How to increment the index of row/column in multi-column listbox

Hello

I developed a program in which the multicolumn list box values are read and forwarded to another mechanism. To read specific values in the list box, I used index table to retrieve the value of a particular cell to the instrument.

Allows, for example if I want to run the VI several times and I want to increment the line index whenever the tracks VI as well as for successive runs, the values of the next level of lines are read.

For example. I have the following listbox

HAD Vd Vg

1 0.3 0.2

2 0.4 0.6

So for the first round, based on the index which I note the listbox can read 0.2 and 0.3 and assume that if I run this VI for lets say 2 times during the 2nd time it should read 0.4 and 0.6 instead of 0.2 and 0.3.Is it is it possible to increment the line/column index automatically? Please help me because this is the last step of my project.

Thank you

Robin

Your VI runs millions of times per second and elements within nanoseconds. You need to prevent this.

Here is a quick modification that goes to the next line, every time that you run the VI again and again when he's run out of items.

It might give you some ideas...

How to disable the index to the rows of the table updated

Hello world

I have a problem on a table with Oracle11g.

I would update a table a lines opposite two in a table. This table has an index, and during the inversion, the index is duplicated.

So, I turn off the index and then rebuild all indexes like this: How to disable the index in oracle

However, I can't update a table when my index finger is rolled unusable.

I create my table:

CREATE  TABLE MY_TABLE(
  ID                         NUMBER(5) NOT NULL,
  TYPE                        NUMBER(1) NOT NULL,
  PRIO                       NUMBER(4) NOT NULL,
  CONSTRAINT PK_MY_TABLE
    PRIMARY KEY (ID, TYPE )
);

CREATE INDEX  PRIO_UK
    ON MY_TABLE(TYPE, PRIO);

Then I selected all the elements and the results is:

ID	Type	Prio
1	1	10
2	1	11

Then, I tried to update this list with this script:

UPDATE MY_TABLE set PRIO = 11 WHERE ID = 1 AND TYPE = 1;
UPDATE MY_TABLE set PRIO = 10 WHERE ID = 2 AND TYPE = 1;

I have an error on the first line, because the subscript for type 1 and 11 priority already exist.

You have another solution to solve my problem?

I thank you very much.

Do not disable your index. Just perform your update with a single blow. Like this

SQL> select *
  2    from my_table;

        ID       TYPE       PRIO
---------- ---------- ----------
         1          1         10
         2          1         11

SQL> update my_table
  2     set prio = case when id = 1 and type = 1 then 11
  3                     when id = 2 and type = 1 then 10
  4                end
  5   where (id = 1 and type = 1)
  6      or (id = 2 and type = 1);

2 rows updated.

SQL> select *
  2    from my_table;

        ID       TYPE       PRIO
---------- ---------- ----------
         1          1         11
         2          1         10

How to get the number of rows and columns in Exel file data using Excel report?

Since you have posted this question in the forum of LabWindows/CVI, I guess you want to know how to do with CVI.

You need to know how to open and activate the Excel data file.

How to determine the index of an item in a cluster?

I have a small program that I put in place, as I'm just trying to get up to speed on Labview. I have a boolean cluster buttons and for some reason the top button of the page is coming through as Index 3. There are four buttons in the cluster, but for some reason, there has been a change. The top must be Index 0. How to do the things fixed? I do not see how to determine the index of each button through properties.

Thank you

The order of items in a cluster is the same as the order that you added them. To change the order, just right click and select "rearrange controls in the group. If you use Unbundle by name, you don't care the order.

display the data in row columns

I looked through the previous posts, but it is impossible to find a solution to my problem.

I want to display the data in row columns.
I have shown in the table below and test data and the sql code that gives me the result desired.
However, you can see that the sql depends of me knowing all the values in the column "rank".
I want a way to produce the output without knowing the values of rank.

CREATE TABLE test1 (
  accno       NUMBER,
  holder_type VARCHAR2(10),
  rank        NUMBER)

INSERT INTO test1 VALUES (1, 'acr', 0);
INSERT INTO test1 VALUES (1, 'bws', 1);
INSERT INTO test1 VALUES (1, 'aaa', 2);
INSERT INTO test1 VALUES (2, 'cds', 0);
INSERT INTO test1 VALUES (2, 'xxx', 1);
INSERT INTO test1 VALUES (3, 'fgc', 0);
INSERT INTO test1 VALUES (4, 'hgv', 0);
INSERT INTO test1 VALUES (4, 'bws', 1);
INSERT INTO test1 VALUES (4, 'qas', 2);
INSERT INTO test1 VALUES (4, 'aws', 3);

Here's the required output:=
ACCNO     ALLCODES
1     acr bws aaa
2     cds xxx
3     fgc
4     hgv bws qas aws

I.E. for each accno display the holder_types in rank sequence.

SELECT * FROM
(SELECT 
       a0.accno,
       a0.holder_type || DECODE(a1.holder_type, NULL, NULL, ' ') ||
       a1.holder_type || DECODE(a2.holder_type, NULL, NULL, ' ') ||
       a2.holder_type || DECODE(a3.holder_type, NULL, NULL, ' ') ||
       a3.holder_type || DECODE(a4.holder_type, NULL, NULL, ' ') ||
       a4.holder_type allcodes
  FROM (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 0) a0,
       (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 1) a1,
       (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 2) a2,
       (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 3) a3,
       (SELECT accno,
               holder_type,
               rank
          FROM test1
         WHERE rank = 4) a4
 WHERE a0.accno = a1.accno(+)
   AND a0.accno = a2.accno(+)
   AND a0.accno = a3.accno(+)
   AND a0.accno = a4.accno(+)) a
   ORDER BY accno

A few quick hits.

You can merge the two for loops

You have not need one of the constants 1 and 2 in the index table. They will solve automatically when you expand on the index picture, once you have wired to 0 in the column index.

It seems a lot of handling additional table spent unnecessarily.

See below. I did not try to duplicate your code to see how it actually works, but I believe that I have attached will give the same result with less steps.

How to create the index suitable for my xml...

Hi all... I have an xml attachment saved in an XMLType column in a table that is stored in binary xml secure.
I want to use XQuery to navigate the xml code and push the results in a normal table.

All of this works, I have a question if all the xmlindex I want to create.
I want to create a xmlindex so that the plan of the explain command would be cheaper.
If I remove the where XQuery bit the explain command comes with a cost of 32, but if I use the where the bits of the cost are 223000!
Removal of the index makes no difference if the index is not used here.

What index to use here and especially how he specify?
I read something on the structured and unstructured indexes, but I did not understand what and how to use them.

If someone could help that would be great.

A point, however: the xml used for the explain command is much longer; It contains 48385 lines instead of the rows listed here.
Ad al of them would make the post a little longer...

table and index:

How to check the Index is in harmony with the Table
Hi, DBAS,.

OS = RHEL 4
DB = 10.2.0.4

How do synchronize us the indexes on a table? Can synchronize us a clue? If an index is not having the same number of records in the table?

Thank you
Hari
In fact, I see a different number of rows in table and an index on it.

Select count (asset_id) in the rpt.vehicle; -table
-Returns 23 345 lines

Select count (1) in the rpt.vehicle_idx; -index
-Returns 18 287 lines.

You cannot select an index in this way so it is nonsense.

If you really do:
```
select count(1) from rpt.vehicle_idx;
```
then VEHICLE_IDX is not an index.
```
SELECT object_name, object_type FROM ALL_OBJECTS WHERE OWNER = 'RPT' AND OBJECT_NAME IN ('VEHICLE','VEHICLE_IDX')
```
