I want to test my rules in drools. I have used Postman and Java client to test for single row of values and it shows my applied rules are working. However I want to use an entire csv file and check the rules for each row. Is there any way to achieve this in drool ?

I have built my model and run the experiment. I cannot seem to find where the data is stored.
I now need to conduct several runs and compare the results, I am using normally distributed repair times so the results should vary between runs without modifying parameters.
How can I keep the results of each run and then present them all in the same data set?
There are two main options for getting data out of your simulation
Using the internal AnyLogic database
Using external files like Excel or txt
Step 1: Setup your objects
Internal Database
Create an empty table with the columns you require
External object
Setup either an Excel or text file using the objects provided by AnyLogic in the Connectivity palette
Step 2: Saving your data
For both cases you need to write your data to the object of your choosing, either as the data gets generated or at the end of the simulation model
using Internal DB
The best option is to write data using the following command
insertInto(table_name)
.columns(column_name)
.values(value);
This will just insert a new line into a database table that you created, you can save multiple values to multiple columns by adding comma-separated entries into the parameters for columns and values.
e.g
insertInto(temeprature_output_table)
.columns(scenario_name, time, temperature)
.values("sceanrio1", 10,5, 102);
External files
2.1) Using Excel
filename.setCellValue(value, sheetName, row, column);
or even better you can write out an entire dataset
excelFile.writeDataSet(dataset, sheetName, row, column);
2.2) Using a text file
fileName.println("value" + "\t" + " value 2");
You can use whatever separator you want "\t" for tab separated or "," for comma and so on
Step 3: Finish and export data
Internal Database
At the end of a simulation run, you can simply export the data
See help here https://anylogic.help/anylogic/connectivity/export-excel.html#exporting-data-to-ms-excel-workbook
P.S. It is possible to automate this with some effort
External file
On Excel you need to call .writeFile() to finish.
On both objects, you need to call .close() for them to be closed and saved to memory.
FYI
Excel has the option to save on termination.

There is also an example model
I'm working on a talend job where I have a excel file and a couple of database fields that gets mapped to an XML file.
The working job looks like this:
Problem: I want to, with the same input of the excel file and the database fields, make another mapping that outputs to the same working XML file mentioned ealier. So I will have ONE XML file with TWO different mappings. How can I achieve this?
Update
I have done this mapping:
which in the end gets exported like this:
but I'm unsure on how to use this mapping in the tAdvancedFileOutputXML
If I understood correctly, you want to have a single XML file containing two different XMLs (the second one appended to the first one). In the shown Job add a OnSubJobOk link to point to a duplicate of your document flow which has a different mapping. In the second flow rather than using tFileOutputXML component to write the XML file, you can use the tAdvancedFileOutputXML with Append Source XML File marked to add to the file generated from the first flow. Also make sure to configure the XML tree. Check the following link for further information https://help.talend.com/reader/~hSvVkqNtFWjDbBHy0iO_w/h3wZegFH1_1XfusiUGtsPg
Hope this helps.
I'm new to Talend, I just did some test.
I created a simple job that query SQL Server and writes on a xlsx file.
Query returns one record (tested on SSMS). And job seems to run fine:
It creates output files, names it correctly and, if specified, it also writes header in it.
But it does not write the record.
Mapping is one to one with the guessed schema. No filter or other operations on data.
What can I check?
== Edit - xlsx configuration ==
As we discover together, you need to replace your tMSSqlRow by a tMSSqlInput component in your job.

I have a number of excel files where there is a line of text (and blank row) above the header row for the table.
What would be the best way to process the file so I can extract the text from that row AND include it as a column when appending multiple files? Is it possible without having to process each file twice?
Example
This file was created on machine A on 01/02/2013
Task|Quantity|ErrorRate
0102|4550|6 per minute
0103|4004|5 per minute
And end up with the data from multiple similar files
Task|Quantity|ErrorRate|Machine|Date
0102|4550|6 per minute|machine A|01/02/2013
0103|4004|5 per minute|machine A|01/02/2013
0467|1264|2 per minute|machine D|02/02/2013
I put together a small, crude sample of how it can be done. I call it crude because a. it is not dynamic, you can add more files to process but you need to know how many files in advance of building your job, and b. it shows the basic concept, but would require more work to suite your needs. For example, in my test files I simply have "MachineA" or "MachineB" in the first line. You will need to parse that data out to obtain the machine name and the date.
But here is how may sample works. Each Excel is setup as two inputs. For the header the tFileInput_Excel is configured to read only the first line while the body tFileInput_Excel is configured to start reading at line 4.
In the tMap they are combined (not joined) into the output schema. This is done for the Machine A Excel and Machine B excels, then those tMaps are combined with a tUnite for the final output.
As you can see in the log row the data is combined and includes the header info.
I need to track state change of an object and fire rules based on output of previous rule output, the examples I got from google results all use, accumulate function to track state. These were in DRLs but I want to do the same with Excel rules table, can anyone provide example or links?
