[Qgis-user] Editing Data in Attribute Table/How Do I Install

[Andreas Neumann]

 Hi Leyan,

 Are you aware that there is a tool in the advanced editing toolbar 
 called "Merge attributes of selected features". There are two identical 
 icons next to each other. One also merges the geometries into one 
 feature, the other one only sets all attributes of the selected features 
 to the same attributes. It assigns the same attribute values to all 
 features (except the primary key column). It allows you to set which of 
 the selected features is used or you can calculcate mean/max/min or the 
 most common attribute value.

 Hope this helps,
 Andreas
