Re: how to generate dynamic csv file with a column data

Hi,
If I understand your requirement well, you are looking for a dynamic filename in tfileoutputdelimited component with table column name.
To make it clear, I have designed a demo job for you.
table:
id;place
1;a
2;b
There should be two .csv generated files a.csv and b.csv in folder.
Please see my screenshots for details
Best regards
Sabrina

Re: how to generate dynamic csv file with a column data

you can design job your job like below.

your Input---tJavaRow----tFileOuputDelimited.
1. create variable for Group Name to hold the group name( context.GroupName)
2. in tjavaRow assign Group name to context variable like
context.GroupName=inputrow.groupName;

3. in tFileOutputDelimited components basic setting used context variable.
 "your filePath"+context.GroupName+"yourfileextention" 
like "c:/mydir/"+context.GroupName+".csv"

hope I explain well and it meets to your requirement.
