Problem with a declare statement

Hello

I don't get the right output by using the code below. Can you please help?

declare
number of v_aer1;
number of v_var1;
number of v_var2;
cursor c1 is
Select a.aer_id, a.seq_text in v_aer1, aer_text v_var1 an a.FIELD_ID WHERE the = 101506 and aer_id group 103000005274 by a.seq_text, a.aer_id, rowid = rowid in
(select min (rowid) in the aer_text where FIELD_ID = 101506 and aer_id = a.aer_id);
Start
I'm in c1
loop
For J in (select min (seq_text) in the v_var2 of aer_text where FIELD_ID = 101506 and aer_id = 103000005274)
loop
If v_var1! = v_var2 then
insert into test_today values (v_aer1, v_var1);
end if;
end loop;
end loop;
Exception when others then
Dbms_Output.put_line (' error ' |) SQLERRM);
End;

If you have any questions please let me know.

Thank you

Leaving aside the intent of the code, which could certainly be done with a single INSERT statement, if I understand what you're doing, the variables you declare and use in cursor statements are not actually met.

SQL> declare
  2     l_v number;
  3     cursor c1 is
  4        select 1 col into l_v from dual;
  5  begin
  6     for i in c1 loop
  7        dbms_output.put_line('Col is: '||l_v);
  8     end loop;
  9  end;
 10  /
Col is:

PL/SQL procedure successfully completed.

When you use a loop of implicit cursor like this, you need to refer to the record of cursor that is created for you. So, your code should look similar to this point is syntactically correct and at least semi-utile.

declare
   cursor c1 is
      select a.aer_id, a.seq_text
      from aer_text a
      WHERE a.FIELD_ID = 101506 and
            aer_id = 103000005274
      group by a.seq_text, a.aer_id, rowid
      having rowid in (select min(rowid) from aer_text
                       where FIELD_ID = 101506 and
                             aer_id = a.aer_id);
begin
   for i in c1 loop
      For J In (select min(seq_text)
                from aer_text
                where FIELD_ID = 101506 and aer_id = 103000005274) loop
         if i.seq_text != j.seq_text then
            insert into test_today values(i.aer_id, i.seq_text);
         end if;
      end loop;
   end loop;
End;

I was really very surprised to find that the in the variable bits in your cursor definitions do not throw an error in compiling.

Problem with variable declaration

I'm developing a multiuser Flash application, using the smartfox Server 2.0, but I'll have a problem with defining/declaration of a variable/object/table and then access. I am trying to set the "curMap" (be it a variable, the matrix, the object, everything that works) within the following function, like the array returned by the server, "resObj". It works fine as long as I only call 'curMap' within this function (see you in line: r_txt.text = curMap ;)) However whenever I try to call the "curMap" on the coding of the image outside the function, it returns under the indefinite form or usually nothing. Any ideas on how to properly / attribute this? I tried various things (such as _root, _global or setting the var "curMap" outside of the function) with no luck.
Here is my Code:
smartfox.onExtensionResponse = function (resObj:Object, type: String)
{
If (type is 'xml')
{
If (resObj._cmd is "getMap")
{
curMap = resObj.db [0];
r_txt. Text = curMap;
} Else if (resObj._cmd == "getSurr") {}
surrMap = resObj.db;
b_txt. Text = surrMap [0];
}
}
}
Thank you

Make sure that you are trying to access this variable before it is defined. That is to say, which resembles an asynchronous function for the code of this function will probably run AFTER the code that appears in the lines that follow the body of the function.

It's driving me crazy!

Syntax error (missing operator) in query expression ' US_Dealers.ID EQ DealerID

You accidentally use the CF equals operator: "EQ".

Instead of MS Access: «=»

in a query expression. AND SaleDate BETWEEN #10/1/2009 #-October 18, 2009 #'.

I don't see how CreateODBCDate() would produce these values. But maybe it's just a quirk of the error message?

You don't need to declare a constructor for "all" attributes - you get one automatically. Remove the declaration of the complete constructor function on all 3 attributes, and you will find your block works fine dbms_outputs.

Specific problem with pimples and States

Hello
I firstly apologize for use Google Translate :-(
I have a problem with InDesign does not resolve. That's a digital publication.
My goal is:
A 'Gallery' button and the image of the ball appears with three buttons: "Previous Image", "Next Image" and "narrow Gallery.
I don't want the Gallery either visible, or buttons that control, until the 'Gallery' button, so I think that all the buttons except 'Gallery' by selecting the option 'hidden until this active'.
I want the gallery and the buttons that control, disappears when I press the "Close Gallery" button.
What I call 'Gallery' is an image that fills the screen.
After you have placed the image on your site have become the button property "Hidden until this that active."
Then convert this key in order to several States (what I will call 'button States') and by successive Governments with the pictures I want to show in the gallery.
I think that the interactions between the buttons.
When the 'Gallery' button I attribute the following "I click on the '.
-"Go to the State."
-Hide the "Gallery".
-Show 'narrow Gallery.
-Show "previous image".
-Show "next image".
-Show "States of the button.
"Previous Image" and "Next Image" buttons are assigned, respectively, to go to the previous state and go to the next State.
When "Close Gallery" button I attribute the following "I click on the '.
-Show "Gallery."
-Hide 'narrow Gallery.
-Hide "previous image".
-Hide "next image".
-Show "States of the button.
"Previous Image" and "Next Image" buttons are assigned, respectively, to go to the previous state and go to the next State.
When "Close Gallery" button I attribute the following "I click on the '.
-Show "Gallery."
-Hide 'narrow Gallery.
-Hide "previous image".
-Hide "next image".
-Hide the "States of the button.
I put it to the top and works correctly until I press "close". Then I hide buttons "Close Gallery", "previous image" and "next image" but it keeps me visible "Button States" showing the last image that was shown.
Don't know how to solve this problem, and I'm going crazy!
Please can someone help me?
Maybe the solution is another approach, but without using "Folio overlays.
Thank you very much.

I moved your post to the DPS forum.

I'm afraid of how you do this will not work with DPS.

This should all be done with a multi state object. The first State would contain anything other than a button to access the first State. After that, set up each State with the appropriate buttons. Without seeing the file, it's a little hard for me to imagine exactly what you want to do.

Problem with 'if - ElseIf' statement with the mouse, click.

I'm having a problem with the code IF ELSE use with a mouse click. I want whenever a user 'clicks' I want to run a particular block of code, up to 3 clicks, then nothing. I tried var meter click local and global but can't seem to cross the first '' if. '' That's what I have now (I use console.log () to keep track.
Ready model I create a global var...
Enter the code to run when the composition is fully charged here
sym.getComposition () .getStage () .setVariable ('clickcnt', 1); //Set 1 meter
var i = sym.getComposition () .getStage () .getVariable ('clickcnt');
Console.log ("count starts at"+ i ");

on the stage, I create an event 'click '...
Insert the code for the mouse, click here
var i = (sym.getComposition () .getStage () .getVariable ('clickcnt');)
If (i = 1) {}
Console.log ("counter is =" + i);
c code
sym.getComposition () .getStage () .setVariable ('clickcnt', 2); //Set against 2
}
ElseIf (i = 2) {}
Console.log ("counter is =" + i);
c code

c code

}
else { //I'm using it to deny any additional clicks.} I don't know there is a good way to do this. I don't know him
SYM. Stop (1000);
Console.log ("End");

I when I run this it never happened the first if it's like the 'clickcnt' var is not getting updated or read correctly.

Problems with my timed State machien

Hi all

The project

I'm trying to create a timed state machine that can scroll through a series of cooling-then-heating cycles, where every cold or heat function occurs during a specific period of time.
For example, if I set the number of cycles to 20 cycles 'cool-then-heat', with a cool cycle lasts 10 seconds and a cycle of prolonged heat of 10 seconds, the program will run for 400 seconds and then stops.

After initialization, a clock will start. In the cool loop, there will be a cool clock which is compared to all of the cool cycle time. If they are equal, continuous cooling, noto, if they are equal the progresses of program in a heat cycle.

The cycle has estrogen to a clock of heat that will be compared to the heat set duration of the cycle. If hot clocks are not equal, heating continues, if they are equal the cycle estrogen is complete and the product is finished or running in another round of cool.

Another round of cool is selected if the elapsed time (since the State apparatus has been initialized) matches both total managed program (i.e. the total length = 400 seconds).

(I've also attached a drawing that explains the process I want schematically the state machine).

The problem

I have a few, but the first is I think I use the block of bad timing - in my VI, the clock of the tick is not starting from scratch when I press run. It is included in a while loop as I have reason to think it will be easier to run (for the computer) if I put a delay (without delay the state machine functions). Rather than from

I have a small calculator that determines how long will be the run time in total (this value is compared to the length of time since the entry into force).

If anyone no matter what other tasks that help sadjusting need me know - I'm very new to labview and want to pick up good practices on the way!

There is also the express VI "out of time", you could use.

Problem with insert/update statements on the MS Access database

Hi all

Before posting this question, I did a search and found this thread.

I have the same problem as pawel had (in this thread), i.e. cannot insert or update data in the Access database. However, the reason is not that I am using some keywords in my domain name - it has been several years using SQL, some things are 'unwritten' rules But this is the first time I try something in LV

However, after losing all day for work that I expect to do the same morning in 1 hour, try many different options and debugging until the level low in the Toolbox of data base screw (building or higher), I saw some weird SQL statement being trained in-house - so I tried what Troy has tried.

"password" is a reserved word in the Jet. I just looked at MOManagers_M, but by changing the field "password" to 'passworda', it does the job.

Problems with the switch statement

There everyone,
I tried to build a page with 4 buttons. Each button is a symbol that contains 2 png´2 who are the drawings of the key. If you click on the button 1, he has to move on the screen. If you click it again it should back off. and if you click on another button button1 is active then button1 should return to the starting position and button 2 should come on the screen.
I use a switch statement and a variable.
composition ready, I used
sym.setVariable("current","");
to set the Variable
each button (one of the png within the symbols), I used:
var = sym.getComposition.getStage.getVariable ("current") courses;
switch (current)
{
case ' ':
SYM. Play ("in");
break;
case button1:
SYM. Play ("out");
break;
by default:
sym.getComposition.getStage.getSymbol (current) ("out") .play;
SYM. Play ("in");
break;
}
announcement each animation buttons are labels for the entrance and animation. There are also triggers that change the current variable on the stage
sym.getComposition.getStage.setVariable ("current", "button1");
If I test inside a browser and click the button nothing happens.
I m what do not know my mistake.
can someone help me?

Problem with analysis - union statement
Hi all

I have an analysis where I use the union statement. I have 4 columns in the result and 4 columns in select statements.
Each select statement is a single equipped with filters.
The results are presented in two rows. In my understanding it #of of columns and type paired in the union statement, I should get 1 row of results (summary of the two).

How can I check in BI which is the cause two appear in two lines instead of 1?

Thank you.

Problem with button 'Over' State

I am just learning flash. I created a rectagle and converted to a button symbol. I got it so that it changes color when someone will find their mouse over it. However, I need the text there, too. My problem is that the symbol comes back to its original color when the mouse is over the text. I tried to make the text in the symbol, and I also tried to put above the symbol on the stage.
I need the rectangel to stay in his "Over" State even when the mouse is over the text. Is this possible?

In the properties panel, make sure that the TextField is not defined to be selectable. There is an icon it for this property activation or deactivation.

Insert into XX_TEST1 (INVOICE_ID,LINE_GROUP_NUMBER,LINE_TYPE_LOOKUP_CODE,LINE_NUMBER) values (131549,25,'TAX',null);

So, if we want to MERGE this table and update the lines with below:

merge into xx_test1 DST
         USING (SELECT  LINE_GROUP_NUMBER,
              LINE_TYPE_LOOKUP_CODE,
              ROW_NUMBER() over(order by LINE_TYPE_LOOKUP_CODE, LINE_GROUP_NUMBER) as LINE_NUM
         from xx_test1
        where INVOICE_ID = 131549
       
             ) SRC
      ON (DST.LINE_GROUP_NUMBER = SRC.LINE_GROUP_NUMBER AND dst.LINE_TYPE_LOOKUP_CODE = src.LINE_TYPE_LOOKUP_CODE AND dst.invoice_id = 131549 )
      WHEN MATCHED THEN
         update
            set DST.LINE_NUMBER = SRC.LINE_NUM
            ;

I get an error message:

SQL error: ORA-30926: failed to get a stable set of rows in the source tables

30926 00000 - "impossible to get a stable set of rows in the source tables.

* Cause: A stable set of rows could not be achieved due to the large dml

activity or one not deterministic where clause.

* Action: Remove any non deterministic of the clauses and reissue of the dml.

I don't know why I'm getting this. Any ideas?

whenever I have this error I convert my fusion in a select to see what is duplication

select dst.LINE_GROUP_NUMBER, dst.LINE_TYPE_LOOKUP_CODE, count(*)
from xx_test1 DST
join (SELECT  LINE_GROUP_NUMBER,
              LINE_TYPE_LOOKUP_CODE,
              ROW_NUMBER() over(order by LINE_TYPE_LOOKUP_CODE, LINE_GROUP_NUMBER) as LINE_NUM
         from xx_test1
        where INVOICE_ID = 131549
     ) SRC
 ON (DST.LINE_GROUP_NUMBER = SRC.LINE_GROUP_NUMBER AND dst.LINE_TYPE_LOOKUP_CODE = src.LINE_TYPE_LOOKUP_CODE AND dst.invoice_id = 131549 )
group by dst.LINE_GROUP_NUMBER, dst.LINE_TYPE_LOOKUP_CODE
having count(*) > 1

you have 2 dst. LINE_GROUP_NUMBER, summer time. Combination of LINE_TYPE_LOOKUP_CODE this duplication.

Problem with a prepared statement

Hi all

I'm trying to insert a row in a database using a statement prepared as follows

String [] test = tester; for(int i = 0; i < employ.length; i++){ System.out.println(test); } String query = "insert into testing values(?,?,?,?,?,?,?,?,?,?,?,?)"; PreparedStatement ps = null; try{ ps = con.prepareStatement(query); if(connected){ for(int i = 0; i < test.length; i++){ String val = test[i]; ps.setString(1, val); ps.executeUpdate(); } } }catch(SQLException se){ displayErrors(se); }

Yet when I try to insert using this code I get a SQL exception SQL Exception: No value specified for parameter 2 I am not entering null's as that first for loop is to check and print out the contents of the array to the console to check for that. All the information is in the array, so I guess my question is how is there no value for parameter 2 when the array is full?

The SQL Exception: No value specified for parameter 2

I am not entered null value because this first loop must check and print the content of the table on the console to verify that. All the information is in the table, so I guess my question is how is there no value for parameter 2 when the table is full?

Because (1) you never set just the first parameter (2) don't you really want to run the PS each time through the loop? Isn't it? I have not guessed not.

problems with an if statement
well, here it is guys: function popLoop (popArray, tracerArray) {}
for (n = 0; n < popArray.length; n ++) {}
trace (popArray.Length);
trace (n);
If (n = popArray.length) {}
trace("sure");
}
}
}

popArray.length = 3 FYI

So whats happening is I want the statement to execute via "popArray.length" [3] times.
the loop contains commands to duplicate movies, but the thing is it stops after the end if statement.

Anyone know why the if statement stops the loop for?
use the double equal (==) to test for equality.
