Hello Everyone,

I have recently started using Talend. I am trying to create and schedule a job that extracts data from a MySQL database and email the results.

This is what my Designer section looks like.

The data is being fetched BUT

Issue 1: instead of just one email, several emails are being generated with identical results.

I have used tJavaRow to incorporate some js into my job. To show the output in a table format, I have used html tags:

The email that is being received looks like this:

This is what my tJavaRow code looks like:

output_row.EngineID = input_row.EngineID;
output_row.Status = input_row.Status;



if (input_row.Status.equals("Server Was Rebooted!")){
	output_row.color = "Red";
}else 
	output_row.color = "Green";

	

String msg = ((String)globalMap.getOrDefault("mailMsg", "<table><tr><th>EngineID</th><th>Status</th><th>color</th></tr>"));
msg = msg +
 "<tr>" +
 "<td>" + output_row.EngineID + "</td>" +
 "<td>" + output_row.Status + "</td>" +
 "<td>" + output_row.color + "</td>" +
 "</tr>";

globalMap.put("mailMsg", msg);

Issue 2: why doesn't the email show the table borders? I have also tried inserting table border in my html tags? where can I put the css? it gives me errors when I place them in my tJavaRow component.

Any good practices that you would like to share with a newbie?

Hi
In this case, you should use tJavaFlex instead of tJavaRow, you can learn the difference between these two components in this article
https://community.talend.com/t5/Design-and-Development/What-is-the-difference-between-tJava-tJavaRow-and-tJavaFlex/ta-p/21505

And change your job to
tMysqlInput--main--tJavaFlex--main-tFileOutputDelimited
|onsubjobok
tSendMail

It will send only one email in the end of job.
