I have created a database in anylogic. Previously, I have related the information in the row to the columnn, i.e. there is a component in the row, and its properties are in the columns, and have put this in a function. Now I want to make the component the column and the properties, but don't know how to make it all relate. Below is the code I've written for the former:
site = selectFrom(parameters) .where(parameters.box_number.eq(boxNumber)) .where(parameters.site.eq(site)) .firstResult(parameters.site);
So box_number is the component and site is one of the properties. With this method, site is a column, but I want it to be a row.
You should use the SELECT WHERE SQL syntax, see https://help.anylogic.com/index.jsp?topic=%2Fcom.anylogic.help%2Fhtml%2Fconnectivity%2Fquerying.html&resultof=%22%73%65%6c%65%63%74%22%20%22%77%68%65%72%65%22%20
You can filter and load data in any format. Also, best use the database query wizard to help:

I am using a DataGridPro component with different columns.
One one the columns is defined like this:
This issue is that I am trying to understand why the row is not available in the valueOptions prop of the column definition.
I would like to be able to populate the choices based on a list that is available on the row in another field.
But I get this error when I try to read the row:
Can you please help? The grid is populated with lots of rows coming from an api fetch.
Every other column is working fine accept this one.
Thank you.
I discovered that it was my bad. My column object was used twice with different parameters and so, yes, the row was not available for the second case.
In my model I want to loop through the database which contains multiple columns (see example) by an event. The idea behind it is that I want to create dynamic events based on the rows in the database.
But I've no clue how to iterate through a database in anylogic and also was not able to find an example of a loop with a database.
The dummycode of my problem would look something like this:
For order in orderdatabase:
Create order based on (order.name, order.quantity, order.arrivaltime, order.deliverylocation)
Where order in the loop is every row of the database, and the value on which the creation is based based on the different column values of that specific row.
Can somebody give me a simple example of how to create such a loop for this specific problem.
Thanks in advance.
Use the database query wizard:
put your cursor into a code field
this will allow you to open the database wizard
select what you need (in your case, you want the "iterate over returned rows and do something" option
Click ok
adjust the dummy code to make it do what you want
For details and examples, check the example models and the AnyLogic help, explaining all options in detail.
There's a working report but I wan't to change the visibility of certain rows based on a completely new DB select that should be executed when the report is created.
It would be ideal, if I could load the values of said select in an array or a list and than simply trigger certain row's visibility by comparing e.g. the Row Id with the values in the array.
Im used to solve a problem like this by creating a View that delivers all the essential information in each row and is used as the main data source but I was wondering if there's an elegant way within crystal reports to solve such a task.
I can think of three ways to include control data like this into the report:
One row of config data: If you can arrange it that your config data query returns one row of data, it can be just added to the data sources of the main report, without any links to tables and views already there.
Config resultset for matching: If you have to match main data results to config values row by row, e.g. by the Row Id you mentioned, add this config query to your report and link it to the main data source accordingly. (You are probably already doing this within your pre-created view on database side.)
Query config by subreport: Most flexible but also time consuming option is to add a subreport in report header, add the config data query and arrange config results into (shared) variables as needed in the subreport. Shared variable values can be used in main report then to control section visibility.
Yes, one of the 3rd-party Crystal Reports UFLs (User Function Libraries) listed here provides such a function.
My crystal report pulls data about books, including an identifier (isbn, issn order number etc.), author, and publisher.
The ID field stores multiple ways to identify the book. The report displays any of the identifiers for that record. If one book has two identifiers; issn and order number, the report currently displays one apparently at random.
How can I make it prioritise which type to use based on a preset order? I figured some sort of filter on the field could work, but I haven't figured out how. I can't edit the table, but I can use SQL within the report.
If all the different types of ID are stored in a single field, your best bet is to use a SQL Command inside your report to separate them into multiple virtual fields.
Go to Database Fields / Database Expert, expand the connection you want to use, and pick Add Command. From here you can write a custom SQL statement to grab the information you're currently using, and at the same time separate the ID field into multiple different fields (as far as the report will be concerned, anyway. The table will stay unchanged.)
The trick is to figure out how to write your command to do the separation. We don't know what your data looks like, so you're on your own from here.
Based on the very little information that you have provided and if i was to make a guess.I suggest you make use of the formula field in your report and then use something like this to accomplish your goal.
IF ISNULL{first_priority_field_name} OR {first_priority_field_name} = '' THEN
{second_priority_field_name}
ELSE
{first_priority_field_name}
Use nested IF statement in case there are more than 2 identifier fields.
I am new to JasperReports. I need to design a report where certain columns and rows are dynamic. For this how I have to design the report and after design i want to integrate with my application for fetching data from action class and dto. How to map data for its?
I don't know how dynamic it will be, but it may help you: http://dynamicjasper.com/
It uses JasperReports to generate your report and it also allow you to create your report on the fly.
There are 2 options to map data with the columns. First option is u can pass ur data into data Source binding with the column name as key value pair. And the second option is u can pass the obj of your dto to data source directly in list form.
Use report.setDataSource() for setting the data. In first option make sure your type of the data matches with the column name.
