Check the syntax of the cursor

Hi all,

I'm no expert of PL/SQL. I have to do an update to a table using a cursor.
I saw a guide on the internet and I have created this script:

Set serveroutput on
DECLARE
REC NŒUD$ % ROWTYPE;
cursor cur is select ID, NODE_ID OF THE NŒUD$;

BEGIN
Open the heart;
loop
News of FETCH in rec;
When the output cur % NOTFOUND;
UPDATE LINK$ SET a.END_NODE_ID = rec. Node_id WHERE a.T_JNCTID = rec.ID;
dbms_output.put_line ('update 1': cur % ROWCOUNT);
UPDATE LINK$ SET a.START_NODE_ID = rec. Node_id WHERE a.F_JNCTID = rec.ID;
dbms_output.put_line ('update 2': cur % ROWCOUNT);
end loop;
close cur;
end;
/
Set serveroutput off
commit;

I'm not sure that the bold line is correct. I don't understand what that means.
Can you help me?

Thank you in advance.

Because the fetch statement fails when you try to store the cursor file in CDR which is ROWTYPE table NŒUD$.
The number of columns in the ROWTYPE variable must be equal to the number of columns in the CURSOR. So if the NŒUD$ table has more than two columns your extraction will fail.

See the example below:

SQL> declare
  2  my_tab emp%rowtype;
  3  cursor c1 is select empid from emp; -- I select only one column here and it fails
  4  begin
  5  open c1;
  6  fetch c1 into my_tab;
  7  close c1;
  8  end;
  9  /
fetch c1 into my_tab;
*
ERROR at line 6:
ORA-06550: line 6, column 1:
PLS-00394: wrong number of values in the INTO list of a FETCH statement
ORA-06550: line 6, column 1:
PL/SQL: SQL Statement ignored

SQL> ed
Wrote file afiedt.buf

  1  declare
  2  my_tab emp%rowtype;
  3  cursor c1 is select * from emp; -- I select all columns from emp table and it works fine
  4  begin
  5  open c1;
  6  fetch c1 into my_tab;
  7  close c1;
  8* end;

    I solved the problem. It is apparently caused by minGW installed with 14.4 vivado which does not work with windows 8. So, I replaced the minGW on vivado record 14.4 with the latest version of minGW.

    I'm developing an interactive form. Last week, when I open the form to start working on it, I saw a button on the STANDARD toolbar with a lable control SYNTAX without count as him "check spelling", buttons Zoom etc. But, when I opened today, the button CHECK SYNTAX is diappeared.

  • Reposition the cursor when the check box is selected

    Good day all.

    I'm trying to figure out how I can reposition the cursor in a text field once I've selected a checkbox.

    Example; I have 3 boxes can select use. When the user selects the check box, I want to cursor to move to this box.

    Does anyone know how this could be done?

    Using Adobe LifeCycle Designer 8.0

    Windows XP Pro

    Thank you all

    Chomp

    No Chomp problem, I updated the form that you posted to set focus in the first textfield in the hidden subform (criterion 1). I published the form here:

    https://Acrobat.com/#d=46bhrRPpzUOEN4XI7--W-w

    Notice how the full path should be clearly explained when fields bound, in this case, a check box and a text field, are in different subforms.

    If you never do know what the full path to a field, click a different field, click in the script Manager window, then ctrl + click the field you want the path. If you have this selected field ctrl + click 'this' will return just as he will himself reference in the script manager.

  • Checking the status of block to a block so the cursor is in a block of diiferent

    Hey guys,.
    I'm sure many of us have encountered this situation before. I have 2 different blocks (B1 and B2) in my form. Block B1 is a single record block while B2 block is a block of several record. I noticed that when I update an existing record in my block B2, something has changed in my block B1. I don't know what changed, but the status of block B1 = "CHANGED". There's a trigger when a validation in one of block B2 elements. Now, if I insert a new record into the block B2, then nothing changes in the B1 block.

    Now, there is nothing very obvious which seems to be updated to block B1. So I'm trying to understand when block B1 status changes to REQUEST to CHANGE because I can't really block B1 navigate When-Validate_item to check the status of the block. I'll try with Next-key to see if nothing changes in the B1 block in the meantime.

    So, I moved the WVI key-Next-Item trigger and made a Go_Block ('B1') and printed the status of block B1 and has "CHANGED". I printed the lock status on the first line of key-Next-item proving that nothing in KNI has changed the State of the B1 blocking. So I have some block-level triggers such as:
    WHEN-NEW-BLOCK-INSTANCE
    WHEN-VALIDATE-RECORD
    PRE-QUERY
    POST-QUERY
    ON-LOCK
    ON-UPDATE
    ON-DELETE
    ON-INSERT
    PRE-RECORD
    WHEN-NEW-RECORD-INSTANCE
    Any ideas?

    Thank you

    Published by: RDonASnowyDay on March 15, 2010 11:27

    If it happens only for existing records and not for new, I'd vote for the POST QUERY relaxation. As you only have a few triggers I would try to eliminate them one by one and check when it starts to work.

  • How to assign values to the current element where the cursor is?

    Hi all

    I have a block of "tabular" data, B_Emp (from the Employee table) and the other non-database & non tabular block consisting of a text_items B_Test.

    'Emp_id' is one of the column in the Employee table and I want to attribute all the values of the Emp_id in all text_items of the B_Test in order, when you press a particular key.

    Here's what I wrote in the trigger

    Declare

    i the number;

    number of l_last_record;

    next varchar2 (40); -to hold the values of cursor system of the next item in the block of B_Test

    next_r varchar2 (40); -to hold the values of cursor system of the next record in the block of B_Emp

    Begin

    go_block ('B_Emp');

    Set_Block_Property ('B_EMPLOYEES_ALL', DEFAULT_WHERE, "Emp_id is not null");

    execute_query (no_validate);

    last_record;

    l_last_record: =: system.cursor_record;

    premier_enregistrement;

    next_r: =: SYSTEM. CURSOR_ITEM;

    go_block ('B_Test');

    Next: =: SYSTEM. CURSOR_ITEM;

    because me in 1.l_last_record

    Loop

    go_item (Next);

    : next: =: B_Emp.Emp_id;-here is the problem

    next_item;

    Next: =: SYSTEM. CURSOR_ITEM;

    go_item (next_r);

    next_record;

    next_r: =: SYSTEM. CURSOR_ITEM;

    WHEN THE OUTPUT: SYSTEM. LAST_RECORD = "TRUE";

    End loop;

    End;

    Now, this gives me the expected bad Bind Variable error as there is no block of data with the name "next".

    However, I checked the value of 'next' and 'next_r' (message (' value = ' | next)) and I'm getting the expected values.

    So if somewhere, I am able to put my value in the current item the cursor (because at the beginning of the loop, my cursor system is exactly to the text element where I need to insert the value) so I did not have to use this " : next: =: B_Emp.Emp_id;"

    OR

    If somewhere, I am able to return the items in my B_test block dynamically so I can simply use

    Loop

    ": B_test." dynamic reference for the element ": = : B_Emp.Emp_id;

    next_record;

    WHEN THE OUTPUT: SYSTEM. LAST_RECORD = "TRUE";



    Please help me out of this!

    Guy! I found a solution for the same thing.

    We can use integrated a 'copy' to set the values of the element where currently is cursor system.

    The syntax will be

    Copy ((new_value): System.Cursor_Item);

    -where new_value is the variable that contains the data to be assigned.

    In addition, we can assign the values from the system cursor to any variable.

    The syntax will be '

    new_value: =: System.Cursor_Value;

    Thanks a lot guys for your help and concern

    See you soon!

  • Function of the cursor

    Dear all,

    I got a general question about the features of a cursor.

    I got a slider that has multiple where conditions such as

    CURSOR C_EMP(p_empno NUMBER, P_ename in varchar2) IS SELECT EMPNO, ENAME FROM EMP WHERE EMPNO is P_EMPNO AND ENAME = P_ENAME;

    Suppose I spent where different conditions at this cursor, ORACLE doesn't all the features like PARSING, SYNTAX as a Where condition checking etc is evolving (GOLD) Oracle will bind the values during the execution of the cursor so that it is PARSED but EXECUTED MULTIPLE times.


    Receive your answer on that.

    Thank you
    MK.

    Hi Maddy,

    Cursor is a district of merory where is the analysis of the SQl statement.

    If you change a condition surely new analysis view will be.

    CURSOR C_EMP(p_empno NUMBER, P_ename in varchar2) IS SELECT EMPNO, ENAME FROM EMP WHERE EMPNO = P_EMPNO AND > ENAME = P_ENAME;
    CURSOR C_EMP(p_empno NUMBER, P_ename in varchar2) IS SELECT EMPNO, ENAME FROM EMP WHERE EMPNO = P_EMPNO AND > ENAME = P_ENAME and (other condition);

    the two above statements are different from each other that so surely a new analysis view will be.

    But if you use bind variables in the sliders, then no new analysis in view will be, it will be just exceute...
