Is it possible to create different set of reports , to analyse the different set of data from one data source ?

Welcome @pio,

did i get it right, that you want to include a table? If so, how would you like to format it in the mail? The most general and flexible solution would be to export data tables in pdf format as a BIRT report and then include it in the mail as an attachment. There is an example of this functionality here: https://hub.knime.com/knime/workflows/Examples/09_Enterprise/01_Server/01_Generate_a_Report_and_Save_the_File*otrQnFWuB99HdbML .

Thanks Misha for your reply. I am not looking to call a workflow and then create a pdf.
I have a work flow in which I have an email to send. As it can be seen in the screen shot, I have couple of variable ports already attached to the email. I want to include the table as well from the sorter (Node 108).
My question is how could I do that

Hi,

as you can see from the Send Email input port, one can not send a table directly into the mail. That’s why i was suggestion the linked example. In that suggestion you would separate the bottom branch in your screenshot into a new workflow that would receive a table as input and would generate a report in pdf format.that report can be then picked and attached to the mail.

Alternatively, you need to build a workaround. In a general case tables can be arbitrary large and thus dumping them into a mail body can be unwanted. If you have a small table, you can extract all its entries into flow variables (in the example in your original question that would lead to 10 variables) and then format those 10 values in the body of your mail.

Another idea could be to dump the table into a file in some remote shared repository and then send a link to it in the mail. You can use a KNIME Server or google spreadsheets or any other exchange means that are used in your organisation.

Cheers,
Misha

Hi @pio,

I learned from a colleague that it is also possible to format the table as HTML into a flow variable and then add that piece of html table to the email text using the variable. If that options sounds interesting for you, I can investigate and assemble an example.

Hi Lisovyi,
That sounds interesting. I would be interested in an example.

Hi @pio,

here is an example: table_html.knwf (16.7 KB). Note, that you can style the table and the text in general with usual tags in HTML. Resulting email body looks like this:

There’s a node that will do a conversion of a KNIME table to an HTML table for you without needing to use the column expressions:

It outputs as a cell in the output table as well as a string flow variable you can connect to the send email node (this is the purpose the node was originally written for).

Hi Pio

You need to install the Lhasa public plugin from the trusted community contribution which can be found in the Cheminformatics group from the trusted community update site.
