Hi ,

I am retrieving data from DB having column as ID ,TEXT

but when I provide data to Process Document from Data operator , it gives me Row No TEXT and different word counts as columns .

I need ID column as well , so that I can update the database for the same IDs .

Hey Ankit,

adding a Set Role operator before process documents and assigning the id role to the ID attribute should do the job.

Thanks for your reply.

I am reading from a database having id column using Read Database operator, applying o/p of this to SET Role Operator and then output of role operator is applied to Process document in which tokenizing, stemming, filterting and n gram generation are performed.
Still not getting ID column at the output of process document.

Hey,

please post your process setup, there must be something wrong. For me, the output of Process Documents definitely still contains the id column. Also, please update both RapidMiner and the Text extension to the latest versions.
