Hi

 

I am using an aggregator to group polygons by two different attributes. Fme returns no error and seems to work reasonable (494 obj. before, 44 obj. after aggregation) and reports 44 features written.

 

However the actual number in the db is still 494.

 

What am I missing?

Hi,

 

 

If you are going to update records in an existing DB table, all existing records other than updated records will also be preserved unless you delete them.

 

Isn't it such a situation?

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

Hi Takashi

 

 

Unfortunately no. The writer is in truncate mode, which deletes all existing records before updating.
