• Read the data in the first column selected in a multicolumn listbox

  When a line is selected in a ListBox multicolumn (1 point), how can I go on reading the data in the first column?

  

  The listbox multicolumn itself is the digital picture data type. If you have allowed only 1 point selection and selection mode select any row, it returns the line number. The property node 'Element names' to return a table 2d-chains of the elements in your Inbox. The index of the row to the value of the listbox and column 0. See code attached.

• Registration of image data to text - multi-column file

  Hello

  I'm currently grabbing images using functions IMAQ and am averaging of each image through the columns using IMAQ LinearAverages.vi. I am currently saving these values (IE a size of profile line 1: n) to a text file. However, I have a large amount of images (M) to capture, so I would like to display each image line profile data to an individual column.

  At the moment the text file captures all of the data, but in a single column, not very useful for the purposes of post-processing. Can someone suggest a nice way to do this? Records in a spreadsheet file better?

  I would appreciate any advice.

  Kind regards

• Impossible to extract the data of an additional column in the table advance

  Hello

  We have an obligation to add an extra column to the table of advanced search. In addition, we need sort the table using this additional column.

  Now, we have achieved the following:

  1. the required VO was already extended previously and the additional column (LAST_UPDATE_DATE) is already present in the definition of the EO. So, we just added the tag for LAST_UPDATE_DATE in YOUR XML in the form:

  < ViewAttribute

  Name = "LAST_UPDATE_DATE".

  IsPersistent = "false".

  Type = "Oracle.jbo.domain.date"

  ColumnType = "DATE".

  AliasName = 'LAST_UPDATE_DATE. '

  Expression = "LAST_UPDATE_DATE."

  SQLType = 'DATE' >

  < / ViewAttribute >

  2 added a new MessageStyledText column, and updated the following property:

  Prompt = LastUpdateDate. Discover the Instance = TaskPerzSumVO. Display attribute = LAST_UPDATE_DATE. Sort Allowed = true

  The field is now visible in table advance and whenever we seek, attaches the value as ' 1901-01-01'. While I checked manually in the respective table, we have the appropriate data. But in the front end we do not get the data in our additional column of table in advance. In addition, if we try to sort the table by clicking the column LAST_UPDATE_DATE, we get the NPE error. Spec of NullPointerException is as follows:

  # # 0 in detail

  1. java.lang.NullPointerException

  at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:989)

  Kindly help us to obtain the appropriate data in the additional column. Thank you!

  Kind regards

  Zahid

  Hi Zahid,

  This is the error:

  29000: unexpected exception caught: oracle.jbo.NoObjException, msg = Houston-25003: TaskEO.LAST_UPDATE_DATE object of type entity activity not found

  Tag entity by its use should have only name of EO and not the name of the attribute.

  Use instead under the tag:

  EntityUsage = "TaskEO".

  Also, I mentioned that rather tags manually, add it please try Wizard VO to add this attribute in EO attributes available list.

• Change data type for the column in a table - Oracle 8i

  Team,
  
  I need to change a VARCHAR2 column in number.
  
  ALTER table xyz change number abc;
  
  By giving the above statement, it says I need empty this column before you change.
  
  I can't change the data type before emptying this column.
  
  Please indicate any other solution. Give me some suggestions.
  
  Empty the column for me here BIG task.

  user11081688 wrote:

  Not according to the documentation:

  You can change the data type of any column or decrease the size of the entire column if all rows in the column contains NULL values.

  Please indicate any other solution. Give me some suggestions.

  You can add another column with the correct data type.

  ALTER TABLE xyz ADD COLUMN def NUMBER;
  UPDATE TABLE xyz SET def = TO_NUMBER(abc);
  ALTER TABLE xyz DROP COLUMN abc;
  ALTER TABLE xyz ADD COLUMN abc NUMBER;
  UPDATE TABLE xyz SET abc = def;
  ALTER TABEL xyz DROP COLUMN xyz;
  

  If I remember correctly, Oracle 8i does not support the change of name of column if this solution is a bit more complicated than 9i and above. Another option would be to create a new table with CREATE TABLE AS... SELECT, drop the old one and rename a new one to the old.

• How to recover the data type of a column in a table?

  Hello
  
  I want to retrieve the data type of a column in a table. At the moment I'm querying attribute 'OCI_ATTR_DATA_TYPE', but it is SQLT_CHR varchar2 and nvarchar2 data type columns. I need to make a distinction between these columns of two separate data types. Y at - it all API through which I could get the exact data type of a column, i.e. "nvarchar2?
  
  Thanks in advance.
  
  Hashim

  Hello

  It is not a very direct way to do it. What you can do is to call OCIDescribeAny on the table that you want to get information. You can then get the OCI_ATTR_CHARSET_FORM attribute for the column. If the value of the attribute that you get is SQLCS_IMPLICIT, that would mean its a varchar/char/varchar2 column regular. If you get SQLCS_NCHAR, this means that the column is NCHAR. You can get the example of it here:

  http://download.Oracle.com/docs/CD/B14117_01/AppDev.101/b10779/oci06des.htm#446491

  Just look for the section "Recovering for a Table column Datatypes".

  Thank you

For example: the format would, however, on September 1, 2009, I can write 01/09/09 and he would be converted automatically for September 1, 2009. Save me time.

  Select the column, and then open cell formatter:

  Hey thanks for the sponsor and the first off I must apologize for the State, I am attaching my VI. I put the part of the VI that I am working on (my team has access, so didn't post everything here) and also attached the data file (when just written in a spreadsheet file, not through the attached VI). I want to convert the long row of data and then start a new column every 50, 100, 5 points (user-defined).

  Using the data from the file, you can reshape everything simply (as you already!), followed by transposition (since you want columns instead of rows). 2D arrays must always be rectangular, so the last column is filled with zeros if necessary. Is that what you want?

  

  Of course if you try to add a new column in a file, that will not work. You can only add lines in an existing file because of the way the data is organized. To add columns, the entire file must be read, intertwined and all re-written new data in the file.
