The query results reel in a file and the number of lines in a different file
HelloI would like to export only the result of my query to a file. I am able to do this with several sql, but I want the number of selected lines in a different file than the output "log".
For example:
-------------------------------------
Select 'TEST' for the DOUBLE;
TEST
+ 1 row selected. +
-------------------------------------
So 'TEST' should be included in the results file and ' 1 selected line"to a different log file.
Is it possible to achieve this sql * more.
Thank you for your time
Rodriguez,
Hi, Rodriguez,
Welcome to the forum!
Here's one way:
COLUMN row_cnt_col NOPRINT NEW_VALUE row_cnt
-- You may or may not want the following settings.
-- The 2-file output works with or without them.
SET FEEDBACK OFF
SET VERIFY OFF
SPOOL dept.txt
SELECT deptno, dname
, COUNT (*) OVER () AS row_cnt_col
FROM scott.dept
;
SPOOL OFF
SPOOL dept.log
SELECT &row_cnt AS total_rows_found
FROM dual;
SPOOL OFF
The first SPOOL file, dept.txt, looks like this:
` DEPTNO DNAME
---------- --------------
10 ACCOUNTING
20 RESEARCH
30 SALES
40 OPERATIONS
The second SPOOL file, dept.log, looks like this:
TOTAL_ROWS_FOUND
----------------
4
Taking your example, only the first query should change:
SELECT 'TEST' AS output
, COUNT (*) OVER () AS row_cnt_col
FROM dual
;
The second query and all the stuff set up is exactly the same.

Move and organize files based on the number of lines
Hello
I have a directory containing files nearly 1,500, some of which are composed of 12 lines, some of which are composed of 4 lines, which are all .phy (PHYLIP) files, which can be viewed in Notepad/wordpad as text files.
I need to execute a script which will determine the number of lines in each file and move them to the corresponding folder. The file size will not work for sorting, I've tried.
that is, all files with 4 lines in one folder, all the files with 12 lines in another folder, any files left (so I can be sure that everything has been inspected) in the main directory.
Can anyone help?

Is it possible to change the number of lines to display in the query of the adf?
Hello
is it possible to change the number of lines that appear in a query of the adf that is similar to a form of the adf?
I need about 5 lines per column rather than display all the fields in a single column to display? Thank you.
Hello
What do you mean that it didn't work? Attributes of how you have in the Panel of the query? Maybe you have fewer number than the combination or lines and the properties of the argument maxColumns attributes.
Try again with
and see if you are able to get everything under a single column. If you get, play with these two properties to get the desired result.

I'm looking to translate observations. I know I can "Export all data filing" and import comments into a new file. It is that the new file has the same content and the number of pages with slightly different margins. So far when I try to import comments from a previous version alignment off based on the margins. Is there a way to reduce the old doc to match margins to avoid manually move all comments?
Hi Joseph
Comment positioning matches that of the folder from which they were imported. Please see using Acrobat | Import and export comments for more details.

Problems with sorting of columns and the number of lines in the report
Hello
I'm having a problem with sorting of columns and the number of lines displayed in a report.
This report displays the data correct, but if I try to sort on a column when I click on the column heading in the report returns no line... I need to click on the "go" button to refresh the report (with the column sorted now) in to display the data.
Similarly, I display only 15 lines per page. If I try to view the lines 16-30, 31-45, etc., that it returns no line until I click on the 'go' button to refresh again.
Has anyone else had (and overcome) the same problem?
Thank you
JosephJoseph,
2 questions:
1) are you using the elements referenced by the report page to filter etc.. ? If so, you're failing values of these when the loading of the page?
(2) are you using PPR page through the results?If so, it could be a problem with the different types of session state, as Anton Nielsen blogged about here:
http://c2anton.blogspot.com/2008/12/Oracle-Application-Express-Apex-three.htmlIf so, you can use calculations or processes to set element values in session state persistent during page rendering, as Anton mentions. In this way, when you use PPR page values will be available in session state and your report should work fine.

BI Publisher - how to display the number of lines displayed at the bottom of the table on each page
Hello
We are the conversion reports Actuate BEEP and not able to understand how to view "Accum.Total = < n >" at the bottom of each page. In the attached report to operate it, "Accum.Total = < n >" must be displayed at the bottom of each page where < n > is the number of lines displayed on the current page and previous page.
For example, if there are 10 rows in the result set, if the 1st page displays 4 rows, 2nd page displays 3 rows and 3rd page is 3 lines and then Accum.Total = 4 on page 1, Accum.Total = 7 on page 2 and Accum.Total = 10 on page 3.
Note that we use the property table "allow the lines to break Pages = False" as we do not want a specific line can be split across pages.
I enclose a sample of report actuate, rtf, BEEP and XML report for testing file.
Approach used so far-
1 > I tried to put the counter in the footer, but it seems that only the fields that come directly from the IC can be used on the header/footer. No matter what form text field or variables defined in the report.
2 > I used approach given in the link below. Using this approach, I am able to view a coded value hard at the bottom of every page (just below the table) but his does not work for the variable (in my case the counter c1).
https://blogs.oracle.com/xmlpublisher/entry/continued
3 > on Google, I found a few articles on the page break conditionally as display only certain numbers on a page or the page by section break but in our case, its dynamics and its number of lines to display on a page is driven by data, so I could not think of a certain condition to use in "Condition." ": If" for use as a page break.

Can I limit the number of lines of text entered into a TextArea?
Hello
I use Flex Builder 2 to create an application that allows users to enter text in different TextAreas and eventually create a PDF file with their different text. My only problem is that I can't limit the number of lines of text used in each text box. I can limit characters by using maxChar, but this does not take into account a user entering multiple presses "return" - this does not affect the character limit, but can result in the final PDF layout (spitting the text on page 2).
Is there a way to keep track and limit the number of lines of text in a text box (in Flex 2)?
(Ideally I won't disable the ability for users to use the 'back' button to create several paragraphs)
Any help would be appreciated.
Thank you

Column data reading according to the number of lines
Hi guys,.
I am currently stuck on the problem of recovering the data from my database (MS Access) according to the number of lines, he has at any time (without having to know how many lines there will be during the programming of this part).
First, I show how my program works. I'm working on an automated food, order and after the customer has chosen his power, system information such as the name of the food, quantity and price of the food will be written to the MS Access database table. (for example table name "Orderingtable" in MS Access) For my case, 1 order of food will occupy 1 line of the database table. In other words, as part of the same, if he orders 3 different foods, 3 rows will be filled in my database table.
I would then get the part number of 'Quantity' for each order of the database and summarize the amount finally to count the total number of orders in the table of database at any time. This addition of result will be then shown on the Panel before informing the customer how many orders waiting's just prior to his order. In this case, it can get out if he wants to, if the number of orders is too big for its waiting time.
However, I do not know how many lines my 'Orderingtable' will be 'Orderingtable' because both accumulate lines and data lines until being command to remove. Therefore, I cannot predict how many lines I program the party totals the number of quantity for each line.
Is it possible that I can get the part of the 'quantity' without having to know the number of rows in the database so that I can count the total number of pending orders just by adding up the value of the quantity for each line?
I do not wish to "code" my program by limiting the tables of database for us are going to say, only 50 lines at any time.
Attached below, this is how my database table "Orderingtable" looks at, which will be used to extract the 'Quantity' column so that it can count the total number of orders and be shown/shown on the front panel of my Labview program.
I hope that you are able to help me!
Thank you so much in advance.
See you soon,.
MUI
You can also use the SUM function:
SELECT SUM (Quantity) OF the order WHERE Queue_No = %d
And no need of an "Order By" clause, if you add just the quantities.

Hello
is there a limit to the number of lines, I'm processing in a relationship with apex_application.g_fxx?
I have a report with 7000 lines. My pk_row is apex_item.display_and_save(1,pk_id).
When I want to loop through these lines after submit and access with apex_application.g_fxx, I get the error "page not found".
If I have just 500 lines or 1000, it works.
Please help, it's urgent :-(I'm going to guess it's the parameter maxplsqlparameters for your instance of the Apex.
I had this happens with forms tabular and master / detail where you have a large number of lines or a number high columns resulting in a product that exceeds the value of the parameter (the number of parameters is something like lines * columns more some other small hold there).
By default, this setting is installed in 2000 (so we had some forms had slightly more than 60 rows and columns 30 - ish which would be run against this on submit.)
We have increased this setting to 10000 and so far, so good. We have noticed no ill effects of this. We arrived at this functional entry number based on key end users on the largest number of lines they would probably see at some point in the page.

How to get the number of lines in a region of report
Hi all
Is there a way to get the number of rows returned in a report region, without issuing an another 'select count (*) from une_table?
I mean something like the substitution string #ROW_NUM # but for the total of the lines.
Thank you
Pedro.http://download.Oracle.com/docs/CD/E17556_01/doc/user.40/e15517/UI.htm#CHDDGGEG
For parts of classic report, the footer region supports the following substitution strings:
#ROWS_FETCHED # indicates the number of lines read by the reporting engine Oracle Application Express (the size of the page). You can use these substitution strings to display messages to the user. For example:
Read #ROWS_FETCHED # #TIMING # seconds lines.
* #TOTAL_ROWS # displays the total number of rows that satisfy an SQL query used for a report.
#FIRST_ROW_FETCHED # and #LAST_ROW_FETCHED # show the range of displayed lines. For example:
Until #FIRST_ROW_FETCHED # by #LAST_ROW_FETCHED # of #ROWS_FETCHED # displayed >

How can I find several intersect between the number of lines
Hello
I created the table as below,
CREATE TABLE "TRANS" (NUMBER (9.0) "TIDSET", "ITEM" NUMBER (9.0)); "."
and insert valuse Trans table as below,
insert into values trans (1,1) insert into values trans (1,3) insert into values trans (1.4); insert into values of trans (1.5); insert into trans values (1.6);
insert into values trans (2.1); insert into values trans (2.2); insert into values trans (2, 4); insert into values trans (2,6), trans insert values (3,1);
insert into values trans (3,2) insert into values trans (3.3) insert into values trans (3.6); insert into values trans (1, 2); insert into trans values (1,1);
and now I have to find the intersection between the lines as below,
Select tidset from whose point trans = 1
intersect
Select tidset in the point transwhere = 2
intersect
Select tidset from trans whose point = 3;
If we have 1000 lines there is no way to find the intersect in this way, so I need to write a program to find the intersect as above without inserting the (item = N) manually each time, can you help me with this please?

This is not true. The query you posted will work well for any number of lines. Perhaps you are really worried about the number of distinct values of the point.
so I need to write a program to find the intersect as above without inserting the (item = N) manually each time, can you help me with this please?
In a solution of Ivan, you probably mean "COUNT (DISTINCT point)" rather than "COUNT (*).
In addition, if element values are predictable, you don't have to code in all hard; You can generate, like this:SELECT tidset FROM trans WHERE item IN ( SELECT LEVEL FROM dual CONNECT BY LEVEL <= n ) GROUP BY tidset HAVING COUNT (DISTINCT item) = n ;

Change the number of lines displayed in a report
Hi guys,.
I have a query that will return 3 rows, so I set the number of lines on the screen of the report attributes for 3 and everything was fine.
I then changed the query to return 4 lines and also changed this attribute to 4, but the report stubbornly refuses to display 4 - only 3 old.
Is there something I missed here?

Script to determine the number of lines of text in a paragraph?
I'm revisiting a problem I posted here last summer, thanks to all those who have offered help, but I could not sort it out.
http://forums.Adobe.com/thread/455526?TSTART=0
What I'm after is a 'search' function to insert in a FindChangeByList.
Jongware suggested the following - but when inserted in my list, I can't seem to do anything - it does not take a Javascript error.
app.findTextPreferences = NothingEnum.nothing;
app.findTextPreferences.appliedParagraphStyle = "Callout_3";
foundItems = app.activeDocument.findText();
for (var i=foundItems.length-1; i>=0; i--)
{
if (foundItems[i].paragraphs[0].lines == 2)
foundItems[i].paragraphs[0].appliedParagraphStyle = "Callout_2";
if (foundItems[i].paragraphs[0].lines == 1)
foundItems[i].paragraphs[0].appliedParagraphStyle = "Callout_1";
}I regularly get a 'word' document on which I run a "FindChangeByList" that cleans and formats the text with a number of GREP/text searches.
One of the lines of research converts a particluar to the text string to a paragraph style "Callout_3" (the most common legends).
This style applies to paragraph NET, above and below the line, to create a block/strip of color that says text is reveresed.
The problem I have, is that the style (due to the rules of paragraph), works well if the paragraph has x 3 lines of text.
I have updated styles in place for any eventuality - Callout_1 (for the single line of text), Callout_2 (for x 2 lines of text) etc.
I'm looking for is a script that can count the number of lines in the paragraph (once the "Callout_3" style has been applied) and then change the style accordingly the number of lines in each paragraph/legend.
Any other thoughts?
Steve
-your script can be incorporated into a FindChangeByList .txt file?
No, he needs to access real paragraph finds it to count the number of line of this paragraph. FindChangeByList Find/change regular strings together, and you can not search for a certain number of lines.
-what it takes to go to the 'findStyle ('Callout_1');"reference within a"group of paragraph style"called"legends "?
... Nothing. Because the style can be within a group, I wrote this little function. The findStyle performs a loop on * all * paragraph styles in the document, the root and in each group and returns the first style with the name that you provide in the function call (tested!).
So if there is a 'Callout_1' style anywhere, it should find it... Are you sure you put the name at the top of the script? I've seen in a post later that it is actually called "Callout_1line".

divide the table based on the number of lines
Hello
I am trying to split a table based on the number of lines and then treat.
Say I have a TEST_XXX table that contains 50 lines, what I would do is.
to access multiple lines of 10. How can we achieve this?
What I thought is, once the table is created and the line are filled.
Add a new column to the table and perform a procedure that inserts of 1 to 10 first lines
and 2 to 10 lines and 3 to 10 next ranks... etc. Based on this, that we can treat
the first set of lines then play next or etc...
is there a better way to do it?
Code to create the table:
Code to add lines:CREATE TABLE TEST_XXX ( A_ID VARCHAR2(10), B_ID NUMBER, c_ID VARCHAR2(10), D_ID NUMBER )
The original problem is, I have a huge table, and I write a sql query to process,DECLARE BEGIN FOR I IN 1..50 LOOP INSERT INTO TEST_XXX VALUES('ABCDE',123,'ZYXWV',321); END LOOP; COMMIT; END;
When I treat him by selecting all the values in the table, it is very slow.
But when I have treat small Coulon (say 100 rows), it works very well.
That's how I got the approach described above in mind.You can use NTILE.
