Concatenate the strings of several lines into one line.
HelloWhat is the name of this analytical function (or log in) which
would return more line as a concatenated line strings. that is to say:
(I know that it is possible using the regular functions of pipeline).
ROW1: STR1
ROW2: STR2
ROW3: STR3
select tadah().... from ...
result:
ROW1: STR1 STR2 STR3
Thank you.

The rendering of several clips into one video file?
Hello
I'm completely new Premiere Pro. I decided to make my first video.
Here's what I did. I added my clip to the timeline, then I used the razor tool twice in order to slice clip in 3 small clips. Then I applied basic effects to a small clip in the middle.
So I decided to make the entire images. I put 'In' at the beginning of the first clip and placed 'Out' at the end of the last clip.
After I clicked on "make Sequence - in at Out ' I see that Premiere Pro product 4 videos: three videos of each of those that contains appropriate slice of the original clip and the 4th video seems to contain only 1 image of the original clip:
Here are all the files created during the rendering process:
So, instead of making 4 videos I need first to render the images together in a single clip. Please could you tell me how I can do?
I also tried to select all 3 clips and then made selection, but unfortunately I got the same result as above.
Thank you!
Thank you guys!
Yes, later that day I already understood how do. Nowdays Youtube is a source of all knowledge. I just look for "how this ' and ' how '. Previously, I used Sony Movie Studio 12, but after reinstalling OS on my PC, I decided to try Premiere Pro.
BTW, here is my first video. I spent probably 5 to 6 hours yesterday learning first LOL just to make this clip!

I think it is better the purpose of having a consolidation set. Could you tell me how to consolidate several salary mass as a whole or alternatively can add several wage masses on the fly (as parameters) for each race NACHA?

You don't need the double table much in PL/SQL. You can simply say
v_comp := SUBSTR (p_csa, 1, 4);
Almost all integrated single-row functions work in PL/SQL. (NVL2 is the only one I know who does not work in PL/SQL).
SELECT SUBSTR (p_csa, 5.3) INTO v_csa_prefix FROM DUAL;

GCSIM4DP
If you don't want space, then only concatenate all the spaces in the string before you write it and REPLACE allows you to delete all the spaces that have been copied from p_csa. For example:
UTL_FILE.PUT_LINE ( fileidinvoice , REPLACE ( v_telco || v_comp || v_csa_prefix || v_csa_type , ' ' ) );
I guess you need the v_comp of separate variables, the v_csa_prefix and the v_csa_type for something.
I hope that answers your question.
If this isn't the case, after a complete script that people can run to recreate the problem and test their ideas. Display the results you want (in other words, the contents of the file created).
Always say what version of Oracle you are using (for example, 11.2.0.3.0).

A question about the count of several lines of table in a PL/SQL block
Hi all
I have a problem on counting the rows from several tables in a PL/SQL block, and I would be grateful if you could kindly give me a helping hand. Here's my problem: file in Microsoft Excel (one column) I have a list of several names of tables. For each table, when the number of rows is equal to 10000 I have to call a procedure. Here's how I tried to do:
I already checked this code with tables inividual and it works. The only problem isDECLARE CURSOR tb_cursor IS WITH my_table_names AS ( SELECT 'table1' AS tbname FROM DUAL UNION SELECT 'table2' AS tbname FROM DUAL UNION SELECT 'table3' AS tbname FROM DUAL UNION SELECT 'table4' AS tbname FROM DUAL UNION . . Here I continue writing one line for each table in order . to have the table names stored in my Excel file as a table to be queried by SELECT statement . ) SELECT * FROM my_table_names; BEGIN -- Here I verify that for each table having more than 10000 lines -- I call the specified procedure which is needed FOR I IN tb_cursor LOOP DECLARE -- Here I declare a cursor for counting the number of rows CURSOR currentTableRowCounter IS SELECT COUNT(*) AS rowsNum FROM I.tbname; numberOfRows currentTableRowCounter%ROWTYPE; BEGIN OPEN currentTableRowCounter; FETCH numberOfRows INTO numberOfRows; CLOSE currentTableRowCounter; IF (numberOfRows.rowsNum > 10000) THEN -- And here I will call the procedure which has to be run END IF; END; END LOOP; END; /
Indeed, oracle considers "I.tbname" as an unknown table name (although he refers to by its exact name).. . . SELECT COUNT(*) AS rowsNum FROM I.tbname; . . .
How can I solve this problem? I mean, how to use a variable (in my example, I.tbname) as the table name in the FROM clause to query a table instead of explicitly write the name of the table?SQL> @script.sql FROM I.tbname; * ERROR at line 99: ORA-06550: line 99, column 12: PL/SQL: ORA-00942: table or view does not exist
Thanks in advance,
DariyooshReplace the following code:
DECLARE -- Here I declare a cursor for counting the number of rows CURSOR currentTableRowCounter IS SELECT COUNT(*) AS rowsNum FROM I.tbname; numberOfRows currentTableRowCounter%ROWTYPE; BEGIN OPEN currentTableRowCounter; FETCH numberOfRows INTO numberOfRows; CLOSE currentTableRowCounter; IF (numberOfRows.rowsNum > 10000) THEN -- And here I will call the procedure which has to be run END IF; END;
By the following:
Declare numberOfRows number; begin EXECUTE IMMEDIATE 'select count(*) from '||I.tbname into numberOfRows; IF (numberOfRows.rowsNum > 10000) THEN -- And here I will call the procedure which has to be run END IF; end;

View the information from the related table instead of the ID in several line datablock
Hello
I searched on the web, the forum and the documentation, but I have not found a solution to this problem:
I have two tabs with a relationship of the master / detail of one-to-many. Block detail data shows several lines such that it can be several associations table of mater in the details and I want to display the description of the master data block instead of the field with the ID for each line in the block of retail.
I tried to place an item with the option 'copy value', but then I lose the relationship of master / detail, because that is what forms wih the field id for linking blocks.
Also, I've seen in other posts that I can use a view, but I can't understand how would I update or remove data then.
The only thing that I realized is to the description field in its own datablock in the same tab, a relationship master / detail-detail (or master-detail-master). BTW, I don't think it's beautiful "formulas"programming"and it does too much for my needs."
I guess it must be a trivial thing, but I don't know what to try next. Thanks in advance!
Published by: user10278211 on Sep 17, 2008 20:13AAH, I think now I got your management!
You have 1 Deptno and dname "XYZ" in the master and you want to display:
EmpNo Ename DName 1 User1 XYZ 2 User2 XYZ
-What?
If so:
1 create a new element in the retail block, let's call it DSP_DNAME, set database property to point to 'no '.
2. create a POST-QUERY-Trigger on detail-block with the code: DETAILBLOCKNAME. DSP_DNAME: =: MASTERBLOCKNAME. DNAME;
3. create WHEN-CREATE-RECORD-Trigger with the same code.That's all

===========================================================================================================================
Could please help what is wrong in the code, I followed all the steps as stated in the guide, but the table advance, the problem starts whenever I click on the button Add a new row for the creation of new line.
I couldn't understand what was wrong with the code.
Thanks in advance,
Suman
Suman,
A few points:
1. Why do you call handleCurrencyChangeEvent in the event to add a line? Simply set the useful, likely of the values in the line it himself.
ex:-instead of calling the handleCurrenyChange method, simply add the below lines inside the createDetailRow()
dtlrow.setAttribute ("ExchangeRateTypeRender", Boolean.FALSE);
dtlrow.setAttribute ("ExchangeRateDateRender", Boolean.FALSE);
dtlrow.setAttribute ("ExchangeRateRender", Boolean.FALSE);
2. it looks like you have on the field of the currency and that fireAction handleCurrencyChangeEvent action method is called, right?
Instead of using dtlVo.getCurrentRow, use the code below:
public void handleCurrencyChangeEvent(String eventRowSourceParam) { OAViewObject pvo = (OAViewObject)findViewObject("xxCurrencyPVO1"); OARow row = (OARow)pvo.first(); OAViewObject dtlVO = (OAViewObject)findViewObject("xxEcreditCardDtlVO1"); //OARow dtlRow = (OARow)dtlVO.getCurrentRow(); OARow dtlRow = (OARow)this.findRowByRef(eventRowSourceParam); String currency = (String)dtlRow.getAttribute("CurrencyCode"); // NULL POINTER EXCEPTION if ((currency == null) || ("AED".equals(currency))) { row.setAttribute("ExchangeRateTypeRender", Boolean.FALSE); row.setAttribute("ExchangeRateDateRender", Boolean.FALSE); row.setAttribute("ExchangeRateRender", Boolean.FALSE); } else { row.setAttribute("ExchangeRateTypeRender", Boolean.TRUE); row.setAttribute("ExchangeRateDateRender", Boolean.TRUE); row.setAttribute("ExchangeRateRender", Boolean.TRUE); } }
In the controller:
if((ADD_ROWS_EVENT.equals(event)) && "AdvTblRN".equals(pageContext.getParameter("source")) ) { am.invokeMethod("createDetailRow",null); am.invokeMethod("initPVO"); } //**End Add Row Button** else if ("currCodeChangeEvent".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM))) { String eventRowSourceParam = pageContext.getParameter(EVENT_SOURCE_ROW_REFERENCE); Serializable[] params = {eventRowSourceParam}; Class[] paramTypes = {String.class}; am.invokeMethod("handleCurrencyChangeEvent",params, paramTypes); }
3. Why do you call initPVO when it is clicked on the Add line? Are you calling not just in the PR?
You could call it once in the PR and let. When you call it PR, you may need to remove the handleCurrencyChangeEvent of this method call.
See you soon

Use REGEXP_SUBSTR:
SELECT REGEXP_SUBSTR (str, '[^,]+', 1, 1) AS part_1 , REGEXP_SUBSTR (str, '[^,]+', 1, 2) AS part_2 , REGEXP_SUBSTR (str, '[^,]+', 1, 3) AS part_3 , REGEXP_SUBSTR (str, '[^,]+', 1, 4) AS part_4 FROM table_x ;
Str can contain foul? For example, you can have a string like ' foo, bar ", where you want to count part_2 and part_3 as NULL and 'bar' is part_4? If so:
SELECT RTRIM (REGEXP_SUBSTR (str, '[^,]*,', 1, 1), ',') AS part_1 , RTRIM (REGEXP_SUBSTR (str, '[^,]*,', 1, 2), ',') AS part_2 , RTRIM (REGEXP_SUBSTR (str, '[^,]*,', 1, 3), ',') AS part_3 , LTRIM (REGEXP_SUBSTR (str, ',[^,]*', 1, 3), ',') AS part_4 FROM table_x ;
