How to filter a column of values?

Hello

I imported a .csv file large journal that contains many different columns and values in DIAdem. One of the columns contains a hexadecimal value field, and I need to filter the column by the last byte of this hexagonal field. For example, one of the values can be "CFFD0F3" and I need to find all the rows that have "F3" as the last byte. I also need all the other columns to filter the same way.

There seems to be an easy way to do this in DIAdem, and I searched online and via the discussion forums of the means to accomplish it. Whenever I have to search for the word "filter" it always brings me to the FFT or high-pass/low-pass filters. I want just to filter a column like Excel does, but my log file contains about half a million entries, so I can't fully open in Excel.

I've attached a screenshot of what some of my columns looks like, but for reasons of confidentiality, I can't reach the log file.

Someone at - it ideas?

Thank you!

Hi Ben,

I cooked up a small nice application for you.  Given that your post clearly stated that you were dealing with millions of data values, I took care to implement this request as efficiently as possible and to include State dialog boxes so that you know what the script is doing at any time and which actions are most of the time, where we try to further optimize your needs.  You must extract the 3 files in the ZIP file attached in the same folder somewhere.  Then you must run the script "ExtractIDGroups Add.VBS" to add the context menu and enter the UserCommands will call the context menu.  We can implement your tiara to always run this VBScript when you start, once you are satisfied with the result.

You will use the new context menu in the following way.  Load your data file in DIAdem, and then display the channels of data loaded in a table VIEW, like your screenshot posted.  Now select and right click on the channel "Arb ID" (or depending on the channel has the Hex addresses) and choose the new context menu "extract ID groups.  A user dialog box will pop up on the left of your computer screen lists all the listed final 2 Hex characters of suffix in this channel you clicked on.  Select one or more suffixes desired Hex (shift or control for a multiple selection key), and then click the button.  You will then see each of these selections exploded as a new group in your data portal.  You can select several times the "extract I groups" If you decide to go back and add a few ID groups more.

The application is currently being implemented to sort the raw data in place according to the values of "Hex suffix" and leave it this way - it so that leaving the channel 'Hex suffix' in the raw data group makes more quickly to repeat ID group gross since the same set of data extraction.  It's also the way more efficient to retrieve more than one ID groups, I'm guessing that you want to.  Each snippet ID Group is sorted by the values of the first chain of this group.  So if you want to sort these groups ID extracted by the string 'Abs Time' or "Time Rel", say, you need to drag this tri-canal in the data portal of his start position to the first position in this group of raw data before selecting the menu "Extract group ID".

Let me know how it works for you,

  • Error trying to filter the column named 'value' in the tab data

    I do not know it is because of the name of the column because all the other columns are working fine, but when I try to filter on the value = 60, I get an error:

    Is there a way I can filter this column? I tried quotes around column name, 'value' = 60, but that did not help.

    Thank you

  • Filter a column with the value of another

    Hello. Hope someone can help with this... On my search page, I want to use the value of the first list/drop-down menu to filter the values of the second list/menu. I use PHP and DW 8.0.2.

    Example: The first column has each of the 50 States. second column has 3 000 counties. If a user selects New Jersey, I want to just 21 NJ counties to appear as options in the second menu downwards rather than 3 000 counties.

    First Recordset works very well for the States. But in my second recordset, I say 'select distinct County of the said County WHERE AS var1'... and var1 is $recordset1 [County]. But the 2 column is empty. How can I actively pass the value of the first column in the second while the user is still on the same page?

    >>
    Assuming that your table has a field named "State":
    «select County of States WHERE state = "var1""

    You can use this solution when the first menu page 1 and the second menu on page 2 (IE passing the value of a query on page 2), but as assumingly, you need to have this functionality within a single page, basic need based on a javascript solution 'drop-down menus of dynamic load' to load the menu2 - options "in situs.

    Thank you

    If the column was purely digital, why cast to CHAR? The OP can do everything suggested Robert Angel. My suggestion was where there was some other non-numeric values in the column that could be the reason why the column is CHAR, then using the SIMILAR filter operand would solve this problem.

    The first part of your suggesting was not necessary if the column is a numeric data type and the second part was just a repetition of what Robert.

    Hello

    Simply connect a node that accepts data to the node to apply it.

    For example, if you want to create a view or table table using the prediction of outputs generated by the node to apply it, and then add a Create Table node and connect the node to apply it.

    For more information, try the Oracle by example tutorials for ODMr.

    You must use the node apply Publisher to revise prediction outputs models to generate as well as the additional columns to include, for example columns id.

    There are a set of predictor columns added by default that may be acceptable.

    The old packed timesheet application has the tip for how to display the day of the week selected by the user in the form of columns in the tabular presentation.

    Reference: old packages of timesheet Application

    That's how I'd do:

    • Select the range of dates populate the days between the date columns range in a collection of the APEX.
    • Display the columns as editable using the APEX_ITEM API.

    NOTE: Application of time sheets there was select list for weeks, so always the number of dynamic columns would be 7 + column code time.

    Also, the maximum number of modifiable columns, you can use on your page APEX is 50.
