[postgis-users] basic functionalities of PostGIS

[ΑΠΟΣΤΟΛΟΣ ΛΕΛΕΝΤΖΗΣ]

Nicklas, firstly thanks for your reply.

Indeed, i understand the power of spatial SQL, but now i am a beginner, and
i need a lot of work.

As i mentioned, i want to union two layers, typing a spatial SQL query.
I want to take the same result, if i use the tool union of ArcGIS. But, i
don't like to talk with terminal of ArcGIS, so i want to execute one of the
classic spatial action, namely UNION (A or B).
Because, i can't type the right command..could you help me???

Thank you again
Apostolis
