[resolved] Count number of rows in a file and sent the total in an email

[Anonymous]

Hello,
I am trying to count the number of rows in a file and send that total in an email.
So far my approach has been to use a tAggregateRow on the tFileOutput to get the count.  Is there a way using tSetGlobalVar to get the count value from the tAggretateRow and insert that into the “Message” section of the TSendMail?
My layout is as follows tFileOutput -> tAggregateRow -> tSetGlobalVar -> tSendMail
If this layout will work should the Value under tSetGlobaVar be set to something like “tAggregateRow”
Thanks

Wouldn't it be easier to use the tFileRowCount component?
You can display the result via tJava:
System.out.println(globalMap.get("tFileRowCount_1_COUNT"));

Hi,
You don't need to use the global variable. You can put in the tSendMail the value straight from tAggregateRow/tFileRowCount using following format: output_name.output_column_name (for example row1.count_rows).
If the returned count value is Integer you need to convert it to string String.valueOf(row1.count_rows).
