent groups.
so how do i have the table start over after each group... plus in my group i have specified to do a page break after everygroup...
Any help will be appreciated.
Thanks
Karen

Visakh,
Thanks for answering.... a sample for the data will look like
dataset----
create table #dataset
Code varchar(5),
Name varchar(200),
Lineofbusiness int,
Statename varchar(10),
typed int,
description varchar(2000)
insert into #dataset
select 45111,abc,1,AL,4500,policies
insert into #dataset
select 45111,abc,1,AL,2500,vehiles
insert into #dataset
select 45111,abc,1,AL,3,drivers
insert into #dataset
select 45000,bca,2,AL,4500,policies
insert into #dataset
select 45000,bca,2,AL,500,house
insert into #dataset
select 45000,bca,2,AL,40,theft
When i display the data i want it to be
Line of business 1
policies 4500 drviers 3
vehiles 2500
Line of business 2
Policies 4500 theft 40
House 500
but right now the for lineofbusiness 1 its showing the correct way for but the line 2 everything is being displayed in the right.
Thanks

I’m trying to create Pivot that has filter on Week number to show the number of orders, Sum of Production time in minutes and the total of the values form the lookup table dLookupList that matches the work center and the selected week
numbers. So that I can calculate the total time for each work center. Filter criteria is Week number and Work center.
For example if someone select all weeks numbers the result sould look like this
Week number
(All)
Work center
Count of order number
Sum of Production time in minutes

How can I relate these two tables to get the above result?
Any help is highly appreciated.

Hi Recio
Thank you very much for the swift response. I was able to get it work.
I got two questions:
How do you add a total time column to the pivot table like you did? Because there are no calculated field in power pivot.
I prefer that the filter is based on the Orders table. So that if you select all Week numbers in the filter, that pivot will show result for all orders and relevant sums from the lookup list.

For example: I add Week number 5 to the work center “a”
Week number
