Meter of row/column for tables
HelloI know this is very basic, but so far the examples here that I dug up doesn't really do anything remotely to what I want.
I have 3 databases. Although they are defined as 'connections' in SQLDeveloper, I hope it is the same, that I'm still not used to the abstractions of Oracle.
Each has several tables. All I want is loop in each of the 3 DBs and number of journal lines and County table.
Say DB1:
Rows: columns:
Table 1: x y
Table2: x y
....
I really don't like what is inside of them. I found an example that does but it listed some system tables that are not part of my db. Change the "owner" has not really helped.
The value of the variable "Owner" means a database, which is correct?
Oh and I also don't care if the code is "inefficient", tables are not that big.
Thanks in advance.

If you mean you want only for specific schema / owner, you can add a where clause to interrogate or change the query and run it to scpecific user (schema). If you intend to run the specific user query the query would be something like below:
select table_name,count(*) over() count_table,column_name,count(*) over(partition by table_name) count_column from user_tab_columns

Serial number of PK column for table
Hi Experts,
I hung out and view object to the data control on the page jspx,.
First VO1 as ADF, as master and primary key (PkMaster)
Second VO2 as ADF Table, details and primary key(PkMaster,PkDetail)
I want to add a column autoincrement PkDetail do serial for every PkMaster for the table,
This autoincrements to the value with the number of rows in table
When to insert a new line.
Thanks in advance.

You can call this method after calling createInsert to detail to generate new sno and place it in the column
/**Method to generate Serial Number for Table * ***/public void generateSerial(String voName, String columnNm) {ViewObjectImpl vo = (ViewObjectImpl) this.findViewObject(voName);Row curRow = vo.getCurrentRow();Integer Srno = 0;Integer max = 0;vo.setRangeSize(-1); Row row[] = vo.getAllRowsInRange();for (Row r : row) {try {Srno = Integer.parseInt(r.getAttribute(columnNm).toString());} catch (NullPointerException e) {Srno = 0; }if (Srno > max) {max = Srno;}} max = max + 1;// System.out.println("Serial No is-" + max);curRow.setAttribute(columnNm, max); }just pass vo name and name of the pk column detail

R12 - equivalent column for table AP_AE_HEADERS_ALL GL_TRANSFER_RUN_ID
Hello
GL_TRANSFER_RUN_ID is a column present in the table of 11i AP AP_AE_HEADERS_ALL.
In R12 the equivalent table is XLA_AE_HEADERS. Can you please let me know if there is an equivalent column for the 11i GL_TRANSFER_RUN_ID column in tables of R12?
Thank you
Rumixla_ae_headers.accounting_batch_id is for creating accountants.
Think of xla_ae_headers.group_id to transfer the GL. Other columns to consider for transfer of GL are gl_transfer_status_code and gl_transfer_dateBy

Hide columns in Table B, based on values LOV in another row of the table:
Hello
Jdev 12.2.1.0
I have two tables A and B and I hide columns b based on the value of row of table A LOV. For example, I have a line in A table that has a column with the x, y, z values lov. Now, if I select the row in the table has and change the LOV to x, I had to hide some of the columns in the table (B) is there a way to get this feature? Any help would be appreciated.
Thank you
Assume:
1 table a call "DepartmentId" column this column has LOV.
B 2-table a column "ColumnInB" this column will be visible depending on the value of "DepartmentId".
Try to do the following:
1 - from data controls, drag "DepartmentId" attribute and drop it on the page as inputText then together make this inputText to false (you can remove it, but don't forget the corresponding binding in pageDef. not deleted).
2. copy the value of the inputText which will be as "#{bindings." DepartmentId.inputValue}"and go to the"ColumnInB"column and visible property beyond the copied value.
3 - the ColumnInB visible will be the condition as:
4-set DepartmentId autoSubmit = 'true '.
5-set table partialTriggers table B has id and id of DepartmentId LOV

I have a table of the adf, I added a column that contains a button that I created, when I click it must remove this row in the table, but it is not, please help
I don't understand. You use vo and eo for you to use business components.
Again, this kind of code call in trouble.
You must post the changes to make them visible to the eo find vo. You must then run the query for the changes in the business layer strips then you must update the iterator he table is based on.
In your code I see that happen, hooch maybe because it is more often than not formatted and undocumented.
My advice is to do a small test case that you can manage with easy sql. Once you get it to run transfer you the results to the actual application.

request to retrieve the value of the column and use in the other rows of the table
Hi all
I have a table where I maintain pairs name / value of a particular job. Now, I would like to see some of the values of the rows passed to other rows in a table for example
create job_name_value
(
VARCHAR2 (100) job_name,.
name varchar2 (100),
value varchar2 (100)
);
job_name name value TRGJOB % FPATH / USR/LOCAL/TRGJOB TRGJOB % FDATE CALDATE + 1 TRGJOB $FNAME1% %FPATH.mywatchfile1.%FDATE TRGJOB FNAME2% %FPATH.mywathcfile2.%FDATE TRGJOB % FNAME3 %FPATH.mywatchfile3.%FDATE can we write a sql query to produce output as below the objective is to use the value of fdate and fpath in the remaining lines. If there is no fdate and fpath then value should return such what or we need to use the stored procedure to achieve
/ usr/local/trgjob/mywatchfile1. CALDATE + 1
/ usr/local/trgjob/mywatchfile2. CALDATE + 1
/ usr/local/trgjob/mywatchfile3. CALDATE + 1
Hello
Since it cannot be '% FDATTE' or '% FPATH' (or both) then you need to replace each of them separately. If the other does not, there 'replacement' will do nothing, but this will not affect the result of the other.
Here's a way to do it:
SELECT REPLACE (REPLACE (n.value
'% FPATH.'
p.value | '/'
)
, '% FDATE '.
d.value
) AS output_value
OF job_name_value n
LEFT OUTER JOIN job_name_value p ON p.name = '% f '.
LEFT OUTER JOIN job_name_value d ON p.name = '% FDATE '.
WHERE n.name AS '\%FNAME%' ESCAPE ' \'
;
I hope that answers your question.
If this isn't the case, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
Report when the above query is to give erroneous results and explain, using specific examples, how to get the correct results of data provided in these places. If you change the query at all, your postal code.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

Disable the call to the listener of selection for certain cells of a row in the table.
Hi all
I have a table with 5 columns. I applied a listener of custom for this table in the bean selection. Now, what is my requirement, an action should happen in some specific cells in this table not all cells. So, how can I get that cell was clicked while the user selects a row in the table? If I can get my problem is apparently solved.
Help, please.You could do this by putting a client listener on the element inside the columns instead of a listener of the selection on the table. You will then get a server event that will tell you which column was clicked.

Name of tables listing the definitions of Web Forms row\column\POV
All,
We have some applications planning and a lot of Web forms to allow entry in varied combinations of row\column\POV. Users, it is difficult to locate the correct online with the combination of right row\column\POV form, to allow them to enter data and have to open\close a large number of Web forms before they find the right pair they need\want.
I know that the relational component of a planning application includes many tables store the definitions of Web forms, etc.. I would like to know where I could find a list of the tables that contain the definitions row\column\POV of each Web forms for each planning application in order to quickly identify the correct webforms who could access their data entry of support staff.

Paragraph style by default when you add rows/columns of the table
Hello
I use InDesign CC and whenever I add a new row in the table or a column, that paragraph for these lines styles are in default in the styles I won't use. They are actually failed to really big styles title so I don't just add lines 3 and 4 and my table is out of the page. None of the surrounding cells, columns or lines contain the ID styles is emphasizing the use.
How can I set the default style for a new row in the table or column?Thank you
Paul.
Hi, thanks for the help guys. I tried your suggestions but I always had the same problem. However I noticed that when the model documents have been opened there were styles by default selected in all the style panels. It seemed that it was these styles by default selected which were applied to new rows in the table.
I opened the templates and all the panels style [none] or [standard paragraph], then saved the document.
This solves the problem because no style is now applied when rows are added.

Scan of the columns in table for empty cells
I have prepared a form that will do the following (Please bear with me for the description):
The form opens with a table of 10 rows. The user must enter sides (from 0 to 10) in one of the columns in the table. Once the user enters all the ratings of ten, he or she must then click a button to turn on the rest of the form (which is hidden). What I'm trying to do is, after the button is clicked, scan the table to ensure that the entire column was filled with a number. If the column was made, then a second page. If a cell in the column was left in white, then I want a prompt to appear and indicate to the user which cell is empty. I was able to run by using the following code:
This code is under the event 'click '.
If (decisionMatrix.dMTable.Row4.rating.rawValue is nothing)
{
Poster a warning prompt that indicates the form is incompletexfa.host.messageBox ("incomplete form. Please fill in the background. ","warning ", 3);
}
on the other
{
Allow the user to save the current state of the form and activate the second part of the form.
app.execMenuItem ("SaveAs");
}The problem with the above method is that it checks only the Row4 cell. I have to add more code for the other 9 rows in the table and for each message box, indicating to the user which field to fill. Is there a better way to do it? A switch-case perhaps statement?
I have also considered the column full analysis at a time and just using a message box general for the table, using the following code:
If (decisionMatrix.dMTable.Row [*].rating.rawValue is nothing)
{
Poster a warning prompt that indicates the form is incompletexfa.host.messageBox ("incomplete form. Please fill all of the scoring. ","warning ", 3);
}...
But it doesn't seem to work. Any help is appreciated. Thank you.
The seal contains a table with 10 rows and 3 columns (a_, b_ and c_). The calls button 'Continue' by clicking on the click event, which runs through the table looking for NULL values in each column per row. The "ratingMissing" flag controls the visibility of the page 2.
Form1.Page1.Subform1.continueBtn::click - (JavaScript, client)
var ratingMissing = false;
for (var i = 0; i)< 10;="" i++)="">
var line = i + 1;
If (xfa.resolveNode("form1.page1.subform1.table.row["_+_i_+_"].a_").rawValue == null) {}
xfa.host.messageBox ("A is missing in row"+ row);
ratingMissing = true;
}
If (xfa.resolveNode("form1.page1.subform1.table.row["_+_i_+_"].b_").rawValue == null) {}
xfa.host.messageBox ("B is not in the line" + row);
ratingMissing = true;
}
If (xfa.resolveNode("form1.page1.subform1.table.row["_+_i_+_"].c_").rawValue == null) {}
xfa.host.messageBox ("C is missing in the row" + row);
ratingMissing = true;
}
}
If (ratingMissing == false) {}
Form1.Page2.presence = "visible";
}
else {}
Form1.Page2.presence = 'hidden ';
}

How can I write in a table cell (row, column appear) in a databae?
How can I write in a table cell (row, column appear) in a database using LabVIEW Database Toolkit? I use Ms Access. Suppose I have three columns in a table, I write 1 row of the 1st column, then 1st rank of the 3rd column. The problem I have is after writing the 1st column of 1st row, the reference goes to the second row, and if I write in the 3rd column, he goes to the 2nd row 3rd column. Any suggestion?
When you perform a SQL INSERT command, you create a new line. If you want to change an existing line, you must use the UPDATE command (i.e. UPDATE tablename SET column = value WHERE some_column = some_value). The some_column could be the unique ID of each line, date and time, etc.
I don't know what is the function to use in the Toolbox to execute a SQL command, since I do not use the Toolbox. Also, I don't understand why you don't do a single INSERT. It would be much faster.
CRUD for tables with large number of columns
Hello
I work for a government agency in Colombia, and we do a poll with about 1200 variables. Our database model has few paintings, but they have a large number of columns. Our Oracle 11 g database is, and we do not use Oracle APEX. I've read about APEX and it seems to be useful to generate quick forms and reports. However, I would like to know if it is possible to generate CRUD for tables with many columns, and that would be the best way to do it.
Thanks in advance.
Carlos.
With the help of 250 point on a single page is actually really bad for the user experience. I would probably be it cut into pieces and using several pages to guide the customer through it as a workflow.
You could also add some pop-up windows which includes some elements of your table, just saved on other pages. But I probably don't like that.

Request to delete rows for table fa_mass_additions
Helloo
I need help to remove rows from the table fa_mass_additions Oracle EBS of assets fixed r12
Each line is characterized by a unique recnum. However, there are duplicate for the Serial_number entries. I need to remove all but 1.
For example
Recnum 60341 Serial_number 1110007600100
Recnum 60342 Serial_number 1110007600100
Recnum 60343 Serial_number 1110007600100
Recnum 60344 Serial_number 1110007600200
Recnum 60345 Serial_number 1110007600200
Recnum 60346 Serial_number 1110007600300
Recnum 60347 Serial_number 1110007600300
Note-see duplicates for serial numbers
After the removal of table should be
Recnum 60341 Serial_number 1110007600100
Recnum 60344 Serial_number 1110007600200
Recnum 60346 Serial_number 1110007600300
Any query sql or pl/sql will be greatly appreciated

A backup point might be something to consider, but that would be your business decision.
An alternative workaround that might be used would be to go ahead and after some lines in the meantime, but it is accepted that this should not be an obligation, and the system should operate in a consistent way.
Can I deduce that the number is not filled, that this value cannot reproduce? If these lines have a tag number, I think that you can check in the version of FATagNumberValidator.class (run a check of the Apps for assets and check for this version of the file). If the instance is not already have version 120.0.12010000.2, your site can be helped in this scenario, the application of Patch 18800958 - ADI WEB: NO DUPLICATE tag ERROR IN SPREADSHEET NUMBERS. There is more explanation of this issue of tag number in the Doc ID 1944256.1.
In raising this question if, you made me realize that we cannot have similar validation for the serial number, or at least we do not have a named validator in a similar way. I have to do further research on this aspect, but if this is the case, I think that the best I could do would be to log an improvement to that request it.
